Cockpit of a Piper PA-42 Cheyenne III

The Piper PA-42 Cheyenne is a twin- engine , low - wing turboprop aircraft produced by the US aircraft manufacturer Piper Aircraft Corporation . The retractable nose wheel and the two main landing gears retracting into the engine nacelles are each fitted with individual tires.

development and construction

The Cheyenne is a turboprop variant of the Piper PA-31 . The Cheyenne I and II still bore the name PA-31 Navajo and were created by lengthening the fuselage and installing a turboprop engine. For this purpose, two Pratt & Whitney PT6As were installed instead of the piston engines and the passenger cell was designed as a pressurized cabin . The variant was named PA-31T . The first flight took place on August 29, 1969 , but difficulties with the stability of the airframe led to significant design changes. Finally, the first machines came to customers in 1974. 823 machines of this type and some sub-variants were sold.

Further refinements such as a T-tail and an extension of the cabin were added later. The machine was then designated as the Piper PA-42 Cheyenne III . The first customer aircraft took off on May 18, 1979 and was in direct competition with the Beech King Air , which had been available since 1974. The engines used were more powerful PT6A, which were flat-rated at 750 shp , so that this power was available up to an altitude of 16,000 feet, an advantage at high airfields and in high outside temperatures ( hot-and-high conditions).

In the last version available from 1984, the Cheyenne IV LS 400 (LS stood for the name of the company Lear Siegler which had since bought Piper and the 400 for the top speed of 400 knots) Garret TPE331 engines with counter-rotating four-blade propellers with an output of 735 kW used. The first flight took place on February 23, 1983. Production was discontinued in February 1993 due to a lack of demand for the production of 192 machines (45 of them LS 400).

The crew consists of one to two pilots, there is space for six to nine passengers.

The "Cheyenne IIIA" was used, for example, at Lufthansa Flight Training as a training aircraft in instrument flight training for pilots of Lufthansa and the German armed forces , until it was replaced by the Cessna Citation Jet CJ1 + .

Incidents

  • On June 28, 1985, the PA-42 with the registration number N542TW collided with a tree shortly before the runway during a night approach to Charlotte Douglas International Airport and crashed. The 27-year-old pilot and his passenger were killed in the accident and the aircraft was destroyed.
  • On October 31, 1992, the PA-42 with the registration number N250TJ crashed during an IFR approach to Walter Field Airport in Grand Junction , Colorado . The FAA determined the improper execution of the approach procedure and the resulting disorientation of the pilot as the cause . The 35-year-old pilot and his two passengers died in the accident. The machine was completely destroyed.
  • Instead of climbing to the instructed altitude after taking off from Nuremberg Airport , a PA-42 went into a steep descent twice in succession on May 5, 2001 and finally hit the ground. The pilot, the only person off board, was killed on impact and the machine was destroyed.
  • On October 18, 2006, the PA-42 with the registration number N121CS took off together with a MiG-21 from Prescott Airport in Prescott , Arizona to take aerial photographs of the MiG-21. During the flight, the PA-42 got into the exhaust of the MiG, whereupon the tail unit of the machine was torn off and the aircraft crashed about sixteen miles northeast of Prescott. The 40-year-old pilot and his four passengers were killed on impact and the plane burned out completely.
  • On January 19, 2009, a PA-42 took off from Frankfurt am Main airport on a transfer flight to Reichelsheim airfield . After the machine had left the control zone via the mandatory reporting point in November in the north of Frankfurt, the air traffic controller suggested that the pilot call the flight information service , which the pilot confirmed. About a minute later, the aircraft hit the rising terrain of the Taunus in the immediate vicinity of the town of Königstein im Taunus . The 51-year-old pilot was killed on impact and the aircraft was completely destroyed.
  • On 5 May 2012, the PA-42 was launched with the registration F-GXES to a medical delivery flight from the airport Saint-Martin - Grand-Case for airport Martinique . About five minutes after takeoff, the plane crashed into the sea. All four occupants - the pilot, a doctor, a nurse and the patient - were killed in the crash.
  • On March 31, 2017, a PA-42 on the way from Manaus Airport to Sorocaba crashed while approaching the destination airport. The two inmates were killed in the crash.
