tcx247k 'Main Battery Fault' 5th/6th June 09
A friend of mine was travelling on tcx247k from London Gatwick to Corfu on the 5th/6th June this year when a couple of hours into the flight the plane turned back to Gatwick due to technical reasons, which he has since found out from the airline was because the aircraft "suffered a fault with the main battery that could not be resolved by the flight crew. The fault had to be resolved by qualified engineers and Corfu does not have the required engineers available. There was little choice but to have the fault resolved in the UK where specialist engineering staff were available."
Would it not have been cheaper and more practical to land at Corfu and have the engineer flown out on the next flight?
I'm just looking for a little insight into this as I have no airline SOP knowledge, or what the consequences of a 'main battery fault' would be.
