Circumstances:
At approximately 800 feet down the left side of the runway the left engine experienced a power loss. The aircraft swerved off the left side of the runway colliding with a drainage ditch and coming to rest inverted. Examination of the fuel control unit revealed that the bellows within the assembly were found in an extended position, indicating a leak into the evacuated area. A failure was noted at the seam in the bellows. In addition, examination of the propeller revealed that the start locks were engaged and the blades were at the start lock position at impact. In order to engage the start locks, the power lever has to be moved to reverse during shutdown with the engine rpm below 50%. After engine start the pilot must again retard the power levers to reverse to disengage the start locks. The locks will not disengage after the power lever is set to the flight range.
Probable cause:
Occurrence #1: loss of engine power(partial) - mechanical failure/malfunction
Phase of operation: takeoff - roll/run
Findings
1. (c) fuel system,fuel control - failure,partial
2. (c) fuel system,fuel control - leak
3. (c) propeller system/accessories - engaged
4. (c) propeller - improper use of - pilot in command
5. (c) performance data - not identified - pilot in command

Aircraft flight hours:

Circumstances:
During the weather briefing the pilot was advised that VFR flight was not recommended due to low ceilings and poor visibility. The pilot responded he had to go to Fort Payne VFR because they have no instrument approach. A Jeppesen US (lo) 29 low alt enroute chart was found at the wreckage that had a line drawn traversing southwest out of the Chattanooga VOR between V-115 and V-115e. The MEA for these airways was 4,000 ft msl. Prior to departure the pilot as advised that tops were reported 4,500 ft with another layer at 9,000 ft. The pilot responded he was going to Fort Payne and they had no approach there. Approximately 2-1/2 min after takeoff the pilot reported "...looks like about 1500 is all we're gonna get right now." About 7 min later the pilot reported they were still VFR but might want to turn around. The aircraft impacted the top of a north/south ridge line at an elevation of 2,020 feet. The copilot was part of the company's management team. A passenger was seriously injured while six other occupants were killed.
Probable cause:
Occurrence #1: in flight collision with terrain/water
Phase of operation: cruise
Findings
1. (f) preflight planning/preparation - inaccurate - pilot in command
2. (f) weather condition - haze/smoke
3. (f) weather condition - low ceiling
4. (f) weather evaluation - misjudged - pilot in command
5. (c) flight into known adverse weather - continued - pilot in command
6. (f) company-induced pressure - company/operator management
7. (f) terrain condition - mountainous/hilly
8. (c) proper altitude - not maintained - pilot in command

Circumstances:
The aircraft was 20 feet agl during landing when the crew heard a propeller go into beta mode and the aircraft yawed to the right. The pilot lost control of the aircraft and it collided with a snow bank which separated the wings from the fuselage. Impact damage made it impossible to tell why the propeller went into beta mode.
Probable cause:
Occurrence #1: airframe/component/system failure/malfunction
Phase of operation: landing - flare/touchdown
Findings
1. (f) propeller system/accessories,pitch change mech - undetermined
2. (f) propeller system/accessories,reversing system - undetermined
3. (f) propeller system/accessories,prop control unit - undetermined
