## Discrepancy

CLIMBING THROUGH 15000' AGL HEARD A  LOUD BOOM ACCOMPANIED BY AN ACFT SHUTTER.  IMMEDIATELY, SMELLED A SLIGHT SMOKEY ODOR, WHICH  WENT AWAY AFTER 10 SECONDS.  RETURNED TO AIRPORT FOR AN UNEVENTFUL LANDING. ALL ENGINE PARAMETERS AND FLT CHARACTERISTICS SEEMED NORMAL.  PERFORMED A PREMLIMINARY ENGINE RUN AT GATE AND PERFORMED A MAX POWER ASSURANCE CHECK,  RAN BOTH ENGINES FOR COMPARISON WITH PACKS ON, NO NOTICABLE ODOR.  PARAMETERS WERE WITHIN RANGE ON BOTH ENGINES.  ACFT OK FOR SERVICE.
