## The airworthiness directive

Compliance required within 10 hours' time in service after the effective date of this AD, unless already accomplished.

To prevent a possible restriction of the cyclic control system, accomplish the following one-time inspection and lever assembly replacement, as necessary:

a. Remove the co-pilot's seat, P/N 206-031-141, to expose the cyclic control lever assembly.

b. Inspect the control bearings in each end of the lever assembly, P/N 206-001-339- 1, for proper staking, as specified in Items 2, 3 and 4 of Bell Helicopter Company Service Bulletin No. 206A-13, dated August 4, 1969, or by a method approved by the Chief, Engineering and Manufacturing Branch, Flight Standards Division, Southwest Region, FAA.

c. Remove and replace lever assemblies that have improper stakedcontrol bearings before further flight.
