Plain English Summary

2/10 complexity

This directive requires owners/operators of Aerospatiale (Socata) TB10 serials 1–239 to incorporate a Rallye TB Service Bulletin modification and update the flight manual before certification. It reduces maximum flap deflection to 25°30' and sets the forward C.G. limit to 11% M.A.C. (0.949 m) to preserve longitudinal stability with full flaps. Compliance costs (modification, manuals, tests) fall to the aircraft owner/operator or certifying authority.
