7.2. Types of Operation
The table below shows all types of Operations undertaken by Leicester Drones and the aircraft used
for each operation:-
8. Maintenance Principles and Regime
Only Leicester Drones staff or appointed service engineers can carry out maintenance to DJI Phantom 3
Advanced aircraft. In all cases the Maintenance Logbook must be filled in to reflect any work completed and
a flight test which tests all functions must be carried out by a registered, qualified Leicester Drones pilot.
ROUTINE MAINTENANCE
The Pre-Flight and Post-Flight checklists as shown in Appendix D must be carried out by a Leicester Drones
pilot every time a Leicester Drones aircraft is operated.
Either every six months or every fifty hours of flight time, whichever comes first, the following inspection
should be carried out by a Leicester Drones qualified pilot. The inspection should be recorded in the Aircraft
Maintenance Logbook along with any findings. Any issues identified must be remedied and the aircraft must
undergo a full flight test before the aircraft is returned to Operational Status:-
Inspect the airframe for any damage, unusual marks and tightness of fixings.
Inspect the motor mountings for correct tension.
Inspect propellers for condition, unusual marks, chips, cracks and tightness of fixings.
Inspect electrical wiring for condition, unusual marks or discolouration.
Inspect electrical terminal fittings and plugs for secure attachment and general condition.
Inspect attachment of all fittings such as flight controller, GPS antennae etc. for secure attachment
Inspect payload attachment points for condition and security of payload.
Inspect condition and function of all ancillary equipment such as transmitter, ground station etc.
Test all system battery packs for charge status and general condition.
If any issues or problems are identified then the aircraft must not be allowed to fly until the issue has been
remedied. If Minor problems (damaged propeller, faulty battery pack etc.) are identified and remedied and
the Pilot-In-Command believes the aircraft is suitable to return to Operational Status, then the work
completed should be noted in the Aircraft Maintenance Logbook. If Major issues are identified
(unserviceable motor, damaged airframe etc.) then the aircraft must undergo a full flight test regime as
shown below once the identified fault has been remedied:-
FULL FLIGHT TEST
The system must have all functions thoroughly tested with a minimum of fifteen minutes flight time by a
qualified Leicester Drones pilot recording any abnormalities in the Aircraft Operating Hours Logbook. If the
Pilot-In-Command deems the aircraft safe then the Accountable Manager, Christian Smith should sign the
Aircraft Operating Hours Logbook as fit for operational use.
