From the FAA’s Accident/Incident Data System (AIDS), through its Aviation Safety Information Portal, as reported. The NTSB investigates accidents separately, and its record of an accident is the fuller one. The aircraft is matched to the registry by N-number and event date, checked against the reported make and model; the registry’s history has gaps, so older matches can be wrong. Compare the reported make and model.

What happened

The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.

(-23) Pilot lost control of the aircraft during landing. (.4)the airline transport certificated pilot was landing a twin-engine turboprop airplane at a remote airport on a scheduled air taxi flight. Rising hilly terrain is located east of the airport. The pilot said that during the approach for landing, he noticed the airport wind sock indicating a wind from the east about 25 knots. When the pilot descended to 500 feet, about mid-base, the airplane encountered moderate turbulence and an increased rate of descent. He added engine power to arrest the descent. As he turned toward the runway, the airplane encountered 3 to 4 rolling oscillations with a bank angle up to 90 degrees while descending toward the runway. According to a company mechanic who traveled to the scene, it appeared that the airplane struck the runway about 1,200 feet from the approach end with the left wing and left elevator, while yawed about 45 degrees to the left of the runway centerline. The airplane then slid off the left side of the runway. After the collision, the pilot evacuated the passengers, and noticed the airport wind sock was indicating a tailwind. The airport/facility director y contains the following in the airport remarks: 'unattended. Easterly winds may cause severe turbulence in vicinity of runway.'

(-23) PILOT LOST CONTROL OF THE AIRCRAFT DURING LANDING. (.4)THE AIRLINE TRANSPORT CERTIFICATED PILOT WAS LANDING A TWIN-ENGINE TURBOPROP AIRPLANE AT A REMOTE AIRPORT ON A SCHEDULED AIR TAXI FLIGHT. RISING HILLY TERRAIN IS LOCATED EAST OF THE AIRPORT. THE PILOT SAID THAT DURING THE APPROACH FOR LANDING, HE NOTICED THE AIRPORT WIND SOCK INDICATING A WIND FROM THE EAST ABOUT 25 KNOTS. WHEN THE PILOT DESCENDED TO 500 FEET, ABOUT MID-BASE, THE AIRPLANE ENCOUNTERED MODERATE TURBULENCE AND AN INCREASED RATE OF DESCENT. HE ADDED ENGINE POWER TO ARREST THE DESCENT. AS HE TURNED TOWARD THE RUNWAY, THE AIRPLANE ENCOUNTERED 3 TO 4 ROLLING OSCILLATIONS WITH A BANK ANGLE UP TO 90 DEGREES WHILE DESCENDING TOWARD THE RUNWAY. ACCORDING TO A COMPANY MECHANIC WHO TRAVELED TO THE SCENE, IT APPEARED THAT THE AIRPLANE STRUCK THE RUNWAY ABOUT 1,200 FEET FROM THE APPROACH END WITH THE LEFT WING AND LEFT ELEVATOR, WHILE YAWED ABOUT 45 DEGREES TO THE LEFT OF THE RUNWAY CENTERLINE. THE AIRPLANE THEN SLID OFF THE LEFT SIDE OF THE RUNWAY. AFTER THE COLLISION, THE PILOT EVACUATED THE PASSENGERS, AND NOTICED THE AIRPORT WIND SOCK WAS INDICATING A TAILWIND. THE AIRPORT/FACILITY DIRECTOR Y CONTAINS THE FOLLOWING IN THE AIRPORT REMARKS: 'UNATTENDED. EASTERLY WINDS MAY CAUSE SEVERE TURBULENCE IN VICINITY OF RUNWAY.'
