Return to Operation After a Parking Period

TASK 10-30-00-554-804-A
Return to Operation After a Parking Period

WARNING: BEFORE YOU OPEN AN AIRCRAFT DOOR, MAKE SURE THAT THE CABIN IS NOT PRESSURIZED. TO DO THIS, MAKE SURE THAT: - THE AIR CONDITIONING GROUND-CART IS NOT CONNECTED TO THE AIRCRAFT, AND - THE FORWARD AVIONICS-COMPARTMENT ACCESS-DOOR 811 IS OPEN. IF THERE IS REMAINING PRESSURE IN THE AIRCRAFT, THE DOOR CAN OPEN WITH A SUDDEN FORCE. THIS CAN CAUSE INJURY TO YOU OR KILL YOU, AND/OR CAUSE DAMAGE TO THE AIRCRAFT.
WARNING: BE CAREFUL WHEN YOU USE CONSUMABLE MATERIALS. OBEY THE MATERIAL MANUFACTURER'S INSTRUCTIONS AND YOUR LOCAL REGULATIONS.
WARNING: DO NOT USE THE EMERGENCY LIGHTS TO ILLUMINATE THE CABIN DURING MAINTENANCE. IF YOU USE THE EMERGENCY LIGHTS DURING MAINTENANCE, YOU CAN DECREASE THE LIFE OF THE EPSU BATTERIES AND THEIR INTERNAL VOLTAGE. IF THE INTERNAL VOLTAGE OF THE EPSU BATTERIES IS TOO LOW WHEN YOU CHARGE THEM, THERE IS A RISK OF EXPLOSION.
CAUTION: DURING STORAGE OR PARKING PERIODS, DO NOT STOP OR CHANGE THE MAINTENANCE PROGRAM UNLESS IT WAS AGREED BY THE LOCAL AUTHORITIES. THE MAINTENANCE CALENDAR CLOCK CONTINUES DURING THESE PERIODS. IF YOU DO THE AMM STORAGE OR PARKING PROCEDURES CORRECTLY, AND IF YOU HAVE THE AGREEMENT OF THE LOCAL AUTHORITIES, IT IS NOT NECESSARY TO DO ALL THE SCHEDULED MAINTENANCE TASKS (SUCH AS MPD TASKS) IMMEDIATELY DURING THE STORAGE/PARKING PERIOD. YOU CAN WAIT UNTIL THE END OF THE PERIOD. BUT YOU MUST DO THEM ALL BEFORE THE NEXT FLIGHT.
CAUTION: DURING THIS PROCEDURE:
  • MAKE SURE THAT THE LANDING GEAR GROUND SAFETIES, LOCKING DEVICES AND WHEEL CHOCKS ARE IN POSITION.
  • KEEP THE ACCESS PLATFORM AT A SUFFICIENT DISTANCE FROM THE AIRCRAFT (IN WIND, SHOCK ABSORBER REBOUND CAN CAUSE MOVEMENT OF THE AIRCRAFT).
1. Reason for the Job
This procedure gives the instructions necessary for the return-to-operation of the aircraft after a parking period.
You must complete the return-to-operation procedure at a time, when the aircraft will fly in the 24 hours that follow unless specified differently by the applicable national authority regulations.
If the return-to-operation procedure is immediately followed by large maintenance operations, the aircraft must fly immediately after the signature of the Certificate of Release to Service (CRS) document. During maintenance, it is necessary to find and use an applicable preservation procedure.
It is necessary to do a flight to reset a parking period.
