ACTION: Notice of proposed rulemaking (NPRM). SUMMARY: The FAA proposes to adopt a new airworthiness directive (AD) for certain Ontic Engineering and Manufacturing, Inc. Model SA226-T, SA226-AT, SA226-T(B), SA226-TC, SA227-AC (C-26A), SA227-AT, SA227-BC (C-26A), SA227-CC, SA227-DC (C-26B), and SA-227-TT (300) airplanes. This proposed AD was prompted by reports of in-flight pitch trim actuator failures. This proposed AD would require repetitively inspecting the pitch trim actuator for cracked, missing, or compromised sealant, replacing and sealing the pitch trim actuator if cracked, missing, or compromised, repetitively measuring the pitch trim actuator travel time, and depending on the results of the measurements, replacing and sealing the pitch trim actuator. This proposed AD would prohibit the installation of certain pitch trim actuators unless the pitch trim actuator is sealed. The FAA is proposing this AD to address the unsafe condition on these products. DATES: The FAA must receive comments on this proposed AD by May 18, 2026.
