Airworthiness Directives; The Boeing Company Airplanes

Publication summary

We are superseding an existing airworthiness directive (AD) for all The Boeing Company 757-200, 757-200PF, 757-200CB, 757-300, 767- 200, 767-300, and 767-300F series airplanes. That AD currently requires revising the Limitations section of the airplane flight manual (AFM) to advise the flightcrew of procedures to follow to ensure that a fuel filter impending bypass condition due to gross fuel contamination is detected in a timely manner. This new AD requires installing new operating program software (OPS) (Version 7) of the engine indication and crew alerting system (EICAS) in the EICAS computers. This AD also requires various concurrent actions. This AD also retains the existing AD provision that relieves certain airplanes (those equipped with certain EICAS OPS versions) from the requirements. Accomplishment of the new actions terminates the requirements of the existing AD. This AD was prompted by an error in the EICAS OPS. The error prevents the display of an advisory message to the flightcrew 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 correct the unsafe condition on these products.

Unsafe Condition
(e) Unsafe Condition

    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 flightcrew 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.

Revision of Airplane Flight Manual (AFM)
(g) Revision of Airplane Flight Manual (AFM)

    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, 
Amendment 39-15488 (73 FR 21811, April 23, 2008)), 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.''

14 CFR Part 39

[Docket No. FAA-2011-0382; Directorate Identifier 2010-NM-063-AD; 
Amendment 39-16887; AD 2011-25-11]
RIN 2120-AA64


Airworthiness Directives; The Boeing Company Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Final rule.

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

SUMMARY: We are superseding an existing airworthiness directive (AD) 
for all The Boeing Company 757-200, 757-200PF, 757-200CB, 757-300, 767-
200, 767-300, and 767-300F series airplanes. That AD currently requires 
revising the Limitations section of the airplane flight manual (AFM) to 
advise the flightcrew of procedures to follow to ensure that a fuel 
filter impending bypass condition due to gross fuel contamination is 
detected in a timely manner. This new AD requires installing new 
operating program software (OPS) (Version 7) of the engine indication 
and crew alerting system (EICAS) in the EICAS computers. This AD also 
requires various concurrent actions. This AD also retains the existing 
AD provision that relieves certain airplanes (those equipped with 
certain EICAS OPS versions) from the requirements. Accomplishment of 
the new actions terminates the requirements of the existing AD. This AD 
was prompted by an error in the EICAS OPS. The error prevents the 
display of an advisory message to the flightcrew 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 correct the unsafe 
condition on these products.

DATES: This AD is effective January 17, 2012.
    The Director of the Federal Register approved the incorporation by 
reference of certain publications listed in the AD as of January 17, 
2012.

SUPPLEMENTARY INFORMATION: 

Discussion

    We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR 
part 39 to supersede AD 2008-09-07, Amendment 39-15488 (73 FR 21811, 
April 23, 2008). That AD applies to the specified products. The NPRM 
was published in the Federal Register on April 20, 2011 (76 FR 22059). 
That NPRM proposed to require installing new EICAS OPS (Version 7) in 
the EICAS computers. That NPRM also proposed to 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. That NPRM also 
proposed to retain the existing AD provision that relieves certain 
airplanes (those equipped with certain EICAS OPS versions) from the 
proposed requirements. That NPRM also specified that accomplishment of 
the new proposed actions would terminate the requirements of the 
existing AD.

Comments

    We gave the public the opportunity to participate in developing 
this AD. The following presents the comments

[[Page 77372]]

received on the proposal and the FAA's response to each comment.

Support for NPRM

    Boeing and Air Line Pilots Association, International, support the 
intent and contents of the NPRM (76 FR 22059, April 20, 2011).

Request To Remove Requirement To Install OPS Version 2

    ABX Air requested that we revise the NPRM (76 FR 22059, April 20, 
2011) to remove the requirement to install OPS Version 2 before 
installing OPS Version 7. ABX Air contended that OPS Version 2 is not a 
prerequisite to OPS Version 7, and does not need to be required in the 
AD.
    We agree with the request, for the reasons provided by the 
commenter. Where paragraph (j)(12) of the proposed AD would have 
required installing ``EICAS OPS Version 2 and EICAS OPC software, as 
applicable,'' we have limited that requirement in this final rule to 
installing ``EICAS OPC software, as applicable.''

Conclusion

    We reviewed the relevant data, considered the comments received, 
and determined that air safety and the public interest require adopting 
the AD with the change described previously. We also determined that 
this change will not increase the economic burden on any operator or 
increase the scope of the AD.

Costs of Compliance

    We estimate that this AD affects 1,078 airplanes of U.S. registry. 
We estimate the costs to comply with the following requirements:

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

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),
    (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

Adoption of the Amendment

    Accordingly, under the authority delegated to me by the 
Administrator, the FAA amends 14 CFR part 39 as follows:

PART 39--AIRWORTHINESS DIRECTIVES

0
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]

0
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:


[[Page 77373]]


2011-25-11 The Boeing Company: Amendment 39-16887; Docket No. FAA-
2011-0382; Directorate Identifier 2010-NM-063-AD.

(a) Effective Date

    This airworthiness directive (AD) is effective January 17, 2012.

(b) Affected ADs

    This AD supersedes AD 2008-09-07, Amendment 39-15488 (73 FR 
21811, April 23, 2008).

(c) Applicability

    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.

(d) Subject

    Joint Aircraft System Component (JASC)/Air Transport Association 
(ATA) of America Code 31: Instruments.

(e) Unsafe Condition

    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 flightcrew 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.

(f) Compliance

    Comply with this AD within the compliance times specified, 
unless already done.

Restatement of Requirements of AD 2008-09-07, Amendment 39-15488 (73 FR 
21811, April 23, 2008), With No Changes

(g) Revision of Airplane Flight Manual (AFM)

    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, 
Amendment 39-15488 (73 FR 21811, April 23, 2008)), 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.''

(h) Exception to AFM Limitations Requirement

    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.

New Requirements of This AD

(i) EICAS OPS Installation

    Except as provided by paragraph (k) of this AD: Within 90 days 
after the effective date of this AD, install EICAS OPS Version 7 in 
the left and right EICAS computers, in accordance with the
