FAA just released an airworthiness directive to prevent fuel leaking into Boeing 757 engines. This AD is prompted by reports of drain holes and unsealed panels in the leading edge that are too close to the engines. The AD requires "changing the lower fixed leading edge panel assemblies immediately outboard of the nacelles at slats 4 and 7."
The AD affects 697 Boeing 757s registered in the U.S. FAA thinks it will take nine work hours to comply with the AD, so at an average labor rate of $85, this means it will cost $765 per aircraft.
The AD (2010-23-13
) takes effect Dec. 14.
