AIRPLANE OPERATIONAL AND FUNCTIONAL CHECK
1. DESCRIPTION
The following check must be performed before and after the Scheduled Maintenance Inspection to detect
any airplane abnormalities or malfunctions. A portion of the check is accomplished with the engine running
and warmed up.
The technician performing these checks must initial each box in the appropriate column to indicate comple-
tion of that step. Note any abnormalities in the notes column on the right. Spaces at the end of the checklist
are provided for recording engine parameters.
WARNING: In order to perform the following check the engine must be operating. Do not stand or
let anyone else stand close to the arc of the airplane’s propeller while conducting this
check.
CAUTION: During all engine operations outlined in this check, exercise caution to avoid harm or dam-
age to personnel and equipment due to propeller blast and rotating propeller blades.
CAUTION: Excessive engine temperatures must be avoided since run-up temperatures must closely
parallel in-flight temperatures.

tion for obstructions.
