The Romanian Air Force 90th Airlift Base (Baza 90 Transport Aerian) is located at the Henri Coandă International Airport, near Bucharest. In 1949, the 49th Transport Group was the first unit to be settled at Otopeni airfield. Later, in 1971, a special squadron was commissioned here and after few years this squadron became the 50th Airlift Wing. On March 1, 1990, by gathering together these two units, the 90th Airlift Base was officially formed.
Three crewmen were killed on November 7, 2007, including Commander Bucur Nicolae (one of the most experienced RoAF pilots, with over 2,700 flying hours), when an IAR-330 Puma SOCAT helicopter belonging to the 90th Airlift Base crashed in Ungheni, near Piteşti, Argeş County. The aircraft was performing a night training mission at the moment it disappeared from radar. Immediately after the crash, the 90th air base detached two helicopters for a search and rescue mission.
