From the FAA’s Accident/Incident Data System (AIDS), through its Aviation Safety Information Portal, as reported. The NTSB investigates accidents separately, and its record of an accident is the fuller one. The aircraft is matched to the registry by N-number and event date, checked against the reported make and model; the registry’s history has gaps, so older matches can be wrong. Compare the reported make and model.

What happened

The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.

On March 18, 2014, at approximately 10:15 EDT N9432U, a Cessna CE-150-M was destroyed following a collision with terrain while on an instructional flight that originated from Greenwood Municipal Airport (hfy).

The ATP rated instructor pilot received minor injuries and the student received serious injuries. The airplane was registered to joshua edwin groh and was being operated under the provisions of 14 code of federal aviation regulations part 91. Visual meteorlogical conditions prevailed and no flight plan was filed or required.

After completing several maneuveres and while recovering from slow flight, the student started a turn back to the airport. Midway through the turn, he pushed the throttle in to add power and the engine did not respond.

The flight instructor took control of the aircraft, and after evaluation, made a decision to attempt an off-airport landing. As the aircraft was rounding out and starting its flare, the engine regained power causing the aircraft to pitch up and stall. This resulted in a nose down, left wing low impact with the ground.

Prevailing winds at the time of the accident were from the south at 25 knots. The indianapolis temperature/due point/humidity at 0954 was 35/27/72% and at 1049 was 39/30/70%. Utilizing the carburetor ice probability chart indicates the possibility of serious icing at cruise power. Utilizing the ?new? Carburetor ice probability chart and factoring in humidity indicates the possibility of serious icing at any power.

The aircraft was destroyed with damage to both wings, vertical and horizontal stabilizer, airframe, landing gear, engine, and propeller. All control cables demostrated that there was still continuity from the control inputes to all control surfaces. There was visible fuel in both wing tanks and the fuel filter. A check of the engine revealed fuel in the carburetor as well. All other engine components were checked and no indication of mechanical failure was found.

As the FAA filed it

ON MARCH 18, 2014, AT APPROXIMATELY 10:15 EDT N9432U, A CESSNA CE-150-M WAS DESTROYED FOLLOWING A COLLISION WITH TERRAIN WHILE ON AN INSTRUCTIONAL FLIGHT THAT ORIGINATED FROM GREENWOOD MUNICIPAL AIRPORT (HFY).

THE ATP RATED INSTRUCTOR PILOT RECEIVED MINOR INJURIES AND THE STUDENT RECEIVED SERIOUS INJURIES. THE AIRPLANE WAS REGISTERED TO JOSHUA EDWIN GROH AND WAS BEING OPERATED UNDER THE PROVISIONS OF 14 CODE OF FEDERAL AVIATION REGULATIONS PART 91. VISUAL METEORLOGICAL CONDITIONS PREVAILED AND NO FLIGHT PLAN WAS FILED OR REQUIRED.

AFTER COMPLETING SEVERAL MANEUVERES AND WHILE RECOVERING FROM SLOW FLIGHT, THE STUDENT STARTED A TURN BACK TO THE AIRPORT. MIDWAY THROUGH THE TURN, HE PUSHED THE THROTTLE IN TO ADD POWER AND THE ENGINE DID NOT RESPOND.

THE FLIGHT INSTRUCTOR TOOK CONTROL OF THE AIRCRAFT, AND AFTER EVALUATION, MADE A DECISION TO ATTEMPT AN OFF-AIRPORT LANDING. AS THE AIRCRAFT WAS ROUNDING OUT AND STARTING ITS FLARE, THE ENGINE REGAINED POWER CAUSING THE AIRCRAFT TO PITCH UP AND STALL. THIS RESULTED IN A NOSE DOWN, LEFT WING LOW IMPACT WITH THE GROUND.

PREVAILING WINDS AT THE TIME OF THE ACCIDENT WERE FROM THE SOUTH AT 25 KNOTS. THE INDIANAPOLIS TEMPERATURE/DUE POINT/HUMIDITY AT 0954 WAS 35/27/72% AND AT 1049 WAS 39/30/70%. UTILIZING THE CARBURETOR ICE PROBABILITY CHART INDICATES THE POSSIBILITY OF SERIOUS ICING AT CRUISE POWER. UTILIZING THE ?NEW? CARBURETOR ICE PROBABILITY CHART AND FACTORING IN HUMIDITY INDICATES THE POSSIBILITY OF SERIOUS ICING AT ANY POWER.

THE AIRCRAFT WAS DESTROYED WITH DAMAGE TO BOTH WINGS, VERTICAL AND HORIZONTAL STABILIZER, AIRFRAME, LANDING GEAR, ENGINE, AND PROPELLER. ALL CONTROL CABLES DEMOSTRATED THAT THERE WAS STILL CONTINUITY FROM THE CONTROL INPUTES TO ALL CONTROL SURFACES. THERE WAS VISIBLE FUEL IN BOTH WING TANKS AND THE FUEL FILTER. A CHECK OF THE ENGINE REVEALED FUEL IN THE CARBURETOR AS WELL. ALL OTHER ENGINE COMPONENTS WERE CHECKED AND NO INDICATION OF MECHANICAL FAILURE WAS FOUND.
