2. Fuel Selector…………………….Off3. Master Switch……………………..Off4. Cabin Heat & Air………………….Off(Except Overhead Vents)
5. Airspeed…………………100 KIAS
(If fire is not extinguished, increase glide
speed to find an airspeed, which will
provide an incombustible mixture.)
6. Forced Ldg w/o Eng Power.ExecuteElectrical Fire in Flight
1. Master Switch .............................. Off(Leave Ignition On)
2. All Other Switches ………Off(Except Ignition)
3. Vents/Cabin Air/Heat .............Closed
4. Fire Extinguisher .................Activate

Warning
After discharging an
extinguisher within a closed
cabin, ventilate the cabin.
If fire is extinguished & electrical power
is necesary
5. Master Switch.................................On
6. Circuit Breakers................... Check for
Faulty circuit (Do Not Reset)
7. Radio/Electrical Switches on one at atime w/ delay after each to locate short.
8. Vent cabin
when assured fire isextinguishedCabin Fire
1. Master Switch .............................. Off(Leave Ignition on)
2. Vents/Cabin Air/Heat .............Closed
3. Fire Extinguisher .................Activate

Warning
After discharging an
extinguisher within a closed
cabin, ventilate the cabin.
4. Land............... As soon as possible andinspect damage
Wing Fire
1. Navigation Lights ........................ Off
2. Strobe Lights ............................... Off3. Pitot Heat ..................................... Off
4. Landing/Taxi Lights .................... Off

NoteSideslip to keep flames away from thefuel tank and cabin, and land as soon
as possible using flaps only as required
for final approach and touchdown.
Icing
1. Pitot Heat………………..…… On
2. Turn back or change altitude toobtain an outside air temp that isless conducive to icing.
3. Pull cabin heat control to full out
and open defroster outlet to obtainmaximum windshield defroster
airflow.
4. Open the throttle to increase engine
speed and minimize ice build-up on
propeller blades
5. Watch for signs of carburetor air
filter ice and apply carburetor heatas required. An unexplained loss inengine speed could be caused bycarburetor ice or air intake filter ice.
Lean the mixture if carb heat is used
continuously.
6. Plan a landing at the nearest
airport. With an extremely rapid ice
build-up, select a suitable “offairport” landing site.
7. With ice accumulation of ¼ inch or
more on the wing leading edges, beprepared for higher stall speed.
8. Leave wing flaps retracted. With asevere ice build-up on the horizontal
tail, the change in wing wake airflow
direction caused by wing flap
extension could result in a loss ofelevator effectiveness.
9. Open left window and if practicalscrape ice from a portion of thewindshield for visibility in landing
10. Perform landing approach,if necessary for improved
visibility use a forward slip
11. Approach at 80 to 90 KIAS
depending upon the amountof accumulation ice.
12. Perform a landing in level attitude.

Ditching

1. Radio………..Transmit
Maydayon 121.5 giving location andintentions and squawk 7700
2. Heavy objects………...…...Secureor Jettison
3. Flaps…………………….20º to 30º
4. Power…………….Est. a 300 FPM
descent at 55 KIAS

5. Approach …………High winds,
heavy seas Into the Wind
Light winds, heavy swells……….
Parallel to swells
Note
If no power is available, approach at70 KIAS with flaps up or at 65 KIAS
with 10º flaps.
6. Cabin Doors………………Unlatch
7. Touchdown…………Level attitudeat established descent rate
8. Face………Cushion at touchdownwith folded coat or seat cushion.
9. Airplane……….Evacuate throughCabin doors. If necessary, openwindow and flood cabin toequalize pressure so doors can be
opened.
10. Life vests and raft………..Inflate

Airspeeds for Emergency
Operations

LANDING WITHOUT ELEVATORCONTROL
Trim for horizontal flight (with an airSpeed of approximately 65 KIAS andFlaps set to 20 deg.) by using throttle
And elevator trim controls. Then DO
NOT change the elevator trim control
setting; control the glide angle byadjusting power exclusively.

Engine Failure After Takeoff:
Wing Flaps Up ------ 70KIAS
Wing Flaps Down – 65KIAS
Maneuvering Speed:
2550 Lbs –105
KIAS
2150 Lbs –- 95KIAS
1750 Lbs -- 85KIAS
Maximum Glide:2550 Lbs – 65 KIAS
2150 Lbs – 62 KIAS
1750 Lbs – 56 KIAS
Precautionary Landing WithEngine Power – 65 KIAS

At flareout, the nose-down moment
Resulting from power reduction is anAdverse factor and the airplane may hit
On the nose wheel. Consequently, atFlareout, the elevator trim control should
be adjusted toward the full noseUp position and the power adjusted sothat the airplane will rotate to the horiZontal attitude for touchdown.
Close the throttle at touchdown

This checklist is a guide to coordinate
Landing Without Engine Power:
Pilot Operating Handbook and STC data
Wing Flaps Up – 70 KIAS
applicable to this particular aircraft only.
Wing Flaps Down – 65 KIAS
The
applicable
Pilot
OperatingHandbook and STC installations remain
the official documentation for thisaircraft.
The pilot in command is responsible forcomplying with all items in the Pilot
Operating Handbook and applicable
STCs.
I certify this checklist has been reviewedfor accuracy.
