Maintain a level flight attitude rather than flying by reference to the altimeter and airspeed indicator as the pitot-static instruments may become very erratic.

  • Page 31 AEROBATICS (Continued) A person learning to fly must be taught how to do so safely. The san holds true for a pilot learning aerobatics. To attempt an aerobatic manuever with no prior instruction is extremely dangerous and NOT recommended. Aerobatic fl ight places a greater demand on both the pilot and aircraft. A thorough pre-flight inspection/evaluation for both is considered The pilot must know and abide by the I imitations of the essential.
  • Page 32 LANDING (Norroal) (Continued) Crosswind approaches can best be accomplished by using the wing down top rudder method followed by a wheel landing. Keep the lower wing into the wind after touchdown. Do not drop the tail until airspeed is well below flying speed. CAUTION The use of w hee l brakes 1s not recommended until after the tail wheel is in contact with the ground.

  • Page 67 GROUND HANDLING The Citabria can be easily maneuvered by one man when on firm level ground. A hand hold is provided on the right side of the fuselage forward of the tail. The tail can be lifted completely off the ground or the tail wheel steering can be disengaged with a sufficient side load for free castering.
  • Page 68 INSPECTION AND SERVICING ACCESS The Citabria is designed to keep maintenance and inspection time to a minimum. The two piece engine cowl is easily removed for engine servicing. Remove the top half first. When removing the lower half. disconnect the light wire using the quick disconnect below the inspection door on the top cowl.
  • Page 69 The system low point drain is located externall y on fuselage belly aft of the rear seat and should be used duri ng unusually gh 'moi sture conditions or if water is present in the gascolator. Each tank' ls6has a drain plug to r ffiove fuel from the tank 1f necessary. WARNING.
  • Page 71 WINDSHIELD, The windshield and side windows should be cleaned with an aircraft windshteld cleaner following the manufacturer's recollll l e ndations. dust or dirt is present, rinse with water prior to cleaning. The wind­ shield can be waxed and polished with a soft cloth to fill minor scratches and help protect against further scratchin g.
  • Page 72 To insure long engine life, the aircraft should be flown at least once a month to reduce excessive moisture buildup. Excessive ground run­ ning to bring engine to operating temperature is not recommended. Consult the engine manual for further recoHGend ations if this is not possible.
