Checklist |
| Engine Failure During Takeoff Run
|
| •Throttle: Idle
|
|
Prevent becoming inadvertently airborne, and stop on
the remaining runway.
Don't adjust the fuel selector because this would
distract from maintaining runway centerline.
| | •Brakes: Apply
|
Maintain runway centerline, then exit runway when
safe but before aircraft comes to a halt.
| | •Flaps: Retract
| | •Mixture: Idle/Cut-off
| | •Ignition Switch: Off
|
|
•Call: Tower, declare engine failure,
request assistance/towing.
|
Do not try to restart the engine.
| | •Master: Off
|
|
| Engine Failure Immediately After Takeoff
|
| •Airspeed: Best Glide
| by pitching forward
|
Establish best glide speed
(when flaps up 65 KIAS,
when flaps down 60 KIAS)
to maximize landing/ditching options.
|
| •Mixture: Idle/Cut-off
|
•Below 800 ft AGL,
use field/road within ±45° lateral;
•Above 800 ft AGL,
return to airport.
|
Prevent the engine from restarting and
catching fire.
| | •Fuel Selector: Off
| | •Ignition Switch: Off
|
|
•Call: Tower, declare EMERGENCY, engine failure,
and intentions.
|
Do not try to restart the engine.
|
| •Flaps: As Required
|
Base: 10°;
Final: 20°;
Short final: 40°
|
Once flaps are lowered, you are committed
to landing.
| | •Master: Off
|
| Flaps won't operate when master power is off.
|
|
| Engine Failure During Flight
|
| •Airspeed: Best Glide
| by pitching forward
|
Establish best glide speed
(when flaps up 65 KIAS,
when flaps down 60 KIAS)
to maximize landing/ditching options.
|
| •Throttle: Full
|
|
Trying to restore engine power. Immediately
counteract any obvious cause (icing, excessively
lean mixture, fuel starvation).
Using a different setting on the fuel selector
may counteract a problem with the fuel system.
|
| •Carburetor Heat: On
|
| •Fuel Selector: Different
|
| •Mixture: Rich
|
| Flow check
| Try to identify the cause of power loss.
|
| •Primer: In and Locked
|
|
If the primer is left open and is leaking fuel,
the engine may catch fire when restarted.
|
| •Ignition:
|
propeller restarting: Both
propeller stopped: Start
|
The previous actions may already have allowed
the engine to restore power without requiring
a restart.
|
|
| Engine Fire During Start on Ground
|
| •Ignition: Start
| Continue cranking
|
Trying to get a start which would suck flames
and accumulated fuel through the carburetor
and into the engine.
|
| If engine starts:
|
In all cases, do not try to restart the engine
but call for assistance, inspect, and repair
damage.
| | •Ignition: Both
| | •Power: 1700 RPM
| | •Engine: Shut Down
|
| If engine fails to start:
| | •Ignition: Start
| Continue cranking
| | •Throttle: Full
| | •Mixture: Idle/Cut-Off
| | •Master: Off
| Secure engine
| | •Ignition Switch: Off
| | •Fuel Selector: Off
|
| Obtain a fire extinguisher, and put out engine fire
|
|
| Engine Fire in Flight
|
| •Mixture: Idle/Cut-Off
|
|
Stop the engine to prevent further development
of the fire.
| | •Fuel Selector: Off
| | •Master: Off
| | •Cabin Heat and Vent: Close
| Overhead vents are OK.
| Prevent smoke and fumes from entering the cabin.
| | •Airspeed: 100 KIAS
|
|
Trying to establish an air flow that will extinguish
the flames.
|
| Execute Forced Landing
|
|
| Wing Fire in Flight
|
| •Navigation Light: Off
|
|
Trying to remove any ignition source for the remaining
fuel.
| | •Strobe: Off
| | •Pitot Heat: Off
|
| •Fuel Selector: Opposite wing on fire
|
Trying to prevent fire from reaching through the
fuel system to the engine or other tank.
| | •Power: Idle
|
|
Trying to establish an air flow that will extinguish
the flames.
|
|
Execute steep 45° turn directed opposite wing
on fire
|
|
| Electrical Fire in Flight
|
| •Master: Off
|
|
Try to remove the fire's ignition source.
| | •Avionics: Off
| | •All Electrical Switches (except Magnetos): Off
| | •Cabin Heat and Vent: Close
(overhead vents Open)
| Prevent smoke and fumes from entering the cabin.
| | •Extinguish fire
| Then, ventilate the cabin with overhead vents and windows.
| Remove extinguisher products from the cabin air.
|
If fire appears out, and electrical power is necessary for continuation
of flight:
| •Radios: Off
|
|
Prepare to restart electrical equipment
one-by-one.
| | •Avionics: Off
| | •Master: On
|
|
Identify the cause of the electrical problem,
and note what equipment is inoperative.
| | •Circuit Breakers: Check but do not reset
| |
•Electrical Switches: One by one, On, delaying
between each to ensure no short circuit and fire
| | •Cabin Heat and Vent: Open
|
|
Remove remaining smoke and fumes from the cabin.
|
|
| Cabin Fire
|
| •Master: Off
|
|
Prevent secondary electrical fires?
| | •Cabin Heat and Vent: Close
(including overhead vents)
|
Prevent drafts which would provide an oxygen source
and spread flames.
|
|
| Over-voltage Light
|
| •Avionics: Off
|
|
If the source of the over-voltage has disappeared,
or the circuit triggered spuriously, try resetting
the over-voltage circuit.
Note: It appears at least some
Skyhawks actually have an under, not an
over, voltage indicator.
| | •Master: Off
| | •Master: On
| Verify over-voltage indicator remains Off.
| | •Avionics: On
|
|
| Continuous Electrical Discharge
|
| •Master Alternator: Off
|
|
Since the alternator is not providing power,
it can only represent an electrical load.
| | •Switch Off unnecessary electrical equipment
|
Minimize battery power usage.
|
|
| Static Source Blockage
|
| •Alternate Static: On
| Compensate airspeed readings in POH calibration tables
|
If the windows are closed, the calibration is
negligible.
