Plain English Summary

2/10 complexity

What this does: Bans the use of counterfeit helicopter parts—specifically fake "tension torsion straps"—on Bell 205A and 205A-1 helicopters.

Who it affects: Owners and operators of these specific Bell helicopter models.

What must be done: Before flying these helicopters after 3 November 1989, operators must follow the manufacturer's safety bulletin (BHT ASB 205-89-33 Rev A) to inspect and replace the faulty parts.

Why it matters: The straps are counterfeit aircraft parts made without proper safety approval (FAA PMA—Federal Aviation Administration Parts Manufacturer Approval). Tension torsion straps are critical components that absorb flight loads in the helicopter's rotor system; fake ones could snap in flight, causing catastrophic failure.

In simple terms: If your Bell 205 helicopter has dodgy, unapproved straps installed, you cannot fly until you've fixed the problem according to the manufacturer's instructions.
