This factory built twin engined Twin Ranger was constructed by Bell Helicopters in 1995 and was operated in the US before it was exported to Panama in March 2001. It was one of very few Bell 206LT Twin Rangers ever constructed. The aircraft was imported to Sweden by Arlanda Helicopter in February of 2005. The aircraft was imported at the same time as the Bell 206L-3ST Gemini ST SE-JJA.

SE-JJB was eventually converted to a single engine Bell 206 L4 Long Ranger IV - the first L-4 in Sweden.

The helicopter was sold to a private company in Stockholm in 2007. It was privately operated by MJ Constructor together with the UH-1H SE-HUJ for many years until the Long Ranger was replaced by a Bell 407 (SE-JFJ) in February 2015. SE-JJB was sold to another private company in the Stockholm region.
