A photograph of the Columbia XJL-1, supplied by Neil C Aird of Kingston, Ontario, showing its appearance in September 1968, at the Ryan Airfield, Tucson, Arizona. This is the second of the two prototypes, while the first is now undergoing restoration in Baltimore, Maryland.

The Columbia XJL-1 was built to Grumman designs as a potential successor to the J2F-6 "Duck" as a general utility amphibian.
