4. Model 182 Series Wing Twist Check Procedure
A. Mark Wing Station Reference Points (Refer to Figure 602)
(1) Locate WS 39.00. Make a mark, with a felt tip pen, approximately 0.50inch aft of lateral row of
rivets in wing leading edge spar flange.
(2) Locate WS 100.50. Make a mark, with a felt tip pen, approximately 0.50 inch aft of lateral row
of rivets in wing leading edge spar flange.
(3) Locate outboard WS 207.00. Make a mark, with a felt tip pen, approximately 0.50 inch aft of
lateral row of rivets in wing leading edge spar flange.
B. Measure Wing Twist at Each Wing Station (Refer to Figure 602)
NOTE: While performing the following procedure, stay as far away as possible from the "canned"
areas of the wing.
(1) At WS 39.00:
(a) Grind bolt "A" to a dimension of 2.00 inches. Grind bolt "B" to a dimension of 1.00 inch.
Place these bolts 29.50 inches from each other on the upper edge of the straightedge and
secure using tape.
(b) Secure protractor to bottom of the straightedge.
(c) Hold straightedge parallel to wing station and place bolt "A" on mark.
(d) Set bubble in protractor to center, and lock protractor to hold this reading.
(2) At WS 100.50:
(a) Hold straightedge parallel to wing station.
(b) Place bolt "A" on mark, set protractor head against lower edge of straightedge and verify
bubble in protractor head indicates level.
(3) At WS 207.00:
(a) Remove bolt "A" from straightedge. Grind another bolt "A" to a dimension of 0.45 inch.
Place this bolt 24.00 inches from bolt "B" and secure to straightedge.
(b) Hold straightedge parallel to wing station and place bolt "A" on mark.
(c) Check to assure that protractor bubble is still centered. If proper twist is present, the
protractor readings will be the same (parallel).
NOTE: Forward or aft bolt may be lowered from wing 0.10 inch (maximum) to attain
level indication.
