TASK INSTRUCTIONS:
1. Check the radial free play of all flap hinges (3 per flap). Total diametrical clearance (from
displaced fully one direction to displaced fully in the opposite direction) in excess of .020
requires replacement of the flap hinge pin.
2. Cycle flaps through all flap settings to ensure system function.
3. Select 0° flap and verify flaps are in line with the center wing trailing edge ±.020”.
4. Select 0° flap position and secure digital level to flap surface with its long axis perpendicular to
flap hinge line.
5. Align flap’s trailing edge to that of the inboard wing by applying hand pressure to the flap if neces-
sary, and then set the Alt Ref function of the level.
6. Pull up on flap trailing edge with light pressure (~2 lb
f
) to remove play. Record the level’s reading
in table below.
7. Select 15° flap position. Pull up on flap trailing edge with a light pressure to remove play. Record
the level reading in table below.
8. Select 30° flap position. Again, pull up on flap trailing edge with a light pressure to remove play.
Record the level reading in table below.
9. Repeat steps 1-8 on other side.
