## Discrepancy

AIRCRAFT RETURNED TO PLATFORM, AFTER BOTH ENG STARTS, THE RT ENG GEN DID SHUTDOWN.  REVISION DETECTING RT IDG FAILED, SO THE RT IDG WAS DEFERRED IAW MEL 24-1-2 CAT  B.  THE RT IDG WAS REPLACED IAW AMM 24-11-11 & THE AC SYS GEN & APU MODULE P5-4 WAS REPLACED IAW AMM 24-21-59.  TESTED CORRECT & THE REPORT WAS CLOSED.
