The Executive Yuan's Aviation Safety Council has indicated that the lost craft did not issue any distress calls prior to the accident. Radar showed the plane breaking into four pieces at an altitude of over 30,000 feet, with one of the pieces propelled in the opposite direction of the flight trajectory.
行政院飛安委員會表示，該失事班機的航管通話紀錄一切正常，但根據航機圖顯示，飛機應該是在三萬英尺以上的高空解體成四大塊，其中一塊的飛散方向更與飛機行進方向相反。
