Airworthiness Directive · Amendment 39-19335 · Engine exhaust system
The Boeing Company Airplanes
This AD applies to The Boeing Company Model 787 series airplanes, certificated in any category, powered by Rolls Royce Trent 1000 engines.
We are adopting a new airworthiness directive (AD) for The Boeing Company Model 787 series airplanes powered by Rolls Royce Trent 1000 engines. This AD was prompted by a report of failures of the inner fixed structure (IFS) forward upper fire seal and damage to thermal insulation blankets in the forward upper area of the thrust reverser (TR). This AD requires an inspection to determine the part number of the IFS forward upper fire seal, and applicable on-condition actions. We are issuing this AD to address the unsafe condition on these products.
For Model 787-8 and 787-9 series airplanes identified in Boeing Alert Service Bulletin B787-81205-SB780033-00, Issue 001, dated November 1, 2017 (“BASB B787-81205-SB780033-00, Issue 001”): Within 36 months after the effective date of this AD, do all applicable actions identified as “RC” (required for compliance) in, and in accordance with, the Accomplishment Instructions of BASB B787-81205-SB780033-00, Issue 001.
