Airworthiness Directives; Empresa Brasileira de Aeronautica S.A.
(EMBRAER) Model EMB-135 and -145 Series Airplanes
AGENCY: Federal Aviation Administration (FAA), Department of
Transportation (DOT).
ACTION: Final rule.
-----------------------------------------------------------------------
SUMMARY: This amendment adopts a new airworthiness directive (AD),
applicable to certain EMBRAER Model EMB-135 and -145 series airplanes.
This AD requires repetitive detailed inspections of the oil in the air
turbine starter (ATS) to determine the quantity of the oil and the
amount of debris contamination in the oil. If the oil quantity is
incorrect or if excessive debris is found in the oil, this AD requires
replacement of the ATS with a new or serviceable ATS, and continued
repetitive detailed inspections. This AD also requires eventual
replacement of each ATS with a new, improved ATS, which constitutes
terminating action for the repetitive detailed inspections. This action
is necessary to prevent a flash fire in the nacelle, which would result
in the flightcrew shutting down the engine during flight, and
consequent reduced controllability of the airplane. This action is
intended to address the identified unsafe condition.
DATES: Effective March 24, 2005.
The incorporation by reference of certain publications listed in
the regulations is approved by the Director of the Federal Register as
of March 24, 2005.
ADDRESSES: The service information referenced in this AD may be
obtained from Empresa Brasileira de Aeronautica S.A. (EMBRAER), P.O.
Box 343--CEP 12.225, Sao Jose dos Campos--SP, Brazil. This information

SUPPLEMENTARY INFORMATION: A proposal to amend part 39 of the Federal
Aviation Regulations (14 CFR part 39) to include an airworthiness
directive (AD) that is applicable to certain EMBRAER Model EMB-135 and
-145 series airplanes was published in the Federal Register on February
19, 2004 (69 FR 7707). That action proposed to require repetitive
detailed inspections of the oil in the air turbine starter (ATS) to
determine the quantity of the oil and the amount of debris
contamination in the oil. If the oil quantity was incorrect or if
excessive debris was found in the oil, that proposal would have
required replacement of the ATS with a new or serviceable ATS having
the same part number, and continued repetitive detailed inspections.
That proposal would also have required eventual replacement of each ATS
with a new improved ATS having a new part number, which would
constitute terminating action for the repetitive detailed inspections.
Actions Since Proposed AD Was Issued
Since we issued the proposed AD, we have determined that the
Departmento de Aviacao Civil (DAC), which is the airworthiness
authority for Brazil, issued two Brazilian airworthiness directives
that address that same unsafe condition. The DAC issued Brazilian
airworthiness directive 2001-09-04, dated October 10, 2001. The DAC
also issued Brazilian airworthiness directive 2003-07-01, Revision 01,
dated December 23, 2003. We issued a parallel proposed AD for each
Brazilian airworthiness directive. One proposed AD, Directorate
Identifier 2002-NM-352-AD, was published in the Federal Register on
December 18, 2003 (68 FR 243). The other proposed AD, Directorate
Identifier 2003-NM-237-AD, was published in the Federal Register on
February 19, 2004 (69 FR 7707).
Upon further evaluation, and based on comments received in response
to the proposed AD with Directorate Identifier 2002-NM-352-AD, we have
determined that it is in the best interest of the FAA and the U.S.
operators to combine the requirements of both of our proposed ADs into
this AD. The requirements in this AD adequately address the identified
unsafe condition specified in 2002-NM-352-AD. Accordingly, the proposed
AD with Directorate Identifier 2002-NM-352-AD will be withdrawn after
this AD is issued. The DAC and the airplane manufacturer support our
decision.
Comments
Interested persons have been afforded an opportunity to participate
in the making of this amendment. Due consideration has been given to
the comments received.
Request To Allow Part Number (P/N) 3505910-6 as a Replacement Part
Three commenters request that air turbine starter (ATS) P/N
3505910-6 be included in the proposed AD as an acceptable replacement
part. (The proposed AD states that an affected ATS should be replaced
with a new or serviceable ATS having P/N 3505910-4 or P/N 3505910-5.)
We agree with the commenters' requests. We have revised the Summary
section of this AD by deleting the text that states that the ATS should
be replaced with an ATS having the same part number. Paragraph (d) of
this AD has been revised to include P/N 3505910-6 as an additional
acceptable replacement part.
