company also received concession to fly from Stord via Skien Airport, Geiteryggen to Oslo. By March 1987, traffic had increased so much that the company instead put a larger, 20-seater Twin Otter aircraft into service. Additional concessions to fly to Haugesund were also granted the same year, as were direct services to Oslo, making the stops in Skien unnecessary. In 1985, the company joined the joint venture Commuter Service, along with the other regional airlines Mørefly, based in Ålesund, Trønderfly, based in Trondheim, and Norsk Flytjeneste, based in Sandefjord. The goal was to coordinate the services, and grow through newer, smaller routes. On 20 June 1986, Coast Aero Center was awarded the concession for flying from Stavanger to Geilo Airport, Dagali until 1991. The airline put into service a Beechcraft Super King 200. The ridership from Geilo turned out to be too low, and both Coast Aero Center and Norving terminated their routes. In 1986, the revenue was NOK 14 million and the company had 24 employees. That year, they chose to connect to the PNR/Smart booking system. In 1988, the company also bid for operating parts of the Norwegian Air Ambulance. The company was thrown into financial distress on 7 February 1988, when Den norske Creditbank (DnC) announced that they would not issue more credit. At the time the company had nine daily routes and 35 employees. All services were immediately suspended. It had a debt of NOK 23 million, of which DnC demanded NOK 13 million paid by 10 February; the bank later gave the company three weeks to find the capital. On 17 February, a proposal for refinancing was made, where the hangars were sold to the local municipalities, who would also make a guarantee for NOK 2 million. DnC would delete part of the debt, and additional capital would be granted from Kosmos-owned Norsk Air. This was not sufficient, and on 29 April Coast Aero Center filed for bankruptcy. Asbjørn Utne had to file for personal bankruptcy. Reestablishment Following the bankruptcy, the estate was purchased by Coast Air. In 1989, the new company received a one-year concession to operate from Haugesund to Bergen and Stavanger, and from Geilo to Oslo and Stavanger. The company used de Havilland Canada Twin Otter aircraft. The following year, Coast Air also received the concession for operating the subsidized routes to the newly opened Fagernes Airport, Leirin.
