A Boeing-737 passenger jet belonging to NordStar airlines made an emergency landing at Krasnoyarsk Airport because of an improperly closed door that resulted in cabin decompression, local law enforcement authorities said Friday.
"A commission that checked the aircraft's technical condition established that it was in working order, but before the take-off its left front door had not been closed properly, which triggered the decompression alarm," a regional transport prosecutor told Interfax, adding it was the first such incident in the region.
The pilot of the aircraft en route to Norilsk decided to return to Krasnoyarsk after the cabin decompression alarm went off. The plane landed successfully at 6:26 a.m. Moscow time, having used up its emergency fuel reserves prior to landing.
None of the 111 passengers and crew on board the plane were injured.
Local prosecutors have opened an inquiry into the airline's safety checks.
