The European Aviation Safety Agency (EASA) validated Ikhana’s RWMI DHC-6-200HG Twin Otter modification. As such, the Murrieta, Calif.-based company now holds STC approvals from the FAA, Transport Canada and EASA for the modification.

This STC increases the payload capabilities of the basic DHC-6-100/-200 from 11,579 pounds to 12,500 pounds, providing an increase of 921 pounds, or nearly 8 percent. Operations are allowed to the full 620 shp (50 psi torque) of its PT6A-27 engines, effectively transforming a DHC-6-200 to match the capabilities of a DHC-6-300.  

“Validation of our RWMI DHC-6-200HG STC provides added capabilities for operators of DHC-6-100 and -200 Twin Otters who follow European EASA regulations,” said John Zublin, president and CEO of Ikhana. “The legacy -100 and -200 series aircraft tend to have lower empty weights, by approximately 300 to 500 pounds, when compared to a similarly equipped DHC-6-300. This makes our DHC-6-200HG an attractive alternative for adding payload capacity and revenue.”
