Airworthiness Directive · Amendment 39-21639 · Horizontal stabilizer, plate/skin
True Flight Holdings LLC Airplanes
This AD applies to True Flight Holdings LLC Models AA-1, AA-1A, AA-1B, AA-1C, and AA-5 airplanes, all serial numbers, certificated in any category.
The FAA is adopting a new airworthiness directive (AD) for all True Flight Holdings LLC Models AA-1, AA-1A, AA-1B, AA-1C, and AA-5 airplanes. This AD was prompted by the report of an accident of an airplane exhibiting bondline corrosion and delamination of the horizontal stabilizers. This AD requires inspecting the horizontal stabilizers, including the bondlines, for cracks, buckles, corrosion, delamination, rust, and previous repair and repairing or replacing parts and applying corrosion inhibitor as necessary. The FAA is issuing this AD to address the unsafe condition on these products.
Within the next 25 hours time-in-service or at the next scheduled 100 hour or annual inspection after the effective date of this AD, whichever occurs first, inspect the horizontal stabilizers, paying particular attention to the bondlines, for cracks, buckles, corrosion, delamination, rust, and previous repair in accordance with paragraphs 1. and 3. of Part B of True Flight Aerospace Service Bulletin SB-195, Revision A, dated June 1, 2021 (True Flight SB-195, Revision A). If there is any crack, buckle, corrosion, delamination, rust, or previous repair, before further flight, repair or replace the affected part in accordance with paragraphs 1.c. and 2. through 4. of True Flight SB-195, Revision A, as applicable.
True Flight SB-195, Revision A specifies notifying True Flight Holdings LLC of compliance with the service bulletin; however, this AD does not contain that requirement.
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.
