Circumstances:
While cruising at an altitude of 2,500 feet , the right engine failed. The crew feathered its propeller when the left engine lost power. The crew reduced his altitude and elected to make an emergency landing when the airplane struck trees and crashed near an icy river. Both pilots were uninjured while the aircraft was damaged beyond repair.
Probable cause:
Failure of the right engine in flight and partial loss of power on left engine caused by fuel contamination. The following factors were reported:
- Improperly serviced aircraft by owner-pilot,
- Fuel contamination-exclusive of water in fuel,
- Water in fuel,
- Failure of right engine in flight, propeller feathered,
- Left engine lost power,
- Sediment found in fuel storage tanks.

Circumstances:
At approximately 10:48 a.m. eastern daylight time on July 2, 1970, Short Brothers & Harland, Ltd., Skyvan Series 3, N21CK, operated by Jetco Aviation, Inc., Washington, D. C., as air taxi cargo flight, Flight 106, crashed during an approach to Washington National Airport. The aircraft was demolished but did not burn. Both cremnembers received fatal injuries. There were no passengers. According to witnesses, the aircraft was first visible to them, through fog and haze, when it was 700 to 800 feet above and about one-half mile out from the threshold of Runway 15. Shortly after the aircraft came into view of the witnesses, it nosed down and rolled left until the wings were nearly vertical. The nose-down angle steepened progressively until it reached 45° or more. The aircraft struck the water of Roaches Run in this attitude, cartwheeled onto the right wingtip and sank in water 12 to 15 feet deep about 1,800 feet north of the threshold of Runway 15. Both pilots were killed.
Probable cause:
The Board determines that the probable cause of this accident was the loss of effective elevator control due to the forward shift of improperly secured cargo when the aircraft was placed in a steep nose-down attitude during a landing approach in reduced visibility conditions.

Circumstances:
The crew was completing a local training mission at Venice-Marco Polo Airport. On approach, the visibility decreased due to foggy conditions and the pilot-in-command continued the descent at a too high speed, causing the airplane to land at an IAS of 100 knots instead of 70 knots as prescribed. Unable to stop within the remaining distance, the airplane overran, lost its undercarriage and plunged into the sea. All three crew members were injured and the aircraft was destroyed as the right wing was torn off.
Probable cause:
Wrong approach configuration.