Request To Allow Replacement of ATS Within 50 Hours Instead of Before
Further Flight
Two commenters request that the proposed AD be revised so that, if
the results of an inspection of the oil indicate that the ATS should be
replaced, operators may continue to use that ATS for an additional 50
flight hours before doing the replacement. (Paragraph (d) of the
proposed AD specifies that that the ATS should be replaced prior to
further flight.) One commenter states that the 50-hour grace period
should be acceptable because Brazilian airworthiness directive 2003-07-
01R1, dated December 23, 2003, allows ATS units that don't show
evidence of wear or failure to go back into service for 50 flight hours
before replacement. The commenter also states that, based on service
history, the additional 50 flight hours is very conservative. The other
commenter states that EMBRAER Service Bulletin 145-80-0005, Revision
02, dated September 16, 2003, allows a grace
[[Page 8029]]
period of 50 flight hours, and that operators incorporating that
service bulletin have not reported failures or service interruptions
within 50 hours of the service inspection.
We agree to allow a 50-hour grace period for ATSs that meet the
criteria specified in EMBRAER Service Bulletin 145-80-0005, Revision
02. We misinterpreted the Brazilian airworthiness directive and, in the
proposed AD, identified the 50-hour grace period as a difference
between the proposed AD and the Brazilian airworthiness directive. We
have determined that a 50-hour grace period will allow airplanes to
continue to operate without compromising safety. Paragraph (d) of this
AD has been revised to specify that an ATS should be replaced at the
times specified in the applicable service bulletin.
Request To Change Compliance Time for Initial Inspection
One commenter requests that the FAA revise the compliance time for
the initial detailed inspection specified in paragraph (b) of the
proposed AD. The commenter provides two suggestions for making this
change. The first suggestion is to either delete the statement
``whichever comes first'' or change that statement to ``whichever comes
later.'' The second suggestion is to change the initial inspection
threshold from ``Within 200 flight hours or 90 days'' to ``Within 500
flight hours or 180 days.'' The commenter states that it is already
accomplishing the intent of the proposed AD. Since August 2003, the
commenter has repetitively inspected the ATS in its fleet of airplanes
at intervals of 500 flight hours. The commenter contends that, by
changing the threshold for the initial inspection in the proposed AD,
the FAA and the commenter would conserve resources regarding the
processing of requests for alternative methods of compliance (AMOCs)
related to the compliance time for the initial detailed inspection.
We do not agree with the commenter's request to change the
threshold for the initial detailed inspection. In developing an
appropriate threshold for this AD, we considered the safety
implications, the manufacturer's recommendations, the Brazilian
airworthiness authority's recommendations, and operators' maintenance
schedules. Under the provisions of paragraph (g) of this AD, however,
we may consider requests for adjustments to this compliance time if
data are submitted to substantiate that such an adjustment would
provide an acceptable level of safety.
Request To Include Secondary Test for Certain ATSs
One commenter notes that Brazilian airworthiness directive 2003-07-
01R1 includes a provision that a new ATS should not be replaced during
the first 400 hours of operation after installation if oil system
debris is detected during an inspection. The proposed AD does not
include that provision. The commenter states that metallic debris is
normal during the ``wear-in'' of a new ATS. Such debris does not
necessarily indicate abnormal wear or imminent failure of the part. The
commenter also states that EMBRAER Service Bulletins 145-80-0005,
Revision 02, dated September 16, 2003; and 145LEG-80-0001, Revision 01,
dated April 10, 2003; include a secondary test (referred to as a
``penalty run'' in the service bulletins) that should be conducted on
new ATSs that show metallic particles on the magnetic drain plug.
(Those service bulletins were cited in the proposed AD as acceptable
sources of service information for inspecting the ATS.) The results of
the secondary test will help operators determine if metal debris is a
result of the normal ``wear-in'' period or abnormal ATS wear, or is
from a different part of the engine.
We agree that, if an ATS has less than 400 flight hours since new
or last overhaul, operators should be allowed the option of performing
the secondary test. This option allows airplanes to continue to operate
without compromising safety. Paragraph (d) of this AD has been revised
to allow operators the option of replacing the ATS before further
flight or performing the secondary test in accordance with the
applicable service bulletin.
Request To Include Additional Service Information
One commenter requests that the proposed AD be revised to require
operators to incorporate Rolls-Royce Service Bulletin AE 3007A-72-253,
dated September 13, 2002. The commenter states that the Rolls-Royce
service bulletin includes procedures for installing a vented quick
access drain (QAD) adapter. The QAD adapter alleviates a contributing
cause of the ATS failure.
