S7 Airlines 737-800 Overruns Runway at Mirny Airport in Siberia
S7 Airlines flight S7-5241 overran the runway while landing at Mirny Airport in Siberia on June 29, coming to rest on muddy ground beyond the runway end. The Boeing 737-800, operating a Novosibirsk-to-Mirny service with 173 passengers and six crew aboard, sustained no injuries. Russia’s aviation regulator Rosaviatsiya classified the event a serious aviation incident and suspended the flight crew pending investigation. A preliminary inquiry suggests a possible technical malfunction may have contributed to the overrun. The event follows S7’s June 1 restriction barring first officers from performing landings at most airports through October 1, imposed after a surge in hard-landing incidents fleet-wide.

Boeing IT Outage Disrupts Q2 Commercial and Defense Production
A coast-to-coast IT outage struck Boeing on June 30, the final day of the second quarter, disrupting commercial and defense production at factories from Washington state to Florida. The system failure interfered with final aircraft inspections and delivery paperwork, adding pressure to near-term output targets. Boeing stated there was no reason to believe the disruption resulted from a cyberattack. At the time of the outage, Boeing was targeting 53 Boeing 737 MAX deliveries per month while operating under a Federal Aviation Administration production cap that had been raised to 47 aircraft per month.

Kenya Airways MRO Completes First Boeing 787 Dreamliner D-Check
Kenya Airways Engineering announced completion of its first Boeing 787 Dreamliner D-check, marking a significant milestone for heavy maintenance capability on the African continent. D-checks represent the deepest scheduled inspection type in commercial aviation. The announcement was made at the African Airlines Association MRO Conference in Addis Ababa, Ethiopia. South African Airways Technical also reported at the conference that its heavy maintenance fleet has grown from six aircraft at program restart to 19 aircraft currently, reflecting the broader expansion of widebody heavy maintenance capacity among African carriers and MRO operators in the region.

FAA Issues Emergency 5G Airworthiness Directives Affecting ~1,000 Aircraft in Canada
The FAA published emergency airworthiness directives effective July 1, 2026, restricting approximately 1,000 U.S.-registered transport and commuter aircraft from certain operations in Canadian airspace. Canada eliminated airport exclusion zones and signal-strength protections for radio altimeters from Lower C-Band 5G interference on July 1, leaving altimeters not certified as tolerant exposed to unreliable readings. The directives prohibit affected aircraft from conducting ILS Category II/III approaches, autoland, and EFVS landing operations in Canada. Separate type-specific directives address additional hazards on Boeing 737, 747, 757, 767, 777, and 787 variants. Terminating action: upgrade to 5G-tolerant radio altimeter systems.

Boeing 737 MAX Faces 5G-Induced Deceleration Failure and Runway Excursion Risk in Canada
A separate FAA airworthiness directive targets all Boeing 737-8, 737-9, and 737-8200 variants with a distinct 5G hazard beyond radio altimeter unreliability: 5G interference in Canada can cause thrust reversers, spoilers, speedbrakes, and idle thrust settings to fail to activate properly during landing or rejected takeoff. The resulting degraded deceleration capability creates a runway excursion risk independent of approach type or weather conditions. Effective July 1, 2026, the directive applies to approximately 832 U.S.-registered 737 MAX aircraft. Boeing reported in May 2026 that certain 737 MAX configurations would not demonstrate tolerance to Canada’s updated 5G radio environment.

Embraer Praetor 500E Receives Simultaneous FAA, EASA, and Brazilian Certification
Embraer’s Praetor 500E midsize business jet received simultaneous type certification from Brazil’s National Civil Aviation Agency, the U.S. Federal Aviation Administration, and the European Union Aviation Safety Agency on June 30, 2026. Embraer described the certification as achieved ahead of schedule. The Praetor 500E features a new cabin design and a payload increase over its predecessor. Customer deliveries are scheduled to begin in 2029. The triple certification follows the larger Praetor 600E, which received equivalent three-agency approval in April 2026. Embraer called the achievement a testament to engineering excellence and disciplined program execution.
