The pre-flight inspection starts on the left side of the cockpit and proceeds clockwise.
Perform these inspections and check outs:
Engine
: remove engine cowling; check the bolts of the attachment of the engine bed. Check
the cable and line attachments, connection of connectors, attachments of the battery. Check
the tightening of the fuel lines, air filters, exhaust system attachments (tcheck out the integrity
of the exhaust pipe springs), and check the tightness of oil and the cooling liquid radiators.
Check the looseness of the sparks which could signalize their slacking. Check the level of
oil, cooling and brake fluids, and also the level of battery solution in the accumulator. The
cooling liquid should reach 2/3 of the maximum volume of the tank (cold engine). The oil level
must be between the min and max marks. Prior to longer flights it must be at least in the
middle between the min and max marks.
Check for possible fouling of the fuel filter; replace it if necessary. If you recognize the fuel
filter fouling in the engine area, perform an extra inspection or replace the fuel filter. Watch
for possible worn out spots on the fuel lines especially at attachment points, or at locations
where they are connected to metal parts of the engine.
Carefully check the linkage of the carburetors. If you detect that some of the lines get loose
at the neck of the carburetor, even though it had been tightened, it is necessary to take it off
and replace it. Install the engine cowling.
ATTENTION
If a line is worn out conically, there is a possibility that small parts of rubber could
have gotten in to the carburetor stirrup. Let an authorized technician clean it.
Propeller:
check the attachment, possible damage, propeller cone attachment; if the
propeller is electronically adjustable check if it repositions
Nose wheel
: check the symmetry, malformation and gaps, fairing of the nose wheel, the
integrity of varnish of the nut of the safety bolt of the front wheel; tighten the nuts of the nose
wheel.
Right wing
: check the bolts, screws and safety pins in the fuselage of the airplane (after
removing the seats from the cockpit), flaps and ailerons attachments (you will have to kneel
or lie down, the attachment points are not visible from the top), check the gaps and free
movement, check the conditions and safety pins at all flap and ailerons hinges. Check the
same position of both landing flaps at all positions on both wings. Check the fuel cap.
Fuselage
: check the surface of the fuselage, possible flaws on the surface or in the varnish.
Empennage
: check freedom of movement, surface damage, position of the elevator and the
rudder (geometry). Check for the gap of the elevator and for the gap of the rudder at hinges.
Check the connection of the elevator rod, rudder and trim-tab cables.
Left wing
: the same as the right wing
The interior of the cockpit
: check the cleanness, the conditions of controls, instruments and
avionics functioning, the completeness of the documents required on the board of an airplane
Tires
: check the pattern of the tires, pressure and check for cracks and bulges. The
prescribed pressure for both tires is 1.8 kPa.
Drain valve
: drain a little amount of fuel to a vessel and check its content for contaminants
and water.
BRS
: if your airplane is equipped with rescue system, unlock it before flight
