Parking brake set
Cover the brakes in case aircraft moves forward during start up
Make sure propeller area is clear
How many forms can the engine start up procedure take?

STARTER
ENGAGE
How do we press the primer?
between 3-6 seconds until we see positive fuel flow
To how many rpm do we reduce once we have pushed the starter until the engine starts and release it?
1200 rpm
What do we do to prevent starter damage?
limit starter cranking to 30 second periods
How many minutes of cooling period do we need to allow if the engine does not start at that time?
2 minutes
Do we engage the starter immediately after realizing it?
NO
What checklist do we read after?
AFTER START CHECKLIST
What about after this checklist, when we’ve been cleared?
we will begin the taxi
What do we check after starting the first engine?
oil pressure green within 30 seconds
ammeter charging
fuel flow in green
positive gyro pressure on the operative engine
Red ball is nor showing (indication of gyro pressure failure if it is still there)
What’s the start up in cold weather operation?
done in cold weather, engines are quite cold and could cause first explosions inside the cylinders
What does the instructor do before starting up, in the pre-flight inspection?
manually turn the propellers of each engine 3 times, so that any fluids in the engine are removed
What’s the Start up sequence in cold weather operation?
11 steps
FUEL SELECTOR

STARTER
ENGAGE
What do we do after engine has started?
Reduce throttles to obtain 1200 RPM
What do we do if the engine is not running smoothly?
If necessary, press the PRIMER in a few times until it does so
then switch the fuel pump off
What do we read after?
AFTER START CHECKLIST, then clearance to taxi
What’s the engine start up with a hot/flooded engine?
Almost opposite of previous procedure. When temp OAT is high or when we have flooded the engine
How many steps does this checklist have?
9

What do we do if the engine fires?
2 steps
THROTTLE
RETARD
MIXTURE
ADVANCE SLOWLY
What checklist do we read after?
AFTER START CHECKLIST, and after request permission to taxi
What’s the engine start up with external power?
cases where there is insufficient battery remaining to turn the propeller
necessary to have a piece of maintenance equipment connected in the following operation
What do we need to make sure of?
5 things
ELECTRICAL EQUIPMENT
OFF
MASTER
OFF
Connect External output of the Piper External Power (PEP) to…?
acft’s external power socket located on the fuselage.
Check both have same voltage
When the plug is inserted, electrical system is ON
NORMAL STARTING TECHNIQUE
PROCEED
START RIGHT ENGINE
ONCE ENGINE HAS STARTED
MASTER ON
RIGHT ALTERNATOR ON
THEN WE WILL START LEFT ENGINE
THEN DISCONNECT EXTERNAL POWER AND PROCEED WITH THE OTHER ENGINE
What should we do once the right engine has started under this procedure?
reduce power to the lowest possible RPM to reduce sparkling
What types of operation with external power do we have?
Depending on the PA34, we could do it with MASTER ON or OFF, the way to check is by connecting external power, then with MASTER OFF, turn ON all radio equipment, if it turns on, then proceed with the start up with MASTER OFF, if however the radio equipment does not turn on, then we will proceed with the start up sequence with MASTER ON
DO NOT ATTEMPT FLIGHT
There is no indication of alternator output
After this we…
perform after start checklist, and after we will request permission to taxi
