Analysis

A us coast guard Dassault breguet HU-25A was climbing from low alt as a Cessna 337D was cruising in the same area at 4000 ft MSL. Subsequently, the 2 acft converged. The Cessna plt said he was adjusting his nav radio to intercept an airway, when a psgr warned him of the situation. As he looked outside, he saw the Dassault converging at a hi rate of speed. The Dassault plt said they were rolling out of a left turn, when they saw the Cessna converging. The plts of both acft initiated evasive action, but the vertical stabilizer of the Dassault hit the baggage pod on the Cessna. Both planes continued flying & landed safely.
