Report: Boeing to Inspect 787s for Wing Cracks

Seattle, WA -- Boeing says a manufacturing problem has caused hairline cracks in some of its 787 Dreamliner wings, leading to inspections of 42 airplanes and delaying some deliveries, The Wall Street Journal reported Friday.

A Boeing spokesman said the wingmaker, Mitsubishi Heavy Industries Ltd., told Boeing that its manufacturing process may have caused hairline cracks in the wings it produces on soon-to-be-delivered jets.

Following inspections revealed cracks on some jets, said the spokesman.

Boeing said none of the 123 787s delivered so far are affected by the issue, reported The Wall Street Journal. A person familiar with the inspections said Mitsubishi told Boeing about the issue in the second half of February after its routine quality checks.

Boeing expects each airplane will take one to two weeks to inspect and correct any cracks found.

Boeing and its partner are inspecting 787s with line numbers running from 151 to 193, about a fifth of all Dreamliners built since 2007, according to the same person familiar with the issue.

Mitsubishi builds the entire fiber composite 787 wing at its Nagoya, Japan, factory before its shipped to Boeing's final assembly lines in Everett, Wash., and North Charleston, S.C.

About 17 of the 42 airplanes are fully completed and seven have undergone pre-delivery flight tests; rest are in various states of assembly.

The issue is the latest hurdle for Boeing, which aims to produce 10 Dreamliners a month this year.
