 FORWARD side of the support beam and the adjacent bushing face on the spar support fitting.
 NOTE: This clearance FORWARD of the support beam
____ cannot be more than 0.020-inch.
 b)  If the clearance between the bushing faces FORWARD of the support beam is MORE than 0.020-inch, replace the defective bushings.
 NOTE: The defective bushings can possibly be on the
