Mahan Air flight W51152, an Airbus A310-304, experienced a sudden manoeuvre in Syrian airspace due to a potential avoidance maneuver involving two USAF McDonnell Douglas F-15 Eagle fighter jets. The flight departed Tehran, Iran, at 14:43 UTC, bound for Beirut, Lebanon, and continued en route, landing at Beirut Airport at 16:50 UTC. Syrian Civil Aviation Authority (CAA) reported the crew responded to a TCAS-RA warning between MODIK and TAN waypoints by applying a high rate of climb. The US Military’s Central Command overseeing American troops in the region stated the F-15 aircraft was conducting a visual inspection of the Iranian aircraft when it passed near the Al-Tanf U.S. military base. The F-15 maintained a safe distance of approximately 1,000 meters from the Al-Tanf U.S. military base, located near the TAN waypoint (33ø 28′ 57N 38ø 39′ 15E). The flight followed airway G202 at FL340 for a procedure turn over TAN towards airway A21.Mahan Air flight W51152, an Airbus A310-304, experienced a sudden manoeuvre in Syrian airspace due to a potential avoidance maneuver involving two USAF McDonnell Douglas F-15 Eagle fighter jets.
