Douglas C-49 (DC-3)

While cruising by night under VFR mode, the crew changed his route from 170° to 195° direction Palmdale as they thought flying over the valley. Shortly later, the airplane struck a ridge and crashed down the slope of Mt Whitney (11,770 feet high) located about 12,5 miles west of Lone Pine. SAR operations were quickly conducted but eventually suspended few days later as no trace of the aircraft nor the 35 occupants was found. The wreckage was located in a very hazardous area on August 8, 1969 and was not detectable till this date due to snow accumulation on the ground. The accident was unsurvivable.

Douglas C-47 Skytrain (DC-3)

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.
