PS-712 from Istanbul (Turkey) to Kiev (Ukraine), was enroute at FL340 about 210nm south of Odessa (Ukraine) when the crew needed to shut the right hand engine (CFM56) down due to a low oil pressure indication. The aircraft landed safely on Odessa's runway 34 about 35 minutes later.
A replacement Embraer ERJ-190 registration UR-EMD reached Kiev with a delay of about 6 hours.
The airline reported the aircraft made an emergency landing at Odessa due to technical reasons.
On Jun 18th 2021 Ukraine's NBAAI reported the oil pressure dropped to 30psi due to the blockage of the engine driven oil pump by remains of the polytetrafluoroethylene seal of the #3 bearing. The engine manufacturer identied the desctruction of the seal as a design flaw.
