The Boeing Company (NYSE:BA) has discovered hairline fractures in the wings of yet-to-be-delivered 787 aircraft, resulting in more delays that could put the manufacturer’s target delivery dates in jeopardy.
This is the most recent in a string of setbacks for the Chicago-based aerospace giant, which has just managed to get production of the Dreamliner boosted to 10 per month after years of delays. According to the Boeing, a change in manufacturing by a Japanese supplier Mitsubishi Heavy Industries Ltd (TYO:7011) is responsible for the fractures. Further inspections have discovered problems in other jets.
This most recent problem comes after worries with the aircraft’s lithium-ion batteries and complaints from employees at Boeing's Everett, Wash., factory that workers at the new Charleston, S.C., plant were delivering unfinished fuselages.
The worldwide manufacturing process of the 787 has been often controversial and the reason, many industry insiders claim, for the many problems discovered. This was underlined at the Dubai Air Show in 2013 when the CEO of Emirates Airline said that he would prefer that the 777X aircraft, the most recent from Boeing, be built in one location to avoid problems similar to those experienced by the 787.
Here’s a timeline of problems the Dreamliner has experienced over the last five years.
