Tire Inflation
For maximum service from the tires, keep them inflated to the proper
pressure. When checking tire pressure, examine the tires for wear,
cuts, nicks, bruises and excessive wear.
To inflate tires:
1. Remove inspection buttons on wheel pants to gain access to valve
stems. It may be necessary to move airplane to get valve stem
aligned with the access hole.
2. Remove valve stem cap and verify tire pressure with a dial-type
tire pressure gage.
3. Inflate nose tire to 30 psi (207 kPa) and main wheel tires to 62 psi
(427kPa).
4. Replace valve stem cap and inspection buttons.
All wheels and tires are balanced before original installation and the
relationship of tire, tube, and wheel should be maintained upon
reinstallation. In the installation of new components, it may be
necessary to rebalance the wheels with the tires mounted.
Unbalanced wheels can cause extreme vibration in the landing gear.
Propeller Servicing
The spinner and backing plate should be cleaned and inspected for
cracks frequently. Before each flight the propeller should be inspected
for nicks, scratches, and gouges. 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.
Propeller blades are painted with a durable specialized coating that is
resistant to abrasion. If this coating becomes eroded, it is necessary to
repaint the blades to provide proper erosion protection. Painting
should be performed by an authorized propeller repair station.
It is permissible to perform a blade touch-up with aerosol paint in
accordance with the appropriate revision of the Hartzell Propeller
Owner’s Manual (p/n 145).
Oil Servicing
The oil capacity of the Teledyne Continental IO-550-N engine is 8
quarts. It is recommended that the oil be changed every 50 hours and
