14 CFR Part 39

[Docket No. FAA-2005-21713; Directorate Identifier 2005-NM-085-AD;
Amendment 39-14732; AD 2006-17-11]

Airworthiness Directives; Boeing Model 767-400ER Series Airplanes
and Model 777-200 and -300 Series Airplanes

AGENCY: Federal Aviation Administration (FAA), Department of
Transportation (DOT).

ACTION: Final rule.

-----------------------------------------------------------------------

SUMMARY: The FAA is adopting a new airworthiness directive (AD) for
certain Boeing Model 767-400ER series airplanes and Model 777-200 and -
300 series airplanes. This AD requires, for certain airplanes,
repetitive testing of the fill and safety fittings of the cargo fire
extinguishing bottles in the forward cargo compartment for leaks; and
repetitive application of a corrosion inhibiting compound (CIC) or
replacement of the cargo fire extinguishing bottles with reworked fire
extinguishing bottles, as necessary. For all airplanes, this AD
requires replacement of the cargo fire extinguishing bottles with
reworked fire extinguishing bottles, which ends the repetitive tests
and CIC applications if applicable. This AD results from failure of the
safety fittings for the cargo fire extinguishing bottles. We are
issuing this AD to prevent failure of the safety fittings for the cargo
fire extinguishing bottles due to corrosion, which could result in
leakage of extinguishing agent. If a fire occurs in the cargo bay, the
cargo fire extinguishing bottles could have less than enough
extinguishing agent to control a fire.

DATES: This AD becomes effective September 27, 2006.
The Director of the Federal Register approved the incorporation by
reference of certain publications listed in the AD as of September 27,
2006.

Discussion

The FAA issued a notice of proposed rulemaking (NPRM) to amend 14
CFR part 39 to include an AD that would apply to certain Boeing Model
767-400ER series airplanes and Model 777-200 and -300 series airplanes.
That NPRM was published in the Federal Register on July 5, 2005 (70 FR
38632). That NPRM proposed to require, for certain airplanes,
repetitive testing of the fill and safety fittings of the fire
extinguishing bottles in the forward cargo compartment for leaks; and
repetitive application of a corrosion inhibiting compound (CIC) or
replacement of the fire extinguishing bottles with reworked fire
extinguishing bottles, as necessary. That NPRM also proposed to
require, for all airplanes, replacement of the fire extinguishing
bottles with reworked fire extinguishing bottles, which would end the
repetitive tests and CIC applications if applicable.

Actions Since NPRM Was Issued

Since we issued the NPRM, Boeing has published Special Attention
Service Bulletin 767-26-0124, Revision 1, dated April 13, 2006. We
referenced the original issue of that service bulletin, dated December
5, 2002, in the NPRM as the appropriate source of service information
for testing the cargo fire extinguishing bottles on Model 767-400ER
series airplanes. The procedures in Revision 1 of the service bulletin
are essentially the same as those in the original issue. Revision 1
corrects a reference to the Boeing 767 Aircraft Maintenance Manual
(AMM), which we noted as a difference in the NPRM. Therefore, we have
revised this AD to reference Revision 1 of the service bulletin as the
appropriate source of service information for testing the cargo fire
extinguishing bottles on Model 767-400ER series airplanes. We have also
added a new paragraph (k) to this AD, giving credit for testing done
before the effective date of this AD in accordance with the original
issue of the service bulletin. We have reidentified the subsequent
paragraphs accordingly.

Comments

We provided the public the opportunity to participate in the
development of this AD. We have considered the comments received.

