The Piper PA-30 Twin Comanche is a twin-engine aircraft designed and manufactured by the Piper Aircraft Corporation. The aircraft was the first production twin available to the general public when it was first introduced in 1965. The Twin Comanche was designed to meet the need for a larger and faster personal aircraft than the single-engine aircraft of its time.

The Twin Comanche was designed to provide a reliable and affordable twin-engine aircraft for the general aviation market. It was intended to supplement Piper's popular single-engine product line and to compete with other aircraft manufacturers' twin-engine offerings. The Twin Comanche was designed to be easy to fly and maintain, with a cabin large enough for four adults. The aircraft was powered by two horizontally opposed engines, each producing 180 horsepower. It had a maximum take-off weight of 5,100 pounds and a cruising speed of 148 knots.

The Twin Comanche was well-received by the aviation community and quickly became a popular choice for private pilots. Over the course of its production, more than 3,000 Twin Comanches were built. The aircraft became known for its good performance and safety record and was used for a variety of missions, including personal, business and charter flights.

Despite its popularity, the Twin Comanche has had some issues with safety over the years. One of the most serious was the problem of propeller feathering, where the blades of one engine's propeller would not spin freely when the other engine was shut down. This could lead to a sudden loss of power and cause an engine to quit in mid-flight. To address this issue, Piper redesigned the propeller feathering system for the Twin Comanche in 1968.

Other safety issues have included engine fires and fuel leaks. In the early 1970s, a series of engine fires were attributed to the aircraft's fuel system. To address this issue, Piper redesigned the fuel system, adding an extra fuel pump and an improved fuel line system. Additionally, a number of fuel leaks were reported due to issues with the fuel system's seals, which led to a redesign of the fuel system in 1976.

Despite these issues, the Piper Twin Comanche has remained a popular choice for private pilots and charter operators. Its combination of power, range, and reliability has made it a popular choice for personal and business flights, and it is still in wide use today. With more than 3,000 aircraft built, the Twin Comanche is one of the most successful aircraft ever produced by Piper Aircraft.
