N674TH

N674TH is a Kaman K-1200 operated by TIMBERLINE HELICOPTERS INC. SkyMeter has tracked 302 flights totalling 677 hours of airtime via ADS-B across 3 callsigns. The most frequent segment is US-2407 to 0CA3. Service window in our records spans 440 days. Of those flights, 2 (0.7%) carry at least one detected incident: a go-around, unstable approach, stall warning, or runway excursion. The Kaman K-1200 has a maximum takeoff weight of 12,000 lb, medium wake category.

About the Kaman K-1200

The Kaman K-MAX is one of aviation's most distinctive helicopters, instantly recognizable by its intermeshing twin-rotor configuration that eliminates the need for a tail rotor entirely. Developed by Kaman Aerospace and certificated in 1994, the K-1200 was purpose-built for external load operations: aerial logging, firefighting, construction, and utility work where precision lifting matters more than passenger comfort. Its synchropter design allows both rotors to contribute fully to lift rather than wasting power on anti-torque, giving the K-MAX an external lift capacity of 6,000 pounds at sea level despite a relatively modest single Honeywell T53-17 turboshaft engine producing just 1,800 shaft horsepower.

The cockpit is stripped-down and utilitarian, with the pilot seated high and forward for maximum visibility of the cargo hook directly below. Kaman built only around 38 manned K-MAX helicopters before pausing production in 2003, then resumed manufacturing in 2015 after the type proved its worth in Afghanistan as an unmanned cargo resupply platform for the U.S. Marine Corps.

The K-MAX remains the only intermeshing-rotor helicopter in commercial production, a living link to Kaman's pioneering work on synchropter designs dating back to the 1940s. Its narrow fuselage, high power-to-weight ratio, and exceptional hover performance make it the tool of choice for operators working steep mountain terrain, dense forests, and high-altitude construction sites where conventional helicopters struggle. SkyMeter has tracked flights across airframes and operators, with the largest observed operator.
