Narrative:A NAMC YS-11A passenger plane, JA8764, was destroyed in an accident on Yokotsudake Mountain, Japan. All 64 passengers and 4 crew members were killed.
TOA Domestic flight 63 originated in Sapporo and was approaching Hakodate Airport (HKD) at the time of the crash.
The flight crew mistook a point approximately 5 nautical miles north of the Hakodate NDB as being just over the Hakodate NDB, a navigation aid, and initiated their descent from an estimated altitude of 6,000 ft in an attempt to cross the high station at 2,500 ft by making a single circle. The outbound flight leg was extended westward and because of a strong southwesterly wind, the aircraft drifted further to the north than the crew expected, striking the mountain.