Request for Credit for Additional Model Airplanes

Boeing requests that we revise paragraph (j) of the NPRM to include
Model 767-400ER series airplanes and Model 777-300 series airplanes.
(The NPRM provided credit only for Model 777-200 series airplanes.) As
justification, Boeing states that this change will provide credit for
all three affected model airplanes, not just the Model 777-200 series
airplanes. We infer Boeing would like credit for accomplishment of
Boeing Special Attention Service Bulletin 767-26-0124, dated December
5, 2002, for Model 767-400ER series airplanes; and Boeing Special
Attention Service Bulletin 777-26-0034, dated January 22, 2004, for
Model 777-300 series airplanes.
We agree to provide credit for all Model 767-400ER series
airplanes. As stated previously, we have given credit to Model 767-
400ER series airplanes in paragraph (k) of this AD.
We agree only to provide credit for certain Model 777-300 series
airplanes. Certain Model 777-300 series airplanes were misidentified as
Group 1 airplanes in the original issue of Boeing Special Attention
Service Bulletin 777-26-0034. Revision 1 of Boeing Service Bulletin
777-26-0034, dated July 1, 2004, states that more work is necessary on
Model 777-300 series airplanes if the Group 1 instructions of the
original service bulletin were accomplished on those airplanes.
However, no additional work is necessary for Model 777-300 series
airplanes if the Group 2 instructions of the original service bulletin
were accomplished on those airplanes. Therefore, we have revised
paragraph (j) of this AD to give credit only for Model 777-300 series
airplanes identified as Group 2 in the original issue of the service
bulletin. Under the provisions of paragraph (l) of this AD, we may
consider requests for approval of an alternative method of compliance
(AMOC) if sufficient data are submitted to substantiate that such a
method

[[Page 49329]]

would provide an acceptable level of safety.

Request To Clarify the Affected Fire Extinguishing Bottles

Boeing requests that we specifically refer to ``cargo'' fire
extinguishing bottles in the NPRM. As justification, Boeing states that
this will avoid confusion with the fire extinguishing bottles for the
engine/auxiliary power unit. We agree and have revised all references
accordingly in this AD.

Request To Revise Terminology

Boeing states that the safety disc inside the fill fitting is
referred to as ``fill and safety fittings,'' ``safety fittings,'' or
``burst disc inside the safety fitting'' in several paragraphs in the
NPRM. Boeing requests that we revise the NPRM to use its preferred
terminology of ``safety disc inside the fill fitting.''
We agree and have revised the terminology in paragraph (g)(1) of
this AD. We point out that we used the term ``burst disc inside the
safety filling'' in the NPRM to match the terminology used in the
referenced Boeing and Kidde Aerospace service bulletins for replacing
the cargo fire extinguishing bottles. We have continued using the term
``fill and safety fittings'' in paragraph (g) of this AD as it is
specified in the applicable Kidde Aerospace service bulletins.

Request To Revise Model Designation

Boeing also requests that we fix the typographical error for the
model designation in the first row of the Estimated Costs table of the
NPRM. Boeing states the correct model designation is Model 767-400ER.
We agree and have revised the Estimated Costs table in this AD
accordingly.

Request To Revise ``Discussion'' Section

Boeing also requests that we revise the first sentence of the first
paragraph in the Discussion section of the NPRM as follows:

We have received a report indicating that failed safety fittings
of the fire extinguishing bottles located in the forward lower lobe.
* * *.
The commenter also requests that we change the second paragraph of
the Discussion section to the following:

The cargo fire extinguishing bottles installed on Model 767-
400ER series airplanes are identical to metered cargo fire bottles
on the 777-300 series airplanes. Therefore, all of these models are
subject to the same unsafe condition.

As justification for the second part of its request, Boeing states
that all the cargo fire extinguishing bottles installed on Model 767-
400ER series airplanes are identical to one of the bottles that is
installed on Model 777-300 series airplanes, but not installed on Model
777-200 series airplanes.
We agree with Boeing's statements. However, the Discussion section
of an NPRM is not restated in the AD. Therefore, no change to this AD
is necessary in this regard.

