IKHANA RWMI DHC-6-300HG™ Twin Otter Standard Commuter Category STC Passes a Key Certification Milestone to Allow a 14,000 lbs. MTOW

Feb. 24, 2015
As a Standard Commuter Category STC, DHC-6-300 and DHC-6-400 operators will be able to operate, in revenue service without special purpose restrictions.

IKHANA Aircraft Services (IKHANA) announced that the Federal Aviation Authority (FAA) has accepted IKHANA’s G-1 Issue Paper outlining IKHANA’s approach for certifying their RWMI DHC-6-300HG™/-400HG™ Supplemental Type Certificate (STC) as a Standard Commuter Category STC.  “The FAA’s acceptance of our RWMI DHC-6-300HG™/-400HG™ STC certification methodology is a key milestone that ensures our path to final approval is clearly identified,” states Mr. John A. Zublin, President and CEO of IKHANA. “Additionally, we have satisfactorily completed our FAA approved landing gear drop testing, flight loads analysis, and, now, we are ready to effect aircraft modifications and move ahead with our flight testing phase.  The Standard Commuter Category STC addresses a typical Twin Otter operator’s need for as much payload as possible and, of course, for increasing revenue.”

The RWMI DHC-6-300HG™ STC increases the payload capabilities of the basic DHC-6-300 and, ultimately, DHC-6-400 Twin Otter Series aircraft from 12,500 lbs. (5670 Kg) to 14,000 lbs. (6350 Kg).  As a Standard Commuter Category STC, DHC-6-300 and DHC-6-400 operators will be able to operate, in revenue service without special purpose restrictions.  IKHANA’s RWMI DHC-6-300RG™/-400RG™ STC is currently limited to special missions operations, constraining operators who carry passengers for revenue service.

The FAA uses issue papers to provide a structured means for describing and tracking the resolution of significant technical, regulatory, and administrative issues associated with a project. In particular, the G-1 issue paper establishes and communicates a formal agreement for the major issues, regulations, and special conditions that will apply between IKHANA, the FAA and a foreign civil aviation authority.
