Airworthiness Directive · Amendment 39-16887 · Instruments
The Boeing Company Airplanes
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.
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.
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.”
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.
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 applicable service information specified in paragraph (i)(1) or (i)(2) of this AD. Accomplishment of the applicable requirements of paragraphs (i) and (j) of this AD terminates the requirements of paragraph (g) of this AD, provided that those actions have been accomplished on all airplanes operated within an operator's fleet.
