ESCONDIDO, CA, USA
N566B
BEECH A35
THE PILOT WAS CLEARED FOR A CLIMB TO CRUISE AND WAS ADVISED TO MAINTAIN VFR. A POST-ACCIDENT WEATHER STUDY INDICATED THAT HE WOULD HAVE BEEN IN IMC CONDITIONS FROM ABOUT 3000 FEET THROUGH 7500 FEET MSL. AFTER INITIATING A CLIMB ON COURSE, THE PILOT LOST CONTROL OF THE AIRPLANE AT 7100 FEET AND IT ENTERED A RIGHT DESCENDING SPIRAL. DURING THE UNCONTROLLED DESCENT, JUST PRIOR TO GROUND IMPACT, THE OUTER 1/2 OF THE RIGHT WING SEPARATED IN OVERSTRESS. THE NON-INSTRUMENT RATED PILOT HAD LOGGED A TOTAL OF 5 HOURS OF ACTUAL AND 14 HOURS OF HOOD TIME, THE LAST OF WHICH WAS LOGGED 2-1/2 YEARS BEFORE THE ACCIDENT. THE OPERATOR DID NOT HAVE AN INSTRUMENT OR INADVERTENT IMC TRAINING PROGRAM.
SPATIAL DISORIENTATION OF THE PILOT AFTER HE INITIATED FLIGHT INTO IMC CONDITIONS, AND HIS EXCEEDING THE DESIGN STRESS LIMITS OF THE AIRPLANE DURING THE ATTEMPTED RECOVERY. RELATED FACTORS WERE: THE PILOT'S LACK OF TOTAL AND RECENT INSTRUMENT FLIGHT EXPERIENCE, AND THE OPERATOR'S INADEQUATE RECURRENT TRAINING PROGRAM.
