Engine Ground Test and Safety Precautions

A. Prior to ground testing the engine, the following safety precautions should be adhered to:
(1) Position the airplane into the wind.
(2) Set the parking brake and chock the wheels.
NOTE: The importance of placing chocks in front of the wheels cannot be overstressed. It is
possible for the airplane to move with just the brakes applied when the power being applied
exceeds 600 foot-pounds of torque.
(3) Be certain a fire extinguisher is readily available.
(4) Be certain the area around the airplane is free of loose objects.
(5) Check that the engine intakes and exhausts are free from foreign objects.
(6) Ascertain that the danger areas around the airplane are clear of personnel.
B. Ascertain the engine indicating systems are properly calibrated.
C. Install and secure the cowling, if not already installed.
CAUTION: BEFORE ATTEMPTING TO START THE ENGINE, PERSONNEL SHOULD BE
CHECKED OUT BY A QUALIFIED PILOT OR OTHER RESPONSIBLE PERSON ON
THE ENGINE STARTING AND SHUTDOWN PROCEDURES, AND ANY OTHER
SYSTEM FUNCTIONS WHICH MAY BE REQUIRED TO PROPERLY AND SAFELY
OPERATE THE POWER PLANT. THE USE OF THE PILOT'S OPERATING
HANDBOOK FOR THIS INFORMATION IS MANDATORY.
WARNING: STABILIZED GROUND OPERATION BELOW 1200 RPM (N P ) CAN GENERATE HIGH
PROPELLER STRESSES AND RESULT IN FATIGUE DAMAGE TO THE
PROPELLER. THIS DAMAGE CAN LEAD TO A REDUCED PROOELLER FATIGUE
LIFE, PROPELLER FAILURE, AND LOSS OF CONTROL OF THE AIRCRAFT.
CONTACT THE PROPELLER MANUFACTURER FOR CORRECTIVE ACTIONS IF A
PROPELLER RESTRICTION OR LIMITATION IS VIOLATED.
D. Start the engine and idle three to five minutes. Cycle the propeller while running. Check the inter-
turbine temperature and torque indicators for proper operation.
