Start Preamble

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 Start Printed Page 77372received 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:

Estimated Costs

ActionLabor costParts costCost per productCost on U.S. operators
AFM revision (retained from AD 2008-09-07, Amendment 39-15488 (73 FR 21811, April 23 2008)1 work-hour × $85 per hour = $85085$91,630
EICAS OPS installation (new proposed action)1 work-hour × $85 per hour = $8508591,630

We have no definitive data for the number of U.S.-registered airplanes subject to the proposed concurrent requirements in this AD, but we provide the following estimated per-airplane costs to comply with the concurrent actions.

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.

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.
