More Problems for Boeings 787 Dreamliners

Thomson clients air frustration over expected Dreamliner delay
A delay in delivery of Thomson Airways’ first Boeing 787 appears inevitable, with the Dreamliner grounded and investigators in the US and Japan unable to identify the cause of batteries overheating on two aircraft.
Thomson has said it had no details of any revised delivery dates, while Boeing is expected to issue fresh guidance today (Wednesday).
The carrier was due to receive its first Dreamliner in February and to start flying the aircraft on May 1.
Thomson clients expressed frustration at the lack of information, amid fears that they won’t fly on the 787 despite booking and paying a small premium.
David Stacey, who describes himself as “a long-time customer of Thomson” told Travel Weekly: “Thomson needs to offer customers the chance to switch or stick. It’s unfair.”
A spokesman for the airline said: “At the current time, Thomson Airways has not received any communication from Boeing regarding changes to delivery dates. Therefore we cannot comment on speculation of delays. Normal booking conditions apply for customers who wish to amend or cancel their holiday.”
Boeing said: “It is impossible to put a timetable on it. We have hundreds of experts working around the clock.”
A Boeing spokesman told Travel Weekly: “We are producing aircraft, but we’re not going to be delivering any 787s until the Federal Aviation Administration (FAA) approves measures to meet its air-worthiness directive.”
Investigations are under way in the US and Japan following a fire on a Japan Airlines 787 at Boston and an emergency landing in Japan by an ANA 787 when its main battery overheated. Both incidents involved new lithium-ion batteries used on the 787 as part of its innovative power system.
Officials in Japan ruled out a problem with the battery maker this week, while US regulators said they had made “no significant discoveries” since the aircraft was grounded in mid-January.
With attention shifting to the 787’s electrical system, analysts warned the grounding could be prolonged.
ANA replaced Dreamliner batteries 10 times before problems emerged

Launch customer All Nippon Airways repeatedly replaced batteries on Boeing 787 Dreamliners even before overheating problems emerged, according to a report overnight.
The disclosure prompted the US National Transportation Safety Board to call for Boeing to provide a full operating history of the lithium-ion batteries used on the grounded aircraft, according to the Associated Press.
The regulator made the call after becoming aware of battery problems at ANA that occurred before a battery fire in a 787 parked at Boston airport on January 7. Boeing has already collected some of the information, a spokesman said.
ANA said it had replaced batteries on its 787 aircraft some 10 times because they failed to charge properly or showed other problems, and informed Boeing about the swaps.
Japan Airlines also said it had replaced 787 batteries. It described the number involved as a few.
All 50 787s in service around the world remain grounded after an ANA flight made an emergency landing in Japan when its main battery overheated two weeks ago.
ANA spokeswoman Megumi Tezuka was quoted as saying the airline was not required to report the battery replacements to Japan's transport ministry because they did not interfere with flights and did not raise safety concerns.
Having to replace batteries on aircraft is not uncommon and was not considered out of the ordinary, she said.
Japanese and U.S. investigators looking into the 787's battery problems shifted their attention this week from the battery-maker to the manufacturer of a monitoring system. That company makes a system that monitors voltage, charging and temperature of the lithium-ion batteries.
The NTSB said yesterday that it was conducting a chemical analysis of internal short-circuiting and thermal damage of the battery that caught fire in Boston.
