Boeing Co. and U.S. regulators exercised too little quality control over subcontractors during development of the 787 Dreamliner, according to a federal report that made seven recommendations to bolster such oversight.

The 787 is safe, meets design standards and is about as reliable as other Boeing jetliners were after being introduced, the Federal Aviation Administration said in a review following lithium-ion battery failures in planes flown by Japan Airlines Co. and ANA Holdings Inc. that led to a grounding of the Dreamliner for three months last year.
