Notes, Cautions, and Warnings

WARNING – This aircraft uses an electrically-dependent igntion system. With any electrical failure, reduce electrical load and land as soon as possible.

WARNING: Takeoff and land with both boost pumps on. After takeoff, either boost pump may be turned off.

WARNING: Brake lines are to be replaced every 5 years at the Condition Inspection. Brake fluid (5606) is to be replaced no less frequently. Brake fluid absorbs moisture which lowers the boiling point of the fluid and contributes to caliper corrosion. Bottom-filling of brake lines is recommended. Suction old fluid out of the reservoirs with a large syringe and place the extended nose gear on an elevated platform. Pump new fluid in at the brake caliper until fluid appears clean and free of bubbles.

CAUTION – If the nose inadventently rises more than a few inches, a tipback can happen quickly which will damage wheel pants and prop. When parked on three wheels with the cockpit empty: i) insure the 25 lb weight is hung in the nose gear; ii) lower the nosewheel if parked pointed into a strong wind or on an upslope. Apply the parking brake when parked on a downslope.

CAUTION: The nose gear mechanism must be fully extended over-center or fully retracted. If weight is placed on the nose in any other position, it may strip the gear in the mechanism. A stripped gear can be reversed for one more usage.

CAUTION: For safe stall behavior, this aircraft requires 16# of ballast placed ahead of the rudder pedals with a 225 pilot. Cast lead weights fit in the compartments under the nose hatch.

CAUTION: To prevent nose gear damage, avoid taxiing into potholes or ground-wire depressions on the ramp.

CAUTION: Keep the swiveling nose gear adjusted so that that a hard blow with the fist against the tire does not freely deflect the tire, otherwise, the nose gear may shimmy and destroy the nose gear.

CAUTION: There is no warning of an unlocked canopy in this aircraft. Insure that the canopy emergency catch is bent so that it engages when the canopy is lifted.

CAUTION: Leaning during ground operations is recommended, however, lean so that if the throttle is inadvertently advanced for takeoff with the engine leaned, the engine will die.

CAUTION: In the event of alternator failure, lowest current drain will be achieved by selecting E-bus power, then turn off the master switch, then selectively turn off any E-bus-powered equipment that is not needed (i.e., com radio, transponder, D-10A, one fuel pump). Turn off Lightspeed Ignition #2 to save the backup battery for last use.

NOTE: Before removing fuel tank caps for refueling, attach the fueling ground wire to the step. The step is bonded to each fuel cap ring via internal wiring.

NOTE:: For normal operation, maintain Ignition 2 Pwr Select in the “aux batt” position. This checks the condition of the aux battery.

NOTE: Lightspeed ignition #1 is powered directly from the main battery and #2 is normally powered from the aux battery, each through its own switch. If alternator failure occurs, reduce any other electrical load and turn off one igntion (normally turn off #2) until the main battery is exhausted, then turn on ignition #2

NOTE: Spare fuses are stored in a red bag in the right strake hole.

NOTE: If the fuel valve binds, position the aircraft nose-high, disassemble and lube the spool with a tiny smear of Fuel Lube. If too much Fuel Lube is used, bits of it can lodge in the gascolator screen (where it will not desolve!).

NOTE: Tire pressures are 50# main wheels, 65# nose gear. It is particularly important to keep the nose tire inflated to avoid turning on the rim at touchdown.

NOTE: This aircraft uses DOT3/4 brake fluid and EPDM o-rings in brake hardware.

NOTE: The Dynon D-10A EFIS and uMonitor are powered via the E-bus and will indicate approximately one volt less than battery voltage due to loss in the E-bus diode.

NOTE: Water is seldom found in the tank or gascolator drains but if any water is found in the tank drains, then also check the gascolator for water.

NOTE: At high cruise speed and wide-open-throttle, the throttle may need to be retarded slightly for smooth running and peak RPM.

NOTE: This Ellison carburetor set-up exhibits a slight engine surge at medium RPM.

NOTE: For instrument access: remove the canard cover, remove two long pins securing the instrument cover, remove instrument cover and disconnect the connector for cockpit lights.

NOTE: To remove the canard, remove the instrument cover as described above, remove the footwell access hatch, disconnect the elevator control rod quick-disconnect (starboard side), loosen two screws holding the trim spring wires in the trim mechanism (port side), disconnect Dynon remote compass box, unscrew & remove two screws through the canard incidence-setting tabs, unbolt the canard lift tabs, lift the canard up and out.
