Russian aero engine builder Perm Motors has halted maintenance and spares supply to Aeroflot-Russian International Airlines (ARIA) following a dispute over the non-payment of $8 million for work on its engines which power the carrier's Ilyushin Il-96-300 and Tupolev Tu-134.

Perm has already applied to a Russian court for the money ARIA still owes for work done in 1996, although that sum is insignificant compared with the current debt.

ARIA flies five Il-96-300s powered by the Perm PS-90A and several Tupolev Tu-134s powered by the Perm D-30. If the dispute is not settled, the aircraft could soon start to be grounded. The two companies have begun negotiations to reach an agreement.
