Overview 2

The original two-seat Piper Cherokee 140, with a 140 hp Lycoming engine, was announced in February 1964, primarily as a sporting and training aircraft to replace the Piper Colt, but equally suitable for general transportation use. It received FAA Type Approval on 14 February 1964.

In the autumn of 1965, the Piper Cherokee 140 was superseded by the Cherokee 140-4, which is convertible into a full four-seater, for four adults. The conversion kit included two separate upholstered seats, which could be installed with wing nuts on the raised rear floor over the main spar, two Back cushions, seat belts and attachment fittings.

To cater for this additional payload and to improve performance, the engines of all-new Piper Cherokee 140-4’s were rated at 150 hp, whether or not they were equipped as four-seaters. Conversion of existing Piper Cherokee 140’s to four-seat use was accomplished by installing the kit and by modifying the propeller to permit the Lycoming O-320 engine to produce 150 hp.

During 1968 the Piper Cherokee 140-4 was also available in Custom, Executive and Sportsman versions, and with four optional electronic packages.

Standard — Basic model with dual controls.

Custom — As basic model, with the addition of Piper TruSpeed Indicator, instrument panel light, cabin dome light, navigation, landing and taxi lights, rotating beacon, radio shielding, sensitive altimeter, lighter, coat hooks, step, full flow oil filter and Piper AutoFlite wing leveling stability system, adding 12 lb (5.5 kg) to basic empty weight.

Executive — As Custom model, with the addition of blind-flying instrumentation, arranged T configuration, clock, outside air temperature gauge, gyro air filter and vacuum pump.

Sportsman — As Executive model, with the addition of Piper electric trim, external power, and AutoNav tracking for AutoFlite.

Electronic Group B — Same as Group A, with addition of ADF-31 automatic direction finder, adding total of 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 VOR/ILS localizer converter indicator and Piper marker beacon, adding a total of 33 lbs (15 kg) to basic empty weight.

Most of the items covered under model and electronic group listings were also available individually.
