Airworthiness Directive · Amendment 39-18545 · Landing gear
The Boeing Company Airplanes
This AD applies to all The Boeing Company Model 787 airplanes, certificated in any category.
We are adopting a new airworthiness directive (AD) for all The Boeing Company Model 787 airplanes. This AD was prompted by the disclosure that the inner diameters of some batches of landing gear pins were not shot peened in accordance with design specifications, and need to be replaced. This AD requires inspection for improperly manufactured landing gear pins, and replacement if necessary. We are issuing this AD to detect and correct insufficient shot peening that could lead to stress corrosion cracking and failure of the landing gear pin, and cause landing gear collapse and inability to control the airplane at high speeds on the ground.
For airplanes on which the original airworthiness certificate or the original export certificate of airworthiness was issued on or before the effective date of this AD: At the applicable time specified in paragraph 5, “Compliance,” of Boeing Alert Service Bulletin B787-81205-SB320022-00, Issue 002, dated April 6, 2016, do a landing gear pin part number and serial number inspection, in accordance with the Accomplishment Instructions of Boeing Alert Service Bulletin B787-81205-SB320022-00, Issue 002, dated April 6, 2016. A review of airplane maintenance or delivery records is acceptable in lieu of this inspection if the part number and serial number of the installed landing gear pins can be conclusively determined from that review.
(1) If the part number and serial number do not match the list of affected pin numbers: No further action is required by this paragraph at that pin location.
(2) If the part number and serial number match the list of affected pin numbers: At the applicable time specified in paragraph 5, “Compliance,” of Boeing Alert Service Bulletin B787-81205-SB320022-00, Issue 002, dated April 6, 2016, replace the affected pin with a pin that does not have an affected part number and serial number, in accordance with the Accomplishment Instructions of Boeing Alert Service Bulletin B787-81205-SB320022-00, Issue 002, dated April 6, 2016.
