Failure of the Simmonds-Precision pitch trim actuator due to rod slippage or excessive freeplay, which could result in horizontal stabilizer nose-down movement or jamming.
AI-generated summary from the source AD text. Verify against the official source before acting.
Required Actions
Reduce the initial inspection interval to less than 5,000 hours time-in-service. Shorten the repetitive inspection intervals and compliance time for actuator replacement unless the actuator is new or nut tube assemblies are replaced during overhaul. Continue requirements to inspect freeplay, replace actuators if limitations not met or slippage evident, and eventually replace actuators regardless of inspection results.
