Seversky SEV-3M-WW in Colombian Service
First flying in 1933, the Seversky SEV-3 was a three-seat monoplane amphibian. It could either be fitted with twin amphibious floats which had main wheels fitted in the floats to allow it to operate from land, or with a fixed tailwheel undercarriage with the mainwheels enclosed in large fairings.
The landplane version was developed into a trainer for the United States Army Air Corps and designated BT-8. A total of 30 were ordered, but they proved to be underpowered and were replaced by the North American BT-9.
The Colombian Air Force ordered six SEV-3M-WW amphibians. Only four were actually delivered.
