## Summary

The FAA proposes to adopt a new airworthiness directive (AD) for certain DAHER AEROSPACE (DAHER) (type certificate previously held by SOCATA) Model TBM 700 airplanes. This proposed AD was prompted by reports of wear of the inner flap actuator drive nut. This proposed AD would require cleaning and lubricating the internal actuator rods, measuring the play between the drive nuts and the internal actuator rods, and if any play is found, replacing the drive nuts. This proposed AD would also allow replacing the drive nuts with certain other design drive nut as terminating action for the proposed requirements. The FAA is proposing this AD to address the unsafe condition on these products.
