(2)
Make sure that the Gaussmeter operates correctly:
-the pointer must move when you put the instrument near the shaft of the windshield wiper motors.
(3)
With the Gaussmeter, find the magnetic zones of the external parts of the frames of the windshield and sliding windows. Record the value for each zone.
NOTE : Ignore the magnetization on the shaft of the windshield wiper
____
motors.
Subtask 05-54-00-869-050
B. Demagnetize:
(1)
Obey the instructions from the manufacturer for the DEMAGNETIZER -110V/60HZ (DM05275A) or the DEMAGNETIZER - 220V/50HZ (DM05275B).
(2)
Energize the demagnetizer.
(3)
Put the demagnetizer at a very small distance (1 cm approx.) from the part it is necessary to demagnetize. This position gives the reference plane.
(4)
Push the power supply button (indicator light on) and keep the demagnetizer above the magnetic zone during 2 to 3 seconds. Then move the demagnetizer away slowly at a constant speed and at right angles to the reference plane. You must move the demagnetizer to a minimum distance of 50 cm approx. before you release the button.
(5)
Do the step (4) again for each zone that you must demagnetize.
(6)
De-energize the demagnetizer.
(7)
For each demagnetized zone, read the value shown on the Gaussmeter. Make sure that this value is near zero.
(8)
If you find zones that are not fully demagnetized, do again the step
(4) until the value read on the Gaussmeter is near zero.

LEVELING AND MEASUREMENT AFTER A/C ABNORMAL OPERATION - INSPECTION/CHECK
________________________________________________________________________
TASK 05-56-00-200-001
Inspection/Check of the Leveling and Measurement after Abnormal Operation of the Aircraft
1. Reason for the Job
__________________
This topic gives the instructions for the leveling, measurement and
alignment operations of the aircraft.
You can compare these checks with subsequent measurements to find possible
structural deformations after hard landings, too much turbulence, etc.
Do these checks after the replacement or major repair of a part of the
structure.
