To prevent possible destructive aileron flutter, accomplish the following:
a) Check the permanent aircraft records of the airplane to determine if it has been modified per the applicable STC at Robertson Aircraft Corporation Repair Station No. 415-23 prior to August 1, 1983. If not, no furtheraction is necessary. If, modified at this facility before this date, inspect and, if necessary, correct the aileron balance weight installation in accordance with paragraph b) of this AD.
b) Measure the height of all aileron balance weights. If the measured height of all weights is approximately 3/4 inch, the weights are correctly installed and no further action is necessary. If the measured height of any weight is approximately 1/2 inch, prior to further flight, install new balance weights of the appropriate part number in accordance with the applicable STC data or Robertson Service Bulletin No. 20. Rebalance the ailerons within the limits specified by the Cessna Aircraft Company Service Manual for the airplane involved.
c) Airplanes may be flown in accordance with FAR 21.197 to a location where this AD may be accomplished.
d) An equivalent method of compliance with this AD may be used if approved by the Manager, Seattle Aircraft Certification Office, FAA, NorthwestMountain Region, 9010 East Marginal Way South, Seattle, Washington 98168.
