... i believe that is part of fabianfreds destruction mod ... it changes attributes for stationary planes in "technics.ini" .... so see if any mod has changed your technics.ini ( or another one is present)
C:\Program Files\Ubisoft\IL-2 Sturmovik 1946\MODS\DAMAGEMOD2\Effects\Smokes\SmokeBlack_plane.eff is the file imho and fly_zo is correct it comes with fabianfreds mod
that mod also adds smoke and fire to destroyed cars and guns and god knows what else, and is pretty cool, one of the best mods
here at my download site is a copy of all my .ini's ...in the mods folder....but the static.ini doesn't include the new soldiers and hangers by Lal_Rone
if you only need the Technics ini then put it in the STD folder in MODS...alongside the static ini you are using
The chiefs ini has extra vehicle and tank columns ....
