Far East Air Transport Flight 103 (1981) — in-flight breakup after decompression

Aircraft and route

The airplane involved was an early-series Boeing 737-200, a short- to medium-range narrow-body jet commonly used on domestic sectors. Flight 103 was operating a routine domestic route connecting northern and southern Taiwan, a sector flown frequently by local carriers at the time.

Sequence of events

Contemporary reports and the accident record indicate a sudden structural failure accompanied by an explosive loss of cabin pressure shortly after the aircraft reached cruise. The fuselage failed and the airframe disintegrated in midair; wreckage was scattered over a wide area beneath the flight path, complicating on-site recovery and reconstruction.

Investigation and contributing factors

Investigators identified explosive decompression as the immediate event that precipitated in-flight breakup. The official inquiry examined maintenance logs, repair history, structural condition, and potential mechanisms such as metal fatigue, corrosion or faulty repairs that can lead to sudden skin or frame failure. Because the breakup was rapid and extensive, determining a single definitive root cause was challenging; investigations therefore emphasized probable contributing factors rather than a single, narrowly defined failure mode.

Aftermath and safety significance

The accident highlighted the importance of rigorous inspection and maintenance practices for aging airframes. It reinforced attention to inspection intervals, detection of hidden corrosion or fatigue, and standards for structural repairs. Safety authorities and operators reviewed procedures aimed at reducing the risk of catastrophic decompression on older jet types.
