Aircraft Maintenance Operational and Functional Checks (TP 2228E-33)
The following are reminders for aircraft maintenance engineers (AME) prior to performing aircraft operational or functional checks. These do not, and are not meant to, replace a TC/FAA-approved aircraft flight manual, or the aircraft’s pilot operating handbook (POH) operation checklist. Prepared by System Safety, Atlantic Region.
Before the task:
- Confirm inspection sheets/package are completed and appropriately signed off.
- Check records/worksheets for any special attention required during aircraft operation.
- Confirm personnel are trained, current and appropriately endorsed on type.
- Be familiar with airport operator’s policies, procedures/practices, aprons, signage, runways, and designated ground-run areas.
- Take along a copy of the aerodrome diagram for reference [from Canada Airport Charts on the NAV CANADA Web site, or from the Canada Air Pilot (CAP)].
- Always refer to the aircraft’s POH operation checklist. Never rely on memory.
- Conduct a walk around of the aircraft and area for foreign object damage (FOD), loose items, control locks, inlet plugs, covers, chocks, tow-bars and tie downs.
- Check for personnel or parked aircraft nearby. Reposition the aircraft to prevent damage or injuries.
- Verify that the nose gear torque links attachment is secure.
- Verify all the aircraft fluid levels. Take fuel samples, as appropriate.
- Ensure all panels and engine cowlings are in place and secured, as required for engine operation.
- Check that all breakers and fuses are set.
- Place a fire extinguisher nearby, and have trained personnel on visual watch, as required.
- Be familiar with the location of on-board fire extinguishers.
- Verify brake operation.
- Be familiar with the aircraft communication equipment, frequencies, and radio licence requirements.
- Always carry a reliable flashlight when doing functional checks at night.
- Be familiar with the aircraft emergency procedure checklist.
During operation and taxiing:
- Always maintain communication with ground or apron controller, and report intentions before moving.
- Position aircraft into the wind for optimized engine cooling.
- Consistently monitor engine parameters from left to right and top to bottom for irregularities.
- Always remain within the aircraft operating limitations.
- Maintain professionalism in the cockpit.
- Do not RUSH!
- Keep taxi speeds to a minimum.
- While taxiing, keep hands and feet on controls at all times.
- Be prepared to shut down the engines.
Secure the aircraft:
- Again, refer to the aircraft’s POH operation checklist. Never rely on memory.
- Follow the recommended engine cool down period.
- Ensure all switches are turned off, and breakers are checked.
- Visually check fluid levels and surrounding areas for fluid leaks.
- Properly secure the aircraft.
