## Discrepancy

NR 1 ENGINE THRUST REVERSER WOULD NOT STOW AFTER LANDING.  CREW RECYCLED THE NR 1 REVERSER LEVER AND THE ENGINE COMPRESSOR STALLED.  EGT PEAKED AT 550C FOR 2 TO 3 SECONDS AND THE ENGINE WAS SHUT DOWN.  MAINTENANCE INSPECTED ENGINE INLET, EXHAUST, AND BLEED SYSTEM WITH NO TROUBLE FOUND.  THE NR 1 ENGINE THRUST REVERSER WAS PLACED ON MEL 78-1.  EGT WAS WITHIN LIMITS.  PART CAUSING PROBLEM TO BE  DETERMINED.
