Executive Summary:On Friday 15.12.2000 at 16.46 (Finnish time is used in this report) there was an air traffic incident over Espoo, where the required separation minima between two aircraft were violated. An MD-83 airliner operated by Finnair Oyj, registered OH-LMG, call sign FIN2162, was approaching Helsinki-Vantaa airport and was about to reach its cleared flight level (FL) 80, when it received a resolution advisory ?Climb? from its TCAS (Traffic Alert and Collision Avoidance System). The device showed that the other aircraft, an airliner of type IL62M, registered RA 86532, call sign AFL204, was at level flight 500 ft (about 150 m) below FIN2162, on its front left side at a distance of approximately half a nautical mile. AFL204 had been cleared to FL70. It appeared on ATC secondary radar (SSR/MSSR) screens for the first time at the same time when FIN2162 received the TCAS resolution advisory. The ATC radar data showed that AFL204 was then at FL76.

There were altogether 230 passengers and 17 crew members in the aircraft. No one was injured and no damage was caused.
