           and UH-1P; and Southwest Florida Aviation Model SW204, SW204HP, SW205 and SW205A-1 helicopters, manufactured by Bell Helicopter Textron Inc. (BHTI) for the armed forces of the United States, with main rotor tension-torsion (TT) strap, part number 204-012-122-1, 204-012-122-5, 2601399, or 2606650, installed.

           Requirement: Remove and replace any TT strap with 1,200 hours total time in service or 24 months since the initial installation, whichever occurs first.

           Note: FAA AD 2002-20-01 Amdt 39-12895 refers.

 Compliance: Before further flight after 30 October 2002.

           This Airworthiness Directive becomes effective on 30 October 2002.

           Background: This Directive is prompted by the FAA requirement to update the product identification, extend the application to other models, continuing the existing retirement time for certain main rotor TT straps, and adding TT strap part numbers to the applicability. The actions required by this Directive are intended to prevent failure of a TT strap, loss of a main rotor blade, and subsequent loss of control of the helicopter.
