69-16-02 BELL: Amdt. 39-812. Applies to Bell Model 206A Helicopters with wire drive P/N 30000649 installed in control system hydraulic actuators P/N 41103750, P/N 41103750-2 or P/N 41103650-005.
Compliance required as follows after the effective date of this AD unless already accomplished:
1. For helicopters with 850 hours or more of hydraulic actuator time, compliance is required within the next 25 hours of flight time.
2. For helicopters with less than 850 hours of hydraulic actuator operating time, compliance is required when 875 hours of hydraulic actuator time has been attained.
To prevent hazardous forces in the control system resulting from failure of the spool valve wire drive, accomplish the following:
Remove all cyclic, collective and directional hydraulic actuators P/N 41103750, 41103750-2, and 41103650-005 and replace with hydraulic research and manufacturing hydraulic actuators P/N 41103750-003 (cyclic and collective) and 41103650-007 (directional).
(Bell Helicopter Company Service Bulletin No. 206A 12, dated 7/25/69, pertains to this matter.)
This amendment becomes effective on August 6, 1969.
