Airworthiness Directive · Amendment 39-8858 · The Boeing Company Airplanes
The Boeing Company Airplanes
This AD applies to The Boeing Company 737-300 Series, 737-400 Series, 737-500 Series.
The models as the FAA's AD index lists them. The serial ranges, installed parts and exceptions are in the AD itself: read it at the FAA.
This amendment adopts a new airworthiness directive (AD), applicable to certain Boeing Model 737-300, -400, and -500 series airplanes, that requires modification of the leading edge slat access panel and internal structure at Front Spar Station (FSS) 250.663. This amendment is prompted by reports that fuel leaking from the fuel line at FSS 250.663 flowed through a drain hole in a slat access panel and leaked into the turbine exhaust area. The actions specified by this AD are intended to prevent drainage from such a fuel leak into the turbine exhaust area, which could cause an external fire under the wing.
The aircraft, engines and makers this AD names, by the model designations in its text. A model listed here may still be outside the AD's serial ranges.
