Circumstances:
A Wien Consolidated Airlines Fairchild F-27B, N4905, crashed at Pedro Bay, Alaska. The 36 passengers and three crew members were killed in the accident and the aircraft was destroyed by in-flight breakup and ground impact. The aircraft was being operated as Flight 55 in scheduled domestic passenger service between Anchorage International Airport, AK (ANC) and Dillingham Municipal Airport, AK (DLG) with en route stops at Iliamna Airport, AK (ILI), Big Mountain Airport, AK (BMX), and King Salmon Airport, AK (AKN). Flight 55 departed from Anchorage at 08:46 on an instrument flight plan for Iliamna. The flight was cleared to cruise at 16,000 feet. The weather at Iliamna was reported to be clear, and the visibility was 15 miles at the time of the flight's departure from Anchorage. The flight proceeded toward Iliamna without reported difficulty, and at 09:25, the first officer requested a clearance for an approach to Iliamna. This request was approved. No further communication was received from the crew. Ground witnesses in and around the Pedro Bay area reported that they saw a fireball and a large cloud of black smoke which appeared to be behind the wing of the aircraft. The aircraft appeared to continue on course for a short period of time, then pieces of the aircraft were seen falling, and the aircraft entered a spinning descent. The major portion of the wreckage was located on the southern shore of Foxies Lake at an elevation of approximately 220 feet.
Probable cause:
The Board determines that the probable cause of this accident was an in-flight structural failure caused by an encounter with severe to extreme turbulence. This turbulence was not forecast and its presence was not known to the flight crew. The failure occurred in an area of the right wing (WS 197) which had been weakened to an indeterminate degree by pre-existing fatigue cracks.

- Failure of the right engine for undetermined reason,
- Improper operation of flight controls,
- Improper operation of powerplant,
- Improper emergency procedures,
- Inadequate preflight preparation,
- Improperly loaded aircraft-weight and CofG,

The accident was probably caused by the combination of the following factors:
- Engine failure or malfunction caused by carbon deposit, ignition system, spark plugs,
- Stall during initial climb,
- The pilot attempted operation with known deficiencies in equipment,
- The pilot failed to abort the takeoff procedure,
- The pilot failed to obtain/maintain flying speed,
- Witnesses stated that the right engine backfired,
- The pilot continued the takeoff procedure and climbed in a steep attitude,
- Two previous takeoff were aborted.

Circumstances:
The crew was engaged in a cargo flight and the aircraft was carrying a load of cement bags. En route, the right engine failed and the crew decided to divert to Golovin Airport for an emergency landing. On final, the pilot-in-command decided to make a go-around when the airplane stalled and crashed in a lagoon located short of runway and came to rest in three feet of water. Both pilots were uninjured while the aircraft was damaged beyond repair and abandoned.
Probable cause:
Failure of the cylinder number one on right engine. Initiated go-around at a too low speed, causing the aircraft to stall and crash. The following factors were considered as contributing:
- The crew failed to maintain flying speed,
- The crew misused or failed to use flaps,
- Poorly planned approach.

Circumstances:
Following an uneventful flight, the crew completed the landing procedure on a snow covered runway at Sitka Airport. After touchdown, the airplane went out of control, veered off runway and collided with a rock pile. While all three occupants escaped uninjured, the aircraft was destroyed by a post crash fire. The aircraft was owned by Fred Lewis and Fred Zax.
Probable cause:
The crew failed to maintain directional control after landing due to snow on runway. The crew decided to attempt the flight with known deficiencies in equipment as the aircraft was poorly equipped with unreliable radios and the cockpit light failed in flight. At the time of the accident, the runway was covered with one inch of snow.

Circumstances:
The crew was completing a transpacific flight from Sangley Point AFB to Whidbey Island with probable en route stops in Japan and Alaska (Elmendorf or Ladd AAF). While in cruising altitude, the airplane struck the slope of Mt Fairweather located approximately 123 miles northwest of Juneau. As the aircraft failed to arrive at Whidbey Island NAS, SAR operations were conducted but eventually suspended few days later as no trace of the aircraft nor the 14 crew members was found. In 1982, the wreckage was found in an isolated area.
Probable cause:
Controlled flight into terrain.
