The prime difference between the agricultural and a normal installation is the air cleaning

system incorporated in the engine air intake system. The air filter is located below the

engine air inlet plenum between the center and rear fire seals and is a washable reusable

barrier type filter.POWER PLANT INTERNAL CLEANING

Refer to Pratt & Whitney Canada Maintenance Manual for proper internal cleaning.

Chemicals should not be allowed to remain in an engine any

longer than overnight, and a water wash should not be

performed any sooner than 45 minutes after shutdown. It

may be more convenient and practical to wash the engine

before working the next morning.

extremely corrosive chemicals are not being used.

Check all gear assemblies for general cleanliness, security of mounting, and hydraulic

leaks at prescribed inspection intervals. Lubricate all lubrication points on main and tail

gear assemblies at prescribed intervals.

Tires should be inspected for proper inflation, breaks, cuts, and foreign objects in tread,

flat spots and exposed cord. Replace tire if there is any question of its reliability. Proper

inflation is necessary for maximum tire life. Maintain 29x11-10pr main wheel pressure at

a minimum of 40 psi to a maximum of 62 psi, depending on the load and runway

conditions. 6.00-6 8pr tail wheel tire pressure should be 55 psi maximum. The wheels

and tires are balanced assemblies. If tires are suspected of being out of balance, they

may be balanced on automotive type balancing equipment. If aircraft is out of service,

rotate tires every seven days to prevent flat spots from developing.

Brake bleeding should be performed when air is suspected of being entrapped in brake

lines. See Section Six for brake bleeding procedures.

Only the items to be inspected are listed and details as to how to check or what to check

for are generally excluded. Those checks can be found in specified Section of this

manual.
