Repairs or Modifications: How should the work be handled?

• A. All work should be documented in a maintenance log and followed by a full system functional flight check.
• B. Repairs may be informal and need no check if no faults found.
• C. Modifications should be avoided but if done no check is needed.
• D. Documentation is unnecessary if the work is minor.

Answer: (A)

Repairs or modifications must be documented and followed by a full system functional flight check. Keeping a maintenance log records what was done, when it was done, who performed the work, and any parts replaced, which is essential for safety, traceability, and regulatory compliance. After work is completed, a comprehensive flight check tests all critical systems—propulsion, flight controls, sensors, GPS/compass, failsafes, and power systems—to confirm the aircraft still operates correctly and safely. If any issue is found, the problem should be addressed and re-tested until the vehicle passes. Skipping documentation or skipping the flight check leaves hidden faults or improper modifications unchecked, which can compromise safety. Minor work still requires proper records and verification to ensure airworthiness before the next flight.
