Rudder assembly must be performed on a flat work surface. Assembly on
a warped surface will result in a warped rudder

Clamps will be required in parts of the assembly to hold the rudder flat to
the work surface
•
Wipe all parts down with acetone to remove markings before assembly
•
All parts must have their edges polished smooth before installation to avoid
cracking in service.

All ribs must be straightened. Use fluting pliers at fluted locations. Check
on a flat table. It is also important that the rib flanges are straight. Use
padded pliers to flatten flanges if necessary.
