While the FAF was successful in its mission, the conditions were not easy. Spare parts for the FAF planes were scarce — parts from the US (Buffalo and Hawk), Britain (Hurricanes), and Italy (G.50) were unavailable for much of the war. Repairs took often a long time, and the State Aircraft Factory was burdened with restoration/repair of captured Soviet planes, foreign aircraft with many hours of flight time, and the development of indigenous Finnish fighter types. Also, one damaged bomber took up workshop space equalling three fighters.
