| Pre-Flight Inspection description |
The Pre Flight walk-around is part of the first stages of any flight. As well as making sure that you are safe to fly, it is important to make sure the aircraft is also safe to fly. This page will give hints and tips about the different parts of the walk-around that are often looked over or not much thought is put into them.
An external check should normally be conducted only after the Aircraft Technical Log is available at the aircraft and has been properly examined by the aircraft commander. However, in practice on commercial airline service, the time available before departure is tight so the crew member carrying out the external check will often commence the External Check immediately on arrival at the aircraft prior to boarding. This will require good communication on eventual arrival on the flight deck regarding any issues from the Aircraft Maintenance Log and what has been seen outside the aircraft.
**Example of walk-around check:
Many things are checked on a walkaround. The pilot-in-command should do the walkaround, not the co-pilot. The main classes of items are as follows:
*structural integrity:the aircraft must be sound and undamaged and ready to fly
*sensors: sensors such as antennas and gauges should be undamaged and not have anything blocking them or adhering to them
*clean flight surfaces: the control surfaces and flight surfaces must be smooth and clean; for example, the wings must not have ice on them
*no leaks: hydraulic fluid, oil, fuel, and other critical liquids should not be leaking out of the aircraft
*chocks, control locks and covers removed: all chocks, protective coverings and locks should be removed before flight and stowed
*correct tire INFLATION wear on the tires should not be excessive and the tires should be inflated properly
*fasteners present and correct all bolts, shims, nuts and other fasteners should be present, undamaged, and correctly installed
*hatches and fairings secure: removable inspection plates and any other small doors, fairings and cowlings should be in place and secure.
*lights ok: the lights on the aircraft should operate correctly and their lenses should have no cracks or other defects
*Blades ok: the propeller or turbine blades (as the case may be) should be perfect with no cracks or chips
Overlooking any of these sorts of items can cause (and has caused) serious accidents or incidents in flight or during takeoff and landing.
