N. Inspect propeller governor for evidence of leak-
age and mounting security.
O. Inspect engine for proper set--up. (See TCM
Service information for TSIO--550--G engine and Sec-
tion 71--00--50).
P. Inspect battery cables, electrical wiring, and
ignition harness for condition, secure anchorage, loose
terminals, and burned or chaffed insulation.
Q. Inspect batteries, battery mount areas, and vent
system (as applicable) for condition and corrosion. In-
spect blast tube for obstruction (as applicable). Flush
battery mount areas with soda solution to neutralize
corrosive action, if necessary.
R. Inspect exhaust system for cracks, looseness
and for evidence of leakage. Replace or repair dam-
aged area.
S. Inspect exhaust stacks and breather tubes for
burned areas, cracks, oil coking, deposit build-up, dis-
tortion and looseness ( also see MAC SB M20--312).
T. Inspect air conditioning compressor installation,
belts, connections (if installed). Reference SECTION
21--58--00.
U. Inspect studs, nuts, bolts, etc. for damage and
proper torque.
V. Inspect exhaust couplings, seals, clamps and
slip--joints for cracks, deformation, leaks and security.
W. Inspect and re--install cowling.
2. PROPELLER INSPECTION.
A. Remove spinner (if not already removed).
B. Inspect security of propeller installation.
C. Inspect hub studs/nuts/bolts for proper torque
(ref. 61--00--20), security and damage.
D. Inspect hub components for damage and leaks,
and blades for cracks and nicks. Repair prior to next
flight.
E. Inspect spinner and bulkhead for cracks and
condition.
F. Inspect spinner & bulkhead for snug fit between
propeller hub cylinder and rear bulkhead. Use shims as
necessary for snug fit.
3. LANDING GEAR and RETRACTION SYSTEM
INSPECTION.
A. Inspect tires for proper inflation, cuts, blisters,
slippage and excessive wear. Replace with new, ap-
proved, tire(s), if necessary.
-- CAUTION --
Always run at least 5 complete Landing Gear Re-
traction Cycle checks after any tire has been re-
moved and/or replaced, before flying the aircraft.
B. Inspect wheels for cracks, distortion, misalign-
ment, corrosion and bolt failure. Inspect condition of felt
seals and bearings; re--pack bearings at 100 hour inter-
vals.
C. Inspect brakes for disc and pad wear, and disc
warpage (Ref. Section 32--40--04).
D. Inspect hydraulic reservoir for proper fluid level.
E. Inspect hydraulic brake lines and hoses for leak-
age, dents, cracks chafing, kinks and security.
F. Inspect parking brake system for proper en-
gagement and release.
G. Check shock disc gap on main and nose gear
(Ref. 32--81--00).
Jack aircraft, as recommended in paragraph 7--10--00,
for the following inspections:
H. Hard landing inspection (ref. 32--82--00).
I. Inspect nose gear for cleanliness and damage.
Inspect nose gear retraction tube bungees for sheared
or broken roll pins.
NOTE:
Maximum allowable towing damage on leg as-
sembly is 1/32 inch dent. No repair is allowed on
heat treated landing gear components.
J. Inspect nose wheel steering mechanism for ad-
justment, alignment, corrosion, and lubrication.
K. Inspect main gear for cleanliness and damage.
L. Inspect landing gear retraction linkage, bell-
cranks, pivots and bearings for wear, damage, distor-
tion, misalignment, corrosion, cleanliness, and lubrica-
tion.
M. Inspect landing gear actuator for security of
mounting, cleanliness, and indication of overheating
and damage. Check motor operation and brush wear.
N. Perform landing gear operational check per
Section 32--30--01.
4. FUEL SYSTEM INSPECTION.
A. Inspect fuel tank exterior for evidence of fuel
seepage and stain.
B. Drain tank and inspect tank interior when seep-
age is evident.
C. Inspect fuel tank drains for leakage, sediment,
and water contamination.
D. Inspect fuel--tank vents for obstruction.
E. Inspect fuel selector valve for proper tank selec-
tion, positive valve selection through range of rotation,
smooth operation and any leakage when in OFF posi-
tion.
F. Inspect gascolator for leakage; inspect sump for
sediment, water and other contamination.
G. Inspect electric boost pump for leaks, security of
mounting, switch operation, and condition of wiring and
electrical connections.
H. Inspect fuel quantity gauges and transmitters
for security of mounting and condition of wiring and
electrical connections.
