## Discrepancy

AIRCRAFT RETURNED TO PLATFORM DUE TO DURING START RT ENG IGNITION FAILED WITHOUT EGT.  PERFORMED REVISION TO IGNITION SYS IAW AMM 74-21-01, DETECTING RT IGNITION FAILED, SO THE RT ENG IGNITION WAS ENABLED IAW AMM 74-21-01 & LT ENG IGNITION WAS OUT OF SERVICE & DEFERRED IAW MEL 74-1-2-B CAT  B.  DURING TRANSIT CHECK, THE LT IGNITION LEAD WAS REPLACED IAW AMM 74-21-02.  TESTED CORRECT & THE REPORT WAS CLOSED.
