Heritage and production
The PA-30 Twin Comanche was introduced in 1963, derived from the PA-24-400 Comanche with two 160 hp engines. The C was the last PA-30 variant, in 1969. The PA-39 C/R followed as the final production version. Production was 2000 PA-30s and only 155 PA-39s.
Engines and propellers
Type data for the PA-30/PA-39 series lists Lycoming IO-320-B1A engines and Hartzell HC-E2YL-2 series propellers. A replacement counter-rotating kit uses 70-inch two-bladed props. It is 2 pounds heavier per aircraft and replaces 72-inch props with a 2000 hour / 5 year TBO.
Documents to check
The original Piper Pilot's Operating Manual (761 453) was issued in June 1970. Revisions added a propeller synchrophaser and a fuel pump revision. The FAA-approved flight manual must stay in the airplane. The service manual (753 645) and parts catalog (753 646) cover the PA-39, so confirm the paperwork is current.
Summary written by AI from the source document. Check the original before relying on it. See which parts of Sprinkle are written by AI.
Safety notes
- Piper considers Service Bulletin 1026 compliance mandatory. A failed vacuum pump coupling can cause loss of vacuum instruments. Due before next IFR flight, within ten hours or sixty days.
- The operating manual is not a substitute for flight instruction, and it is not a transition guide from single-engine to multi-engine flying.
- The owner is responsible for airworthiness. Keep the flight manual current, because the approved flight manual governs over other manual information.
