## Summary

We propose to adopt a new airworthiness directive (AD) for certain M7 Aerospace LLC Models 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 SA227-TT airplanes. This proposed AD was prompted by detachment of the power lever linkage to the TPE331 engine propeller pitch control. This proposed AD would require installing a secondary retention device and repetitively inspecting the propeller pitch control for proper torque, with corrections as necessary. We are proposing this AD to correct the unsafe condition on these products.
