Interstate Aviation Committee

The Interstate Aviation Committee (IAC; Межгосударственный авиационный комитет, МАК) is an executive body of the Civil Aviation and Airspace Use Council of the Commonwealth of Independent States (CIS) and was formed in 1991 according to the Civil Aviation and Airspace Use Multilateral Agreement, signed on 25 December 1991.

History
In the Soviet Union, the State Supervisory Commission for Flight Safety (Gosavianadzor), under the Council of Ministers, was the predecessor of the IAC. The Gosavianadzor conducted aircraft accident and incident investigations. until the IAC was established in Minsk on 25 December 1991.

The IAC has been accredited by ICAO as an intergovernmental organisation which may be invited to attend suitable ICAO meetings (officially, ICAO does not classify these as observers).

The Aviation Accident Investigation Commission of the IAC cooperates with the Federal Air Transport Agency in investigations of aviation accidents. One publicly known and controversial IAC investigation was the 2010 plane crash that killed Polish president Lech Kaczyński.

Governance
The committee is head-quartered in Yakimanka District, Central Administrative Okrug, Moscow, Russia. Since 1991, Tatiana Anodina has been the chairperson of the committee.
