Airframe Lubrication

Proper lubrication procedures are valuable for prolonging the service life of the airplane and as a means
of reducing the frequency of extensive and expensive repairs. The periodic application of recommended
lubricants to relevant bearing surfaces combined with cleanliness, as detailed in the following
paragraphs, ensures maximum efficiency and utmost service of all moving parts. Lubrication instruction
regarding locations, time intervals, and type of lubricants used are found in proper lubrication charts. To
ensure the best possible results from lubricant application, observe the following precautions:
NOTE: If the airplane is inactive for long periods of time, it should be lubricated in accordance with the
Lubrication Chart every 90 days.
A. Use only recommended lubricants. Where general purpose lubricating oil is specified, but
unavailable, clean reciprocating engine oil is a satisfactory substitute.
B. Check components for evidence of excessive wear and replace as necessary.
C. Removal all excess lubricants from components to prevent collecting dirt and sand in quantities
capable of causing excessive wear or damage to bearing surfaces.
2.

Application of Grease

When lubricating bearings and bearing surfaces with a grease gun, ensure gun is filled with new, clean
grease specified for the particular application before applying lubricant to grease fittings.
A. If a reservoir is not provided around a bearing, apply lubricant sparingly and wipe off excess.
B. Remove wheel bearings from wheel hub and clean thoroughly with suitable solvent. When
repacking with grease, ensure lubricant enters space between rollers in retainer ring. Do not pack
grease into wheel hub.
C. Use extra care when greasing Hartzell propeller hub to avoid blowing clamp gaskets. Remove one
grease fitting while applying grease to other fitting. Uneven greasing effects propeller balance.
3.

Application of Oil

If specific lubrication instructions for certain components are not available, observe the following
precautions:
CAUTION: AFTER THOROUGHLY WASHING AIRPLANE, ENSURE LANDING GEAR, FLIGHT
SURFACE WINGS, FLAP TRACKS, ELEVATOR TRIM SCREW, AND ENGINE
COMPARTMENT ARE STILL PROPERLY LUBRICATED.
A. Apply oil sparingly. Never apply more than enough to coat bearing surfaces.
B. Do not oil control cables.
