Airworthiness Directive · Amendment 39-19801 · Landing gear
The Boeing Company Airplanes
This AD applies to The Boeing Company Model 787-8, 787-9, and 787-10 airplanes, certificated in any category, as identified in Boeing Requirements Bulletin B787-81205-SB320040-00 RB, Issue 001, dated March 12, 2019.
The FAA is adopting a new airworthiness directive (AD) for certain The Boeing Company Model 787-8, 787-9, and 787-10 airplanes. This AD was prompted by reports that the nose landing gear (NLG) retracted on the ground, with weight on the airplane's wheels, due to the incorrect installation of an NLG downlock pin in the apex pin inner bore of the NLG lock link assembly. This AD requires installing an insert to prevent installation of the pin in the incorrect location. The FAA is issuing this AD to address the unsafe condition on these products.
Except as specified by paragraph (h) of this AD: At the applicable times specified in the “Compliance” paragraph of Boeing Requirements Bulletin B787-81205-SB320040-00 RB, Issue 001, dated March 12, 2019, do all applicable actions identified in, and in accordance with, the Accomplishment Instructions of Boeing Requirements Bulletin B787-81205-SB320040-00 RB, Issue 001, dated March 12, 2019.
Note 1 to paragraph (g): Guidance for accomplishing the actions required by this AD can be found in Boeing Service Bulletin B787-81205-SB320040-00, Issue 001, dated March 12, 2019, which is referred to in Boeing Requirements Bulletin B787-81205-SB320040-00 RB, Issue 001, dated March 12, 2019.
For purposes of determining compliance with the requirements of this AD: Where Boeing Requirements Bulletin B787-81205-SB320040-00 RB, Issue 001, dated March 12, 2019, uses the phrase “the Issue 001 date of Requirements Bulletin B787-81205-SB320040-00 RB,” this AD requires using “the effective date of this AD.”
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.
