Another Boeing 787 Dreamliner aircraft suffers fuel leak

The US National Transportation Safety Board begins investigation.

A Boeing 787 Dreamliner aircraft operated by Japan Airlines to Tokyo suffered a fuel leak yesterday at the Boston’s Logan International Airport, severely damaging the aircraft’s auxiliary power unit battery.

A similar incident happened on Monday this week at the same airport.

However, Boeing said that the two incidents happened this week were not related to electrical fires happened earlier on the 787 aircraft, which entered into service in September 2011.

The American aerospace and defence corporation, which is planning to double the production of wide body aircraft in 2013, is facing technical problems with the 787 aircraft.

Massachusetts Port Authority (Massport), which operates Logan airport, told the Financial Times that a Japan Airlines 787 had been taxiing towards the runway at 12.25pm local time when a fuel leak was spotted. The jet returned to the airport gate, where the passengers disembarked. The flight eventually departed just after 4pm.

The US Federal Aviation Administration said: “The FAA is looking into a reported Japan Airlines 787 fuel leak at Logan airport [on Tuesday] and continues to look into the cause of [the previous] 787 incident at Logan.”

Boeing, in a statement, said: “Nothing that we’ve seen in this case indicates a relationship to any previous 787 power system events, which involved power panel faults elsewhere in the aft electrical equipment bay.”

In December 2012, a United Airlines 787 flying from Houston to New York had to divert to New Orleans due to a faulty generator, while a Qatar Airways 787 was also grounded with a similar problem.

A large part of the 787 aircraft is produced from carbon fibre reinforced plastic instead of traditional aluminium to reduce weight.

Meanwhile, Boeing’s shares declined a further 2.63 per cent on Tuesday trading.
