The large cabin allows easy access to seating and storage, and reduced the distance between student stations and instructor positions.[8] In addition, as navigator training requirements were reduced when several USAF mission design series aircraft eliminated the navigator position, several T-43A aircraft had their navigator training systems removed and were modified to a transport aircraft configuration designated as CT-43A, such as one previously operated by the then-6th Air Mobility Wing (6 AMW) at MacDill AFB, Florida, in support of United States Southern Command (USSOUTHCOM) for transport of the USSOUTHCOM commander in Central and South America.Among the T-43s removed from navigator training and converted to CT-43A executive transports, one aircraft assigned to the 86th Airlift Wing (86 AW) at Ramstein Air Base, Germany, to support United States European Command (USEUCOM) crashed in Croatia in 1996 while carrying U.S. Secretary of Commerce, Ron Brown, and 34 other passengers.There were no survivors and subsequent investigation determined that this was a controlled flight into terrain (CFIT) mishap as a result of pilot error.As of 2022, a single heavily modified NT-43A remains flying as a testbed aircraft in the Air Force Materiel Command (AFMC).
