According to a report in the New York Times, the two airlines operating the largest number of 787 Dreamliners, All Nippon Airways and Japan Airlines, had experienced battery problems before the two incidents that caused the grounding.
The commitment from Singapore Airlines marks a fresh vote of confidence for the 787 after the aircraft was plagued earlier this year by overheating problems with its lithium-ion batteries, resulting in a four-month grounding of the 50 787-8 jets in world-wide service.
