Mexican airliner Interjet is inspecting its Russian-made Superjet 100 aircraft after cracks were found in one of the Sukhoi planes, according to reports Monday.

“The security of our passengers and aircraft is our priority. We would like to inform that the Russian Aviation Authority has issued an airworthiness directive, number AD 2016-322-02, which requires all operators to inspect their Superjet100 aircraft,” the Russian Federal Air Transport Agency said, in a statement.

Earlier this week, the agency suspended six flights of Superjet 100 aircraft operated by Russian airliners Aeroflot and IrAero after authorities found damage to the stabilizer on one of the planes.

Mexico’s consumer protection agency said at least 25 flights and over 680 passengers have been affected by the inspections. It had initially issued a directive confusing the Superjet with the Tupolev Tu-154 aircraft that crashed in the Black Sea near the Russian city of Sochi on Sunday, killing all 92 people aboard, according to the Associated Press.

Sukhoi is part of the state-owned United Aircraft Corp. and Interjet has bought several Superjet 100 aircraft. However, the 100-seat airliner has been marred by safety concerns. In 2012, a Superjet plane crashed during a promotional flight in Indonesia killing 45 people. This led the carrier Aeroflot to suspend four Superjet planes.
