Neither problem was with the lithium-ion batteries that were overheating and resulted in the Boeing Co. aircraft being grounded for four months. The 787s returned to commercial service last month with their batteries now encased to prevent overheating from spreading.
The All Nippon Airways flight was scheduled to go from Ube to Tokyo's Haneda airport but the right-side engine would not start, airline spokesman Yoichi Uchida said. He said its 141 passengers are taking other flights.
On Tuesday, a Japan Airlines 787 returned to Haneda shortly after takeoff because of a problem in its deicing system.
The system is needed depending on weather conditions, and a malfunction can at times be dangerous, but the jet was not at risk and it returned safely, JAL spokesman Jian Yang said. The flight was en route to Singapore.
