On 19 Feb 1985 it was at FL410 over the Pacific Ocean on its way from Taipei to LA, when it lost power on engine nr.4. After disconnecting the autopilot it went into an uncontrolled dive, made a full 360 degrees aileron roll, and became supersonic for a short time. It recovered at 9000 feet. In the process it lost 11 feet of the left stabilizer, the whole elevator and 5 feet from the right stabiliser, also the APU separated from its mount. It was repaired, seen here 8 years later.
