Investigation team of the Interstate Aviation Committee has completed the investigation of the accident with An-2 RA-84566 aircraft owned by Aviapartner, Ltd occurred in the Ulyanovsk region on 17.09.2016.

Most probably, the accident with An-2 RA-84566 aircraft was caused by the destruction of the nose gear mount attachment bolted-type connection resulted from one-time off-design load as a result of obstacle in-flight collision occurred during  the areal works performance, that resulted in the separation of the mount attachment from the fuselage in course of landing. Thereby the gear design integrity was broken that resulted in the fuselage damage.

Most probably, the contributing factors were: 

  • violation of An-2 AFM, Chapter 2, Minimum cabin crew, which specifies a two-member crew when performing the areal works:
  • violation of FAR-128, item 7.4 according to which the flights during the chemical treatment of flat areas (fields, gardens, vinelands, etc.) should be performed at a hight not lower than 5 m.

In violation of the Air Code of the Russian Federation, article 96, the aircraft owner provided to the Investigation team neither the PIC information, nor the aircraft documentation.

Appropriate safety recommendations based on the investigation results were developed. .
