Spanish charter specialist Helitt Lineas Aereas had one of its ATR 72 aircraft seized by a court order on 18 October.
The aircraft (MSN 428) was grounded at Trapani airport in Italy during aircraft crew maintenance and insurance (ACMI) operations for Swiss regional carrier Darwin Airline.
The Swiss carrier issued its own statement saying that while it had chartered the turboprop from Helitt, the seizure of the aircraft has nothing to do with Darwin. The aircraft had been due to fly a service for the carrier to Pantelleria.
Italian media reports say the Rimini court acted on behalf of an unnamed Scottish maintenance and repair company. The unpaid maintenance bill is believed to be €100,000 ($136,700).
Flightglobal’s Ascend Online database shows the Spanish regional carrier operates three ATR 72-200s.
