Plain English Summary

2/10 complexity

The Civil Aviation Safety Authority requires specified Aerospatiale (Socata) TB20 aeroplanes (S/No 275–700, with listed exclusions) to have their aileron balance weight attachment inspected and treated per Socata Technical/Service Bulletin No. 28 at the next Maintenance Release after 7 May 1987 and at every subsequent Maintenance Release until the aircraft is modified to remove the requirement.

This affects owners/operators and authorised maintenance organisations, who bear the inspection/repair costs; the AD responds to manufacturer reports of loosening balance weights and skin cracking.
