LIMITATIONS MODEL 150M
MANEUVER LIMITS
This airplane is certificated in the utility category and is designed
for limited aerobatic flight. In the acquisition of various certificates
such as commercial pilot, instrument pilot and flight instructor, certain
maneuvers are required. All of these maneuvers are permitted in this
airplane.
No aerobatic maneuvers are approved except those listed below:
MANEUVER MAXIMUM ENTRY SPEED*
Chandelles 95 knots
Lazy Eights 95 knots
Steep Turns 95 knots
Spins Use Slow Deceleration
Stalls (Except Whip Stalls) Use Slow Deceleration
* Higher speeds can be used if abrupt use of the controls is avoided.
Aerobatics that may impose high loads should not be attempted. The
important thing to bear in mind in flight maneuvers is that the airplane is
clean in aerodynamic design and will build up speed quickly withthe nose
down. Proper speed control is an essential requirement for execution of
any maneuver, and care should always be exercised to avoid excessive
speed which in turn can impose excessive loads. In the execution of all
maneuvers, avoid abrupt use of controls.
FLIGHT LOAD FACTOR LIMITS
Flight Load Factors:
*Flaps Up: +4.4g , -1.76g
*Flaps Down: +3. 5g
*The design load factors are 150% of the above, and in ail cases,

INTRODUCTION
Section 3 provides checklist and amplified procedures for coping with
emergencies that may occur. Emergencies caused by airplane or engine
malfunctions are extremely rare if proper preflight inspections and main-
tenance are practiced. Enroute weather emergencies can be minimized
or eliminated by careful flight planning and good judgement when unexpect-
ed weather is encountered. However, should an emergency arise, the
basic guidelines described in this section should be considered and applied
as necessary to correct the problem. Emergency procedures associated
with the ELT and other optional systems can be found in Section 9.

FIRES
DURING START ON GROUND
(1) Cranking — CONTINUE, to get a start which would suck the
flames and accumulated fuel through the carburetor and into the
engine.
If engine starts:
(2) Power — 1700 RPM for a few minutes.
(3) Engine - SHUTDOWN and inspect for damage.
If engine fails to start:
(4) Cranking — CONTINUE in an effort to obtain a start.
(5) Fire Extinguisher — OBTAIN (have ground attendants obtain if
not installed).
(6) Engine — SECURE.

(1) Master Switch — OFF.
(2) All Other Switches (except ignition switch) — OFF.
(3) Vents/Cabin Air/Heat - CLOSED.
(4) Fire Extinguisher — ACTIVATE (if available).
After discharging an extinguisher within a closed cabin,
ventilate the cabin.
If fire appears out and electrical power is necessary for continuance
of flight:
(5) Master Switch- ON.
(6) Circuit Breakers — -CHECK for faulty circuit, do not reset.
(7) Radio/Electrical Switches — ON one at a time, with delay after
each until short circuit is localized.
(8) Vents/Cabin Air/Heat — OPEN when it is ascertained that fire
is completely extinguished.
CABIN FIRE
(1) Master Switch -- OFF.
(2) Vents/Cabin Air/Heat — CLOSED (to avoid drafts).
(3) Fire Extinguisher — ACTIVATE (if available).
After discharging an extinguisher within a closed cabin,
ventilate the cabin.

WING FIRE
(1) Navigation Light Switch -- OFF.
(2) Strobe Light Switch -- OFF.
(3) Pitot Heat Switch -- OFF.
NOTE
Perform a side slip to keep the flames away from the
fuel tank and cabin, and land as soon as possible, with
flaps retracted.
ICING
INADVERTENT ICING ENCOUNTER
(1) Turn pitot heat switch ON (if installed).
(2) Turn back or change altitude to obtain an outside air
temperature that is less conducive to icing.
(3) Pull cabin heat control full out to obtain maximum defroster air
temperature. For greater air flow at reduced temperatures, adjust
the cabin air control as required.
(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
heat as required. An unexpected loss in engine speed could be
caused by carburetor ice or air intake filter ice. Lean the mixture
for maximum RPM, if carburetor heat is used continuously.
(6) Plan a landing at the nearest airport. With an extremely rapid
ice build-up, select a suitable "off airport" landing site.
(7) With an ice accumulation of 1/4 inch or more on the wing
leading edges, be prepared for significantly higher stall speed.
(8) Leave wing flaps retracted. With a severe ice build-up on the
horizontal tail, the change in wing wake airflow direction caused
by wing flap extension could result in a loss of elevator effectiveness.
(9) Open left window and if practical scrape ice from a portion of
the windshield for visibility in the landing approach.
(10) Perform a landing approach using a forward slip, if
necessary, for improved visibility.
(11) Approach at 65 to 75 KIAS depending upon the
amount of ice accumulation.
(12) Perform a landing in level attitude.
