Aeroflot Flight 315 (1960)

On 26 February 1960, the An-10A operating this flight crashed short of the airport runway while on final approach.

The descent was normal and the pilot reported reaching the marker beacon at an altitude of 200 meters, the flight was then cleared to land.

When the aircraft penetrated the cloud base the crew switched to visual flight rules (VFR).

[1] Construction of the An-10 involved, serial number 9401801-18-01, was completed at the Voronezh aircraft factory on 24 January 1960 and it was transferred to the civil air fleet.

Testing eventually revealed that icing of the horizontal stabilizer created a supercritical angle of attack, that caused a sudden pitch down of the aircraft when the flaps are lowered to the maximum setting of 45 degrees.
