## Summary

We are revising an earlier proposed airworthiness directive (AD) for all The Boeing Company Model 777-200, -200LR, -300, and -300ER series airplanes. That supplemental notice of proposed rulemaking (SNPRM) proposed to require revising the maintenance program to incorporate a revision to the Airworthiness Limitations Section of the maintenance planning data (MPD) document. That SNPRM was prompted by reports of two in-service occurrences on Model 737-400 airplanes of total loss of boost pump pressure of the fuel feed system, followed by loss of fuel system suction feed capability on one engine, and in-flight shutdown of the engine. This action revises that SNPRM by adding Model 777F series airplanes to the applicability. We are proposing this AD to detect and correct failure of the engine fuel suction feed of the fuel system, which, in the event of total loss of the fuel boost pumps, could result in dual engine flameout, inability to restart the engines, and consequent forced landing of the airplane. Since this action imposes an additional burden over that proposed in the previous SNPRM, we are reopening the comment period to allow the public the chance to comment on this proposed change.
