## Discrepancy

DURING PATIENT TRANSFER FLIGHT FROM OUTLYING HOSPITAL TO MAIN HOSPITAL, FUEL FUMES NOTED BY ALL CABIN OCCUPANTS. VENTS AND HEATER DUCTS MANIPULATED WITH NO DISCERNABLE EFFECT. SMELL OF FUEL FUMES INCREASED IN INTENSITY TO UNPLEASANT LEVELS UPON REDUCTION OF COLLECTIVE DURING APPROACH TO LANDING PHASE. SUBSEQUENT INVESTIGATION BY DUTY MECHANIC REVEALED FAULTY HMU.  MECHANIC FOUND FUEL LEAKING INTO ENGINE FROM THE P2 SENSE LINE.
