WARNING: MAKE SURE THAT ALL ENGINE OPERATING AREAS ARE AS CLEAN AS POSSIBLE. ALL RAMPS, TAXIWAYS, RUNWAYS, AND OTHER OPERATING AREAS MUST BE VERY CLEAN TO PREVENT SERIOUS DAMAGE TO THE ENGINE, AIRCRAFT AND INJURY TO THE PERSONS IN THE AREA.

WARNING: MAKE SURE THAT THE LANDING GEAR GROUND SAFETIES AND THE WHEEL CHOCKS ARE IN POSITION.

WARNING: BEFORE YOU OPERATE THE ENGINES AT POWER SETTINGS ABOVE IDLE, MAKE SURE THAT THERE IS NO RISK OF PRE-PRESSURIZATION OR RESIDUAL PRESSURE IN THE AIRCRAFT AFTER SUBSEQUENT ENGINE SHUTDOWN.

TO DO THIS, MAKE SURE THAT THE AIR CONDITIONING OUTFLOW VALVES ARE OPEN DURING ALL THE TEST. TO OPEN THE VALVES:

-   SET THE CABIN PRESSURE MODE TO MANUAL. THEN SET THE CABIN PRESS/MAN/V/S CTL SWITCH TO "UP". THE DITCHING FUNCTION MUST NOT BE SET TO "ON".

OR

-    SET THE RAM AIR INLET TO OPEN (THE OVERFLOW VALVES ARE THEN IN THE

50% OPEN POSITION).

IF PERSONS TRY TO OPEN A DOOR WHEN THERE IS RESIDUAL PRESSURE IN THE AIRCRAFT:

-    THE DOOR CAN OPEN WITH DANGEROUS SUDDEN FORCE, AND

-    THERE IS A RISK OF BAD INJURY OR DEATH, AND

-    THERE CAN BE DAMAGE TO THE AIRCRAFT.

3. Job Set-up

Subtask 71-00-00-210-060

A. Check the following:

(1) Make sure that all parts, tools, equipment and loose objects are removed from the engine air intake and the area around the intake.

(2) Do a visual check for damage or ice on the fan inlet, fan blades, fan spinner, inlet temperature sensors, fan duct, and external cowl surfaces. If you find ice on these parts, you must thaw the engine with hot air. After the engine is thawed, check to see that the fan rotor turns freely (Ref. AMM TASK 71-00-00-660-802) .
