Aircraft flight hours:

Circumstances:
The DC-3 was cruising at FL115 between Burbank and Hawthorne when a no. 2 engine failure forced the crew to shut the engine down and feathered the propeller. At 20:50 EDT the crew radioed Tonopah, NV and said they wanted to make an emergency landing there. At 20:58 EDT the no. 1 engine lost power. The propeller couldn't be feathered and an emergency glide was initiated towards Mud Lake airfield. A 2000 feet/min rate of descent was necessary to maintain a 110 knots airspeed. All electrical and hydraulic power was lost during the descent. The DC-3 struck the ground in a 10-20 degree nose down attitude during the flareout and overturned. It appeared that there were numerous maintenance irregularities, a.o. improperly adjusted valve clearances, improperly adjusted voltage regulators and improperly installed cylinders. The plane was equipped with 2 28V dc generators and one 12V battery. All electrical components other than the starters were designed for 12V dc operation. It also appeared that all maintenance was performed by companies other than the operator. In many instances inadequate and incomplete records failed to reflect work accomplished.
Probable cause:
In flight failure of both engines caused by a fatigue failure on the right engine No.12 cylinder and failure of the left front master rod bearing, necessitating a night emergency landing on unlighted terrain. Inadequate maintenance and inspection.

Circumstances:
The pilot, sole on board, was involved in a local test flight. Shortly after takeoff from Kankakee-Greater Kankakee Airport, while climbing, both engines failed simultaneously. The pilot reduced his altitude and was able to complete an emergency belly landing in a field. The airplane slid for several yards and came to rest. The pilot was unhurt while the aircraft was damaged beyond repair.
Probable cause:
Failure of both engines due to a fuel starvation.

Circumstances:
Shortly after takeoff from Cincinnati-Lunken Field Airport, while in initial climb, the pilot informed ATC about the failure of the left engine. He elected to make an emergency landing in a field when control was lost. The airplane crashed in a field located near the runway end. All four occupants were injured and the aircraft was destroyed.
Probable cause:
Failure of malfunction of the left engine during initial climb and stall due to the failure of the ignition system (spark plug). The loss of control was caused by improper emergency procedures and single engine flight procedures.

Aircraft flight hours:
19134
Circumstances:
The DC-7 touched down on runway 05 following an ILS approach. Reverser were applied, but the no. 1 engine reverser didn't respond. The pilot moved the no. 4 throttle to idle. The plane had then reached a rough part of the runway (a 1000 feet area, beginning 2750 feet down the runway). The DC-7 was turning slightly right, but this was corrected with left brake and rudder and left nose wheel steering. Severe vibration then caused the plane to veer sharply right off the runway, causing the nose gear to collapse. It appeared that the nose wheel strut collar had failed from both the left and right sides.
Probable cause:
Improper reversing technique resulting in the use of excessive directional corrective forces during which the aircraft struck an unsuitable runway condition. Unsuitable runway condition, resulting from inadequate runway maintenance. Inadequate supervision by the captain.
