## Discrepancy

DURING INSPECTION OF IMPULSE COUPLING, I.E., AD 78-09-07R3, NUT WAS LOOSE DUE TO CRACK IN BORE OF IMPULSE COUPLING.  TCM BENDIX SB 639 REFERS TO INSTALLATION OF COUPLINGS.  AD 78-09-07R3 DOES NOT REQUIRE REMOVAL OF COUPLING FOR INSPECTION.  MAYBE IT SHOULD TO DETECT CRACKS IN BORE OF COUPLING.  BOTH MAGS AND IMPULSES REPLACED WITH REBUILT TCM UNITS.