Request To Identify the Affected Cargo Fire Extinguishing Bottles

The Modification and Repair Parts Association (MARPA) requests that
we include sufficient information to specify the precise applicability
of the NPRM. MARPA states that the NPRM relies on certain Boeing and
Kidde Aerospace service bulletins that were not incorporated by
reference when the NPRM was published in the Federal Register. Since
these service bulletins are copyrighted material, MARPA states it
cannot determine the precise applicability of the NPRM. We infer the
commenter would like us to identify the affected cargo fire
extinguishing bottles in this AD.
We do not agree to specify the affected part numbers in this AD. It
is our general practice to reference the appropriate service
information, since the affected part numbers are clearly specified in
that referenced information. Not only does it appear redundant to
repeat those part numbers in this AD, but if there was a large number
of parts involved, it would increase the risk of error in repeating
those part numbers in this AD. However, we are currently in the process
of reviewing issues surrounding the posting of service bulletins on the
Department of Transportation's Docket Management System (DMS) as part
of an AD docket. Once we have thoroughly examined all aspects of this
issue and have made a final determination, we will consider whether our
current practice needs to be revised. However, we consider that to
delay this AD action would be inappropriate, since we have determined
that an unsafe condition exists and that replacement of certain parts
must be accomplished to ensure continued safety. Therefore, no change
has been made to this AD in this regard.

Request To Reference Parts Manufacturer Approval (PMA) Parts

MARPA also requests that we add language to the NPRM to account for
the possible existence of alternative PMA equivalent parts. MARPA
states that, under 14 CFR 21.303, there may be PMA parts that should
also be affected by the NPRM. As justification, MARPA states that some
PMA parts appear to be similar to the affected parts addressed in the
NPRM, and that further research should be conducted to ensure that all
affected parts are included in the NPRM. MARPA further states that
there may also be PMA parts equivalent to the ``new and improved''
replacement parts specified in the NPRM.
We concur with MARPA's general request that, if we know that an
unsafe condition also exists in PMA parts, the AD should address those
parts, as well as the original parts. At this time, we are not aware of
other PMA parts equivalent to the affected cargo fire extinguishing
bottles.
Furthermore, we infer that MARPA would like the AD to permit
installation of any equivalent PMA parts so that it is not necessary
for an operator to request approval of an AMOC in order to install an
``equivalent'' PMA part. Whether an alternative part is ``equivalent''
in adequately resolving the unsafe condition can only be determined on
a case-by-case basis, based on a complete understanding of the unsafe
condition. We are not currently aware of any such parts. Our policy is
that, in order for operators to replace a part with one that is not
specified in the AD, they must request an AMOC. This is necessary so
that we can make a specific determination that an alternative part is
or is not susceptible to the same unsafe condition.
MARPA's remarks are timely in that the Transport Airplane
Directorate currently is in the process of reviewing this issue as it
applies to transport category airplanes. We acknowledge that there may
be other ways of addressing this issue to ensure that unsafe PMA parts
are identified and addressed. Once we have thoroughly examined all
aspects of this issue, including input from industry, and have made a
final determination, we will consider whether our policy regarding
addressing PMA parts in ADs needs to be revised. We consider that to
delay this AD action would be inappropriate, since we have determined
that an unsafe condition exists and that replacement of certain parts
must be accomplished to ensure continued safety. Therefore, no change
has been made to this AD in this regard.

Request To Delete Difference Paragraph

Boeing states that it intends to publish Revision 1 to Boeing
Special Attention Service Bulletin 767-26-0124 to correct the reference
to the AMM, which we identified as a difference in the NPRM. Boeing
also states that Revision 1 is currently being routed for approval. We
infer the commenter would like us to

[[Page 49330]]

delete the difference paragraph. We disagree, since the difference
paragraph is not restated in this AD. Since we have already revised
this AD to reference Revision 1 of the service bulletin, as described
previously, no additional change to this AD is necessary.

