Aviation Accident Summary CHI90FA019

CLARE, MI, USA

Aircraft #1

N8805A

BEECH B35

Analysis

DURING THE INITIAL CLIMB PHASE OF FLIGHT, THE AIRCRAFT WAS OBSERVED TO HAVE A DECREASE OF ENGINE POWER FOLLOWED BY A DECELERATION OF THE AIRCRAFT WITH A NOSE HIGH ALTITUDE. THIS WAS FOLLOWED BY A DEPARTURE FROM CONTROLLED FLIGHT AND IMPACT WITH THE TERRAIN. THE AIRCRAFT WAS DESTROYED BY IMPACT WITH THE TERRAIN AND POST-IMPACT FIRE. THE PILOT SUSTAINED FATAL INJURIES. SUBSEQUENT INVESTIGATION REVEALED THAT THE FUEL SELECTOR WAS CENTERED BETWEEN THE RIGHT AND OFF POSITIONS. DURING TESTING, LITTLE AIRFLOW WAS POSSIBLE THROUGH BOTH THE RIGHT AND LEFT INLETS TO THE OUTLET, THROUGH THE VALVE.

Probable Cause and Findings

IMPROPER PREFLIGHT BY THE PILOT BY NOT ASSURING THAT THE FUEL SELECTOR WAS PROPERLY POSITIONED, WHICH RESULTED IN FUEL STARVATION, AND THE PILOT'S FAILURE TO MAINTAIN AIRSPEED, WHICH RESULTED IN A STALL/SPIN.
