Plain English Summary

3/10 complexity

Owners/operators of certain Socata TB20 and TB21 aeroplanes with tilting front seats must strengthen the front seat structure by completing the manufacturer’s Service Bulletin (Socata TB SB 10‑075‑25 Amendment 1). If not already done, the work is mandatory within 50 hours TIS after 8 December 1994 or at the next maintenance release, whichever comes first. Owners bear costs; the amendment clarifies affected serials and the weld filler material to use.
