## Discrepancy

LOST BOTH PACKS, FLIGHT DIVERTED.  FOUND AIR LEAK AT RT WING LEADING EDGE, AT THE DUCT CONNECTION BETWEEN TRACK 2 AND 3.  THERE WAS EVIDENCE OF BURN MARKS AT JOINT. REPLACED 4 SEALS FROM PNEUMATIC DUCTING LEADING TO AFT OF NR 1 PYLON HEAT EXCHANGER.  REPLACED 2 SEALS FROM RT WING ANTI-ICE DUCTING ABOVE NR 1 PYLON MAIN PNEUMATIC DUCTING.   REPLACED WING LOOP ELEMENTS 38HF, 74HF, 42HF, 69HF, 75HF, 43HF, AND 70HF.  DUE TO CHRONIC HISTORY CONCERNING RT WING LEAK ECAM WITH BLEED SYS 2 & PACK 2 FAULTS IN FLT,  AIRCRAFT CHECKS GOOD.
