NOTE
The comparator (AGE NO. 00062) must be
no more resetted until the test is terminated.
4.By the dynamometer (AGE NO. 00034) apply a
vertical load on the geared trim tab / right gear tab
trailing edge, close to fail safe rod and measure the
LH trim tab, RH gear tab displacement as follows:
A.Gradually apply a load upwards up to 11.24 lb
(5.10 kg) maximum, leaving out the reading on the
comparator (AGE NO. 00062).
B.Stepwise unload, every 2.25 lb (1.02 kg), up to
zero load and simultaneously read, on the
comparator (AGE NO. 00062), the related
displacement value of the left trim tab /right gear
tab.
C.Stepwise load downwards, every 2.25 lb (1.02 kg),
up to 11.24 lb (5.10 kg) maximum and
simultaneously read, on the comparator (AGE NO.
00062), the related displacement value of the left
trim tab/right gear tab.
D.Stepwise unload, every 2.25 lb (1.02 kg), up to
zero load and simultaneously read, on the
comparator (AGE NO. 00062), the related
displacement value of the left trim tab /right gear
tab.
E.Stepwise load upwards, every 2.25 lb (1.02 kg), up
to 11.24 lb (5.10 kg) maximum and simultaneously
read, on the comparator (AGE NO. 00062), the
related displacement value of the left trim tab /right
gear tab.
5.Put the value obtained in a diagram and draw a graph,
load applied Vs LH (RH) trim tab displacement.
6.To calculate correctly the backlash (refer to figure
) proceed as follows after that the
diagram load applied vs surface displacement has
been drawn:
