Built as 44-76906 for the USAAF, to the RAF as KN497 and to the West German Air Force in 1956. Sold to a US owner as N10801 in 1968 with the apparent intention of using it in Biafra but the aircraft remained stored in Portugal, eventually making it to the US in 1978. Delivered to the FA Salvadorena in 1985 and became the fourth airframe converted to a BT-67 by Basler in 1990. Withdrawn and stored at Ilopango by February 2011, still present in 2019.
