Carenado has announced that they are bringing the PA34T Seneca to MSFS 2020. 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 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.
