## Analysis

MOMENTARILY AFTER LIFTING OFF, THE PLT HEARD A PRONOUNCED DECREASE IN ENG NOISE & NOTED THAT THE TACHOMETER INDICATION HAD DROPPED TO 1950 RPM. HE ELECTED TO ABORT, BUT WAS UNABLE TO STOP ON THE REMAINING RWY. AFTER DEPARTING THE RWY, THE ACFT HIT AN OBJECT & RAN INTO A RAVINE BEFORE COMING TO REST. AN EXAM OF THE MARVELL SHEBLER CARBURETOR, MODEL MA4SPA, REVEALED A LEAK IN THE GASKET, PN 16-A48. THERE WAS EVIDENCE THAT THIS WOULD RESULT IN PARTIAL FUEL STARVATION.
