Airworthiness Directive · Amendment 39-19668 · Flight controls
The Boeing Company Airplanes
Superseded. A later AD replaced this one: AD 2025-20-04. Comply with the one in force.
This AD applies to all The Boeing Company Model 757-200, -200PF, -200CB, and -300 series airplanes, certificated in any category.
The FAA is adopting an airworthiness directive (AD) for all The Boeing Company Model 757 airplanes. This AD requires repetitive checks of the aileron trim actuator bearing for free rotation, repetitive detailed inspections of the aileron trim actuator attachment lug for damage and cracking, and applicable on-condition actions. This AD was prompted by a report of the failure of the aileron trim actuator attachment lug. 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 Alert Requirements Bulletin 757-27A0159 RB, dated March 29, 2019, do all applicable actions identified in, and in accordance with, the Accomplishment Instructions of Boeing Alert Requirements Bulletin 757-27A0159 RB, dated March 29, 2019.
Note 1 to paragraph (g): Guidance for accomplishing the actions required by this AD can be found in Boeing Alert Service Bulletin 757-27A0159, dated March 29, 2019, which is referred to in Boeing Alert Requirements Bulletin 757-27A0159 RB, dated March 29, 2019.
(1) For purposes of determining compliance with the requirements of this AD: Where Boeing Alert Requirements Bulletin 757-27A0159 RB, dated March 29, 2019, uses the phrase “the original issue date of the Requirements Bulletin 757-27A0159 RB,” this AD requires using “the effective date of this AD.”
(2) Where Boeing Alert Requirements Bulletin 757-27A0159 RB, dated March 29, 2019, specifies contacting Boeing for repair instructions: This AD requires doing the repair using a method approved in accordance with the procedures specified in paragraph (i) 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.
