Circumstances:
The airline transport pilot was landing a retractable landing gear-equipped turboprop airplane on a 10,900 foot long, by 150 foot wide paved runway. According to the pilot, while on approach to land, he selected 10 degrees of wing flaps, and then selected the landing gear selector switch to the down position, which was followed by "three greens", indicating the landing gear was down, locked, and safe for landing. He said that after touchdown, during the initial landing roll, the landing gear retracted, and the airplane slid on the underside of the fuselage. The airplane veered to the right of the runway centerline, and the right wing collided with numerous runway edge lights. A post crash fire ensued when the right wing's fuel tank was breached. The airplane received structural damage to the underside of the fuselage, and the right wing was destroyed. Propeller strike marks originated in the vicinity of the accident airplane's touchdown point, and extended to the airplane's final resting point, about 2,200 feet from initial contact. A postaccident inspection of the airplane by the IIC and another NTSB air safety investigator, disclosed no evidence of any pre accident mechanical malfunction of the landing gear assembly or its associated operating systems. The airplane was placed on jack stands and hydraulic pressure was supplied to the airplane's hydraulic system using a hydraulic ground power unit. The airplane's landing gear retraction system was cycled numerous times, with no mechanical anomalies noted.
Probable cause:
The pilot's failure to lower the airplane's landing gear during landing, which resulted in an inadvertent wheels up landing.

Circumstances:
While cruising unde VFR mode in poor weather conditions, the pilot lost control of the seaplane that entered a dive and crashed in flames in an isolated area located in the region of Cordova. SAR operations were initiated but eventually suspended as no trace of the aircraft nor the three occupants was found. The wreckage was eventually localized on May 21, 1979.
Probable cause:
Uncontrolled descent and ground collision after the pilot initiated flight in adverse weather conditions. The following contributing factors were reported:
- Continued VFR flight in adverse weather conditions,
- Low ceiling,
- Fog,
- Snow,
- Icing conditions.

Probable cause:
Descended into mountain on approach after the pilot failed to follow the approved procedures. The following contributing factors were reported:
- Improper IFR operation,
- Low ceiling,
- High obstructions,
- Failed to execute published instrument approach.

Circumstances:
Pacific Northern Flight 201 failed to maintain its intended track after taking off from Cordova, Alaska, bound for Anchorage, Alaska. Mt. Gilbert is approximately 28 nautical miles to the right of the flight's first intended checkpoint and is 9,646 feet in elevation. At an altitude of 9,000 feet, crashed into the sheer face of Mt. Gilbert, killing all nine passengers and five crew members.
Probable cause:
The Board determines that the probable cause of this accident was the failure of the crew to use all available navigational aids in establishing the aircraft's position on Amber I Airway, thereby allowing the aircraft to deviate from course and fly over hazardous terrain. A contributing factor was the failure of Air Defense Radar, which had been tracking the aircraft, to notify either ARTCC or the crew that the aircraft was proceeding on a dangerous course.
