CESSNA 421
WITNESSES REPORTED A NORMAL TAKEOFF AND CLIMB WAS MADE TO AN ALT OF APRX 400 FT AGL AT WHICH TIME ENG PWR CEASED/ DECREASED. THE RT WING THEN DROPPED, THE NOSE AND LT WING ROSE AND THE ACFT ENTERED A NEAR VERTICAL DESCENT TO GROUND IMPACT. POST ACCIDENT EXAM OF THE ENGS AND TURBOCHARGERS FAILED TO DISCLOSE ANY PRE-IMPACT FAILURES. EXAM OF THE PROP GOVENORS DISCLOSED AN RPM SETTING BELOW TAKEOFF OR CLIMB PWR; HOWEVER, EXACT RPM SETTING COULD NOT BE DETERMINED. THE PLT HAD RECENTLY PURCHASED THIS ACFT AND MOST OF HIS MULTI-ENGINE EXPERIENCE WAS IN BEECH BARONS. THE THROTTLE QUADRANT LOCATION OF THE THROTTLE AND PROP CONTROLS ON THE BARON ARE IN THE REVERSE POSITION OF THOSE ON THE C-421. THE PLT ALSO HAD NOT BEEN CHECK OUT IN THE C-421.
