Airworthiness Directive · Amendment 39-18890 · Wings
The Boeing Company Airplanes
This AD applies to The Boeing Company Model 787-8 and 787-9 airplanes, certificated in any category, as identified in Boeing Alert Service Bulletin B787-81205-SB570029-00, Issue 001, dated February 23, 2016.
We are adopting a new airworthiness directive (AD) for certain The Boeing Company Model 787-8 and 787-9 airplanes. This AD was prompted by a report indicating that a portion of the sealant above the engine pylon between the wing skin and the vapor barrier might have been omitted. This AD requires an inspection for missing sealant in the seam on the outside and inside of the engine struts, and corrective actions if necessary. We are issuing this AD to address the unsafe condition on these products.
Within 60 months after the effective date of this AD: Do a general visual inspection for missing sealant in the seam on the outside and inside of the engine struts, in accordance with the Accomplishment Instructions of Boeing Alert Service Bulletin B787-81205-SB570029-00, Issue 001, dated February 23, 2016. Do all applicable corrective actions before further flight, in accordance with the Accomplishment Instructions of Boeing Alert Service Bulletin B787-81205-SB570029-00, Issue 001, dated February 23, 2016.
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.
