## Probable cause

AN INADVERTENT STALL DURING INITIAL CLIMB. A FACTOR WAS: IMPROPER ROTATION SPEED FOR TAKEOFF.

## Sequence of events

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

- Loss of control - in flight, takeoff - initial climb
  - lift-off - premature, pilot in command (contributing factor)
  - stall - inadvertent, pilot in command (cause)
- In flight collision with terrain/water, descent - uncontrolled

## Analysis

DURING TAKEOFF ROLL, THE PILOT ROTATED AT 60 MPH UTILIZING 10 DEGREES OF FLAPS.  THIS SPEED IS THE STALL SPEED OF THE AIRCRAFT IN THAT CONFIGURATION AT MAXIMUM GROSS WEIGHT.  THE AIRCRAFT CLIMBED TO APPROXIMATELY 100 FEET, NOSED OVER, AND DOVE INTO THE GROUND, AS OBSERVED BY TOWER CONTROLLERS.  THE PILOT STATED THAT HE CLIMBED TO ABOUT 100 FEET WHERE HE 'FELT' A LOSS OF POWER AND ELECTED TO LAND ON REMAINING RUNWAY. THE MANUFACTURER REPORTED THAT WHEN OPERATING AT SUCH SLOW SPEED, THE PROPELLER WILL LOAD RESULTING IN LOWER RPM.

## FAA reports on this event (1)

The FAA's own accident and incident reports, matched to the aircraft by N-number and date (OpenAirDocs).

From the NTSB's public API. Aircraft are matched to registry aircraft by N-number and event date, checked against the reported serial number, make and model; the registry's history has gaps, so older matches can be wrong. Compare the reported make and model.
