JA01AM is an ATR 42-600, a twin-engine turboprop. SkyMeter has tracked 3,472 flights totalling 5,239 hours of airtime via ADS-B across 14 callsigns. The most frequent segment is RJFT to RJOO. Service window in our records spans 441 days. Of those flights, 30 (0.9%) carry at least one detected incident: a go-around, unstable approach, stall warning, or runway excursion. The ATR 42-600 has a 81 ft wingspan, a maximum takeoff weight of 41,005 lb.

About the ATR 42-600

The ATR 42-600 represents the latest evolution of Europe's most successful regional turboprop family, combining French aerodynamic design with Italian manufacturing in a partnership between Airbus and Leonardo. Launched in 2007 and entering service in 2012, the -600 variant brought new Pratt & Whitney PW127XT engines, a glass cockpit, and improved cabin comfort to the proven ATR 42 airframe that first flew in 1984. With seating for 48 passengers in typical configuration, the type carved out a niche serving thin routes and island communities where jet economics don't work. Its fuel burn is roughly half that of comparable regional jets on sectors under 300 nautical miles.

The aircraft's high-wing configuration and rugged landing gear make it particularly suited to unpaved or short runways, while its maximum cruise speed of 270 knots and range of 800 nautical miles cover the vast majority of regional route networks. Operating from sea level to airports at 8,000 feet, the ATR 42-600 thrives in hot-and-high conditions that challenge piston twins, yet costs significantly less to operate than turbofan alternatives. The type has found favor with carriers serving Japan's island chains, Scandinavian fjord communities, and Caribbean inter-island routes where frequency matters more than speed.

ATR's focus on operational simplicity shows in the -600's systems: hydraulically actuated flight controls, proven PT6-family engines, and straightforward maintenance requirements that allow operation from remote bases without extensive ground support. The aircraft's relatively low approach speed of around 100 knots and docile handling characteristics make it accessible to pilots transitioning from smaller turboprops, while its STOL performance opens airports that jets cannot serve. SkyMeter has tracked flights across airframes and operators, with the largest observed operator.
