MOSCOW, January 15 (RAPSI) - Transaero air carrier has filed a petition to declare Ilyushin Finance Co aviation lessor bankrupt, according to the records of the Voronezh Regional Commercial Court.

Currently, several Transaero applications over the lessor’s alleged unjust enrichment are pending in the Moscow Commercial Court. The air carrier is seeking to recover over 2 billion rubles from Ilyushin Finance Co in total.

In September, the Moscow Commercial Court returned a 1.1 billion-ruble ($18 million) unjust enrichment claim against Ilyushin Finance to Transaero. The court noted that the plaintiff in its application also petitioned for deferral of repayment of the state duty totaling to 200,000 rubles. However, the court dismissed this motion.

Transaero found itself unable to pay its debts valued at 250 billion rubles (about $4 billion) in 2015. The government-approved plan of transferring 75% of company’s shares to Aeroflot failed. Its problems resulted in mass flight cancels and delays.

In October 2015, Sberbank and Alfa Bank filed bankruptcy petitions against the troubled airline. The Commercial Court of St. Petersburg and Leningrad Region initiated bankruptcy procedure against Transaero on December 16.

The Commercial Court of St. Petersburg and Leningrad Region declared Transaero air carrier bankrupt in September 2017.
