What happened?

The incident occurred on November 10th, during the descent of flight SU1259. This is a domestic service between the Russian cities of Ufa and Moscow, scheduled to take just under two and a half hours. On this date, The Aviation Herald reports that during the descent into the Russian capital’s Sheremetyevo airport, its crew reported an electrical failure. This resulted in a partial loss of the aircraft’s electrical power supply.

The failure occurred at 34,000 feet (FL340), affecting numerous electrical systems on the aircraft. One consequence was a change in the aircraft’s cabin altitude. As such, the crew requested to descend to 10,000 feet (FL100), with air traffic control clearing them to do so shortly afterward. At this point, the aircraft entered a holding pattern. This allowed the crew to work through various technical checklists in an attempt to fix the issues.

Having done so, the flight was eventually able to land safely on runway 24R at Sheremetyevo. The touchdown occurred around 50 minutes after the crew first declared the emergency. Despite the multiple failures and the subsequent need to run through numerous safety checklists, FlightRadar24.com reports that the flight landed 21 minutes early, at 21:04 local time.

The aircraft involved

The aircraft that operated Aeroflot flight SU1259 on November 10th bore the registration RA-89104. It is one of 54 examples of the Sukhoi Superjet 100-95 in the Russian flag carrier’s fleet, of which Planespotters.net reports that 14 are currently grounded. Aeroflot took delivery of the aircraft on December 30th, 2017.

Like all of the carrier’s SSJs, RA-89104 features a two-class seating configuration. SeatGuru reports that this consists of 12 reclining business seats in a 2-2 layout, and 75 economy seats in a 2-3 layout. According to FlightRadar24.com, the aircraft has remained on the ground in Moscow since the incident on November 10th.
