Note: Helicopters modified in accordance with the requirements of the original issue of this AD and found to have satisfactory clearance as required by Amdt 1 of this AD are acceptable as complying with this AD.

Background: An accident which occurred due to loss of cyclic control whilst the helicopter was being flown from the left hand (co-pilot) seat, has been associated to the quick disconnect cyclic stick being improperly installed where it attaches to the lever assembly under the co-pilot seat.

Amdt 1 was issued to eliminate part interference between the gas producer tube and a rivet attaching the spring pin assembly.

This amendment has been issued to include Agusta-Bell model AB 206A and AB 206B model helicopters.
