Airworthiness Directive 2016-06-10
one-timeAirworthiness Directives; The Boeing Company Airplanes
What this AD requires
We are adopting a new airworthiness directive (AD) for certain The Boeing Company Model 787-8 airplanes. This AD was prompted by a report of fuel leaking onto the hot exhaust portion of an engine as a result of an unintended leak path from the leading edge through the pylon. This AD requires installing new seal dams in the inboard and outboard corners of the aft pylon frame on the left and right engines, including an inspection for damage of the outboard blade seal and applicable corrective actions. We are issuing this AD to prevent fuel leaking from an unintended drain path from the leading edge through either the left or right pylon and onto the hot engine parts or brakes, which could lead to a major ground fire.
Which aircraft AD 2016-06-10 applies to
Applies to airplanes as identified in Boeing Alert Service Bulletin B787-81205-SB540004-00, Issue 002, dated December 3, 2015.
Whether AD 2016-06-10 actually applies to your aircraft (by serial and installed parts) and whether it’s already complied with comes from that aircraft’s records.
How AD compliance is recorded
A valid compliance record (14 CFR 43.9) states:
Tailplate reads a tail number’s logbooks and matches every applicable AD — including this one — to its compliance evidence, with recurring next-due dates computed.
