Airworthiness Directives; The Boeing Company Model 757 Airplanes,
and Model 767-200, 767-300, and 767-300F Series Airplanes
AGENCY: Federal Aviation Administration (FAA), DOT.
ACTION: Notice of proposed rulemaking (NPRM).
-----------------------------------------------------------------------
SUMMARY: We propose to supersede an existing airworthiness directive
(AD) that applies to the products listed above. The existing AD
currently requires revising the Limitations section of the airplane
flight manual (AFM) to advise the flight crew of procedures to follow
to ensure that a fuel filter impending bypass condition due to gross
fuel contamination is detected in a timely manner. Since we issued that
AD, a new design change has been developed that will correct an error
in the operating program software (OPS) of the engine indication and
crew alerting system (EICAS). This proposed AD would require installing
new OPS (Version 7) of the EICAS in the EICAS computers. This proposed
AD would also require various concurrent actions, depending on the
airplane configuration, including installing a certain EICAS OPS
version, making wiring changes, replacing the audio accessory unit,
replacing certain handsets and EICAS computers, changing EICAS computer
connector keying, and loading Operational Program Configuration (OPC)
software. This proposed AD also retains the existing AD provision that
relieves certain airplanes (those equipped with certain EICAS OPS
versions) from the proposed requirements. Accomplishment of the new
proposed actions would terminate the requirements of the existing AD.
We are proposing this AD to prevent malfunction and thrust loss on both
engines, which could result in a forced off-airport landing.
DATES: We must receive comments on this proposed AD by June 6, 2011.

Discussion
On April 14, 2008, we issued AD 2008-09-07, Amendment 39-15488 (73
FR 21811, April 23, 2008), for all Boeing Model 757 airplanes and Model
767-200, 767-300, and 767-300F series airplanes. That AD requires
revising the Limitations section of the airplane flight manual (AFM) to
advise the flight crew of procedures to follow to ensure that a fuel
filter impending bypass condition due to gross fuel contamination is
detected in a timely manner. That AD was prompted by an error in
Version 6 of the operating program software (OPS) of the engine
indication and crew alerting system (EICAS). The error prevents the
display of an advisory message to the flight crew of a left engine fuel
filter contamination and imminent bypass condition, which may indicate
an imminent multiple engine thrust loss or engine malfunction event due
to fuel contamination. We issued that AD to prevent malfunction and
thrust loss on both engines, which could result in a forced off-airport
landing.
Actions Since Existing AD Was Issued
AD 2008-09-07 requires interim crew actions, via AFM limitations,
to mitigate the unsafe condition introduced by Version 6 of the OPS.
Since we issued that AD, Boeing has developed OPS Version 7, which
corrects an error in the OPS of the EICAS and will allow removal of the
required AFM limitations.
Relevant Service Information
We have reviewed Boeing Special Attention Service Bulletins 757-31-
0192 (for Model 757 airplanes) and 767-31-0267 (for Model 767-200, -
300, -300F series airplanes), both dated September 11, 2009. The
service bulletins describe procedures for installing new EICAS OPS in
the left and right EICAS computers.
Service Bulletin 757-31-0192 specifies the concurrent
accomplishment of the actions specified in Boeing Service Bulletins
757-31-0104 (for Model 757-200 series airplanes) and 757-31-0105 (for
Model 757-300 series airplanes), both dated December 5, 2002, which
describe procedures for changing the EICAS OPS.
Service Bulletin 767-31-0267 specifies the concurrent
accomplishment of the actions specified in the service bulletins
identified in the following table.

FAA's Determination
We are proposing this AD because we evaluated all the relevant
information and determined the unsafe condition described previously is
likely to exist or develop in other products of these same type
designs.
Proposed AD Requirements
This proposed AD would continue to require the AFM limitations
specified in AD 2008-09-07. This proposed AD would also require the
actions specified in the service information described previously,
which would terminate the AFM limitations. This proposed AD also
includes a provision that provides relief from the proposed
requirements for airplanes with EICAS OPS versions other than Version
6.
Change to Existing AD
This proposed AD would retain the requirements of AD 2008-09-07.
Since that AD was issued, the AD format has been revised, and certain
paragraphs have been rearranged. As a result, the corresponding
paragraph identifiers have changed in this proposed AD, as listed in
the following table:

