For those people that do not have the Service Memorandum book:
"In order to measure aileron free play, one aileron should be blocked
in the neutral position and the free play measured at the trailing edge of
the other aileron. In checking the motion, care should be taken not to
exert sufficient force to deflect some of the members, thereby getting a
false reading. (See Service Memorandum No. 56.)
"It is recommended that the aileron system be checked fro free play
after every 100 hours of operation and if measurement exceeds 5/16", all
joints and bearings should be checked and those which are loose should be
tightened or replaced."
