Sequence of events
NTSB’s coding before 2008: each occurrence and phase of flight, and the causes and factors under it. The codes are defined in NTSB’s coding manual.
Analysis
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.
