DH 60 Moth Checklist

Exterior Preflight

1) Inspect airframe for airworthiness

2) Verify adequate fuel and oil aboard

Start Check

1) Fasten Safety Harness

2) Turn fuel tap ON

3) Set Altimeter to field elevation.

4) With wheels CHOCKED and Switches OFF, have your Mechanic pull the propeller through four or five times.

5) On the Mechanic’s command, reach around windscreen and turn Switches ON. The engine WILL START when the Mechanic pulls the propeller through with the Switches ON.

6) Verify Oil Pressure within 60 seconds

7) Allow the engine to warm up for 3 – 5 minutes depending on conditions

8) If a magneto check is desired, verify that the wheels are chocked and have the Mechanic hold the tail. Remember, THERE ARE NO BRAKES.

9) When ready to taxi, have the Mechanic remove the chocks.

Pre-Takeoff Check

1) Check fuel gauge to verify adequate fuel aboard.

2) Recheck that the Altimeter reads field elevation

3) Set the Elevator Trim for takeoff

4) Check Elevator, Rudder, and Ailerons for freedom of movement and that they move in the proper direction.

5) Check the area to insure that there is no conflicting traffic. Turn into the wind and smoothly open the throttle to full power. As airspeed permits, raise the tail and allow the plane to fly off in a tail-low attitude. Best rate of climb speed is approximately 55 mph. Normal climb speed is between 60 – 70 mph.

Cruise

Normal cruise power is 1800 rpm with either the Cirrus or Gipsy engine. For maximum fuel efficiency, De Havilland recommends a true airspeed of 79 mph in Cirrus powered airplanes and 76 mph in Gipsy powered airplane.

Descent

Descents can be made with power off or power on. If making a power on descent, do not exceed 162 mph indicated airspeed. Do not over-speed the engine. Maximum RPM is 2000 for the Cirrus engine and 2100 for the Gipsy engine.

Landing

1) Overfly the field to determine wind direction.

2) Enter the downwind leg at cruise power.

3) Abeam the touchdown point, close the throttle. Trim to maintain no less than 60 mph until established on final approach.

4) On final, slow to final approach speed.

If Autoslots are installed, maintain at least 50 mph until beginning the flare.

If Autoslots are NOT installed, maintain at least 55 mph until beginning the flare.

After Landing

1) When the aircraft has slowed to a safe speed, exit the landing area.

2) When you have reached your parking area, allow the engine to cool at idle (600 – 650 rpm) for at least 90 seconds before turning the Switches to OFF.

3) Reset the trim lever to the index position.

4) When the propeller has stopped, signal the Mechanic to chock the wheels or exit the airplane and chock them yourself. DO NOT LEAVE THE AIRPLANE UNCHOCKED.

5) If the airplane is not to be flown again, arrange for it to be tied down.

6) Document any mechanical discrepancies encountered in the aircraft Logbook.
