- !Moderate cruise speed (137 kt) limits business travel appeal
Piper Archer
The Piper PA-28 Archer is the four-seat touring workhorse of the PA-28 Cherokee family, offering 180 horsepower and a meaningful step up in useful load and cruise speed over the Warrior. The Archer lineage traces back to 1963 with the original PA-28-180 Cherokee 180, one of the first truly practical four-seat Cherokees, and extends through continuous production to the present day as the Archer LX and Archer DLX — making it one of the longest-running production aircraft in general aviation history.
- +Excellent cross-country performer: 125 KTAS cruise, 565 nm range, four comfortable seats
- +Bulletproof engine & parts support: O-360 is most-produced aircraft engine; PA-28 fleet largest in GA
- +Docile handling & honest performance: delivers POH numbers; forgiving for instrument training
- !Wing spar fatigue AD (2024-20-XX) now dominates pre-buy: inspection & potential reinforcement kit required
- !Moderate altitude performance: adequate at 5,000 ft DA but marginal above 7,500 ft DA at gross weight
- !Higher fuel burn than Warrior: 9–10 GPH at 75% power; operating costs $2,000–$4,000/year more than Warrior
