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.
