Fuel free of water and contamination
● NOTE ●
In case of water in fuel system, drain it carefully using the four drain valves of
tank sumps, and the fuel filter drain valve, till every trace of water or deposit has
disappeared.
A long term storage of the airplane causes water accumulation in fuel, which
absorbs additive. This phenomenon occurs when an excessive quantity of
water accumulates in fuel tank sumps. Refer to section 8 for servicing
operations relative to fuel additives.

● NOTE ●
If airplane has been used from muddy airfields or in snow, check wheel wells to
make sure they are clean and not obstructed.
Check frequently all landing gear retraction mechanism components,
shock-absorbers, tires and brakes. This is particularly important for airplanes
used from hilly fields.
Improperly serviced or worn shock-absorbers may result in excessive loads
being transmitted to the airplane structure during ground operations. Without
passengers and baggages on board, the unpainted surface of the main gear
shock absorber tube must be visible about :
55 mm (2.17 in) of minimum height with half tank,
40 mm (1.57 in) of minimum height with full tanks.
