RE: CHECKLISTS, PIMs, AND ATTENTION TO DETAIL

We recently had significant damage to an aircraft due to an incorrect starting procedure. This very fundamental task is reprinted in the following pages from the checklist and Pilot Information Manual (PIM).

It is very important that ALL procedures are to be completed in strict adherence to the written procedures in order to assure the required levels of safety. All pilots are expected to have the necessary knowledge to operate safely such as the start limitations, which are also printed below.

PIPER PA-28-161 WARRIOR III STARTING PROCEDURE

4.13 Starting Engine

a. Starting Engine When Cold

Open the throttle lever approximately 1/4 inch. Turn ON the master switch, alternator switch and the electrical fuel pump.

Move the mixture control lever to the full RICH. Verify the area around the propeller is clear then engage the starter by rotating the magneto switch clockwise. When the engine fires, release the magneto switch, and move the throttle to the desired setting.

Check for proper oil pressure indication.

If the engine does not fire within five to ten seconds, disengage the starter, prime the engine and repeat the starting procedure (priming is accomplished by lifting the switch guard and depressing the momentary electric prime button for the desired time.)

b. Starting Engine When Hot

Open the throttle lever approximately ½ inch. Turn ON the master switch, alternator switch and the electrical fuel pump. Move the mixture control lever to the full RICH. Verify the area around the propeller is clear then engage the starter by rotating the magneto switch clockwise. When the engine fires, release the magneto switch, and move the throttle to the desired setting.

Check for proper oil pressure indication.

c. Starting Engine When Flooded

Open the throttle lever should be full OPEN. Turn ON the master switch and alternator switch, and turn OFF the electrical fuel pump. Move the mixture control lever to idle cut-off. Verify the area around the propeller is clear then engage the starter by rotating the magneto switch clockwise. When the engine fires, release the magneto switch, and advance the mixture and retard the throttle.

Check for proper oil pressure indication.

NOTE: Starter manufacturer recommends starter cranking periods be limited to 10 seconds with a 20 second rest period between cranking periods. Maximum of 6 start periods allowed. If start is not achieved on sixth attempt allow starter to cool for 30 minutes before attempting additional starts.

PIPER PA-28R-201 ARROW III STARTING PROCEDURE

4.13 Engine Start (4.5c)

4.13a. Normal Start – Cold Engine (4.5c)

Open the throttle lever approximately 1/2 inch. Turn ON the alternator and battery master switches, and the electric fuel pump.

Move the mixture control to full RICH until an indication is noted on the fuel flow meter. The engine is now primed. Move the mixture control to idle cut-off, check that the propeller area is clear, and engage the starter by rotating the magneto switch clockwise. When the engine fires, release the magneto switch, advance the mixture control to full RICH and move the throttle to the desired setting. Check the oil pressure.

If the engine does not fire within five to ten seconds, disengage the starter and reprime.

4.13b. Normal Start – Hot Engine (4.5c)

Open the throttle approximately ½ inch. Turn ON the alternator and battery, master switch, and the electrical fuel pump. The mixture control lever should be in idle cut-off. Check that the propeller area is clear, and engage the starter by rotating the magneto switch clockwise. When the engine fires, release the magneto switch, advance the mixture, and move the throttle to the desired setting. Check the oil pressure.

4.13c. Engine Start When Flooded (4.5c)

The throttle lever should be full OPEN. Turn ON the alternator and battery master switches, and turn OFF the emergency fuel pump. The mixture control lever should be in idle cut-off. Check that the propeller area is clear, and engage the starter by rotating the magneto switch clockwise. When the engine fires, release the magneto switch, advance the mixture, and retard the throttle. Check the oil pressure.

NOTE: Starter manufacturer recommends starter cranking periods be limited to 10 seconds with a 20 second rest period between cranking periods. Maximum of 6 start periods allowed. If start is not achieved on sixth attempt allow starter to cool for 30 minutes before attempting additional starts.
