Boeing 737 HSTA Record Review Required
The FAA proposes a new airworthiness directive for Boeing Model 737-600, -700, -700C, -800, -900, and -900ER airplanes after reports of under-torqued and missing nuts on the horizontal stabilizer trim actuator (HSTA) lower gimbal assembly. The proposed AD would require review of maintenance records to determine if an overhauled HSTA was inspected and if corrective actions were accomplished using specified service information, and would require applicable on-condition actions to address the unsafe condition.
