Austrian regional carrier InterSky has extended its engine MRO agreement with Lufthansa Technik Aero Alzey for a further five years.
The Bregenz-headquartered airline operates three Pratt & Whitney PW123-powered Bombardier Q300 turboprops from its base at Friedrichshafen, Germany.
When the original contract was inked in July 2010, InterSky had four aircraft. The fleet size was reduced earlier in February 2012, but meantime the airline is planning to introduce again a fourth turboprop later this year, and add further aircraft in 2013.
It is not clear, however, what type will be employed in future. The company's founder, Renate Moser, told Flightglobal in February that it could take the ATR 72-600.
LHT says that the original long-term contract was prematurely extended.
