Circumstances:
During the takeoff roll witnesses observed the aircraft swerve from left to right with the engine(s) 'missing' or intermittent. The aircraft lifted off and climbed to approximately 50 feet agl and continued across a waterway in a left turn with the landing gear extended. The aircraft pitched up and rolled left wing down into the water. Examination of the engines revealed a cracked coil in the left magneto of the right engine. No other mechanical malfunction/failure could be determined. The pilot, sole on board, was killed.
Probable cause:
Occurrence #1: loss of engine power
Phase of operation: takeoff - roll/run
Findings
1. 1 engine
2. (f) ignition system, ignition coil - cracked
----------
Occurrence #2: loss of control - in flight

Circumstances:
The aircraft overflew the destination due to fog. The station manager stated that after transmitting to the pilot that the weather was 'zero zero', the pilot stated that he would continue on to Red Devil and she heard it fly overhead. The first pieces of aircraft debris were found 9 miles south of crooked creek along the western shore of the Kuskokwin River at a point where it widened and the surface of the water smoothed out. No impact marks were found along either shore of the river. Other pilots in the area stated that the fog was down to the ground and extended approx 12 miles south of Crooked Creek. The engine, pilot's seat, and aircraft were not recovered.
Probable cause:
Occurrence #1: loss of control - in flight

Circumstances:
The left engine failed during initial climb immediately after liftoff. Airspeed could not be maintained with one engine out due to the fact that the aircraft was climbing slowly just above the surface and was loaded to 3,809 pounds above its maximum allowable takeoff gross weight. An emergency landing was attempted but directional control was lost and the aircraft stall/mushed and collided with the terrain alongside the runway. The left eng was examined after the accident and no malfunctions found. Both pilots escaped uninjured.

Aircraft flight hours:

Circumstances:
Aircraft was destroyed when it struck power lines and the ground during a single engine go-around. Following a left engine shut down due to severe vibrations, the pilot overflew one airport to return to his home base. En route, he elected not to go to full power due to a 3 minutes limitation he did not want to exceed. The pilot overshot the runway while manually extending the nose gear and elected to attempt a right 270° turn to return to final while at 100-150 feet agl. Nose landing did not extend due to hydraulic pump being on left engine and no pressure. During the turn, the pilot lost control and the aircraft struck the wires. Investigation revealed that one of the blade pitch change links on the left prop had disconnected, allowing one blade to free float. The link pin assembly had backed out as a result of the safety screw backing out due to damaged and stripped threads and an improper length screw being installed. Props had 1/4' safety screws installed instead of 3/8'.
Probable cause:
Occurrence #1: airframe/component/system failure/malfunction
Phase of operation: cruise - normal
Findings
1. (c) propeller system/accessories, pitch change mech - disconnected
2. Propeller feathering - not possible
3. (c) propeller system/accessories, pitch change mech - stripped thread

Circumstances:
The pilot landed downwind on his private strip. The exact amount of the tailwind could not be determined. A thunderstorm was located just to the east of the runway and could have readily given N448 a strong tailwind. The aircraft touched down 390 feet beyond the threshold. Light braking action was evident from that point up to a point 400 feet from a hangar where all tire marks disappeared. The aircraft collided with the hangar, which was built at the end of and across the runway, approximately 10 feet above the runway surface and was destroyed by the subsequent post crash fire. The passenger was seriously injured and the pilot was killed.
Probable cause:
Occurrence #1: in flight collision with object
Phase of operation: landing - aborted
Findings
1. (f) object - building (nonresidential)
2. (c) brakes (normal) - improper use of - pilot in command
3. (f) aborted landing - delayed - pilot in command

Circumstances:
The pilot began taking off from a downward sloping, 2,300 feet runway in light winds. The reported temperature was 92°; the density altitude was about 2,500 feet. The pilot reported the aircraft accelerated normally to V1 speed; however, it hit the tops of trees about 350 to 500 feet beyond the runway, then struck the ground after traveling about another 1,000 feet. Performance charts showed the aircraft would have needed a takeoff distance of 2,200 feet to clear a 50 feet obstacle in calm wind. The pilot reported the wind was from 010° at 3 to 5 knots. A witness reported a 3 to 5 knot tailwind. No preimpact part failure or malfunction was found.
Probable cause:
Occurrence #1: in flight collision with object
Phase of operation: takeoff - initial climb
Findings
1. (c) preflight planning/preparation - inadequate - pilot in command
2. (f) weather condition - high density altitude
3. (f) weather condition - unfavorable wind

Circumstances:
On initial climb the pilot reported 'just lost one', followed by a loss of control and descent into a residential area.

Probable cause:
The NTSB determines the probable cause(s) of this accident to be:
Failure of maintenance personnel to perform proper installation of the left throttle linkage.

Aircraft flight hours:

Circumstances:
While on an instrument flight plan in IMC, the flight was cleared for an instrument approach to the South Lake Tahoe Airport, the intended destination. The aircraft departed the initial approach fix on the published transition to the final approach course. Radar contact was lost at 11,400 feet. Afterward, the aircraft was observed descending out of clouds and maneuvering erratically in VMC until it impacted terrain with no apparent attempt to recover. Medical records revealed pilot had a history of hypertension, hyperlipidemia, and recent loss of 41 pounds on a rigid weight loss program. The autopsy revealed severe arteriosclerosis. Medical records indicated the pilot had been taking diazide intermittently for several years. Post-accident tox results were negative. The circumstances of the accident, in combination with the pilot's severe diet, medical history, and postmortem examination results support the conclusion that the pilot became incapacitated in flight. All four occupants were killed.
Probable cause:
Occurrence #1: loss of control - in flight
Phase of operation: approach - iaf to faf/outer marker (ifr)
Findings
1. (c) incapacitation(other cardiovascular) - pilot in command
