Shizuo Kambayashi/AP FILE - Boeing said that eight 787 planes must be inspected and repaired before they are allowed to fly, and it contacted the airlines, which removed those planes from service. Boeing declined to identify the airlines involved, but United Airlines, Air Canada and Singapore Airlines confirmed that each has one plane grounded for inspection. Boeing Co. said that it discovered “two distinct manufacturing issues” towards the rear of certain 787s that means the planes don’t meet design standards. Regulators allowed 787s to resume flying after Boeing redesigned the housing around lithium-ion batteries used for auxiliary power systems including the electrical system in the cockpit. Last year, Singapore Airlines grounded two of its 787s after finding that fan blades on some Rolls Royce engines deteriorated faster than expected.
