## Probable cause

A LOSS OF ENGINE POWER DUE TO CARBURETOR ICE. THE LACK OF SUITABLE TERRAIN FOR THE FORCED LANDING WAS A FACTOR.

## Sequence of events

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

- Loss of engine power(total) - nonmechanical, takeoff - initial climb
  - weather condition - carburetor icing conditions (cause)
- Forced landing, descent - emergency
- In flight collision with object, descent - emergency
  - object - tree(s)
  - object - residence
  - terrain condition - none suitable
- In flight collision with terrain/water, descent - uncontrolled

## Analysis

THE PILOT STATED THE AIRPLANE AND ENGINE SEEMED TO OPERATE NORMALLY DURING A BRIEF LOCAL FLIGHT.  HE RETURNED TO THE HOME BASE AIRPORT AND PERFORMED A TOUCH AND GO.  DURING THE INITIAL CLIMB THE PILOT NOTICED A DECREASED RATE OF CLIMB AND ENGINE RPM.  THE PILOT BELIEVED IT WAS TOO LATE TO PUT THE AIRPLANE BACK DOWN ON THE RUNWAY, SO HE TRIED TO 'MILK IT AROUND' TO LAND.  THE AIRPLANE BEGAN A GRADUAL DESCENT INTO TREES AND A HOUSE BEFORE IT CAME TO REST ON A ROAD IN A RESIDENTIAL AREA.  POST-ACCIDENT EXAMINATION REVEALED NO EVIDENCE OF PRE-IMPACT MECHANICAL MALFUNCTION. THE PILOT STATED HE BELIEVED CARBURETOR ICING MAY HAVE CAUSED THE LOSS OF ENGINE POWER.  THE TEMPERATURE/DEWPOINT PROVIDED BY THE PILOT WERE NOTED ON A CARBURETOR ICING PROBABILITY CHART.  THE RESULT INDICATED A PROBABILITY FOR MODERATE ICING AT CRUISE POWER/SERIOUS ICING AT GLIDE POWER.

## 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 19920626021969A](https://openairdocs.org/incident/19920626021969A), Jun 26, 1992: Amtrqk QUICKIE2, South St Paul, MN, Substantial damage. Surging engine on climbout. Descended. Struck trees and a roof. No engine defects. Pilot believes carburetor icing.

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.
