Airworthiness Directives; The Boeing Company Model 757 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 Model?

airplanes. This proposed AD would require changing the lower fixed leading edge panel

assemblies immediately outboard of the nacelles at slats 4 and 7. This proposed AD

results from reports of757 airplanes in service that have drain holes and unsealed panel

assemblies in the fixed leading edge adjacent to the inboard end of slats 4 and 7 that are

too close to the hot portion of the engines. We are proposing Ihis AD to prevent fuel

leaking onto an engine and a consequent fire.

DATES: We must receive comments on this proposed AD by [INSERT DATE 45

DAYS AFTER DATE OF PUBLICATION IN THE FEDERAL REGISTER].

ADDRESSES: You may send comments by any of the following methods:

• Federal eRulemaking Portal: Go to http://www.regulations.gov. Follow the

instructions for submitting conunents.

• Fax: 202-493-2251.
