The Oyonnax-Arbent airfield (LFLK) has officially ceased operations on August 9th, 2024 and has been removed from current charts after 90 years of existence and 58 years as a public-use facility.
With a single concrete runway (04/22) of 860 meters, the airfield primarily supported general aviation, including private flights and flying clubs. The closure results from declining traffic, rising maintenance costs, and a strategic shift in land use by local authorities.
Despite its utility for VFR operations (especially as an alternate or technical diversion) and uniqueness in the Jura mountains after the closures of St-Claude and Arbois, reduced demand and financial constraints made the airfield's operation unsustainable.
A move of the based operators to LFHS Bourg-en-Bresse with hangar construction was financed by the region. The site is now slated for expansion of the neighboring commercial / industrial zone.
