Circumstances:
On July 29, 2006, about 1345 central daylight time, a de Havilland DHC-6-100, N203E, registered to Adventure Aviation, LLC, and operated by Skydive Quantum Leap as a local parachute operations flight, crashed into trees and terrain after takeoff from Sullivan Regional Airport (UUV), near Sullivan, Missouri. The pilot and five parachutists were killed, and two parachutists were seriously injured. The flight was operated under 14 Code of Federal Regulations (CFR) Part 91 with no flight plan filed. Visual meteorological conditions prevailed. According to photographic evidence provided by a witness, the pilot taxied the airplane onto runway 24 from the intersecting taxiway, which is about 1,700 feet from the runway’s west end, and began a takeoff roll to the west from that location, rather than using the runway’s entire 4,500-foot length. Photographic evidence depicting the airport windsock shows that the airplane departed into a moderate headwind. Witnesses at the airport reported seeing the airplane take off and climb to about treetop height. Several witnesses reported hearing a “poof” or “bang” noise and seeing flames and smoke coming from the right engine. One witness reported that, after the noise and the emergence of flames, the right propeller was “just barely turning.” Photographic evidence shows that, at one point after the flames occurred, the airplane was about one wingspan (about 65 feet) above the runway. One witness estimated that the airplane climbed to about 150 feet. Witnesses reported that the airplane lost some altitude, regained it, and then continued to fly low above the treetops before turning to the right and disappearing from their view behind the tree line. Another witness in the backyard of a residence northwest of the airport reported that she saw the airplane flying straight and level but very low over the trees before it dived nose first to the ground. She and her father called 911, and she said that local emergency medical service personnel arrived within minutes. The airplane impacted trees and terrain and came to rest vertically, nose down against a tree behind a residence about 1/2 mile northwest of the end of runway 24.
Probable cause:
The pilot’s failure to maintain airspeed following a loss of power in the right engine due to the fracturing of compressor turbine blades for undetermined reasons. Contributing to some parachutists’ injuries was the lack of a more effective restraint system on the airplane.
Final Report:

Crash of a De Havilland DHC-6 Twin Otter 300 in Jumla: 9 killed

Circumstances:
The twin engine aircraft departed Nepālganj Airport on a domestic service to Jumla with an intermediate stop in Surkhet, carrying six passengers, three crew members and a load consisting of bags containing grains for a total of 941 kilos. While approaching Jumla Airport, the crew was informed that runway 27 was in use with a wind from 240 at 4 knots. For unknown reasons, the captain started the approach to runway 09 at 1201LT. At an excessive speed, he missed the runway, initiated a go-around procedure and passed to the right of the tower. Then, he started a steep turn to the left when the aircraft lost height and speed and crashed in a field located 500 meters east of the airport, bursting into flames. The aircraft was totally destroyed by impact forces and a post crash fire and all 9 occupants were killed.
Probable cause:
The crew's attempt to make a sudden go-around while close to runway 09 threshold with a very low circuit altitude and subsequent attempt to turn in a tight circuit with excessive angle of bank that led to a stall. The aircraft subsequently contacted terrain due to insufficient clearance available for effective stall recovery. The quick decisions to change runway added to the crew workload at a critical period which was aggravated by the breakdown of cockpit discipline. The other contributory factors leading to the accident were:
- Violation of company Standard Operating Procedures by flight crew,
- Insufficient monitoring of its flight training program and line operations by Yeti management,
- Inadequate oversight of Yeti Airlines by CAAN.

Circumstances:
Following an uneventful flight from San José-Tobías Bolaños Airport, the crew started the descent to Tamarindo Airport runway 07. On short final, at a height of about 500 feet, control was lost and the aircraft crashed in a wooded area located 2 km short of runway. All eight occupants were injured while the aircraft was destroyed.
Probable cause:
The accident was the consequence of a loss of control on short final following the combination of the following factors:
- An elevator cable probably broke away due to a progressive wear combined with a damaged pulley,
- The proximity of the terrain,
- The low speed of the aircraft,
- The lack of crew training in such situation,
- The loss of control of the aircraft occurred at a critical phase of the flight, initially caused by a mechanical failure and later to human factors.

Aircraft flight hours:

Circumstances:
The purpose of the flight was for the second pilot to perform an evaluation of the first pilot, who was recently designated by the operator as a backup pilot. Following several successful flights with and without passengers, the pilots discussed single engine operations, and the first pilot reduced the right engine's power to flight idle and feathered the propeller. During the final leg of the approach to landing, the airplane crossed over a fence near the runway threshold, and the first pilot pitched the airplane downward. The nose landing gear contacted the runway "hard," and the airplane began to bounce. After several bounces, the first pilot elected to abort the landing, increased power on the left engine to "full." As the first pilot pitched the airplane upward, it yawed to the right, "stalled," and impacted the ground.
Probable cause:
The pilot's improper flare and recovery from a bounced landing, which resulted in a stall and subsequent impact with the ground.
