The Russian airline whose plane crashed in the Sinai region on Saturday says the aircraft was in good shape and the pilot was experienced.
In a statement on its website, Moscow-based Metrojet says the A321 received required factory maintenance in 2014.
Seeing as the aircraft, as an asset, was owned by significant major lessor in the market, i have no reason to doubt that.
A prerequisite of lessors is that the aircraft residual value is protected by maintenance demands as set forth in the lessor terms.
