2.4.
6
Compare the left and right reference point readings. If the readings are not the same, adjust the main jacks
and do the check again.
2.5 Deformation and Symmetry Check
Refer to Fig. 1 thru Fig. 3
2.5.
1
Put the Transit theodolite (Pt.No. T05-005) in position so that readings can be taken from a measuring tape
suspended from Reference Points 2, 3, 4, 5, 6, 7, 10 and 13.
2.5.
2
Set up the theodolite:
2.5.
2.1
Adjust the tripod to allow readings to be taken at a level approximately 100 to 200 mm (3.9 to 7.9 in) below
lowest point of fuselage.
2.5.
2.2
Level the theodolite head by turning leveling adjuster to match bubble halves visible through the small leveling
eyepiece.
2.5.
3
Hold the tape measure against the RP 6 left, with the zero mark at the center of the painted rivet head, and
approximately 1 m (39 in) of tape exposed so that the scale faces the theodolite.
2.5.
4
Zoom and focus the theodolite on the tape and make a note of the readings from the measuring tape. Make a
record on the check form.
2.5.
5
Hold the tape measure against the RP 6 right.
2.5.
6
Zoom and focus the theodolite on the tape and make a note of the readings from the measuring tape. Make a
record on the check form.
2.5.
7
Repeat steps 3, 4, 5 and 6 for the Reference Points 7, 5, 4, 3, 2, 10 and 13 (left and right sides).
2.5.
8
Measure the dimension A, left and right from RP 12 on top surface of wing to RP 10 on the horizontal
stabilizer. Make a record on the check form.
2.5.
9
Measure the dimensions B, left and right, from RP 12 to RP 8 on the upper leading edge of the vertical
stabilizer. Make a record on the check form.
2.5.
10
Measure the dimensions C, left and right, from RP 12 to RP 13 on the side of the rear fuselage. Make a
record on the check form.
2.6 Engine Alignment Check
Refer to Fig. 1 thru Fig. 3 .
Note
The propeller blade measure point is to be taken from the center of the blade at a radius of 1 meter.
2.6.
1
Select one propeller blade as the master blade.
2.6.
2
Position the master blade horizontally.
2.6.
3
Measure the dimension D on the left hand side, master propeller blade to the start of the fuselage skin (75
mm (3 in) forward of frame 10). Make a record on the check form.
2.6.
4
Turn the master blade through 180° so that the blade is horizontal.
2.6.
5
Measure the dimension D on the right hand side (master propeller blade to the start of the fuselage skin).
Make a record on the check form.