We partially agree. We agree that installing the QAD adapter
alleviates a contributing cause of the ATS failure; however, we will
not revise this AD to require operators to perform the actions in the
Rolls-Royce service bulletin. The parallel Brazilian airworthiness
directive does not require operators to incorporate the Rolls-Royce
service bulletin, and the associated EMBRAER service bulletins include
procedures for operators that have incorporated the Rolls-Royce service
bulletin and procedures for operators that have not incorporated the
Rolls-Royce service bulletin. Also, operators may voluntarily
incorporate the Rolls-Royce service bulletin. No change has been made
to this AD regarding this issue.
The same commenter states that requiring the EMBRAER EMB-135 and -
145 fleet to install P/N 3505910-6 within two years after the effective
date of the proposed AD is an unnecessary hardship given the
improvements made by incorporating the Rolls-Royce service bulletin.
The commenter states that the procedures in the Rolls-Royce service
bulletin include removing the drain cap, which would attenuate the oil
migration and seal damage, making the potential for a low-oil/backdrive
failure much less likely. The commenter notes that it took operators
almost a year to accomplish the ``simple'' Rolls-Royce service
bulletin. We infer that the commenter requests an extension of the
compliance time specified in paragraph (e) of the proposed AD.
We do not agree to extend the compliance time in paragraph (e) of
this AD. Although the preventative measures provided in the Rolls-Royce
service bulletin address the primary cause of backdrive events, other
contributing causes of backdrive events still exist. Also, the
commenter did not provide data that substantiate that all operators
have incorporated the Rolls-Royce service bulletin. Furthermore, the
parallel Brazilian airworthiness directive specifies that all ATS P/Ns
3505910-4 and -5 should be replaced with ATS, P/N 3505910-6, before
March 1, 2006. Since we do not use calendar dates in the compliance
times for our ADs, we considered the safety implications, the
manufacturer's recommendations, and the Brazilian airworthiness
authority's recommendations, and determined that accomplishment of the
part replacement within 26 months after the effective date of the AD
represents an appropriate interval of time for affected airplanes to
continue to operate without compromising safety. However, under the
provisions of paragraph (g) of this AD, we may consider requests for
adjustments to the compliance time if data are submitted to
substantiate that such an adjustment would provide an acceptable level
of safety.
Request To Clarify Unsafe Condition
Two commenters mention that the unsafe condition statement in the
proposed AD is inaccurate. One commenter states that the unsafe
[[Page 8030]]
condition statement implies that a fire in an engine section is a
direct cause of the engine shutdown, when actually a fire started by an
ATS would be detected by the fire detection system and annunciated to
the flightcrew. The engine shutdown is a result of the flightcrew's
response to the fire. The other commenter states that the phrases
``prevent a flash fire'' and ``cause the engine to shut down'' are
incorrect. The commenter notes that the improved ATS, P/N 3505910-6,
prevents ATS backdrive failures. The commenter states that backdrive
failures do not necessarily result in a flash fire or always result in
engine shutdown. We infer that the commenters are requesting that the
unsafe condition statement in the proposed AD be revised.
We agree that the unsafe condition statement implies that a fire in
an engine section directly causes an engine shutdown. We do not agree
that the phrases ``prevent a flash fire'' and ``cause the engine to
shut down'' are incorrect. The end result of the unsafe condition is
the possibility of a flash fire and an engine shutdown. The intent of
this AD is to require operators to install the new, improved ATS, P/N
3505910-6, which prevents the ATS backdrive failures. Therefore, until
operators install P/N 3505910-6, the possibility of a flash fire and
engine shutdown still exists. The unsafe condition statement in this AD
has been revised to state: ``To prevent a flash fire in the nacelle,
which would result in the flightcrew shutting down the engine during
flight, and consequent reduced controllability of the airplane.''
Request To Allow Alternative Method for Repetitive Inspections
One commenter states that it services the ATS oil system of its
fleet every routine check (7 days), as specified in Subtask 80-10-01-
610-001-A00, dated August 28, 2004, in Chapter 80-10-01 of the EMBRAER
EMB-145 Aircraft Maintenance Manual (AMM). The commenter asks if it is
acceptable to the FAA to continue this practice. We infer that the
commenter is requesting to perform the repetitive inspections in the
AMM instead of the repetitive detailed inspections specified in
paragraph (b) of this AD.
It is acceptable for the commenter to continue doing the procedures
specified in Subtask 80-10-01-610-001-A00. However, after reviewing the
subtask, we have determined that those procedures do not satisfy the
requirements of this AD. The procedures in the subtask are for
determining the oil level of the ATS, not for inspecting the oil in the
ATS for debris. As provided by paragraph (g) of this AD, the commenter
may apply for an AMOC.
Request To Omit Repetitive Inspections
One commenter supports the issuance of the proposed AD but raises
several questions. The commenter questions the purpose of including
repetitive inspections in the proposed AD. The commenter also asks if
180 ``hours'' between inspections is too much time. The commenter notes
that if abrasive particles become suspended in a lubricating substance
within the first 90 days, there is an ineffective lubrication system
for 90 more days. The commenter also proposes several solutions for
addressing the unsafe condition of debris in the oil of the ATS. The
commenter states that requiring the immediate replacement of the ATS
when the AD is published would be more cost effective than requiring
repetitive inspections and eventual replacement of the ATS. The
commenter states that the immediate part replacement would also be
safer. We infer that the commenter is requesting that the proposed AD
be revised to omit the repetitive inspections specified in paragraph
(b) of that AD, and to mandate only the replacement of any ATS having
P/N 3505910-4 or P/N 3505910-5 with an ATS having P/N 3505910-6, as
specified in paragraph (e) of that AD. We also infer that the commenter
is requesting a reduction of the compliance time for the repetitive
inspection intervals.
We do not agree that the repetitive inspections of the ATS oil
should be deleted from paragraph (e) of this AD, or that the compliance
time for the repetitive inspection intervals should be reduced. Also,
the repetitive inspection interval specified in paragraph (b) of this
AD is 180 days, not 180 hours. The commenter did not provide any data
to substantiate the termination of the repetitive inspections of the
oil in the ATS, or the reduction of the compliance time for the
repetitive inspection intervals. Both the Brazilian airworthiness
directive and EMBRAER Service Bulletins 145-80-0005, Revision 02, dated
September 16, 2003; and 145LEG-80-0001, Revision 01, dated April 10,
2003; include provisions for repetitive inspections. The Brazilian
airworthiness directive mandates the detailed inspections at intervals
of 500 flight hours or 180 days, whichever occurs first. We have
determined that the repetitive inspections are needed to ensure the
continued operational safety of the affected airplanes. No change has
been made to this AD regarding these issues.
Request To Delete Note Regarding Submission of Information
One commenter states that the proposed AD mentions that Honeywell
Service Bulletin 3505910-80-1789, dated August 19, 2003, specifies to
submit certain information to Honeywell. (That service bulletin was
referenced as an additional source of service information in the
proposed AD.) The commenter states that Service Bulletin 3505910-80-
1789 has been revised and no longer requests operators to submit
information to Honeywell. We infer that the commenter is requesting
that the references to submitting certain information to Honeywell be
deleted from the proposed AD.
We do not agree to revise this AD regarding the submission of
information to Honeywell. To date, we have not received a copy of the
revised service bulletin and to our knowledge the revised service
bulletin has not been issued. Furthermore, when the revised service
bulletin is issued, the requirements of this AD will not be affected by
the omission of the request to submit information to Honeywell. Since
the Honeywell service bulletin is cited as a secondary source of
service information in this AD, it is referenced in a note. Notes in
ADs provide additional information only and do not include
requirements. No change has been made to this AD regarding this issue.
Conclusion
After careful review of the available data, including the comments
noted above, we have determined that air safety and the public interest
require the adoption of the rule with the changes described previously.
We have determined that these changes will neither increase the
economic burden on any operator nor increase the scope of the AD.
Cost Impact
We estimate that 459 airplanes of U.S. registry will be affected by
this AD, that it will take approximately 1 work hour per airplane to
inspect the oil in the ATS, and that the average labor rate is $65 per
work hour. Based on these figures, the cost impact of the AD on U.S.
operators is estimated to be $29,835, or $65 per airplane, per
inspection cycle.
We estimate it will take approximately 2 work hours per airplane to
replace the ATS, and that the average labor rate is $65 per work hour.
Based on these figures, the cost impact of the replacement on U.S
operators is estimated to be $59,670, or $130 per airplane.
[[Page 8031]]
The cost impact figures discussed above are based on assumptions
that no operator has yet accomplished any of the requirements of this
AD action, and that no operator would accomplish those actions in the
future if this AD were not adopted. The cost impact figures discussed
in AD rulemaking actions represent only the time necessary to perform
the specific actions actually required by the AD. These figures
typically do not include incidental costs, such as the time required to
gain access and close up, planning time, or time necessitated by other
administrative actions.
Authority for This Rulemaking
The FAA's authority to issue rules regarding aviation safety is
found in Title 49 of the United States Code. Subtitle I, Section 106,
describes the authority of the FAA Administrator. Subtitle VII,
Aviation Programs, describes in more detail the scope of the agency's
authority.
