Engineering modification house Ikhana Aircraft Services (Booth No. C7116) expected to receive FAA supplemental type certification (STC) of its DH-6 Twin Otter fuselage life extension by the time the NBAA show began, adding to a range of other upgrades the company offers for the twin-engine turboprop.

DHC-6 airframes are fatigue-life limited at 66,000 hours or 132,000 flights, whichever occurs first, according to Ikhana. The wing-box life limit is 33,000 hours or 66,000 flight cycles, about the half-life of the aircraft. Ikhana’s RWMI DHC-6 re-life fuselage, developed by its formerly named RW Martin, Inc. subsidiary, extends the life of the rugged commuter plane. The fuselage modification, combined with other Ikhana STCs for the Twin Otter including the RWMI DHC-6 re-life wing box and DHC-6-200HG increased gross weight product “essentially transforms a DHC-6-200 into a DHC-6-300,” the company says.
