Recently, the airline purchased a 737-200C, N808TA, which they are still awaiting delivery on. No details are available for the whereabouts of this airframe. It's been reported that TransAir will use the 737 to compete against Aloha Air Cargo, as their working agreement has ended.
The history of this Convair is rather vague. According to FAA records, this CV-640 was built in 1957. A database reports that it held the registration N4405, but the FAA records does not show it belonging to this CV-640. In the mid-60s, this CV-640 spent time in the Hawaiian Airlines fleet (f/n 39) as N4405. In the 1970s, it was with Pacific Western Airlines [PW/PWA], registered as CF-PWO. In the early to mid 1980s, it went to Echo Bay Mines and North Cariboo. Viking International acquired the CV-640 as N587CA in the mid 80s, after it was converted into a freighter. In the 1990s, it went to Kitty Hawk Air Cargo. In March 1999, it was sold to Rhoades Aviation of San Juan, Puerto Rico.
