## 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.

## Sequence of events

In NTSB's coding before 2008 (https://www.ntsb.gov/GILS/Documents/codman.pdf).

- Loss of engine power(total) - mech failure/malf, takeoff - initial climb
  - reason for occurrence undetermined (cause)
- Forced landing, descent - emergency
- Loss of control - in flight, descent - emergency
  - airspeed - not maintained, pilot in command (cause)
  - stall - inadvertent, pilot in command (cause)
- In flight collision with terrain/water, descent - uncontrolled

## Analysis

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.
