Unsafe Condition
Possible destructive aileron flutter due to incorrectly installed aileron balance weights with measured height of approximately 1/2 inch.
AI-generated summary from the source AD text. Verify against the official source before acting.
Required Actions
Check aircraft records to determine if modified per applicable STC before August 1, 1983. If modified, inspect and correct aileron balance weight installation by measuring weight height. If any weight is 1/2 inch, install new weights per STC data or SB No. 20 and rebalance ailerons. Use equivalent methods if approved.

Compliance: Required within the next 50 hours time-in-service after the effective date of this AD, unless already accomplished. 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 further action 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, Northwest Mountain Region, 9010 East Marginal Way South, Seattle, Washington 98168.
