Originally World War II 42-24337, this C-47 has been with EASI - Environmental Aviation Services Inc. since December 1979, but operated out of Houma by Airbourne Support Inc. for Clean Gulf Associates since 1997. Parts from RCAF Dakota 12930 (c/n 13303), that crashed in the Canadian arctic in 1971, were used to rebuild N64767, which sometimes leads to confusion about its identity. The FAA incorrectly lists it as c/n 13303 after 1985, but the fuselage is in fact c/n 10199 ex USAAF 42-24337.
