## Probable cause

PILOT FACTOR IN THAT HE FAILED TO MAINTAIN FLYING SPEED.

## Sequence of events

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

- Loss of engine power(total) - nonmechanical, cruise
- Forced landing, descent - emergency
- In flight collision with terrain/water, landing

## Analysis

SHORTLY AFTER TAKEOFF AT ABOUT 500 AGL, THE PVT PILOT SAID THAT HE EXPERIENCED A PARTIAL POWER LOSS. AN ATTEMPT TO LAND DOWNWIND ON THE RNWY, JUST DEPARTED, WAS CONSIDERED, BUT THE PLT FELT HE HAD EXCESSIVE ALTITUDE, SO HE FLEW DOWN WIND FOR LANDING ON THE DEPARTURE END. ON FINAL APPROACH, AND LEVELING OFF FOR TOUCH DOWN, THE ACFT SUDDENLY PITCHED NOSE DOWN AND COLLIDED WITH THE TERRAIN, SHORT OF THE RUNWAY. THE ACFT SKIDDED ABOUT 50 YARDS, NOSE DOWN BEFORE COMING TO REST. THE AIRPORTS PROXIMITY TO THE LAKE, THE TIME OF DAY, AND METEOROLOGICAL CONDITIONS WERE CONDUCIVE FOR CARBURETOR ICING AT THE TIME OF THE ACCIDENT.

## FAA reports on this event (1)

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

- [Accident 19900417010129A](https://openairdocs.org/incident/19900417010129A), Apr 17, 1990: Cessna 150G, Two Harbors, MN, Substantial damage. Power loss on climbout, turned back but too high. Tried for departure runway but stalled on final short of runway.

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.
