The Piper PA-34 Seneca is a twin-engined light aircraft , produced in the United States by Piper Aircraft . It has been in non-continuous production since 1971. The Seneca is primarily used for personal and business flying as well as multi-engine class rating flight training .
21-798: The Seneca was developed as a twin-engined version of the Piper Cherokee Six . The prototype was a Cherokee Six that had wing-mounted engines installed, retaining its nose engine. The prototype was flown as a tri-motor aircraft in the initial stages of the test-flying program. With the decision to abandon the three-engined design tested on the PA-32-3M, the PA-34 was developed as a twin-engined aircraft. The prototype PA-34-180 Twin Six, registered as N3401K , first flew on 25 April 1967. The prototype had two 180 hp (134 kW) Lycoming O-360 engines,
42-548: A 1972 model, the PA-34-200 Seneca is powered by a pair of Lycoming IO-360-C1E6 engines. The righthand engine is a Lycoming LIO-360-C1E6 engine variant, the "L" in its designation indicating that the crankshaft turns in the opposite direction, giving the Seneca counter-rotating engines. The counter-rotating engines eliminate the critical engine limitations of other light twins and make the aircraft more controllable in
63-507: A fixed nosewheel landing gear and a Cherokee Six vertical tail. The second prototype flew on 30 August 1968, still with the 180 hp (134 kW) Lycomings but had retractable landing gear and a taller vertical tail. During development flying the wingspan was increased by two feet. The third prototype was closer to the production standard and flew on 20 October 1969; it was fitted with 200 hp (149 kW) Lycoming IO-360-A1A engines. Certified on 7 May 1971 and introduced in late 1971 as
84-484: A one-piece windshield and a bare metal instrument panel instead of one covered with a removable plastic fascia. Because of the raised zero-fuel weight and the raised maximum take-off weight, the Seneca III has the highest useful load of all the PA-34 variants. Some later models have electrically-actuated flaps. More than 930 Seneca IIIs were built; the last 37 Seneca IIIs built had a 28-volt electrical system rather than
105-529: Is a series of single-engine, fixed landing gear , light aircraft manufactured in the United States by Piper Aircraft between 1965 and 2007. The PA-32 is used around the world for private transportation, air taxi services, bush support, and medevac flights. The PA-32 series was developed to meet a requirement for a larger aircraft than the four-seat Piper PA-28 Cherokee . The first prototype PA-32 made its initial flight on December 6, 1963, with
126-580: Is available in both naturally aspirated, fuel injected IO-360 models and turbocharged TSIO-360 versions. It is also available in both left and right hand rotation versions for use on twin-engined aircraft. There was no carbureted version of this engine, which would have been designation O-360 , therefore the base model is the IO-360 . The IO-360 was first certified by the Federal Aviation Administration on 15 May 1962 to

168-846: The Piper Lance . This was the earliest aircraft in the Piper Saratoga family, Piper's luxury, high-performance single line. Piper's transition to tapered wings for the Cherokee series resulted in a new wing for the PA-32 series, as well. The tapered-wing version of the Cherokee Six was named the Saratoga and debuted in 1980. After the General Aviation Revitalization Act of 1994, production of

A typical Seneca III with air conditioning and deicing equipment has a useful load of 1,377 lb (625 kg). In 1994, the "New" Piper Aircraft company introduced the Seneca IV, having achieved certification on 17 November 1993. This model
210-687: The 2014 model is 1,331 lb (604 kg) but typically is 1,134 lb (514 kg) when the aircraft is equipped with air conditioning, deicing equipment and co-pilot instruments. From 1975 the Seneca was built under licence in Brazil by Embraer as the EMB-810. The PA-34-200T was produced as the EMB-810C Seneca (452 built) and the PA-34-220T as the EMB-810D (228 built).

The turbocharged TSIO-360 series was first certified on 11 October 1966 to the Federal Aviation Regulations Part 33 standard effective February 1, 1965, as amended by 33–1. This series is manufactured under Production Certificate No. 7, except

The engine
273-599: The PA-34-220T Seneca III was introduced, having completed certification on 17 December 1980. The change in model designation reflected an engine upgrade. Continental TSIO-360-KB engines were used which produced 220 horsepower (165 kW), although only rated as such for five minutes and then dropping to 200 hp (149 kW). The horsepower increase, with the new engines limit of 2800 rpm (up from 2575 rpm), combined for much improved climb and cruise performance. The new aircraft also incorporated
294-490: The counter-rotating engine arrangement of the earlier Seneca I. The Seneca II also introduced optional "club seating" whereby the two center-row seats face rearwards and the two back seats face forward allowing more legroom in the passenger cabin. A total of 2,588 Seneca IIs were built. Gross weights are 4,570 lb (2,070 kg) for takeoff and 4,342 lb (1,969 kg) for landing, with all weight in excess of 4,000 lb (1,800 kg) required to be fuel. In 1981,
315-489: The event of a shut down or failure of either engine. A total of 934 Seneca models were built, including one prototype. The early Seneca models have a maximum gross weight of 4,000 lb (1,810 kg), while later serial numbers allowed a takeoff weight of 4,200 lb (1,910 kg). Responding to complaints about the aircraft's handling qualities, Piper introduced the PA-34-200T Seneca II. The aircraft
336-514: The nose between the cockpit and the engine compartment and a large double door in the back for easy loading of passengers and cargo. On 27 May 1966, Piper obtained FAA type certification for a 300 hp (220 kW) version, designated as the PA-32-300. It was offered by the company as a 1967 model. The 1975 addition of retractable landing gear resulted in the first of the PA-32R series,
357-503: The panel to the headliner, and an improved engine variant, the Continental TSIO-360-RB , fitted with an intercooler , was used. The Seneca V's gross weights remain the same as the Seneca III and IV at 4,750 lb (2,155 kg) for takeoff and 4,513 lb (2,047 kg) for landing, therefore, with all of the added features, the useful load is reduced by about 200 lb (91 kg). The standard useful load for
378-463: The retractable-gear Saratoga resumed in 1995. A fixed-gear PA-32 was reintroduced in 2003 as the Piper 6X and the turbocharged 6XT. Sales of the 6X and 6XT models did not meet expectations and production ceased in late 2007. Piper built a prototype PA-32-260 with IO-360 engines mounted on the wings. The trimotor aircraft was the proof-of-concept aircraft for the twin-engined, retractable-gear version of
399-522: The type being publicly announced in October 1964, with Federal Aviation Administration (FAA) aircraft_type certification following on March 4, 1965. The first production aircraft was the 260 horsepower (190 kW) PA32-260 Cherokee Six, a significantly modified six-seat (or seven-seat) development of the PA-28 Cherokee . The Cherokee Six and its successors feature a baggage compartment in
420-454: Was certified on 18 July 1974 and introduced as a 1975 model. The new model incorporated changes in the aircraft's control surfaces, including enlarged and balanced ailerons, the addition of a rudder anti-servo tab, and a stabilator bobweight. The "T" in the new model designation reflected a change to turbocharged, six-cylinder Continental TSIO-360E or EB engines for improved performance, particularly at higher altitudes. The Seneca II retained
441-470: Was similar to the Seneca III offering minor improvements, such as a streamlined engine cowl for increased cruise performance. It continued to use the counter-rotating Continental TSIO-360-KB engines and gross weights remained unchanged. A total of 71 Seneca IVs were built. Certified on 11 December 1996, the Seneca V was put into production as a 1997 model year. Again the cowls were redesigned for increased performance, several cockpit switches were relocated from
