Ignition System
42.
Engine ignition is provided by two engine driven magnetos which fire two spark plugs per
cylinder. Ignition and starter operation is controlled by a key-operated rotary switch on the lower
instrument panel labelled OFF, R, L, BOTH and START. The engine should be operated with
the ignition switch in the BOTH position except for magneto checking and emergency
purposes.

Starter
43.
The aircraft is equipped with a high energy starter. When the master switch is in the ON
position and the rotary ignition switch is rotated to the START position, the starter will engage.
44.
The starter motor is equipped with an adapter that is subject to progressive breakdown
and failure through normal use. When the starter is engaged, a properly functioning adapter will
immediately begin turning the propeller. A starter adapter that slips, slowly or intermittently
turns the propeller indicates a serious malfunction which immediately renders the aircraft
unserviceable until assessed by an RCA Ops (Pac) AME. These conditions can result in metal
flakes entering the engine oil system; They are not indicators of a minor progressive breakdown
where the aircraft can continue operating so long as it ultimately starts.
CAUTION
Do not engage the starter while the propeller is turning.
CAUTION
The engine may partially fire on start, usually due to insufficient
priming. When this occurs, immediately release the starter and allow
the engine to either fully catch or quit. Do not keep the starter
engaged in an attempt to keep the engine running.
CAUTION
Do not engage the starter for periods longer than 30 seconds as the
starter may overheat. If the starter has been engaged for an
