Abstract
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.
