While the Arrow might look like a Cherokee and the design is almost identical, it does differ in being a retractable undercarriage four-seater powered by a 180 or 200 hp engine. Sales began slowly in 1967, gaining impetus when the 200 hp version was introduced two years later. In 1969 Piper made available an optional PA-28-200R Cherokee Arrow with a 149kW IO-360-C1C engine. The 1976 Arrow II evolved from the original 180 hp model built and introduced in 1967 with a useful load of 1120 lbs. 20 more hp were added in 1969, upping the useful load to 1119 lbs. and the service ceiling by 1700 ft. to a maximum of 17,000. Improvements came year by year with significant changes in 1980 (longer fuselage and wider door), 1977 the new wing with tapered outer sections (as the Arrow II) and in 1979 a T-Tail.
