China Airlines Flight 358 was a Boeing 747-2R7F freighter plane that crashed on December 29, 1991 shortly after takeoff from Chiang Kai-shek International Airport in Taipei, Taiwan. The aircraft was a 747, registration B-198, that had been in service for 11 years, 3 months. The aircraft had clocked a total of 45,868 hours of flight time during its time in service. The last A-check maintenance had occurred on December 21, 1991, and the aircraft had accumulated 74 hours of flight time since that point.
Several minutes after takeoff, the crew reported problems with the #2 engine, prompting Taipei air traffic control (ATC) to vector the flight into a left turn to return to the airport. Approximately two minutes later, the crew reported that they were unable to turn left, and ATC approved a right-hand turn instead. This was the last radio contact made by the crew. The crew lost control of the airplane and it struck a hill, right wing first, near Wanli, Taipei. The crash occurred at approximately 3:05 PM, at an altitude of 700 feet. All five crewmembers died in the crash, and there were no injuries on the ground.
The subsequent investigation revealed that the #3 engine and its pylon had separated from the airplane and struck the #4 engine, breaking it off the wing as well. A more detailed investigation revealed that the pylon midspar fittings, which attach the pylon to the lower portion of the wing front spar, had failed. The search for the #3 engine and its pylon, which landed in the sea, took several months. Subsequently, Boeing recalled every 747 in use for pylon modifications.
The aircraft was the same one involved in the China Airlines Flight 334 hijacking on May 3, 1986.
