## Probable cause

FAILURE TO USE CARBURETOR HEAT.

## Sequence of events

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

- Loss of engine power(partial) - nonmechanical, approach - vfr pattern - final approach
  - weather condition - carburetor icing conditions
  - carburetor heat - not used, pilot in command (cause)
- Forced landing, descent - emergency
- Roll over, landing - roll

## Analysis

THE CFI STATED THAT DURING THE DOWNWIND LEG, HE WAS EXPLAINING A MANEUVER TO A STUDENT WHILE SIMULTANEOUSLY REDUCING THROTTLE & LOWERING COLLECTIVE. HE DID NOT APPLY CARBURETOR HEAT. THE TURN TO BASE WAS SLOW & AFTER REALIZING THAT THE FLT WOULD NOT LAND AT THE PLANNED TOUCHDOWN POINT, THE CFI APPLIED POWER TO GO-AROUND BUT THE ENG WAS SLOW TO RESPOND. DURING THE RUN-ON LANDING, THE HELICOPTER ROLLED OVER AFTER COLLIDING WITH A DIRT MOUND. THE ENG & ITS SYSTEMS WERE EXAMINED BY AN FAA AIRWORTHINESS INSPECTOR WHO REPORTED THAT THERE WAS NO FAILURE OR MALFUNCTION. ACCORDING TO THE ICING PROBABILITY CHART USING TEMP & DEW POINT TAKEN AT AN ARPT 12 NM SE OF THE ACCIDENT SITE 10 MINUTES BEFORE THE ACCIDENT, CONDITIONS WERE FAVORABLE FOR VISIBLE ICING AT GLIDE & CRUISE 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 19901003046569A](https://openairdocs.org/incident/19901003046569A), Oct 3, 1990: Robsin R22BETA, Miami, FL, Substantial damage. Engine lost power on practice autorotation. Made power off run landing short and rolled. Did not use carb heat.

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.
