Summary
The FAA proposes to adopt a new airworthiness directive (AD) for Bell Textron Inc. (Type Certificate previously held by Bell Helicopter Textron Inc.) (Bell), Model 204B, 205A-1, and 212 helicopters. This proposed AD was prompted by reports of corrosion on main rotor hub tension-torsion strap (TT strap) assemblies. This proposed AD would require reducing the life limit of a certain part- numbered TT strap assembly and prohibit installing this TT strap assembly on any helicopter. The FAA is proposing this AD to address the unsafe condition on these products.
