In the VVS statistical digest, does the denominator in the aircraft tables indicates non serviceable planes in squadrons, or planes in overhaul/repair? As an exemple :

It says there is a total of 137 Il-2 planes, including 43 "faulty" Il-2s. Are these 43 Il-2s merely non serviceable or in repair depots?
