MODIFICATIONS None
REASON/DESCRIPTION/OPERATIONAL CONSEQUENCES During heavy maintenance visit on A300-600 aircraft, departed parts were reported (right hand spherical bearing and retaining parts) from Trimmable Horizontal Stabilizer (THS) Actuator ball nut trunnion lower attachment. The THS Actuator has a fail-safe design at lower attachment by a primary and secondary load path on RH and LH sides, which ensure the load path continuity between the Horizontal Tail Plane and the actuator. Only the primary load path is engaged in normal configuration thanks in particular to the spherical bearing and retaining parts.
In case the spherical bearing departs, the associated primary load path is disconnected and the associated secondary load path engaged whereas the primary load path stays operational at the other side. The secondary load path engagement remains hidden and the attachment will only withstand the loads for a limited period of time.
NOTE : The spherical bearing installation on each side is different, floating on the RH side and fixed to the Horizontal Tail Plane (HTP) arm on the LH side.
AIRBUS requests a one-time inspection to check the correct installation of the RH spherical bearing on Wide Body fleet.
The accomplishment of this Service Bulletin will contribute to ensure the reliable function of the THS Actuator.
