Boeing’s shares slipped on Monday after the US planemaker said it will have to correct a fuselage problem on some of its 787 dreamliners.
The company said it involves delamination — cracking in the lightweight carbon-fibre composite material from which the fuselage is made — but that there are no immediate safety concerns and this would not affect the number of planes it is able to produce.
However some aircraft industry analysts suggested this could disrupt Boeing’s effort to boost its production rate to 10 planes per month by the end of next year.
The 787 is about three years behind its original schedule because of supply chain delays.
It entered service last year and has been a hit with customers. Boeing has taken more than 800 orders for the plane.
All Nippon Airways, the launch customer for the 787, said it had conducted checks and that its aircraft were still operating as normal.
Boeing’s chief rival, Airbus, recently blamed a combination of manufacturing and design flaws for wing cracks on its A380 superjumbo. The company said it had found a simple remedy for the problem, easing concerns among analysts who had feared the problem could dog the European planemaker.
