Summary
Special Airworthiness Information Bulletin SAIB: CE-12-16 is an FAA informational bulletin addressing elevator trim tab control system issues on Cessna Model 510 airplanes. It alerts operators to reports of pitch trim freezing in flight and provides guidance to reduce the likelihood of this problem. The bulletin references specific Cessna service letters aimed at improving drainage and sealing in the tailcone and vertical stabilizer areas.
What changed
SAIB CE-12-16 introduces awareness of pitch trim freezing incidents and recommends inspections and maintenance actions including the installation of drain holes and sealant as per Cessna Service Letters 510-53-03 and 510-55-02. It also highlights the need for regular functional checks of the autopilot servo mount to prevent torque loss due to lubricant contamination.
Why it matters
This bulletin is important for aviation professionals because pitch trim freezing can affect flight safety and aircraft controllability. Operators and maintenance personnel need to be aware of the issue to ensure proper preventive maintenance and to follow abnormal procedures if pitch trim problems occur. Compliance with the recommended inspections and maintenance helps maintain aircraft airworthiness and operational reliability.
