Piper PA-28 Cherokee Series ²

Circa 1966, the Cherokee was a low-cost all-metal low-wing monoplane with a non-retractable tricycle landing gear. The aircraft was available in 2/4-seat, 4-seat and 6/7-seat versions. A floatplane version was also in production.

Only 1,200 parts went into the manufacture of the Cherokee. Its predecessor, the four-seat high-wing Piper Tri-Pacer used 1,600 parts in its manufacture. The first production Cherokee flew on 10 February 1961, and production was at the rate of 14 aircraft per day in the summer of 1966. A total of 5,219 Cherokees had been built by 1 January 1966.

Models available during 1966 were the Cherokee 140-4 (2/4-seat), Cherokee C 150, 160 and 180 (four-seat), Cherokee 235B (four-seat), and the Cherokee Six (6/7-seat). Descriptions of the PA-28-150, PA-28-160, and the PA-28-180 are presented below.

As part of a continuing research program, Piper tested two Cherokees with a controllable-pitch propeller and retractable landing gear respectively in 1966.

Piper PA-28 Cherokee C Series ²

During 1966, three basic versions of the Piper PA-28 Cherokee C were in production.

• Piper PA-28-150 — 150-hp Lycoming O-320-A2A engine. Prototype flew for the first time on 14 January 1966. FAA type approval 2 June 1961.
• Piper PA-28-160 — 160-hp Lycoming O-320-D2A engine. Prototype flew for the first time on 20 September 1960. FAA Type Approval 31 October 1960.
• Piper PA-28-180 — 180-hp Lycoming O-360-A3A engine. Wheel fairings standard. Prototype flew for the first time on 6 February 1961. FAA Type Approval 3 August 1962.

Each of these basic Cherokee models was available in four different forms, with varying standards of equipment, as follows:

• Standard Cherokee — Basic model with dual controls.
• Custom Cherokee C — As basic model, with addition of Piper TruSpeed Indicator, instrument panel light, cabin dome light, navigation and taxi light, rotating beacon, radio shielding, sensitive altimeter, lighter, coat hooks, step, full flow oil filter and Piper AutoFlite wing stability levelling system, adding 12 lbs (5.5 kg) to basic empty weight.
• Executive Cherokee C — As Custom model, with addition of blind-flying instrumentation, clock, and vacuum pump. Piper AutoControl in place of AutoFlite, adding 25 lbs (11.5 kg) to basic empty weight.
• Sportsman Cherokees C — As Executive model, with addition of Piper electric trim, external power, and course selector on AutoControl, adding 35 lbs (16 kb) to basic empty weight.

Each of the above versions could be fitted with one of four electronic packages, as follows:

• Electronic Group A — Comprises Mk III Omnigator, 90-channel VHF transceiver plus 100-channel VOR/ILS nav indicator, cabin speaker, headset, microphone and antennae, adding 10 lbs (4.5 kg) to basic empty weight.
• Electronic Group B — Same as Group A, with the addition of ADF-31 automatic direction finder, adding 18 lbs (8 kg) to basic empty weight.
• Electronic Group C — Same as Group B, with the addition of Mk 12 series 360-channel VHF transceiver plus 100-channel VOR/ILS nav receiver, VOA-4/ILS localizer converter indicator and Piper marker beacon, adding total of 33 lbs (15 kg) to basic empty weight.
• Electronic Group D — Same as Group C, but with Mk 12 series 90-channel the VHF transceiver instead of Mk III Omnigator, and addition of VOA-5 VOR/ILS localizer converter indicator with glide-slope indication, UGR glide-slope receiver and UDI DME with ground speed indication, adding total of 53 lbs (24 kg) to basic empty weight.

Most items covered under model and electronic group listings were available individually. Other optional extras included Palm Beach external finish, stainless steel control cables, mixture control indicator, T-12 series ADF, KX-160 series radio, fire extinguisher, toe breaks and heated pitot tube.

All versions of the Cherokee could also be fitted with the new Piper AutoFlite automatic stability system. Weighing less than 4 lbs (1.8 kg), this incorporates in the amplifier an electrical rate-gyro with a zero threshold which senses both azimuth changes in wing-down condition, and operates in the ailerons as required for stability. Automatic pitch control is unnecessary on the Cherokee.

The Piper PA-28-180 Cherokee was also available in seaplane form as the PA-28S-180 with Edo Model 89-2000 floats, having received FAA Type Approval in this form on 10 May 1963.

All versions of the Cherokee could be fitted with low-drag quickly-detachable Sorensen spray-gear for agricultural duties. Available in kit form, the spray-gear consists of 110 US gallon (416 liter) glass-fiber belly tank, ½-in pump, pipes and boom with openings for 17 nozzles of five different types.
