Voronezh OOO "Experimental Design Bureau of Engine Building" (OKBM), involved in creating systems for Russian civil aircraft MS-21 and SJ-100, faces bankruptcy. A lawsuit was filed in the arbitration court by one of the enterprise's contractors, Promservis-2007.

In spring, the company's debt reached 771 million rubles. The authorities of the Voronezh region appealed to federal structures with a request to help the enterprise stabilize the situation.

Currently, the provision of a preferential credit line for 1 billion rubles, as well as the restructuring of obligations, is being discussed.

OKBM develops aircraft kits for the wing mechanization displacement system for the MS-21-310, or more simply – flaps.
