Yakutia Superjet overrun: incorrect runway condition reported to crew
The Russian Federal Air Transport Agency (Rosaviatsiya) reported that the runway friction coefficient at Yakutsk Airport, Russia, was less than reported in the recent Sukhoi Superjet overrun accident.
On October 10, Yakutia Airlines flight 414, a Sukhoi Superjet, suffered a collapse of the main landing gear and a fuel leak when overrunning the runway into a construction area after a landing at Yakutsk.
Rosaviatsiya states that a runway friction coefficient of 0.45 was communicated to the flight during the approach After the accident new measurements were performed, showing friction coefficients of 0.25, 0.32, and 0.25 and the presence of ice on the runway.
The aircraft was dispatched with a deactivated thrust reverser on engine no.2. According to the limitations of the minimum equipment list (MEL), landing with deactivated engine reversers is allowed at a friction coefficient of not less than 0.4.
ICAO Doc 9137 (Airport Services Manual) – Part 2 (Pavement Surface Conditions), states that the braking action with a friction coefficient > 0.4 can be described as ‘good’. While the braking action for 0.25 as ‘poor’ and 0.32 as ‘medium’.
