Contact Air has identified the twin-jet as being registered D-AFKE. The aircraft had been newly delivered to Contact Air in the last few weeks.
"Despite repeated attempts by the cockpit crew, the main landing-gear could not be extended," says the German carrier.

"According to initial reports are landing no passengers were injured," says the carrier, adding that the jet had been transporting 73 passengers and five crew members.
