This article delves into the fascinating story of the Piper PA-24 Comanche, exploring its design, evolution, and the reasons behind its enduring appeal.

A Vision of Performance: Design and Development

The Piper PA-24 Comanche was conceived as a modern, high-performance aircraft, a departure from Piper’s earlier fabric-covered designs. Its all-metal, low-wing monoplane construction, coupled with a semi-monocoque fuselage and retractable tricycle landing gear, set it apart. The design emphasized aerodynamic efficiency and structural integrity, aiming for both speed and durability.

The journey of the Comanche began in 1956 with the construction of two prototypes. The first production model, powered by a 180 horsepower Lycoming O-360-A1A engine, took to the skies in October 1957. Piper soon followed with a more powerful variant in 1958, the PA-24-250, featuring a 250 horsepower Lycoming O-540-A1A5 engine. This model, initially considered for a separate PA-26 designation, ultimately retained the PA-24 nomenclature, signifying its lineage within the Comanche family.

Further advancements came in 1964 with the introduction of the formidable 400 horsepower PA-24-400. The subsequent year saw the PA-24-250 superseded by the PA-24-260, which boasted a 260 horsepower Lycoming IO-540D or E engine. For those seeking even greater performance at altitude, a turbocharged version of the 260, equipped with a Rajay turbocharger, became available in 1970.

The production of the Comanche series, however, met an abrupt end in 1972. The devastating Susquehanna River flood, caused by torrential rains from Hurricane Agnes, inundated Piper’s manufacturing plant in Lock Haven, Pennsylvania. The floodwaters destroyed not only existing airframes and parts but also much of the specialized tooling required for Comanche production. Rather than undertaking the costly and time-consuming effort to rebuild, Piper made the strategic decision to discontinue the Comanche and its twin-engine counterpart, the Twin Comanche. The company instead focused its resources on newer designs already in production at its Vero Beach, Florida facility, such as the PA-28R-200 Arrow and the twin-engined PA-34 Seneca.

The Many Faces of the Comanche: Exploring its Variants

The Piper PA-24 Comanche was produced in several distinct variants, each offering a unique blend of performance and features, catering to a wide range of pilot needs. These variations contributed to the Comanche’s versatility and enduring popularity.

The Original: Comanche 180

The initial iteration, the PA-24-180, set the stage for the Comanche’s success. It was powered by a 180 horsepower Lycoming O-360-A1A engine and featured a distinctive swept tail, a laminar flow airfoil for enhanced aerodynamic efficiency, and an all-flying stabilator. The Comanche 180 typically carried 60 US gallons of fuel, offering a respectable range. Its manually actuated flaps, controlled by a ‘Johnson bar’ similar to the Piper Cherokee, were a characteristic of these early models. With cruise speeds ranging from 116 to 139 knots, and a full-fuel payload of 715 pounds, the 180 was a capable and efficient aircraft for its time. Over 1,100 units of this foundational model were built, establishing the Comanche’s reputation.

The Workhorse: Comanche 250

Introduced in 1958, the PA-24-250 quickly became the most prolific single-engine Comanche variant. Equipped with a 250 horsepower Lycoming O-540 engine, it boasted a top cruise speed of 160 knots. While most 250s utilized carbureted engines, a select few were fitted with fuel-injected versions, offering improved fuel management. Early 250s shared the manual flap system and 60-gallon fuel capacity of the 180, but by 1961, auxiliary fuel tanks increasing total capacity to 90 US gallons became an option, significantly extending its range. The 1962 model year brought the convenience of electrically actuated flaps as a standard feature. The sheer number of Comanche 250s produced, totaling over 2,500, speaks volumes about its success and utility.

The Powerhouse: Comanche 260 and 260TC

Beginning in 1965, Piper introduced a series of 260-horsepower variants, further enhancing the Comanche’s performance envelope. These included the PA-24-260, 260B, and 260C, culminating in the turbocharged 260TC. Over 1,000 aircraft from the 260 line were sold, underscoring their appeal.

The 260 models offered increased gross weights and payloads. The 260B, for instance, featured a slightly longer propeller spinner and a third side window, along with the option for six seats, though the rear seats were best suited for smaller adults or children. The 260C introduced a distinctive ‘Tiger Shark’ cowling, an increased maximum gross weight of 3,200 pounds, cowl flaps, and an aileron-rudder interconnect for improved handling. Its extended propeller shaft also subtly shifted the center of gravity forward, accommodating the increased weight and seating capacity. With a useful load of 1,427 pounds, the 260C offered impressive carrying capability.

The PA-24-260TC, introduced in 1970, was a significant development, featuring a Lycoming IO-540-R1A5 engine with dual Rajay turbochargers. This variant was certified for flight up to 25,000 feet, with a turbo critical altitude of 20,000 feet, allowing for true airspeeds of up to 223 mph. The ‘boost’ handle in the cockpit, controlling the manual wastegate, gave pilots precise control over the turbochargers, effectively providing a ‘second throttle’ for high-altitude performance.

The Rare Beasts: PA-24-300, PA-24-380, and Comanche 400

While not mass-produced, several experimental and limited-production variants showcased the Comanche’s potential for even greater power. A single PA-24-300 was modified in 1967 with a 300 horsepower Lycoming engine for trials, though it never entered production. Similarly, two PA-24-380 prototypes were built in 1961, featuring 380 horsepower Lycoming IO-720-A1A engines and three-bladed propellers.
