Aircraft involved

N6613A Beech A36 None

Probable cause & findings

THE PILOT DELAYED REMEDIAL ACTION WHEN THE IMMINENT LOSS OF ELECTRICAL POWER WAS OBSERVED. ADDITIONALLY, THE PILOT'S FAILURE TO EXECUTE THE APPROPRIATE EMERGENCY PROCEDURE AND MANUALLY LOWER THE LANDING GEAR, RESULTED IN ITS COLLAPSE UPON LANDING. CONTRIBUTING TO THE ACCIDENT WAS THE PILOT'S LACK OF KNOWLEDGE REGARDING THE POWER SOURCE FOR THE AIRPLANE INSTRUMENTATION. WHEN CONFRONTED WITH THE ZERO OIL PRESSURE INDICATION THE PILOT'S SELF INDUCED PRESSURE PRECIPITATED AN UNNECESSARY HURRIED LANDING.
