Circumstances:
According to the FAA specialist on duty at the Nome flight service station the pilot of Munz Northern flight 601 requested only the Ambler weather at 0030 gmt. The only surviving passenger stated that the flight departed Nome, AK at 1330 bst and as the flight continued north she could only see straight down and was nervous because the ground was so close. She further stated that the props changed their sound which related to the sound they made earlier in the flight when the aircraft climbed to clear a mountain. She also added that they were in whiteout conditions prior to impact and there were no mechanical irregularities that she was aware of. The pilot and a passenger were killed.
Probable cause:
Occurrence #1: in flight encounter with weather
Phase of operation: cruise
Findings
1. (f) weather forecast - not obtained - pilot in command
2. (f) weather condition - whiteout
3. (c) VFR flight into IMC - inadvertent - pilot in command
4. (f) weather condition - snow
5. (c) VFR flight into IMC - continued - pilot in command

Circumstances:
14 seconds after liftoff from runway 10 at Poti Airport, while climbing to a height of 60 meters at a speed of 195 km/h, both engines lost 60% of power. While the power on the left engine increased to 94,5% 11 seconds later, the power on the right engine dropped to zero. The crew elected to feather the right propeller but this was not possible. The airplane lost height, started a descent and slightly turned to the right when, at a speed of 130 km/h, it struck 20 meters high trees and crashed in a wooded area located 450 meters past the runway end. Two pilots and four passengers were killed while 12 other occupants were injured. The aircraft was destroyed.
Probable cause:
It was determined that the malfunction of the right engine was the consequence of a short-term failure of the rotor speed regulator, which forced the crew to shut down the engine and to feather the propeller. For unknown reasons, the propeller could not be feathered, causing drag that reduced the aircraft's speed and necessitating an emergency landing.

Circumstances:
The approach to Quelimane Airport was initiated by night. On final, the pilot-in-command reduced engine power to idle. At a height of 230 feet, as the airspeed dropped below the speed reference, the stick shaker activated. The captain increased engine power when the aircraft lost height and descended until it struck the ground about 400 meters short of runway. The undercarriage were torn off and the airplane slid for few dozen meters before coming to rest. All 110 occupants evacuated safely while the aircraft was damaged beyond repair.
Probable cause:
Wrong approach configuration on part of the flying crew who misjudged speed, distance and altitude on final approach. The crew failed to properly use the Visual Approach Slope Indicators which was considered as a contributing factor.

Circumstances:
Following an uneventful flight from Sapporo, the crew started the descent to Nakashibetsu Airport in marginal weather conditions. On final, while completing a last turn to the left at an angle of 30°, the aircraft struck the ground and crash landed in a snow covered field (40 cm deep snow). It slid for few dozen meters and came to rest 100 meters short of runway 23 threshold, broken in two. 31 occupants were injured and 22 other occupants escaped uninjured.
Probable cause:
The pilot-in-command misjudged altitude and distance while completing the approach in low ceiling. Improper control of the engine power was a contributing factor.

Circumstances:
On approach to Barquisimeto Airport, the crew encountered foggy conditions with limited visibility. On short final, the airplane descended below the glide until it struck the ground 1,015 meters short of runway threshold. On impact, the undercarriages were torn off and the airplane slid on its belly until it came to rest on the runway threshold, broken in two. A crew member and 22 passengers were killed while 27 other occupants were injured.
Probable cause:
Wrong approach configuration on part of the crew who led the aircraft passing below the glide until impact with the ground. The following contributing factors were reported:
- Failure of the crew to initiate a go-around,
- Improper in-flight decisions,
- Inadequate supervision of the flight,
- Lack of visibility due to fog.

Circumstances:
After departure from Tarinkot (Urozgan) Airport bound for Kabul, weather conditions deteriorated. The crew decided to climb to an altitude of 18,500 feet under VFR mode. While flying in poor weather conditions, the crew lost control of the airplane that crashed on the slope of a mountain located in Shashgow Ghazni. All 19 occupants were killed.
Probable cause:
Loss of control after the crew continued under VFR mode in adverse weather conditions. It was also determined that the crew suffered physical impairment due to a lack of oxygen while flying at high altitude.

Aircraft flight hours:

Circumstances:
The aircraft was ditched in the Atlantic Ocean following engine failure. The pilot estimated fuel on board during pre-flight from the electronic fuel gauges. The aircraft flew two hours and 16 minutes before the engines quit in a mode of fuel exhaustion with surging prior to stopping. Post accident investigation using fuel slips revealed a fuel burn within 10 to 15 gallons of fuel exhaustion. The fuel gauges failed on the last leg of the flight and the passengers stated the pilot paid a lot of attention to these gauges. The pilot wanted to divert to Freeport but did not because the weather was below minimums. After ditching the aircraft sank in 800 feet of water. All three occupants were rescued.
Probable cause:
Occurrence #1: loss of engine power(total) - non mechanical
Phase of operation: cruise - normal
Findings
1. (f) fluid,fuel - exhaustion
2. (c) fuel supply - misjudged - pilot in command
3. (f) engine instruments,fuel quantity gauge - erratic
4. (c) refueling - not possible - pilot in command
5. (c) fuel consumption calculations - inaccurate - pilot in command
6. (c) procedures/directives - improper - pilot in command
7. (c) preflight planning/preparation - inadequate - pilot in command
