NTSB narrative
DURING INITIAL CLIMB, AT ABOUT 300 FT AGL, THE PLT REPORTED, A TOTAL LOSS OF ENG POWER WAS EXPERIENCED. THE PLT MANEUVERED THE ACFT TOWARD A CLEARING, LOST CONTROL AND COLLIDED WITH LEVEL TERRAIN IN A NOSE LOW ATTITUDE ADJACENT TO A CITY STREET. EXAM OF THE AIRFRAME & ENGINE REVEALED ADEQUATE SOURCES OF WING TANK FUEL, INDUCTION AIR AND IGNITION. THE ENGINE WAS PARTIALLY DISASSEMBLED & NO MECHANICAL MALFUNCTIONS WERE NOTED. A CONTROLLER REPORTED THAT AFTER TAKEOFF THE ACFT CLIMBED TO BETWEEN 250 AND 300 FEET AGL AND HE OBSERVED THE ACFT IN A HIGH NOSE UP PITCH ATTITUDE BEFORE THE LEFT WING DROPPED AND THE ACFT DESCENDED OUT OF VIEW.
Probable cause
**This report was modified on 2/24/2016. Please refer to the public docket for this accident for additional information.**
The pilot's failure to maintain airspeed during an emergency landing following an inflight loss of engine power, resulting in an aerodynamic stall and loss of control and collision with terrain.

- Unreviewed is an editorial label, not an investigation status. API-sourced is not report-checked or human-reviewed. Explicit event totals are used without summing aircraft injury tables; onboard allocation is withheld. Unknown values remain unknown. The operation category is mapped from the NTSB-reported FAR part and has not been reviewed.
- Filled from the NTSB case API where the bulk record had no value: investigation status. Values present in the bulk record are kept.
- The date is the local date, which is the same as the UTC date the NTSB stores.
