HANDLING AND SERVICING
8.5 SERVICING
8.5.1 TIRE SERVICING
The main landing gear wheel assemblies use 4.00 x 6 tires. The nose wheel
assembly uses a 4.00 x 4 tire. For maximum service from the tires, keep
them inflated to the proper pressure
Nose wheel tire (recommended): 26 psi (1.8 bar)
Main wheel tires (recommended): 40 psi (2.8 bar)
When checking tire pressure, examine the tires for wear, cuts, nicks, bruises
and excessive wear.
8.5.2 BRAKE SERVICING
Brake Hydraulic Fluid Replenishing
The brake system is filled with DOT-4 hydraulic brake fluid. The fluid level
should be checked at every oil change and at the annual / 100 h inspec-
tions, replenishing the system when necessary.
To replenish brake fluid:
1 Chock tires and release parking brake.
2
Clean area around the brake handle before opening reservoir cap
itself.
3 Remove cap and add DOT-4 hydraulic fluid.
4 Install cap, check brakes, inspect area for leaks.
8.5.3 PROPELLER
The spinner and backing plate should be cleaned and inspected for cracks
frequently. Before each flight the propeller should be inspected for dents,
scratches, as well as corrosion on visible metal parts. If found, they should
be repaired as soon as possible by a rated mechanic, since a nick or scratch
causes an area of increased stress which can lead to serious cracks or the
loss of a propeller tip. The back face of the blades should be repainted when
necessary with flat black paint to retard glare. Refer to Propeller Mainte-
nance Manual for detailed information.
