Powerplant
The aircraft is powered by Lycoming O-540 engines, producing 235 BHP at 2575 RPM. It features Hartzell constant speed propellers and has specific oil capacity requirements, with a maximum of 12.0 quarts and minimums for local and cross-country flights.
Fuel System
The Piper PA-23 Apache has a total fuel capacity of 144 gallons, with approved fuel grades of 100LL and 80/87. The fuel burn rate is approximately 22 GPH, and the system includes multiple fuel tanks and pumps.
Performance Metrics
Key performance speeds include a stall speed in landing configuration (VSO) of 62 MPH, a rotate speed (VR) of 80 MPH, and a maximum structural cruising speed (VNO) of 198 MPH. The never exceed speed (VNE) is 249 MPH.
Pilot Tips
The document provides practical tips for pilots, including starting procedures, power settings after takeoff, and recommendations for flap operation. It emphasizes the importance of proper mixture leaning techniques for fuel efficiency.
Safety notes
- Electric fuel pumps must be on for takeoff and landing, and when crossfeeding.
- If the left engine fails after takeoff, manual gear pumping may be necessary.

VMC 80 MPH ✈ Pilot Tips: • Normal cold start should take 3 shots of prime. A hot start should take no prime at all. Under extreme cold, taxi with the carb heat on until its time for the run-up. • After takeoff, reduce power to 24”MP/2400 RPM. Cruise climb at 130 MPH. • Cruise speed 165 kts. • Normal cruise power setting is 19” MP and 2300 RPM. Lean engines to approximately 1450°F. • Range: 850 nm w/ Reserves. • Left engine is the critical engine. • Left engine runs hydraulic pump. If the left engine fails after takeoff, it may be necessary to manually pump the gear up for adequate climb performance. Refer to the POH for the proper procedure. • Flap extension and retraction is very rapid due to the high efficiency of the hydraulic system. Region Flyers recommends extending and retracting flaps incrementally to avoid large changes in required control pressure throughout all phases of flight. • Fuel burn will be greatly affected by proper mixture leaning techniques. Refer to POH for the best technique. Mains 27 PSI Nose 30 PSI
