An Air India Boeing 787 Dreamliner returned to London due to a communications problem, but has since been operational, the carrier said today.
The aircraft’s transponder failed during the flight on Sunday from London to New Delhi.
The Dreamliner was back in operation on Monday after engineers fixed the transponder and there was no immediate safety concern, an airline spokesman told Reuters.
The glitch followed Japan Airlines reporting problems with a battery on a 787 in Tokyo last week.
Scandinavian low-cost carrier Norwegian said on Tuesday that a fuel leak on a Dreamliner caused a flight from Bangkok to Oslo to be delayed by 19 hours.
The 787 has suffered a series of problems since its launch two years ago. Overheating batteries in some aircraft forced the grounding of its worldwide fleet last year. Flights resumed in April 2013.
