Détails:
Flight 564 departed Miami, Florida, at 16:20 with its destination Newark, and with stops scheduled at Tampa, Atlanta, and Washington, D.C. The flight progressed according to its flight plan to Atlanta, where a landing was made at 19:43. Because of low ceilings and visibility forecast for Washington it was agreed that Flight 564 would be cleared from Atlanta to Newark, subject to possible reclearance en route in the event the weather at Washington was suitable for a landing. The flight departed Atlanta at 20:27 and proceeded on an instrument flight plan at 7,000 feet along Airway Green 6. Nearing Washington, the crew obtained permission to approach the National Airport. At 23:16 the flight reported that It had missed its approach and requested clearance for a second approach. While maneuvering for another approach, the DC-4 struck the crest of a low ridge at an elevation 200 feet above sea level, 6 miles south-southwest of Washington National Airport. The aircraft progressed upslope, continued in a turn for approximately 500 feet during which time the landing gear failed and the right wing began to disintegrate as it struck and demolished two telephone poles in its path. As it passed over the top of the ridge and started down the northern slope, the aircraft momentarily left the ground making contact again on the left wing and causing the wing to break outboard of the No. 1 engine. Pivoting on the left inboard wing panel, the aircraft rolled into an Inverted position and skidded tail first to a stop.

The DC-4 struck a ridge while on approach. The aircraft burned out after all occupants had deplaned.


PROBABLE CAUSE: "The Board finds that the probable cause of this accident was the failure of the pilot to maintain flight at or above the minimum safe altitude for instrument approach to Washington National Airport."