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 proposed AD would not have federalism
implications under Executive Order 13132. This proposed AD would 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 the proposed
regulation:
(1) Is not a ``significant regulatory action'' under Executive
Order 12866,
(2) Is not a ``significant rule'' under the DOT Regulatory Policies
and Procedures (44 FR 11034, February 26, 1979),
(3) Will not affect intrastate aviation in Alaska, and
(4) 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.
List of Subjects in 14 CFR Part 39
Air transportation, Aircraft, Aviation safety, Incorporation by
reference, Safety.
The Proposed Amendment
Accordingly, under the authority delegated to me by the
Administrator, the FAA proposes to amend 14 CFR part 39 as follows:
PART 39--AIRWORTHINESS DIRECTIVES
1. The authority citation for part 39 continues to read as follows:
Authority: 49 U.S.C. 106(g), 40113, 44701.
Sec. 39.13 [Amended]
2. The FAA amends Sec. 39.13 by removing airworthiness directive
(AD) 2008-09-07, Amendment 39-15488 (73 FR 21811, April 23, 2008), and
adding the following new AD:
The Boeing Company: Docket No. FAA-2011-0382; Directorate Identifier
2010-NM-063-AD.
Comments Due Date
(a) The FAA must receive comments on this AD action by May 5,
2011.
Affected ADs
(b) This AD supersedes AD 2008-09-07, Amendment 39-15488.
Applicability
(c) This AD applies to all The Boeing Company 757-200, 757-
200PF, 757-200CB, 757-300, 767-200, 767-300, and 767-300F series
airplanes; certificated in any category.
Subject
(d) Joint Aircraft System Component (JASC)/Air Transport
Association (ATA) of America Code 31, Instruments.
Unsafe Condition
(e) This AD was prompted by an error in the operating program
software (OPS) of the engine indication and crew alerting system
(EICAS). The error prevents the display of an advisory message to
the flight crew of a left engine fuel filter contamination and
imminent bypass condition, which may indicate an imminent multiple
engine thrust loss or engine malfunction event due to fuel
contamination. We are issuing this AD to prevent malfunction and
thrust loss on both engines, which could result in a forced off-
airport landing.
Compliance
(f) Comply with this AD within the compliance times specified,
unless already done.
Restatement of Requirements of AD 2008-09-07, With No Changes
Revision of Airplane Flight Manual (AFM)
(g) Except as provided by paragraphs (h) and (i) of this AD:
Within 30 days after May 8, 2008 (the effective date of AD 2008-09-
07), revise the Limitations section of the applicable AFM to include
the following. This may be done by inserting a copy of this AD into
the AFM.
If the STATUS cue shows while on the ground after engine start
or during flight, select the status page on the secondary EICAS
display, and verify the ``L ENG FUEL FILT'' message is not shown. If
the ``L ENG FUEL FILT'' message is not shown on the status page, the
secondary engine parameters may be reselected on the secondary EICAS
display, or the display may be blanked. If the ``L ENG FUEL FILT''
message is shown on the status display, accomplish the ENGINE FUEL
FILTER non-normal checklist as published in the Boeing Quick
Reference Handbook. If on the ground, check the Dispatch Deviations
Guide (DDG), or operator equivalent.
In the event that the status level ``L ENG FUEL FILT'' and
advisory level ``R ENG FUEL FILT'' messages are simultaneously
shown, an impending fuel filter bypass condition exists on both
engines. With both messages shown, airplane fuel system
contamination may be present and may result in erratic engine
operation or flameout.
Further flight crew action in response to either or both the ``L
ENG FUEL FILT'' status-level message and the ``R ENG FUEL FILT''
advisory level messages being shown are not established by Boeing or
the FAA. Any further flight crew action should be determined by
individual operator policy.
Boeing policy on flight crew use of status-level messages has
not changed. After engine start, any condition having an adverse
effect on safe continuation of the flight appears as an EICAS alert
message (Warning, Caution, or Advisory). If other status-level
messages are shown as a consequence of complying with these
temporary operating instructions, the flight crew should respond in
accordance with the appropriate operator policy.
Dispatch of the airplane with an inoperative EICAS display unit
is prohibited.
Exception to AFM Limitations Requirement
(h) If all affected airplanes in an operator's fleet have been
verified by the operator to have EICAS computer part number
S242N701-1001 and only EICAS OPS versions other than Version 6
software that are FAA approved for that airplane, then
accomplishment of the actions specified in paragraph (g) of this AD
is not required.
[[Page 22063]]
