FAA Part 107 Remote Pilot (UAG)OperationsEasy
A remote pilot in command is performing a preflight inspection of a sUAS before a mapping mission. They notice a minor crack in one of the propeller blades. What is the appropriate action the remote pilot should take?
- AApply tape to the crack for a temporary repair and proceed with the flight.
- BReduce the sUAS's payload to compensate for the damaged propeller.
- CReplace the damaged propeller blade before commencing the flight.
- DProceed with the flight, but monitor the propeller closely during operation.
Show answer & explanationAnswer & explanation
Correct answer: C. Replace the damaged propeller blade before commencing the flight.
Damaged propellers can lead to catastrophic failure, loss of control, and instability. Any damage to critical flight components like propellers must be addressed before flight. The appropriate action is to replace the damaged propeller with a new, undamaged one.
Why the other options are wrong
- A. Taping a propeller is not an acceptable repair for flight safety and could worsen the issue.
- B. Reducing payload does not mitigate the risk of a failing propeller and could still lead to an accident.
- D. Operating with a damaged propeller is unsafe and could lead to failure.
sUAS Preflight Inspection
A thorough preflight inspection of a sUAS is critical to identify any defects or damage that could affect safe operation prior to flight.
- Inspect all components, especially propellers, motors, battery, and airframe.
- Any detected damage affecting airworthiness must be rectified before flight.
- Ensures the sUAS is in a condition for safe operation.