This rulemaking is promulgated under the authority described in
Subtitle VII, Part A, Subpart III, Section 44701, ``General
requirements.'' Under that section, Congress charges the FAA with
promoting safe flight of civil aircraft in air commerce by prescribing
regulations for practices, methods, and procedures the Administrator
finds necessary for safety in air commerce. This regulation is within
the scope of that authority because it addresses an unsafe condition
that is likely to exist or develop on products identified in this AD.
Regulatory Impact
The regulations adopted herein will not have a substantial direct
effect on the States, on the relationship between the national
Government and the States, or on the distribution of power and
responsibilities among the various levels of government. Therefore, it
is determined that this final rule does not have federalism
implications under Executive Order 13132.
For the reasons discussed above, I certify that this action (1) is
not a ``significant regulatory action'' under Executive Order 12866;
(2) is not a ``significant rule'' under DOT Regulatory Policies and
Procedures (44 FR 11034, February 26, 1979); and (3) will not have a
significant economic impact, positive or negative, on a substantial
number of small entities under the criteria of the Regulatory
Flexibility Act. A final evaluation has been prepared for this action
and it is contained in the Rules Docket. A copy of it may be obtained
from the Rules Docket at the location provided under the caption

Service Bulletin Reference
(a) The term ``service bulletin,'' as used in this AD, means the
Accomplishment Instructions of the following service bulletins, as
applicable:
(1) For the detailed inspection and replacements specified in
paragraphs (b), (c) and (d) of this AD: For Model EMB-135 BJ series
airplanes, EMBRAER Service Bulletin 145LEG-80-0001, Revision 01,
dated April 10, 2003; and for all other affected airplanes, EMBRAER
Service Bulletin 145-80-0005, Revision 02, dated September 16, 2003.
(2) For the replacement specified in paragraph (e) of this AD:
For Model EMB-135 BJ series airplanes, EMBRAER Service Bulletin
145LEG-80-0002, dated October 2, 2003; and for all other affected

2003.
Note 1: These service bulletins refer to Honeywell Service
Bulletin 3505910-80-1789, dated August 19, 2003, as an additional
source of service information. The Honeywell service bulletin is
included in the EMBRAER service bulletins. Although this Honeywell
service bulletin specifies to submit certain information to the
manufacturer, this AD does not include such a requirement.
Repetitive Detailed Inspection
(b) Within 200 flight hours or 90 days after the effective date
of this AD, whichever occurs first: Perform a detailed inspection of
the oil in the air turbine starter (ATS) to determine the quantity
of oil and to determine the amount of debris contamination in the
oil in accordance with the applicable service bulletin. Repeat the
inspection at intervals not to exceed 500 flight hours or 180 days,
whichever occurs first.
Note 2: For the purposes of this AD, a detailed inspection is
defined as: ``An intensive visual examination of a specific
structural area, system, installation, or assembly to detect damage,
failure, or irregularity. Available lighting is normally
supplemented with a direct source of good lighting at intensity
deemed appropriate by the inspector. Inspection aids such as mirror,
magnifying lenses, etc., may be used. Surface cleaning and elaborate
access procedures may be required.''
Oil Replacement if Oil Quantity Is Correct and No Excessive Debris Is
Found
(c) If, during the inspection required by paragraph (b) of this
AD, no oil debris contamination is found that is in excess of the
limits allowed by the applicable service bulletin; and if the amount
of oil in the ATS is correct: Prior to further flight, replace the
oil in the ATS with new oil, in accordance with the applicable
service bulletin.
ATS Replacement if Oil Quantity Is Incorrect or if Excessive Debris Is
Found
(d) If, during the inspection required by paragraph (b) of this
AD, the oil quantity is found to be incorrect; or if oil debris
contamination is found that is in excess of the limits allowed by
the applicable service bulletin: Replace the ATS with a new or
serviceable ATS having part number (P/N) 3505910-4, P/N 3505910-5,
or P/N 3505910-6, at the times specified in and in accordance with
the applicable service bulletin. If an affected ATS has less than
400 flight hours since new or last overhaul, the ``penalty run''
test may be performed before further flight and the ATS replaced at
the times specified in and in accordance with the applicable service
bulletin.
Terminating Action
(e) Within 26 months after the effective date of this AD,
replace any ATS having P/N 3505910-4 or -5 with a new ATS having P/N
3505910-6 in accordance with the applicable service bulletin. This
replacement constitutes terminating action for the repetitive
detailed inspections required by paragraph (b) of this AD.
Actions Accomplished per Previous Issue of Service Bulletin 145-80-0005
(f) Actions accomplished before the effective date of this AD
per EMBRAER Service Bulletin 145-80-0005, Revision 01, dated April
10, 2003, are considered acceptable for compliance with the
corresponding actions specified in this AD.
