He left 7 IAP again in October to be posted to 153 IAP, which was equipped with MiG-3s and Airacobras.

On 2 July 1942, the Airacobras from 153 IAP claimed two Bf 109s when Adam Amkoladze claimed one north of Sukovkino Station and Karpukhin claimed a second north over Sukovkino.
On the same day, Karpukhin claimed a shared Do 217 together with another pilot south-west of Krasnaya Dolina.

On 3 July 1942, the Airacobras of 153 IAP were in combat west of Turovo and Karpukhin and Aleksey Nikitin claimed a Bf 109 each.

Starshiy leitenant Mikhail Ivanov and Karpukhin claimed a shared Bf 109 south of Otrozhka on 28 July.

After claiming a Bf 110 on 12 August 1942, he disappeared without a trace after an air combat to become MIA.

At the time of his disappearance, Karpukhin was credited with 1 biplane victory and a total of 7. These had been claimed in 229 combat missions.
