What happened
The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.
(-23) Only the pilot in command has been interviewed at this time. The aircraft entered a left downwind for landing on runway 35 at Wales, AK. The wind appeared to be gusting from about 010. The aircraft touched down in the first 1/3 of the runway and began "weather vaning" left and right. Although the pilot at the controls used brakes and reverse thrust the aircraft stopped just past the runway end lights. The right propeller contacted a hard snow berm and the blades were damaged. On further inspection it was found that the engine was also damaged where the power section attaches to the gas generator section. The aircraft is sitting on the ramp at Wales, awaiting the arrival of a new engine. Primary factor for loss of control is yet to be determined. Amendment to follow. privacy data omitted (-23 Amendment) after interviewing the entire crew and people on the ground at the time of the incident it has been determined that the main contributing factor to the loss of control, was a windshift of 180 degrees after the pilot landed on the runway. The winds at the closest reporting station, tin city, which is about six miles to the east, were from the southeast at 36 knots gusting to 44 knots. Also contributing was the temperature of 1 degree celsius which caused a very slick surface on the runway which was covered with compacted snow and ice. The position of the runway to the surrounding terrain makes Wales susceptible to this type of weather phenomena. Winds from an easterly direction area influenced by a mountain just east of the runway and can change direction on the runway with little variance in the direction of the prevailing wind.
As the FAA filed it
(-23) ONLY THE PILOT IN COMMAND HAS BEEN INTERVIEWED AT THIS TIME. THE AIRCRAFT ENTERED A LEFT DOWNWIND FOR LANDING ON RUNWAY 35 AT WALES, AK. THE WIND APPEARED TO BE GUSTING FROM ABOUT 010. THE AIRCRAFT TOUCHED DOWN IN THE FIRST 1/3 OF THE RUNWAY AND BEGAN "WEATHER VANING" LEFT AND RIGHT. ALTHOUGH THE PILOT AT THE CONTROLS USED BRAKES AND REVERSE THRUST THE AIRCRAFT STOPPED JUST PAST THE RUNWAY END LIGHTS. THE RIGHT PROPELLER CONTACTED A HARD SNOW BERM AND THE BLADES WERE DAMAGED. ON FURTHER INSPECTION IT WAS FOUND THAT THE ENGINE WAS ALSO DAMAGED WHERE THE POWER SECTION ATTACHES TO THE GAS GENERATOR SECTION. THE AIRCRAFT IS SITTING ON THE RAMP AT WALES, AWAITING THE ARRIVAL OF A NEW ENGINE. PRIMARY FACTOR FOR LOSS OF CONTROL IS YET TO BE DETERMINED. AMENDMENT TO FOLLOW. ^PRIVACY DATA OMITTED^ (-23 AMENDMENT) AFTER INTERVIEWING THE ENTIRE CREW AND PEOPLE ON THE GROUND AT THE TIME OF THE INCIDENT IT HAS BEEN DETERMINED THAT THE MAIN CONTRIBUTING FACTOR TO THE LOSS OF CONTROL, WAS A WINDSHIFT OF 180 DEGREES AFTER THE PILOT LANDED ON THE RUNWAY. THE WINDS AT THE CLOSEST REPORTING STATION, TIN CITY, WHICH IS ABOUT SIX MILES TO THE EAST, WERE FROM THE SOUTHEAST AT 36 KNOTS GUSTING TO 44 KNOTS. ALSO CONTRIBUTING WAS THE TEMPERATURE OF 1 DEGREE CELSIUS WHICH CAUSED A VERY SLICK SURFACE ON THE RUNWAY WHICH WAS COVERED WITH COMPACTED SNOW AND ICE. THE POSITION OF THE RUNWAY TO THE SURROUNDING TERRAIN MAKES WALES SUSCEPTIBLE TO THIS TYPE OF WEATHER PHENOMENA. WINDS FROM AN EASTERLY DIRECTION AREA INFLUENCED BY A MOUNTAIN JUST EAST OF THE RUNWAY AND CAN CHANGE DIRECTION ON THE RUNWAY WITH LITTLE VARIANCE IN THE DIRECTION OF THE PREVAILING WIND.
