METHOD OF COMPLIANCE: Comply with inspection of the cyclic control lever assy's IAW AD-2009-07-52.

REASON: This Emergency Airworthiness Directive (AD) is prompted by a Transport Canada AD report of a bearing incorrectly installed in the copilot cyclic control lever assy. Investigation revealed that, although the inspection witness marks were applied on the bearing, it had not been staked during manufacture. This condition, if not detected, could result in failure of a bearing, failure of a cyclic control lever assy, and subsequent loss of control of the helicopter.

REASON: Bell's investigation of a model 206L-1 accident last year revealed that a main rotor blade fractured as a result of fatigue. The investigation established that a fatigue crack could occur if there was a combination of both residual stress in the spar and a larger than acceptable void in the adhesive applied between the blade's intertia weight and the spar, between blade stations 100 and 145. If such a condition exists, a fatigue crack may be induced by the centrifugal force variation that occurs during the helicopter start/stop cycles.
