3. Job Set-up
Subtask 05-25-00-860-050-A

A. Aircraft Maintenance Configuration
(1) Tow the aircraft in a hangar.
(2) Put the CHOCK - WHEEL(S) in position (Ref. AMM TASK 10-11-00-555-015).
(3) Close the hangar doors.
(4) Extend the spoilers (Ref. AMM TASK 27-60-00-866-002).

WARNING: DO NOT EXTEND THE SLATS AND FLAPS WHEN THE THRUST REVERSER COWLS ARE DEPLOYED IN THE 45 DEG. POSITION.

(5) Fully extend the flaps and the slats (Ref. AMM TASK 27-50-00-866-008) and (Ref. AMM TASK 27-80-00-866-004).
(6) Make sure that the Trimmable Horizontal Stabilizer (THS) and the rudder are in neutral position.
(7) Make sure that the engines are installed.
(8) Make sure that all the aircraft openings that follow are closed:

Passenger/crew doors
Emergency exit doors
Cargo compartment doors
APU doors
Engine cowls: Fan cowl doors and Thrust Reverser doors
Landing gear doors
Service panels.

(9) De-energize the aircraft electrical circuits
(Ref. AMM TASK 24-41-00-862-002).
(10) Make sure that no part of the aircraft is missing in the area inspected by the DCL90-00001 ADVANCED INSPECTION DRONE.
(11) Make sure that the light conditions in the hangar do not cause reflections on the aircraft skin in the inspection areas.
If they do, stop the ceiling lights, do the inspection with the DCL90-00001 ADVANCED INSPECTION DRONE later or do the alternative inspection method.
