A Boeing 737-800 operated by Russia’s S7 Airlines overran the runway after landing at Mirny Airport (MJZ) in Russia’s Sakha (Yakutia) Republic on June 30. The aircraft, operating a scheduled domestic flight S7-5241 from Tolmachevo Novosibirsk International Airport (OVB), came to rest beyond the end of the runway with 173 passengers and six crew members onboard. Nobody was injured, but Russian authorities immediately launched investigations into the serious incident.
The runway excursion comes just days after reports emerged that S7 Airlines had temporarily prohibited most first officers from performing landings across much of its network following a rise in hard landings. While there is currently no evidence linking the two events, their close timing has drawn renewed attention to the operational challenges facing Russian airlines.
Authorities Investigate Runway Excursion At Mirny
According to Russia’s transport prosecutor, reported by RBC News, the Boeing 737-800 departed Novosibirsk as scheduled before overrunning the runway after landing at Mirny Airport. Emergency services responded immediately, while investigators from both the transport prosecutor’s office and Russia’s transport investigation authorities began examining the circumstances surrounding the occurrence.
All 179 people onboard safely evacuated the aircraft, and no injuries were reported among passengers or crew. Preliminary information released by investigators suggested the runway excursion may have been linked to a technical malfunction, although authorities stressed that the investigation remains in its early stages and no definitive cause has been established.
S7 Airlines told Rossiyskaya Gazeta the following regarding the incident, as translated by Simple Flying:
“After the aircraft came to a complete stop, the captain acted in accordance with established procedures.”
Airline Launches Internal Investigation
S7 Airlines confirmed that it has opened its own investigation alongside the official government inquiries. The airline stated that passengers were disembarked using mobile stairs after the aircraft stopped beyond the runway. The flight crew has been temporarily removed from flying duties in accordance with the carrier’s standard internal procedures, pending completion of the investigation. Mirny Airport was temporarily closed until the runway was cleared.
Russia’s Federal Air Transport Agency, Rosaviatsiya, subsequently classified the occurrence as a “serious aviation incident”, as reported on their official Telegram Channel. The airport temporarily suspended arrivals and departures while authorities assessed the condition of both the runway and the aircraft, affecting operations at the remote Siberian airport.
Mirny serves one of Russia’s most important diamond mining regions, making reliable air service particularly important due to the area’s remote location and limited alternative ground transportation options. Although runway excursions are relatively uncommon in commercial aviation, each event typically triggers comprehensive technical, operational, and human factors investigations before a final report is issued.

Russian Airline Bans First Officers From Landings After Surge In Hard Landing Incidents
Russian carrier S7 Airlines has barred most first officers from performing landings after a series of hard landings, highlighting operational pressure
First Officer Landing Ban Remains Under Scrutiny
The runway excursion occurred just two weeks after reports suggested that S7 Airlines had imposed temporary restrictions on first officers performing landings at most destinations between June 1 and October 1. According to Russian industry reports, the measure followed an increase in hard landings that exceeded structural inspection limits, resulting in additional maintenance requirements and aircraft downtime.
The restriction reportedly allows first officers to continue landing at the airline’s major bases, including
Moscow Domodedovo Airport (DME), Novosibirsk, Irkutsk, and Vladivostok, while exemptions exist for training flights and proficiency checks. S7 has not publicly issued a detailed explanation, although Simple Flying has reached out to the airline for a comment. But aviation analysts have suggested the policy reflects the airline’s effort to preserve aircraft availability as sanctions continue to complicate maintenance and spare-parts supply chains.
It is important to clarify that there is currently no indication that the Mirny runway excursion was linked to the first officer’s landing restrictions. The official investigation is expected to determine whether technical issues, operational factors, environmental conditions, or a combination of causes contributed to the Boeing 737-800’s runway overrun. Until investigators release their findings, any connection between the two events would remain purely speculative.
