- Loss of engine power(partial) - nonmechanical, approach
  - weather condition - temperature extremes (contributing factor)
  - fluid,fuel - ice (contributing factor)
  - fuel system,filter - blocked(total) (contributing factor)
  - fluid,fuel - starvation (contributing factor)
  - emergency procedure - performed, pilot in command
  - acft/equip,inadequate aircraft manuals, manufacturer (contributing factor)
- Loss of engine power(total) - mech failure/malf, approach - vfr pattern - final approach
  - reason for occurrence undetermined (cause)
  - fluid,fuel - other
  - turbine assembly - overtemperature
  - aircraft performance,two or more engines - inoperative
- Forced landing, landing - flare/touchdown

## Analysis

THE ACFT WAS ON A SCHEDULED FLT FROM ANCHORAGE TO COLD BAY, AK WITH INTERMEDIATE STOPS AT KING SALMON & DUTCH HARBOR, AK. EN ROUTE BETWEEN ANCHORAGE & KING SALMON, THE AIR TEMPS AT CRUISE ALTITUDE WERE BETWEEN -36 & -40 DEG FAHRENHEIT. WHILE ENTERING DONWND TO LND AT KING SALMON, THE BEFORE-LNDG CHECK WAS MADE WHICH INCLUDED TURNING OFF THE FUEL HEATERS.SHORTLY THEREAFTER, THE R ENGINE LOST PWR & WOULD NOT RESTART. THE R ENGINE WAS FEATHERED & SECURED. SOON AFTER THAT, WHILE TURNING TO FINAL APCH WITH THE GEAR DOWN, THE L ENGINE BEGAN LOSING PWR. THE CAPTAIN ELECTED TO LAND ON A FRZN RIVER & CALLED FOR THE GEAR TO BE RETRACTED. WHILE LNDG, THE ACFT TOUCHED DOWN BEFORE THE GEAR WAS FULLY RETRACTED. AN INVESTIGATION REVEALED ALL 3 TURBINE STAGES OF THE L ENGINE WERE DAMAGED FROM OVERHEATING, INDICATIVE TO EXCESS FUEL FLOW. EXCEPT FOR THE L ENGINE OVERHEATING, NO OTHER MECHANICAL DEFECTS WERE FOUND WITH EITHER ENGINE. HOWEVER, ENTRAINEDWATER (WTR IN SOLUTION) CAN OCCUR IN JET FUEL. WATER (29 TO 150 PPM) WAS FOUND IN FUEL SAMPLES. CONDS FOR ICE, PRESENT.

## 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 19820216002259A](https://openairdocs.org/incident/19820216002259A), Feb 16, 1982: Nihon YS11A600, King Salmon, AK, Substantial damage. Power loss and engine fire on approach. Elected to land on a frozen river.

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.
