2.7 Lubrication
Periodic lubrication of moving parts insures proper operation and considerably extends the life of
the parts. Lubrication type, points and intervals are listed in the next paragraph and detailed in the
ANNEX A (Document & Miscellaneous group)
.
Avoid excessive lubrication as this may cause external surfaces of hinges and bearing to collect
dirt and dust. If part is not lubricated using a grease gun, grease part by hand removing excess. No
maintenance operations are allowed on the wheel bearings because they are sealed and, thus,
only replacement is prescribed as indicated in ANNEX A (FIXED or RETRACTABLE Landing
Gear).
NOTE
Use grease type Svitol Silikon Spry or equivalent. Mobil grease 27 is a Synthetic aviation grease
that can be alternatively be used in substitution of the above mentioned Silikon grease.
NOTE
Lubrication intervals strongly depends on use and environmental conditions. Generally speaking,
lubrication intervals need to be more frequent as aircraft use increases and when environmental
conditions are dry and hot.
