Varga Pre-buy Inspection
Spinner – FAA no longer approves stopped drilled
cracks or doubler repairs. Replacement
– Length = 74”. Check
the trip tracking. Also, leading
edge and blade back side to be free of dings and indentations. Cost $2,500.
Cowl – Free of cracks. Good latching action. Check that attachment hardware is all the
same size. Note the gap between top
of spinner and bottom of spinner in relation to the nose bowl. Large gap at the top indicates worn
engine mount bushings.
Engine – Standard engine checks. Exhaust system requires the most
attention (springs broken). Check
mufflers and tailpipes for contact with engine mount and firewall. Oil leaks.
Condition of cowl baffles, wires and ducting. Cabin heat control box condition.
Gear – Lift nose gear and
check wheel bearings, shimmy unit, and inner cylinder surface area for pits
and/or rust. Wiggle gear and check
torque links are secure and free of cracks.
Note if it secured by pins or bolts/nuts.
Turn wheel left and right and check steering stops and freedom of travel.
– Check lower skin area around landing gear for skin wrinkles
(evidence of hard landing). Also,
area just forward of flap hinges for being deformed, that is evidence of flaps
being lowered at high rate of air speed. Push
on upper wing skin just forward of aileron hinges.
A pop sound indicates a broken wing butt rib. Move aileron full travel and note any
signs of binding. Note overall
condition of wing for hangar rash. Verify
fuel vent system is operational by removing gas cap; blow air into vent line and
note air flow at cap. Operate fuel
tank sump drain and check for free flow of fuel.
With fuel tank shut off valves closed, open drain valve on the gascolator
unit. With a container
at the gascolator, open tank shut-off valve for 5 seconds. Note fuel amount in container. Repeat for the other tank. These last 2 checks are looking for
blockage caused by fuel tank sloshing
– Place shoulder under forward wing spar and lift wing and
release. Note that gear lower
(inner) cylinder moves freely in upper (outer) cylinder. Check inner cylinder surface area for
pits and/or rust. Check brake for
wear and caliper for leaks and condition of wheel brake disc. Check torque link (same as nose gear).
Stand in front of the plane and look to see that each wheel appears to be
vertical (gear not bent).
Fuselage – Check overall condition of fuselage and
note missing screws in access panels. Remove
the one large panel under rear seat to check flight control mechanism. Verify no cracks in elevator push pull
rods and view aft fuselage area. Remove
side panel under horizontal stabilizer to check flight control area. Remove tail cone and check elevator
control horn, etc. Reinstall all
– Inspect elevator and rudder hinge fittings and hardware. Check to see if there is a shim installed
under forward stabilizer attachment angle, both sides (shim is not a factory
installation but helps reduce elevator trim forces). Note that control surfaces move
approximately the same degree each way.
– Verify throttle, carb heat,
mixture, and fuel shut off valves move freely with no binding. Note condition of cockpit glass. Check that canopy opens and closes
smoothly and latches in all positions. Verify
all fuse holders and switches are operational.
Check that stall-warning horn is operational and that all lights are
working. Check condition of
