Boeing reports wing cracks on 787 Dreamliners still in production

NEW YORK, March 7 Fri Mar 7, 2014 4:44pm EST

NEW YORK, March 7 (Reuters) - Boeing Co said on Friday that "hairline cracks" had been discovered in the wings of 787 Dreamliner jets still in production, a condition that could delay deliveries of some jets but will not affect its 2014 guidance on overall deliveries for the year.

Boeing said wing maker Mitsubishi Heavy Industries Ltd notified it of the problem, which arose after a change in the manufacturing process. The cracks in shear ties on wing ribs in the 787 affects about 40 planes and the fix will take one to two weeks per plane. "We are confident that the condition does not exist in the in-service fleet," Boeing added.

I am becoming increasingly convinced that the Boeing 787 Dreamliner is having so many design problems and quality failures due to the fact that Boeing for the first time outsourced so much of the work to Japanese companies (GS Yuasa for batteries and Mitsubishi Heavy for wings, among others). Japanese quality is not what it used to be, yet peoples’ perceptions have not yet caught up with this reality.

I find it interesting that the defective wings for the Boeing 787 Dreamilner were made by Mitsubishi Heavy Industries.

The U.S. Nuclear Regulatory Commission has also accused Mitsubishi Heavy Industries of designing and building defective generators for the San Onofre nuclear plant in Southern California. The nuclear power plant was permanently shut down last year as a result of these problems, and the California utility Edison is suing Mistubishi Heavy Industries for damages relating to the shut down.
