Page 5: Design Information
Section II – DESIGN INFORMATION ENGINE AND PROPELLER The Grizzly Cub is powered by a Lycoming 0-320 engine, with a rated horsepower of 160 at 2700 RPM. The standard installation of this engine includes an electrical system. On the 160 hp engine, the standard propeller is the Sensenich metal design 74-DM-56. In general, propeller designs selected for the Grizzly Cub emphasize takeoff, climb and economical cruising performance rather than high speed cruising.
Page 6 Landing Gear Shock Struts. CONTROL SYSTEMS The units which make up the empennage are the fin, rudder, stabilizers and elevators. They are all constructed of tubular steel with steel channel ribs. The control surface hinges have bronze bushing inserts which should be oiled occasionally with light oil.
Page 7 The fuel strainer, on the lower left side of the fire wall in the engine compartment is installed to trap water or sediment that may collect in the fuel system. It should be drained before each flight. Fuel screens are provided at each tank outlet, in the strainer, and at the carburetor.
Page 8 An integral overvoltage relay protects the electrical system from an overvoltage condition. FINISH The finish is PolyUrethane Lockhaven Yellow paint over top of fire resistant butyrate plastic material on the fabric surfaces. All of the covering material, inside and outside, on the Grizzly Cub is treated with butyrate plastic over 5 primer coats of nitrate dope.

SECTION III OPERATING INSTRUCTIONS PREFLIGHT The following safety procedure instructions must become an integral part of the aircraft owner's operational routine and preflight inspection. Before each flight visually inspect the airplane and determine that: Ignition and battery switches "OFF." b. Mixture to idle cut-off a.
Page 10 STARTING When the engine is cold, prime three to five strokes after turning fuel valve to the on position. Push mixture control to full rich, carburetor heat off, and open throttle about one-eighth of an inch or until the intake of air at the carburetor can be heard when the engine is pulled through by hand.
Page 11 climbing airspeed has been reached to achieve maximum rate of climb. The best rate of climb airspeed at gross load is 55 MPH. At lighter weights, the best climbing airspeed will be reduced proportionally. The gross weight power off stalling speed with full flaps in the Grizzly Cub 150 is 28 MPH IAS; with flaps up the stalling speed increases about 3 MPH.
Page 12 Before shutting down the engine, set throttle to idle and turn the magneto switches off momentarily to check magneto grounding. To stop the engine, after landing and when clear of the runway, pull the mixture control full out to idle cui-off. When using alternate fuels, the engine should be run up to 1200 RPM for one minute prior to shutdown to clean out any unburned fuel.

Page 14: Emergency Procedures
EMERGENCY LOCATOR TRANSMITTER The Emergency Locator Transmitter (ELT), when installed, is located in the fuselage just aft of the battery and is accessible through a removable plate on the upper right side of the fuselage. The ELT meets the requirements of FAR 91.52.
Page 15 Most basic emergency procedures, such as power off landings, are a normal part of pilot training. Although these emergencies are discussed herein, this information is not intended to replace such training, but only to provide a source of reference and review, and to provide information on procedures which are not the same for all aircraft. It is suggested that the pilots review standard emergency procedures periodically to remain proficient in them.
Page 16 PARTIAL POWER LOSS If the engine is producing partial power and time permits: Ignition Switch - "L" then R" then back to "BOTH." Throttle and Mixture - Different settings. (This may restore power if problem is too rich or too lean a mixture, or a partial fuel system restriction.) NOTE If engine failure was caused by fuel exhaustion, power will not be regained .
Page 17 The possibility of an engine fire in flight is extremely remote. The procedure given above is general and pilot judgment should be the deciding factor for action in such an emergency. Engine Fire During Start: If engine has not started Mixture - Idle Cut-Off Throttle - Open Turn engine with starter (This is an attempt to pull the fire into the engine.)
Page 18 ALTERNATOR FAILURE Loss of alternator output is detected through a zero reading on the ammeter. Before executing the following procedure, insure that the reading is zero and not merely low by actuating an electrically powered device, such as the landing light. If no increase in the ammeter reading is noted, alternator failure can be assumed. Reduce Electrical Load.

Page 20: General Maintenance
SECTION VI SECTION VI GENERAL MAINTENANCE ENGINE ACCESS The steel tubular engine mount on the Grizzly Cub is mounted to the fuselage at the firewall on hinges, so that the rear of the engine can readily be made accessible for service. To hinge the motor mount, first remove the top, side and bottom engine cowl panels which are quickly detachable by means of cowl fasteners.
Page 21 The oil capacity of the O-320 series engine is 8 quarts, and the minimum safe quantity is 2 quarts. It is recommended that the oil be changed every 50 hours and sooner under unfavorable operating conditions. Intervals between oil changes can be increased as much as 100% on engines equipped with full flow cartridge type oil filters, provided the element is replaced each 50 hours of operation and the specified octane fuel is used.
Page 22 If the present element is found to be in good condition and is not obstructed after being properly cleaned (see paragraphs 1 and 2), the following check should be made: Operate engine to static RPM at full throttle and note RPM. Remove filter cartridge and repeat operation in paragraph 3a.

Page 24 perpendicular to the straight edge will cause a deflection of 7/16 ± 1/16 inches on a tail wire under proper tension. Adjust all wires to this tension. CONTROL SURFACE RIGGING Elevator cable tension should be checked and set to a tension of 62 t 2 pounds. (See Tail Surface Control System, page 22.) Aileron cable tension should be checked and set to a tension of 40 ±...
