Adam Kontsevoy was born in 1916.

When Germany invaded the Soviet Union on 22 June 1941, leitenant Kontsevoy served in 147 IAP. This regiment operated on the Northern Front and was equipped with Polikarpov I-15bis and I-153s.

The Northern Front was divided into the Karelian and Leningrad Fronts on 23 August and 147 IAP became part of the Karelian Front.

On 4 April 1942, 147 IAP became a guard’s unit and renamed to 20 GIAP.

On 23 April, kapitan Aleksei Khlobystov claimed six shared enemy aircraft (1 Bf 110, 2 Bf 109s and 3 Ju 87s) over Lake Pyayve-Yavr together with starshiy leitenant Kontsevoy, starshiy leitenant Ivan But (Hurricane), starshiy leitenant Dmitriy Gorelysev, mladshiy serzhant Mikhail Bychkov, serzhant A. I. Chibisov, serzhant Petelin and serzhant Zurov.
Starshiy leitenant But and serzhant Chibisov were both shot down and killed during the day.

Sometime during 1942-1943, Kontsevoy was transferred to 5 GIAP on the South-Western Front. This regiment was equipped with La-5s.

Major Kontsevoy was lost during a combat mission on 13 August 1944.

At the time of his death, Kontsevoy was credited with 1 shared biplane victory and a total of 4.
