Circumstances:
The aircraft had an in-flight breakup when the left wing and tail section separated. Post accident inspection revealed a right engine main fuel supply line progressive rupture, only trace amounts of fuel in the fuel lines, and no rotational damage to the right engine. Pre accident, long term, fuel leak evidence surrounded the ruptured line. The right propeller was not feathered. The left wing D-tube rib at station 127 exhibited compressive buckling. Left wing fractures were upward, and horizontal stabilizer deformation was downward. During an actual loss of engine power in the airplane 17 months before this accident, the pilot had feathered the incorrect propeller. Both a mechanic, and an FAA safety counselor, who were familiar with the pilot, described him as able to be disoriented, and reliant on GPS for navigation. He had stated five months before the accident that he did not feel his instrument flying skills were proficient, and desired training. On the day of the accident, weather was visual meteorological conditions, with layered clouds above 2,200 feet mean sea level. The pilot stated to the FAA weather briefer that he wanted to make the flight under visual conditions. The flight route and altitude was unknown.
Probable cause:
The rupture of the right engine fuel supply line as a result of inadequate inspection by the pilot/mechanic, and the pilot's excessive pull up which resulted in exceeding the design stress limits of the airplane. Factors were the improper emergency procedures and failure to feather the propeller.

Circumstances:
Upon touchdown at Bronson Creek Airport, the right main gear collapsed. The right wing struck the runway surface and out of control, the aircraft veered off runway and came to rest in a grassy area. All three occupants escaped with minor injuries while the aircraft was damaged beyond repair.
Probable cause:
It is believed that the bolts attaching the right horizontal gear support to the main wheel failed upon landing.

Aircraft flight hours:
16116
Circumstances:
Prior to departing on a scheduled air taxi flight with two passengers, the pilot obtained a weather briefing that included airmets for mountain obscuration, IFR and icing conditions. VFR flight was not recommended. A company flight that departed before the accident flight, returned to the company base due to low ceilings, after the accident flight departed. The flight departed on a VFR flight plan and encountered low ceilings in the area of mountainous terrain. The pilot began maneuvering around the terrain and during a period of obscuration, collided with several trees. The company operations manual specifies that the pilot is responsible for the conduct of the flight; however, procedures are included that detail the dispatch responsibilities, dissemination of weather information, and the director of operations responsibility to monitor and cancel flights if necessary.
Probable cause:
The pilot's continued visual flight rules (VFR) flight into instrument meteorological conditions (IMC). Factors in the accident were fog and low ceilings, and a failure of the operator to follow their procedures specified in the company operations manual.

Circumstances:
After takeoff from Bronson Creek, while climbing to a height of 800 feet, the crew initiate a left turn when the left wing rolled to an angle of 30°. The aircraft stalled and crashed, bursting into flames. Both occupants were killed. The aircraft was carrying a load of gold.
Probable cause:
It is believed that the aircraft stalled because its speed was too low while completing a turn to the left.

Aircraft flight hours:

Circumstances:
Approximately 3/4 of an hour after departing for Wrangell, Alaska, the pilot of the regularly scheduled commuter flight contacted company dispatch approximately 30 miles from Ketchikan, and reported that he was returning due to weather. Shortly thereafter, the pilot communicated with another company pilot flying in the same vicinity and both pilots described the weather at their respective locations as 'marginal'. Weather conditions at the Ketchikan International Airport (18 nautical miles from the crash site) at the time of the accident were characterized by low ceilings, multiple cloud layers and reduced (3 mile) visibilities with light rain. The aircraft collided with trees/rising terrain at 800 feet msl while in a near level flight path headed east southeast. Right wingtip impact signatures indicated a very shallow right wing down/nose up attitude at the initial tree impacts. All four occupants were killed.
Probable cause:
The pilot's attempting to operate vfr in instrument meteorological conditions. Factors contributing to the accident were upsloping terrain in the aircraft's flight path as well as weather conditions resulting in an obscuration of the terrain.
