Piper Aircraft Pa-28-161

Single Piston

The Piper PA-28-161 Warrior is a four-seat, single-engine trainer and personal aircraft that became one of general aviation's most successful designs after its introduction in 1974. Built as the entry-level member of Piper's Cherokee family, the Warrior paired a 160-horsepower Lycoming O-320 engine with a tapered wing design borrowed from the Arrow, delivering docile handling characteristics that made it a favorite of flight schools worldwide. The type's forgiving stall behavior, stable cruise performance, and straightforward systems earned it a reputation as an ideal platform for ab-initio training and time-building. With a maximum takeoff weight of 2,440 pounds and a cruise speed around 115 knots, the Warrior occupies the sweet spot between economy and capability for private pilots and training operations. Its low-wing configuration provides excellent visibility during pattern work, while the fixed tricycle gear and simple fuel system minimize operational complexity. The Warrior II (1977-1994) and Warrior III (1995-present) variants introduced incremental refinements including improved avionics, interior appointments, and a slightly more powerful engine option, but the core airframe remained largely unchanged, a testament to the original design's effectiveness. Production continued for nearly five decades, with thousands of airframes delivered to flight schools, flying clubs, and private owners across six continents. The type remains in active production today, now marketed as part of Piper's trainer lineup alongside the Archer and Arrow. SkyMeter has tracked 59 flights across 19 airframes and 14 operators, with APOGEE AIR VENTURE LLC the largest observed operator.

Safety in context

The incident rate counts flights with ANY safety event detected by SkyMeter: go-arounds (a routine response, not a failure), unstable-approach gate flags (advisory thresholds), rejected takeoffs (the system working as designed), and runway events. It is NOT an accident rate or fatality rate. For accident statistics, refer to the NTSB Aviation Accident Database (USA) or the Aviation Safety Network. See methodology for what each event type measures.
