The chief executive of British Airways owner IAG has defended his new fleet of 787 Dreamliner aircrafts after recent safety issues.
Coverings on both engines were left unlatched after maintenance on the BA plane in last week's Heathrow landing drama according to a report.
A BA jet was forced to make an emergency landing after one engine caught fire and the cowling of the other blew-off.
British Airways engineers are examining a 747 that had to return to Heathrow after experiencing a "minor technical problem" less than three hours into its flight to Hong Kong.
A British Airways spokesman said: "One of our aircraft experienced a minor technical problem and because of that returned to Heathrow as a precaution.
"Nobody was in danger at any point.
"At the moment our engineers are examining the aircraft. The exact nature of the fault is being looked at."
The flight - BA 0025 - had just started on its 12-hour journey when the problem was spotted.
A British Airways spokesperson told ITV News:
A British Airways plane BA25 bound for Hong Kong experienced a minor technical fault and returned to Heathrow where it landed perfectly safely.
We will do everything we can to make sure the passengers get to their destination.
A British Airways flight which was reported to have suffered a problem with its landing gear is reported to have landed at Heathrow airport.
A British Airways flight bound for Hong Kong is returning to Heathrow airport after reports of a technical fault with its landing gear.
The flight took off from the London airport but has spent some time circling the English Channel and is now returning to the UK.
The airline told the BBC that there was a, "technical problem and the flight will be returning to Heathrow."
Willie Walsh - chief of British Airways owner IAG - has said he remains committed to Boeing's new Dreamliner aircraft despite a series of faults.
He said that most new aircraft have "teething problems" but admitted that the grounding of an entire fleet was unusual, adding that social media had contributed to the outcry over the safety of the Dreamliner.
ITV News' Economics Editor Richard Edgar asked whether he was annoyed by the faults:
The chief of International Airlines Group - which owns British Airways - has said he has complete confidence in the Boeing 787 Dreamliner despite a series of faults.
Willie Walsh told me that the string of fires and faults are normal teething problems, which is good seeing as he is buying so many.
International Airlines Group (IAG) - the owners of British Airways - have announced a £29 million loss for the first half of the year.
It compares with a £221 million loss over the same period last year.
The initial report from the AAIB on the emergency landing of BA flight 762 contains serious findings. The industry must act immediately to take the appropriate safety action and ensure that all lessons are learnt from what has happened. Airline passengers have the right to expect to travel safely and it is the responsibility of all involved in aviation to make sure that happens.
– Patrick McLoughlin, Transport Secretary
I would like to thank the AAIB for their hard work in producing the initial report. They must now be allowed to continue with their investigation and when the final report is complete the relevant authorities will need to consider any further action necessary, in line with the recommendations.
