It was at around 8:00 am local time on Sunday morning at the Shangi International Airport (Singapore) when the nose landing gear of an Airbus A330-300 Singapore Airlines retracted for reasons still unknown. The aircraft then fell heavily on its nose and a door was torn off. The aircraft, which had arrived a few hours earlier from Shanghai, was empty except for an engineer who was on board at the time of the incident, and who was not injured.
According to the information we obtained from the Air Accident Investigation Bureau of Singapore, the nose gear of the aircraft retracted during a verification operation of that part of the aircraft because an abnormality had been detected. The airline then decided to charter another aircraft for safety measures. An investigation was launched. The passengers took another aircraft to Hong Kong. This type of incident is extremely rare.
