To prevent inflight loss of the jet pipe or restricted fuel drainage through the jet pipe retention assemblies, with resultant fire or heat damage to the nacelle and wing, accomplish the following:
A. Within the next 60 days after the effective date of this AD, perform an inspection to ensure correct installation of the three retaining plate assemblies, which secure the jet pipe inside the jet pipe manifold, in accordance with British Aerospace Service Bulletin 78/9, Revision 1, dated September 1985. Any discrepancies found must be corrected prior to further flight.
B. Repeat the inspection required by paragraph A. above, any time the jet pipe is replaced.
C. An alternate means of compliance or adjustment of the compliance time, which provides an acceptable level of safety, may be used when approved by the Manager, Standardization Branch, ANM-113, FAA, Northwest Mountain Region.
D. Special flight permits may be issued in accordance with FAR 21.197 and 21.199 to operate airplanes to a base for the accomplishment of inspections and/or modifications required by this AD.
All persons affected by this proposal who have not already received the appropriate service documents from the manufacturer may obtain copies upon request to British Aerospace, Librarian for Service Bulletins, P.O. Box 17414, Dulles International Airport, Washington, D.C. 20041. These documents may be examined at the FAA, Northwest Mountain Region, 17900 Pacific Highway South, Seattle, Washington, or at the Seattle Aircraft Certification Office, 9010 East Marginal Way South, Seattle, Washington.

2010-23-15: We are adopting a new airworthiness directive (AD) for certain Model 777-200, -200LR, -300, and -300ER series airplanes. This AD requires removing and repairing the sealant at the four lower corners of the wing center section and the four lower t-chord segment gaps on each side of the wing center section. This AD results from reports of fuel leakage from the center tank. We are issuing this AD to detect and correct improperly applied sealant, which could result in the disbonding and displacing of sealant, and consequent fuel leaks. On the ground, uncontained fuel leakage could result in pooling, and pooling combined with an ignition source could result in a fire.

96-18-05 R1: This amendment revises an existing airworthiness directive (AD) for Bell Helicopter Textron Canada (BHTC) Model 206L, 206L-1, and 206L-3 helicopters with a certain part numbered tailboom installed, that currently requires a visual inspection of the tailboom skin in the areas around the nutplates and in the areas of the tailboom drive shaft cover retention clips for cracks and corrosion using a 10-power or higher magnifying glass until the tailboom is replaced with an airworthy tailboom. This action requires the same actions as the existing AD, but allows a longer interval for the repetitive inspections if the tailboom is modified to increase its structural integrity. Replacement with an airworthy tailboom other than a part- numbered tailboom affected by this amendment constitutes a terminating action for the requirements of this AD. This amendment is prompted by an accident and several reports of fatigue cracks in the tailboom skin in the areas around the nutplates for the tail rotor fairing and in the areas of the tail rotor drive shaft cover retention clips. The actions required by this AD are intended to prevent failure of the tailboom and subsequent loss of control of the helicopter.

2010-23-13: We are adopting a new airworthiness directive (AD) for all Model 757 airplanes. This AD requires changing the lower fixed leading edge panel assemblies immediately outboard of the nacelles at slats 4 and 7. This AD results from reports of Model 757 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 issuing this AD to prevent fuel leaking onto an engine and a consequent fire.
