summary: The FAA proposes to adopt a new airworthiness directive (AD) for all Diamond
  Aircraft Industries GmbH (DAI) Model DA 50 C airplanes. This proposed AD was prompted
  by reports of flap actuator failures. This proposed AD would require inspecting
  for displacement of the black slide grommet and inspecting the rod end bearing for
  a tight fit of the flap actuator. This proposed AD would also require modification
  of the flap actuator followed by repetitive inspections for a broken actuator torque
  seal on the jam nuts at the attachment of the rod end bearing of the flap actuator
  with applicable corrective action. This proposed AD would also prohibit the installation
  of unmodified flap actuators on any airplane. The FAA is proposing this AD to address
  the unsafe condition on these products.

# Airworthiness Directives; Diamond Aircraft Industries GmbH Airplanes

## TL;DR
The FAA proposes to adopt a new airworthiness directive (AD) for all Diamond Aircraft Industries GmbH (DAI) Model DA 50 C airplanes. This proposed AD was prompted by reports of flap actuator failures. This proposed AD would require inspecting for displacement of the black slide grommet and inspecting the rod end bearing for a tight fit of the flap actuator. This proposed AD would also require modification of the flap actuator followed by repetitive inspections for a broken actuator torque seal on the jam nuts at the attachment of the rod end bearing of the flap actuator with applicable corrective action. This proposed AD would also prohibit the installation of unmodified flap actuators on any airplane. The FAA is proposing this AD to address the unsafe condition on these products.
