Airworthiness Directives; the Boeing Company Airplanes
The FAA withdraws a notice of proposed rulemaking (NPRM) that proposed to revise Airworthiness Directive (AD) 2012-12-15, which applies to all The Boeing Company Model 757 airplanes. The NPRM would have corrected errors in certain paragraph references in AD 2012-12-15; continued to require revising the maintenance program by incorporating new and revised fuel tank system limitations in the Airworthiness Limitations (AWLs) section of the Instructions for Continued Airworthiness; and continued to require the initial inspection of certain repetitive AWL inspections to phase-in those inspections, and repair if necessary. Since the proposed AD was issued, we have received new data that the unsafe condition has been addressed by AD 2012-12-15, and the compliance relief that would have been provided by the proposed AD is no longer relevant. Accordingly, the proposed AD is withdrawn.
Airworthiness Directives; GA 8 Airvan (Pty) Ltd Airplanes
We propose to adopt a new airworthiness directive (AD) for GA 8 Airvan (Pty) Ltd Model GA8-TC320 airplanes. This proposed AD results from mandatory continuing airworthiness information (MCAI) originated by an aviation authority of another country to identify and correct an unsafe condition on an aviation product. The MCAI describes the unsafe condition as missing required engine mount fire seal washers, which could reduce the engine retention capability in the event of a fire. We are issuing this proposed AD to require actions to address the unsafe condition on these products.
