Full official abstract

This amendment supersedes an existing airworthiness directive (AD), applicable to Bell Helicopter Textron, Inc. (BHTI) Model 204B, 205A, and 205A-1 helicopters, that currently requires modifying and inspecting the vertical fin spar (fin spar) for cracks. This amendment requires modification and visual and dye-penetrant inspections of the fin spar for cracks, and if a crack is discovered, replacing the fin spar. A tapping test for disbonding and replacing certain fin spars within 12 calendar months is also required. This amendment is prompted by an accident involving a Model 205A-1 helicopter and four other accidents involving helicopters of similar type design. The actions specified by this AD are intended to prevent failure of the fin spar, loss of the tail rotor, and subsequent loss of control of the helicopter.
