A. Several basic characteristics of tubeless aircraft tires may be mistaken for problems:
(1) Tire growth in the first 12 to 24 hours after inflation will result in a seemingly severe pressure
drop. Simply inflate, wait for another 24 hours, then check pressure. It will probably be within
specs.
(2) Make sure that initial inflation is to recommended operating pressure to ensure full tire growth.
(3) It is normal for tubeless tires to show a small amount of pressure leakage throughout the life of
the tires.
B. Maintain tires at pressure specified in Chart 1 (Sheet 2 of 2), 6-00-00. When checking tire pressure,
examine tires for wear, cuts, bruises, and slippage. Apply Age-Master #1 to tires to protect against
ozone attack and weathering as follows:
(1) Clean oil and grease from all tire surfaces.
(2) Apply single heavy coat using brush at 0.4 - 0.5 fluid ounces per square foot. Cover surface
completely and evenly; allow to dry for 5 - 10 minutes.
(3) Apply second coat per step B; allow to dry for 20 - 30 minutes before handling.
(4) Remove agent on wheel assembly with cleaning solvent.
(5) Apply as conditions dictate.
6. Hydraulic System
The general condition of the hydraulic pump and landing gear actuating cylinders should be checked.
Ensure that there are no leaks and that the line fittings are tight. The cylinder rods are to be free of all
dirt and grit. To clean the rods use a rag soaked in hydraulic fluid and carefully wipe them. All the
hydraulic lines should also be checked for leaks, kinks, and corrosion. Check the tightness of the
attachment fittings.
Repair and inspection procedures for the hydraulic pump, cylinders and various components may be
found in 29-10-00 of this manual.
Servicing Hydraulic Pump/Reservoir
The fluid level of the reservoir of the combination pump and reservoir should be checked every 50
hours by viewing the fluid through the transparent reservoir on the hydraulic pump. Access to the
pump is through view port in rear baggage compartment panel behind rear seat.
Should fluid be below the full mark, add fluid MIL-H-5606 through the filler hole until full. Ensure that
the landing gears are down and the flaps up when filling the reservoir. Reinstall the filler plug and
tighten.
7. Engine Lubrication
CAUTION: DO NOT INTRODUCE ANY TRADE ADDITIVE TO THE BASIC LUBRICANT UNLESS
RECOMMENDED BY THE ENGINE MANUFACTURER.
A. General
(1) The engine oil and oil filter should be changed every 50 hours of engine operation (or less,
depending upon dust, humidity or engine conditions) or every 4 months, whichever comes first.
(2) For new, overhauled or re-manufactured engine, use ashless dispersant oil conforming to
MIL-L-22851 specifications. After 25 hours, change oil and filter.
(3) It is recommended after the first 25 hours of engine operation that the operator continues to
use ashless dispersant oil conforming to MIL-L-22851 specifications.
