Parking Periodic Ground Checks

TASK 10-11-00-555-804-A
Parking Periodic Ground Checks

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).
CAUTION: BE CAREFUL WHEN YOU USE ALUMINIUM-FOIL ADHESIVE FILM-TAPE 05RAB9 BECAUSE OF ITS HIGH ADHESION CAPACITY. THIS TAPE CAN CAUSE DAMAGE TO THE PAINT DURING THE REMOVAL OF THE TAPE.
1. Reason for the Job
This procedure gives the periodic ground checks that are necessary when the aircraft is parked in flight-ready condition:
  • At 7-day intervals
  • At 15-day intervals
  • At 1-month intervals
  • At 3-month intervals
  • At 1-year intervals.

A. General Information.
   (1) During the parking period, you must do ground checks.
The steps to be done for the periodic ground check procedure are given in a table. You must do each step identified with a cross in the column related to the applicable periodic ground check interval(s).
   (2) For the ground checks during a parking period of "Not more than 1 month" and a parking period of "More than 1 month", refer to the columns that follow:
  • At 7-day intervals: column "p7d"
  • At 15-day intervals: column "p15d"
  • At 1-month intervals: column "p1m"
  • At 3-month intervals: column "p3m"
  • At 1-year intervals: column "p1y".
NOTE: You can do a periodic ground check earlier in the specified interval in relation to your operational conditions.
You can do the different ground checks at the same time.
   (3) You must do the applicable steps in the sequence that is given in the table.

K. Engine, APU and System Periodic Checks
NOTE: ATA 10 gives instructions related to the parking, storage, periodic checks and return to operation of the aircraft. These instructions do not include the engine and APU manufacturer recommendations.
For the parking, storage, periodic checks and return to operation of the engines and the APU, ATA 10 refers to the applicable procedures in the related ATA chapters (7X and 49).
This subtask gives two tables that are complementary and can be done together.
The table (1) gives the engine and APU manufacturer recommendation periodic checks.
The table (2) gives the system tests.
Get all the necessary information to optimize the maintenance periodic interval:
  • The engine and APU manufacturer recommendations for the regular checks and the possible engines and APU starting,
  • The aircraft/nacelle system tests.
Then optimize the maintenance instructions given in the two tables.
For example:
  • Removal and installation of the aircraft protection devices,
  • De-preservation, start, test, stop and preservation of the engines and APU.
