The European Commission in October also opened an investigation into whether Ryanair had benefited from illegal state aid at Germany's Frankfurt-Hahn airport, and this week Italy's competition agency opened a probe against Ryanair's new hand luggage policies.
Ryanair owed €525,000 to the department that it had received in aid when the company operated an Angoulême-London route. It said the passengers were put on another Ryanair flight five hours later.
'This measure was taken as a last resort by the French authorities after several reminders and attempts to recuperate the money failed, ' the DGAC civil aviation body said.
The aircraft was grounded at 6pm on Thursday, November 8, when the bailiff, with a mandate from the conseil départemental presented himself at Bordeaux and took legal control of the aircraft - which had been scheduled to fly to London Stansted - on the tarmac.
"It is unfortunate that the state had to take such action, which led to the inevitable inconvenience of the 149 passengers on board the immobilised plane", the French civil aviation authority said.
'Just because we manage a little airport in Charente it doesn't mean we are not going to defend ourselves'.
French aviation authorities have seized a Ryanair plane bound for London, stranding almost 150 passengers. Ryanair's fleet is made up mainly of Boeing 737-800 aircraft, which have a list price of more than $90 million each.
The stoppages contributed to a 7% fall in profits to €1.2bn (£1.06bn) for the six months to 30 September.
