5-20-00 - SCHEDULED MAINTENANCE CHECKS
Inspection Intervals. Perform a 25, 50, or 100- hour in-
spection of the aircraft, components and engine at rec-
ommended intervals as outlined in the following para-
graphs.
-NOTE-
Aircraft operated in a salt air environment are
considered high risk for corrosion damage, and
should be cleaned and inspected at frequent in-
tervals. Refer to AC 43- 4.
5-20-01 - INSPECTION CHECK POINTS
The general points to be covered during inspection are
grouped in accordance with the nature and function of
the items discussed.
1. Moving Parts shall be inspected and checked as
applicable for: proper operation, security of attach-
ment, sealing, cleanliness, lubrication, servicing, safe-
tying, adjustment, tension, travel, condition of hinges,
binding, excessive wear, cracking, corrosion, deforma-
tion, and any other apparent damage.
2. Metal Parts shall be inspected, as applicable, for:
security of attachment, condition of finish and/or seal-
ant, distortion, fatigue cracks, welding cracks, corro-
sion, and any other apparent damage. The tubular
frame structure should be inspected during each annu-
al inspection for any signs of corrosion or damage.
3. Fuel, air, oil and hydraulic oil lines and hoses shall
be inspected as applicable for: cracks, dents, kinks, de-
terioration, obstruction, chaffing, improper bend radius,
and insecure installation. Replace or correct if any of
these conditions exist. Hose clamp installations on fuel
and hydraulic systems between systems or between
systems and the engine shall be torqued to 25 inch
pounds. Hose clamp installations on blast tubes, air
ducts, drain and vent lines shall be torqued to 15 inch
pounds.
4. Pipe Threads - Tightening and torque procedures.
Lubricate pipe threads as follows:
Oxygen Lines - Use only MIL- T- 5542 thread com-
pound or Teflon thread seal tape on threads of valves,
connectors, fittings, parts or assemblies which might
come in contact with oxygen. The thread compound
must be applied sparingly to the first three threads of
the male fitting only. No compound is to be used on the
coupling sleeves or on the outside of the tube flares.
Extreme care should be exercised to prevent the con-
tamination of the thread compound or Teflon tape with
oil, grease or other lubricant.
Fuel, Hydraulic, Air, Oil Lines - Use “Permatex Anti-
Seize” or equivalent on male fittings only. Apply lubri-
cant, omitting the first two threads, sparingly and care-
fully.
Engine Fittings - Use only aircraft engine oil to lubri-
cate fittings threaded directly to engine.
Tapered Threads - Use Teflon Threadseal Tape.
(1) Continue to tighten until fitting is correctly posi-
tioned but do not overrun or backoff.
(2) If leaks are detected, tighten one full turn more.
(3) If leaks persist, the parts should be discon-
nected and; rejected; replace with new components.
5. Bolts and nuts in critical areas shall be inspected
for: fretting, wear, damage, stretch, proper torque, (See
Following Tables) and safetied.
6. Electrical wiring shall be inspected as applicable
for: loose, corroded, and broken terminals; chaffed,
broken, and worn insulation; insecure installation; heat
deterioration; and any other apparent damage.
7. Filters and screens shall be removed, cleaned and
inspected for contamination or damage that would re-
quire replacement.
