*** WARNING ***
Smoking on or around the aircraft is not permitted during the
defueling procedure. Fire protection equipment must be
immediately available.
A.
Ground aircraft and all defueling equipment or containers to the aircraft.
B.
Place vented container of adequate capacity under the three drain points. Verify that the
containers are properly grounded to the aircraft.
C.
Open the drain valves and allow all fuel to drain.
D.
Close the drain valves and move the fuel containers to a safe distance from the aircraft.

Verify that all the drain valves are closed.
INDUCTION SYSTEM
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 the -45, -60, and -67 engines for proper
internal cleaning.
** CAUTION **
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. This is acceptable if extremely corrosive chemicals
are not being used.
