Revision 6

NEW ENGINE BREAK–IN AND OPERATION
The engine has undergone a break–in at the factory and is ready for the full
range of use. It is, however, recommended that cruising flights be
accomplished at 65 to 75 % until a total of 50 hours has accumulated or oil
consumption has stabilized.
The airplane is delivered from the factory with corrosion preventive engine
oil. If, during the first 50 hours, oil must be added, use only aviation grade
straight mineral oil in compliance with Specification MIL–L–6082.
Use dispersant oil in compliance with Specification MIL–L–22851 only after
the first 50 hours.
ENGINE LUBRICATION SYSTEM (See Figures 7.12 and 7.12A )
The engine is lubricated by an oil system powered by a pump located on
engine rear accessory housing. A sump located at the bottom of the engine
allowing oil recovery, a cartridge throw–away type filter located on engine
rear accessory housing and a strainer type filter located in the sump complete
the system.
A pressure probe and a temperature probe transmitting the values to two
indicators located on upper edge of the console enable the pilot to check the
oil system.
An inspection door located on engine upper cowl provides access to oil
system filling port.
A dipstick attached on the port blanking cap enables to check oil level in the
sump. A union located under the engine case enables a quick drain of the
latter.
AIR INDUCTION SYSTEM
The engine is supplied with an air intake located under the propeller cone.
This air intake is fitted with a filter which removes dust and other foreign
matters from the induction air so that they do not penetrate into the air duct.
However, in the event the air filter becomes blocked, pull on ”Alternate Air”
control to open an alternate air door allowing air to enter the engine.
For flights in sandy or dusty atmosphere, install a second specific filter.
