PREFLIGHT INSPECTION (Cont’d)
12 -- Fuel tank drain (two on each wing) DRAIN . . . . . . . . . . . . . . . . . . .
(Fuel free of water and contamination)
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.
13 -- L.H. main landing gear
-- Shock absorber / doors /
tire / wheel well CHECK . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .
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 (140 us gal),
. 40 mm (1.57 in) of minimum height with full tanks (280 us gal).
