Boeing investigates latest Dreamliner defect

Battery failures alerted Boeing to potential design failures -- and now engine fire safeguards appear to be flawed.

Boeing is investigating the 787 Dreamliner model once more after the discovery of wiring defects.

Yesterday, All Nippon Airways (ANA) and Japan Airlines said they were conducting checks on their Boeing 787 Dreamliner fleets. The carriers both discovered wiring issues within an engine fire extinguisher system, resulting in ANA delaying a flight and Japan Airlines recalling a plane after it took off for Helsinki. ANA also found similar problems in two other Dreamliners.

ANA owns 20 of the luxury aircraft, while Japan Airlines possesses 10 787's.

Boeing is aware of the issue and is investigating the matter. In a statement, the company said:

"The safety of those flying on Boeing aeroplanes is our top priority. We will thoroughly examine this issue and take the appropriate steps."

In addition, U.S. carrier United Airlines found a pinched wire during an inspection of one of its six Dreamliners. As a result, Boeing has requested operators of the 717, 737, 747-400, 767 and 777 to carry out inspections to rule out any additional problems.

Dreamliners were grounded worldwide in January after lithium-ion batteries caught fire, due to the poor design of battery casing. Flights resumed four months later.
