AD/ECUREUIL/130 - Rotor Flight Control - Collective Lever Recess

This Airworthiness Directive requires owners/operators of Eurocopter AS350 B, B1 and D helicopters (those built before MOD 071995) to modify the collective-lever recess per Eurocopter Alert Service Bulletin No. 67.00.16 Rev 2 (or later approved) and prohibits installing cover P/N 350A27-1385-20. It addresses an incident where a foreign object entered the collective recess and jammed the lever, creating a risk of loss of collective pitch control and loss of helicopter control.
