Pre-flight check of aircraft

Pre-flight check of aircraft is something that must be done prior to all flights. In the first lessons I was closely monitored by the instructor but later, I was expected to do the checks on my own and preferably prior to the lesson.

First of all I need to check that the aircraft is airworthy by checking when it was last flown and that there is no remarks the last flights. In the aircraft maintenance documents, I check that there is still available flying hours before the next service.

In the cockpit I turn on the landing light, strobe and nav lights to check that they are all working. Full flaps is set for outside flaps inspection.

On all flaps and ailerons on the wings I check that all bolts are in place and has not loosened or is damaged.

Also the bolt holding the stabilizer on the back of the aircraft is essential and must be tight and undamaged. Loosing this bolt is something no pilots ever want to experience!

Wing surface is checked for damages both on top and bottom. The stall warning mechanism is checked.

Nav lights are undamaged.

Fuel check on both left and right tank. In case of low fuel level, the aircraft must be refueled before flying. Fuel samples are taken from bottom of both tanks and from the fuel pump and checked for condensed water in the fuel tanks.

The main landing gear cover is checked for cracks and damages, and the oleo-cylinder is checked for leaking oil.

Behind the propeller the strop from the engine to the propeller should be tight.

The oleo-cylinder of the nose landing gear can be checked by pulling down in the propeller. Also here the gear is checked for no cover cracks and no oil leaks.

The engine is checked for leaks and signs of fire. Oil level is checked – minimum 4-5 quantities (out of 8).

This is done from both sides and also it is checked that no animals (like birds) has taken rest in the engine.

Brake fluid is checked.

The stabilizer is checked for backlash and damages.

The elevator trims are kept in place by these hinges so I check that these are in place.

 

If the aircraft passes all checks, it is ready to fly! If not it means a disappointing cancellation of the lesson.
