1. The pre-flight check of the YAK-9p fighter was carried out as
follows:
Prior to starting the engines, the pilot circled the aircraft,
giving it a visual check. He checked the fuel tanks, gear,
ailerons, and elevator, and made sure that the pitot cover and
locks were removed. The cowling was removed from the engine and,
as the mechanic operated various controls in the cockpit, the
pilot looked for leaks from the lines to the engines. The cowl-
ing was then replaced and the pilot entered the aircraft. This
check was SOP and was performed each morning as well as every
time the aircraft was refueled. Because of very poor maintenance
at the Pilots' Training School, the above check was also made
before each flight.
2. The starting procedure was as follows:
The battery was switched on, the primer pumped, the propeller was
pitched forward, the throttle was cracked, the engine compression
air starter valve was opened, the booster coil energizing button
was depressed, the magneto switch was turned to 1 plus 2 position,
the throttle was worked until the engine started and the engine
compression air starter valve was closed. ?
