K'il Kun Xidgwangs Daanaay (IATA: YZP, ICAO: CYZP), formerly known as Sandspit Airport, is located 1.5 nautical miles (2.8 km; 1.7 mi) northeast of Sandspit, British Columbia, Canada.

On January 19, 1952, a Douglas DC-4 on Northwest Orient Airlines Flight 324 attempted to land at Sandspit Airport due to a failed engine.

Unable to regain its lost speed and altitude, the aircraft hit the water about 4,500 feet (1,400 m) from the end of the runway.

36 of the 43 passengers and crew aboard died due to hypothermia or drowning.
