TASK 73-29-00-710-040-B
Operational Test of the FADEC on the Ground (with Engine Motoring)
WARNING: BE CAREFUL WHEN YOU DO WORK ON THE ENGINE PARTS AFTER THE ENGINE SH
UTDOWN. USE APPLICABLE THERMAL GLOVES. THE ENGINE PARTS CAN STAY HOT
FOR ONE HOUR AFTER SHUTDOWN AND CAN BURN YOU.
WARNING: MAKE SURE THAT ALL ENGINE OPERATING AREAS ARE AS CLEAN AS POSSIBLE. A
LL RAMPS, TAXIWAYS, RUNWAYS AND OTHER OPERATING AREAS MUST BE VERY
CLEAN TO PREVENT BAD DAMAGE TO THE ENGINE, AIRCRAFT AND PERSONS IN T
HE AREA.
WARNING: DO NOT TRY TO STOP THE FAN FROM TURNING BY HAND. THIS CAN CAUSE INJUR
Y TO THE PERSONS AND DAMAGE TO THE EQUIPMENT.
WARNING: MAKE SURE THAT THE LANDING-GEAR GROUND SAFETY-LOCKS AND THE WHEEL C
HOCKS ARE IN POSITION. MOVEMENT OF THE AIRCRAFT CAN BE DANGEROUS.
WARNING: MAKE SURE THAT THE TRAVEL RANGES OF THE FLIGHT CONTROLS SURFACES ARE
CLEAR. MOVEMENT OF FLIGHT CONTROLS CAN CAUSE INJURY TO PERSONS AND/
OR DAMAGE TO EQUIPMENT.
CAUTION:
- SEE THE APPLICABLE FIGURE FOR WIND LIMIT RESTRICTIONS WHEN THE ENGI
NE OPERATES.
NATURAL WINDS AND IRREGULAR FORCES FROM SUDDEN GUSTS INCREASE
THE DANGEROUS AREA.
-
DO NOT GO ABOVE OPEN COWLING LIMITATIONS WHEN YOU DO THE TEST
S.
-
THE OPERATOR MUST FULLY KNOW ALL THE OPERATING LIMITS AND PROC
EDURES BEFORE THE ENGINE OPERATES.
CAUTION:
DO NOT REPLACE AN IDLE LEAK CHECK BY A MOTORING TEST. YOU CANNOT DETE
CT POTENTIAL OIL LEAKS WITH A MOTORING TEST. IF YOU DO A MOTORING TES
T INSTEAD OF AN IDLE LEAK CHECK, YOU CAN CAUSE AN ENGINE SHUTDOWN.
CAUTION:
MAKE SURE THAT THERE IS NO HYDRAULIC GROUND POWER SUPPLY CONNECTED
TO THE AIRCRAFT WHEN YOU DO THIS PROCEDURE. IF A HYDRAULIC GROUND PO
WER SUPPLY IS CONNECTED, THERE IS A RISK OF DAMAGE TO THE ENGINE PUMP
