## Discrepancy

(CAN) AIRCRAFT ON HELISKIING WHEN THIS OCCURRED. INSPECTED IAW AD96-156-071(B) R1 PART 1.1, EVERY 30 HOURS OR 150 CYCLES. THIS WAS BEING INSPECTED DUE TO THE CYCLES EVERY 2 OR 3 DAYS.  THE CROSSBEAM WAS FOUND SMOKING IN THE REGION OF SUSPECTED CRACK.  THE AREA WAS CLEANED, INSPECTED AND FOUND TO BE SERVICEABLE.  AFTER A NEXT DAY FLYING IT WAS INSPECTED AGAIN AND FOUND TO BE SMOKING AGAIN REMOVED FROM SERVICE TO BE NDT.  SENT TO A NDT AMO AND CRACK WAS CONFIRMED. THE AD IS WORKING.
