ENGINE:
Lycoming 4 cylinder 0-360,180 HP @ 2700 RPM, air cooled, direct drive, horizontally opposed, normally aspirated. Major accessories include starter, belt driven alternator, dual magnetos, and a vacuum pump. Oil capacity is 8 quarts maximum; 6 quarts minimum required for flight.
PROPELLER:
Sensenich, two blades, fixed pitch, 76 inch all metal propeller.
BRAKES:
Hydraulic discs located on each of the two main landing gear provide braking. Two master cylinders, one behind each brake pedal on the pilot's side control each individual wheel. The co-pilot's brake pedals are mechanically connected linked to the pilots brake pedals.
FLAPS:
The flaps are electrically operated single slot type. Flaps are extended or retracted by positioning the wing flap switch lever to the desired flap deflection position. The flap switch lever has stops at the 10 °and 20° positions. A scale and pointer indicates the flap travel in degrees. Total flap travel is 30 degrees.
FUEL SYSTEM:
Fuel is carried in two wing tanks with a total capacity of 54 gallons. A total of 50 gallons usable fuel is available. The fuel selector valve is labeled with the total useable fuel. Fuel is gravity fed to the engine. The fuel selector valve has four positions: Both, Left, Right, Off. The fuel selector should be set to Both for all takeoffs and landings. Each fuel tank has one sump. The entire fuel system can be sumped by pulling on the fuel strainer knob located under the access panel on the right side of the engine cowling.
ELECTRICAL SYSTEM:
Electrical energy is supplied by a 28 volt direct current system powered by an engine driven alternator. A 24 volt battery is located left forward side of the firewall. The ammeter indicates the charging rate, in amperes, of current supplied from the alternator to the battery. The ammeter will show a discharge when the alternator is not functioning or the electrical load exceeds the output capacity of the alternator. Electrical circuits are protected by circuit breakers mounted on the instrument panel.

STEEP POWER TURNS:
Two 90° or one 180° turns. Set power to 2100 RPM and adjust airspeed to 90 KIAS. Roll into a bank angle of 50°. Begin applying back pressure and add 100 to 200 rpm passing through 30° angle of bank. Begin roll out 15° -:20° before assigned heading and relax back pressure, reduce power to 2100 RPM passing 300angle of bank. Maintain a constant altitude, airspeed, and roll out on the assigned heading.
SLOW FLIGHT:
Two 90° or one l80°clearing turns. Apply carburetor heat on and set power to 1500 RPM. Increase pitch attitude to maintain altitude and decelerate to 50 KIAS. Add flaps as desired. Increase power and adjust pitch to maintain altitude and airspeed. Maintain airspeed with pitch control, altitude with power, and a constant heading with an emphasis on rudder control. To recover apply full power, carburetor heat off, lower the nose, select the flaps up in increments while accelerating to cruise.
APPROACH TO LANDING STALL:
Two 90° or one 180°clearing turns. Apply carburetor heat on and set power to 1500 RPM. Below 85 KIAS select full flaps. Establish the aircraft in a landing attitude.
Set the power to idle. Hold the landing attitude until obtaining the stall buffet or full stall.
Recover by relaxing back pressure to hold a climb attitude. Select full power, carburetor heat off, retract flaps to 20°. As aircraft accelerates, continue raising the flaps to O° after passing through 60 KIAS.
TAKEOFF/DEPARTURE STALL:
Two 90° or one 180° clearing turns. Apply carburetor heat on and set power to
1500 RPM. Slow to 60 KIAS. Turn carburetor heat off. Increase pitch to slightly higher than climb attitude while increasing to full power. Hold this attitude by increasing elevator back pressure until obtaining stall buffet or stall. To recover, relax the back pressure to decrease the pitch to a climb attitude while accelerating to climb airspeed. If the aircraft drops a wing during the maneuver, it is caused by lack of rudder coordination. To pick up the wing Do Not Use aileron. Use the rudder to pull the wing up.
MAXIMUM PERFORMANCE TAKEOFF OVER AN OBSTACLE:
Select 100 flaps, hold brakes, apply full power smoothly, release brakes: Accelerate to 55 KIAS, rotate and climb out at 57 KIAS until obstacle is cleared. Lower the nose, accelerate, to Vy, raise the flaps after passing through 60 KIAS. Accelerate to Vy 73 KIAS and after passing through 1000 feet climb at 80 - 85 KIAS cruise climb airspeed.
SHORT/SOFT FIELD TAKEOFF:
Select 10° flaps, yoke positioned full aft, advance power to full, do not hold brakes and establish a takeoff attitude. Let the airplane fly itself into the air, once airborne and in ground affect lower nose to accelerate to climb speed.
NORMAL LANDING:
Select carburetor heat on. Set power to 2000 RPM in the pattern maintain 85 KIAS. At the abeam position reduce power to 1500 RPM, add 10° flaps ,adjust airspeed to 75 KIAS. Base leg flaps to 20° airspeed to 70 KIAS. On final, set flaps to 30° maintain airspeed 60 - 65 KIAS. In the landing flare reduce power to idle, touch down on the mains holding the nose wheel off until the elevator loses effectiveness.
SHORT FIELD LANDING:
Select carburetor heat on. Set power to 2000 RPM in the pattern maintain 85 KIAS. At the abeam position, reduce power to 1500 RPM, add 10° flaps adjust airspeed to 75 KIAS. Base leg flaps to 20° airspeed to 70 KIAS. On final, set flaps to full, maintain airspeed 60 KIAS. In the landing, flare reduce power to idle, touch down on the mains first, lower the nose to the runway, retract the flaps, apply maximum braking without skidding the tires.
SOFT FIELD LANDING:
Select carburetor heat on. Set power to 2000 RPM in the pattern maintain 85 KIAS. At the abeam position reduce power to 1500 RPM, add 10oflaps adjust airspeed to 75 KIAS. Base leg flaps to 20oairspeed to 70 KIAS. On final, set flaps to full, maintain airspeed 60 KIAS. In the landing flare reduce the power to slightly above idle, attempt to hold aircraft off runway as long as possible by landing on the mains while increasing back pressure until elevator losses its effectiveness. Use no brakes, power should be reduced to idle after landing, during roll-out.
GO AROUND:
Power to full throttle, carburetor heat off, establish a climb attitude, immediately, but slowly retract flaps to 20°, retract flaps to 10° passing through 55 KIAS, retract flaps to 0° passing through 73 KIAS. Accelerate to Vy ( 73 KIAS) and climb to pattern altitude.
