Key Hazards
- Undetected damage being carried into the next flight
- Hot motors or batteries causing burns or fire
- Cracked propellers failing during future operation
- Moisture, dust, or debris damaging moving and electrical parts
- Incomplete flight and maintenance records
- Damaged equipment being returned to service without review
2–3 Minute Talk Script
A drone operation is not complete when the aircraft lands. Postflight inspection helps identify damage, overheating, contamination, and performance problems before they affect the next mission.
The aircraft should be powered down and handled carefully after flight. Motors, batteries, and electronic components may be hot, especially after long flights, high winds, heavy payloads, or warm weather.
Propellers, arms, landing gear, camera mounts, sensors, and the airframe should be checked for cracks, looseness, deformation, or impact marks. Even a normal-looking landing can damage a component if the aircraft contacted gravel, vegetation, or debris.
Motors should be checked for unusual heat, resistance, noise, vibration, or debris. Dirt, grass, fibers, and other material should be removed only by approved methods.
Batteries should be examined for swelling, dents, punctures, damaged contacts, unusual temperature, or abnormal power use. Suspect batteries should be isolated rather than placed back into the normal charging and storage system.
Moisture, dust, mud, chemicals, salt, and other contamination should be addressed according to manufacturer instructions. Improper cleaning can damage sensors, coatings, motors, or electrical components.
Flight time, battery use, warnings, hard landings, repairs, and unusual behavior should be recorded. Maintenance records help crews identify repeated problems and retire components before failure.
Any unresolved discrepancy should remove the aircraft or component from service until a qualified person completes the required inspection or repair.
Safety Reminders
- Allow hot motors and batteries to cool safely.
- Inspect propellers, arms, landing gear, mounts, and the airframe.
- Check motors for debris, heat, noise, and resistance.
- Examine batteries for damage and abnormal power use.
- Clean contamination only with approved methods.
- Record warnings, hard landings, flight time, and maintenance needs.
- Keep damaged or questionable equipment out of service.
Ask the Crew
- Did the aircraft experience a hard landing, impact, or warning?
- Are any motors, batteries, or components unusually hot?
- Do propellers or structural parts show damage or looseness?
- What information must be entered into the flight or maintenance record?
- Which items must be isolated before the next operation?
