Incident Overview

Date: Monday 26 December 1960
Aircraft Type: Ilyushin Il-18A
Owner/operator: Aeroflot, Ulyanovsk Advanced Flying Training College
Registration Number: CCCP-75651
Location: 1,2 km NE of Ulyanovsk Airport (ULY) – ÿ Russia
Phase of Flight: Approach
Status: Destroyed, written off
Casualties: Fatalities: 17 / Occupants: 17
Component Affected: Horizontal stabilizerHorizontal stabilizer
Category: Accident
An Ilyushin 18A aircraft crashed near Ulyanovsk Airport (ULY) in Russia, resulting in the deaths of all 17 crew members. The aircraft lost altitude rapidly, nosed down, and subsequently crashed in a plowed field, resulting in flames. This incident mirrors a similar occurrence in 1961, where the crew regained control by raising flaps and adding power. Ice accretion on the horizontal stabilizer could have contributed to the loss of control during approach to Ulyanovsk Airport (ULY).An Ilyushin 18A aircraft crashed near Ulyanovsk Airport (ULY) in Russia, resulting in the deaths of all 17 crew members.

Description

An Ilyushin 18A aircraft was destroyed in an accident near Ulyanovsk Airport (ULY), Russia. All 17 on board were killed. The airplane was approaching Ulyanovsk when it suddenly nosed down from an altitude of 120-150 m, just after the crew had selected the flaps down to 40 degrees. It crashed in a plowed field and burst into flames. A similar occurrence happened in 1961, but this time the crew managed to regain control by raising the flaps and adding power. Test flights in icing conditions showed that the Ilyushin 18 was vulnerable in icing conditions. Ice accretion on the horizontal stabilizer could result in a loss of control. Control was lost when the flaps were selected down to 40 degrees while on approach to Ulyanovsk Airport (ULY). Icing was a possible factor. The airplane was on a training flight carrying a crew and several workers of the Voronezh aircraft factory. Cause: Loss of control due to tailplane icing.
