What happened
The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.
(-23) Cessna 152 N627PA departed deer valley airport (dvt) at 1426 MST with flight instructor and flight instructor student on board. Flight was a planned spin recover training lesson. Aircraft was discovered by golf course maintenance personnel on a hillside. There were no witnesses to the aircraft in the air or impacting the ground. The initial impact site was located at coordinates north 33 50 534 west 112.25.061, altitude 2113 MSL. Initial impact site showed ground/soil indentation impact nose down with lower cowling/prop, nose tire/gear, both main gear tires, and left wing tip; right wing outer leading edge and tip impacted small tree approximately 38 inches above the ground. Aircraft magnetic heading was 136 degrees on impact. Tall tiedown ring was observed in initial lower cowl impact site. Inspection of surrounding tree/bushes indicated that the aircraft was slightly left wing low with an approximately 20 to 30 degree nose down attitude on initial impact. After initial impact aircraft skidded up the mountain approximately 20 feet then became airborne traveling approximately 60 feet. Aircraft final position coordinates north 33 50 626 west 112 25 053, altitude 2145 MSL. The engine broke away from the fuselage attach point. Right wing spar broke at forward attach point. Left and right wing had indication of severe downward bending and deformation of wing skin panels. Right and left wing main struts left signature marks on bottom of both wing panels. Main cabin indicated several downward impact damage with floor boards broken away from sides. Main cabin area had several crushing with both pilot seats loose from attachments. Both occupants had shoulder and seat belts attached and fastened. Tailcone behind baggage compartment broke away with the exception of lower panel and control cables. Paper work for N627PA weight and balance indicated a takeoff weight of 1662.5 pounds (maximum takeoff weight listed in POH is 1670 pounds) takeoff arm in inches was listed as 33.3 with a moment of 55382.3 (weight and balance envelope for N627PA indicated maximum forward CG of 32.6 to aft of 36.5). Phoenix TRACON radar provided a copy of the radar plot for the time period between takeoff at deer valley airport (dvt) 1426 MST and discovery of aircraft on the ground 1612 MST. Radar plot in the area of accident location had a 1200 transponder squawk. The aircraft on this plot maneuvered around the crash location for several minutes. At 2227 22.4 gmt this 1200 squawk was at 5500 MSL indicating 90 knots, at 2227 31.6 gmt 1200 squawk was indicating 4600 MSL and 80 knots, at 2227 36.2 gmt 1200 squawk was indicating 4100 MSL at 70 knots, at 2227 40.9 gmt 1200 squawk was indicating 3700 MSL and 70 knots, at 2227 45.5 gmt 1200 squawk was indicating 3300 MSL and 50 knots this was the last radar plot on the 1200 squawk. The location for the radar plot and the crash site coincided with each other. There are no additional causal factors at this time.
