BenFolk,
Thank you for your comment. Accidentally I overlooked the 104 GvIAP, which lost an Airacobra indeed, piloted by Gv.Ml.Lt. Ivan Pavlovich Buzdin. Buzdin flew P-39 white '37' and was lost during the afternoon mission between 17:10-18:05. Eight 5 VA, 9 GvIAD, 104 GvIAP Airacobras were covering own troops in the Zahora area at 2300 m, as follows:

P-39 #38 - Gv.Capt. Mikhail Sergeevich Komelkov
P-39 #40 - Gv.Ml.Lt. Ivan Ivanovich Richazkov
P-39 #37 - Gv.Ml.Lt. Ivan Pavlovich Buzdin (MIA)
P-39 #42 - Gv.Lt. Yurii Borisovich Maltsev
P-39 #35 - Gv.Ml.Lt. Nikolai Nikolaevich Klimov
P-39 #36 - Gv.Lt. Yakov Yakovlevich Shevchenko
P-39 #43 - Gv.Ml.Lt. Vladimir Timofeevich Chichev
P-39 #20 - Gv.Ml.Lt. Vladimir Grigorevich Stepanov

Combat with Bf 109s. The other reported 5 VA Airacobra loss this day -as previously discussed- was Gv.Ml.Lt. Vladimir Vasilevich Dushanin from 5 VA, 9 GvIAD, 16 GvIAP. He force landed at Probota-E, 500 m and returned to his unit. These were the 2 reported Airacobra losses of the 5th Air Army on June 4, 1944. If Hartmann downed both, then his 'P-39' balance this day was 2 victories vs. 4 overclaims. (~30%)

Do you know which mechanical report removed Dushanin's plane from combat duty?
Thanks,
Gabor
