This 440 was originally N9303 with Eastern Airlines.

The aircraft was sold to Conair Aviation in September 2009 and ferried, still wearing VH-PAL, to their Abbottsford, BC., base. It was deleted from the Australian register on 14th September 2009 and placed on the Canadian register as C-GYXS on 21st September 2009. It appears that Conair acquired the aircraft for parts to support the operation of their Convair fire-bomber fleet as it never flew, or even wore, its Canadian marks, lingering on at Abbottsford gradually donating parts. The last online photo of a recognisable airframe is dated 2017, and it is thought it was scrapped shortly after.
