Delivered new to the Colombian Government as HK-189-X in 1955 and flown by several operators as HK-189 between 1959 and 1997 by which time the fuselage was stored at Villavicencio as HK-189-P. Registered in Canada as C-GGBF in December 2002 to Sealand Aviation and rebuilt as a testbed for the Trace Orenda powerplant. Re-registered in 2012 as N600AX to Trace Engines of Midland Texas and first flown there with the new powerplant in May 2012.

This Beaver was rebuilt at Sealand at Campbell River and fitted with the Trace V8 Orenda engine of 600HP and a four blade composite reversing prop. Following certification in the US it then went to Val D'or Quebec for float certification. Possibly due to lack of interest in this conversion the program was dropped. The aircraft was de-registered and sold to a Canadian buyer. The engine was removed and it was transported back to Campbell River in a trailer. It remains un-registered. It will some day emerge as a Turbo Beaver, or perhaps will revert to its original R985 engine, but time will tell.

This 1955 built Beaver spent it's first forty-four years in Colombia, the last few of these with the fuselage in open storage at Villavicencio. Bought by Sealand Aviaion, it was eventually registered in Canada as C-GGBF. Rebuilt for use by TRACE Engines of Midland, TX to continue development of the Orenda OE600 V-8 engine program they bought from Orenda.
