[Docket No. FAA–2008–0618; Directorate Identifier 2007–NM–355–AD] RIN 2120–AA64
Airworthiness Directives; Boeing Model 777 Airplanes
AGENCY: Federal Aviation Administration (FAA), DOT.
ACTION: Notice of proposed rulemaking (NPRM).
SUMMARY: We propose to adopt a new airworthiness directive (AD) for all Boeing Model 777 airplanes. This proposed AD would require performing repetitive operational tests of the engine fuel suction feed of the fuel system, and other related testing if necessary. This proposed AD results from a report of inservice occurrences of loss of fuel system suction feed capability, followed by total loss of pressure of the fuel feed system. We are proposing this AD to detect and correct failure of the engine fuel suction feed of the fuel system, which could result in dual engine flameout, inability to restart the engines, and consequent forced landing of the airplane.
DATES: We must receive comments on this proposed AD by July 21, 2008.
---- END QUOTE -----
No mention of using any specific grade or type of fuel, or of testing at low temperatures, just testing.
