This enhanced version of the well-spoken Piper Navajo is equipped with new PT6A engines and wider fuselage. The Cheyenne I has room for four passengers in a setup club seating and an additional seat facing the lado.Apesar to possess relatively ancient architecture, the PA-31T1 model has very good safety records due to powerful engines and ease of maintenance. With a rear luggage compartment of 0.62 m³ (22 ft³) and a front compartment of 0,56 m³ (20 ft³), Cheyenne can carry up to 227 kg luggage. This corresponds to at least one piece of luggage of 15kg per person.
