Plain English Summary

3/10 complexity

This directive forces owners/operators of specified Aerospatiale (Socata) TB20/TB21 aircraft (S/Ns 275–1119, except 1109) to carry out initial and recurring inspections of the landing‑gear articulated stays, following the DGAC AD and Socata SB 45 Rev 2, to prevent gear jamming.

Inspections recur every 500 flight hours or 1 year until a terminating modification (kits 9165/9166 per SB 45/1 or SB 45/2) is fitted; operators bear all costs and must track hours/calendar and follow the referenced foreign technical documents.