Request To Revise the Costs of Compliance Paragraph

American Airlines states that the total cost for testing the cargo
fire extinguishing bottles as specified in Boeing Special Attention
Service Bulletin 777-26-0033, dated December 5, 2002, is $5,460, per
test cycle. The commenter also states that the total cost for replacing
the cargo fire extinguishing bottles as specified in Boeing Service
Bulletin 777-26-0034, Revision 1, dated July 1, 2004, is $287,573. We
infer that American Airlines would like us to revise the Costs of
Compliance paragraph.
We disagree. The cost information in an AD describes only the
direct costs of the specific actions required by the AD. Based on the
best data available, the manufacturer provided the number of work hours
necessary to do the required actions. This number represents the time
necessary to perform only the actions actually required by this AD. We
recognize that, in doing the actions required by an AD, operators may
incur incidental costs in addition to the direct costs. The cost
analysis in AD rulemaking actions, however, typically does not include
incidental costs such as the time required to gain access and close up,
time necessary for planning, or time necessitated by other
administrative actions. Those incidental costs, which may vary
significantly among operators, are almost impossible to calculate.
Therefore, no change has been made to this AD in this regard.

Clarification of AMOC Paragraph

We have revised this action to clarify the appropriate procedure
for notifying the principal inspector before using any approved AMOC on
any airplane to which the AMOC applies.

Conclusion

We have carefully reviewed the available data, including the
comments received, and determined that air safety and the public
interest require adopting the AD 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.

Costs of Compliance

There are about 322 airplanes of the affected design in the
worldwide fleet. This AD affects about 167 airplanes of U.S. registry.
The following table provides the estimated costs, at an average labor
rate of $65 per hour, for U.S. operators to comply with this AD.

Authority for This Rulemaking

Title 49 of the United States Code specifies the FAA's authority to
issue rules on aviation safety. 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.
We are issuing this rulemaking 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
rulemaking action.

Regulatory Findings

We have determined that this AD will not have federalism
implications under Executive Order 13132. This AD 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.
For the reasons discussed above, I certify that this AD:
(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.
We prepared a regulatory evaluation of the estimated costs to
comply with this AD and placed it in the AD docket. See the ADDRESSES
section for a location to examine the regulatory evaluation.

Repetitive Testing of Cargo Fire Extinguishing Bottles

(g) For all Model 767-400ER series airplanes; and the Model 777-
200 and -300 series airplanes identified in Boeing Special Attention
Service Bulletin 777-26-0033, dated December 5, 2002: Within 18
months or 6,000 flight hours after the effective date of this AD,
whichever is first, test the fill and safety fittings of the cargo
fire extinguishing bottles in the forward cargo compartment for
leaks, in accordance with the applicable service bulletin. Repeat
the test thereafter at intervals not to exceed 18 months or 6,000
flight hours, whichever is first, in accordance with the service
bulletin, until the replacement required by paragraph (h) of this AD
is accomplished.
(1) If no leak is found or if the leak rate is below the
calibrated rate specified in the service bulletin, before further
flight, apply the corrosion inhibiting compound (CIC) to the safety
disc inside the fill fitting and reidentify the cargo fire
extinguishing bottle, in accordance with the applicable service
bulletin.
(2) If any leak above the calibrated rate specified in the
service bulletin is found, before further flight, replace and
reidentify the cargo fire extinguishing bottle with new or reworked
fire extinguishing bottles, in accordance with the applicable
service bulletin; except where the service bulletin specifies that
the replacement may be accomplished according to an operator's
``equivalent procedure,'' replace in accordance with a method
approved by the Manager, Seattle Aircraft Certification Office
(ACO), FAA. Chapter 26-23-02/401 of the Boeing 767 Aircraft
Maintenance Manual (AMM) or Chapter 26-23-01/401 of the Boeing 777
AMM, as applicable, is one approved method.

Note 1: The Boeing service bulletins listed in Table 3 of this
AD refer to certain Kidde Aerospace service bulletins, as
applicable, as additional sources of service information for testing
and reidentifying the cargo fire extinguishing bottles.
