Continental Airlines Flight 1713 was a commercial airline flight that crashed while taking off in a snowstorm from Stapleton International Airport in Denver, Colorado, on November 15, 1987. The Douglas DC-9 airliner, operated by Continental Airlines, was making a scheduled flight to Boise, Idaho. Twenty-five passengers and three crew members died in the crash. The National Transportation Safety Board (NTSB) investigation of the accident determined that the most probable cause of the accident was the failure on the part of the pilot in command to have the aircraft deiced a second time before takeoff. Flight 1713 was operated using a 21-year old Douglas DC-9-14, a twin-engined, narrow-body jet airliner with the registration number N626TX. The aircraft was equipped with two Pratt & Whitney JT8D-7B engines.It was originally delivered to Air Canada in May 1966 and sold to Texas International Airlines in 1968, where it served the majority of its service until Texas International was acquired by Continental in 1982. In 21 years of service, it had accumulated over 52,400 flight hours and over 61,800 cycles.
