Operator unknown. Originally delivered to the Belgian Air Force Sep 54 as RM-9/OT-ZAI. To Air America Apr 78 as N51964. Believed to have gone on the Honduras register in 1978 too. Was in Tamiami (TMB) for a number of years and re-registered N702JM in Dec87. Re-reg N510RP in Jul 88. At some point it made its way to Minneapolis - Anoka County-Blaine / Janes Field (ANE) MN. It was apparently registered N702JM again in 2005, but the last photo I've seen of it, semi derelict at ANE in 2011, shows it still with reg N510RP.
