Brief Description: Good Engine Start and Successful Taxi Test
Fixed a new air nipple on the compressor and filled the aircraft tires to near 60 psi pressure. Prepped the engine and rolled the aircraft out of the hanger. Primed the engine for a full 5 seconds and then cranked the engine through 4 blades. Primed the engine again for 4 seconds, opened the throttle about one inch, and then closed the ignition switches and engaged the starter. The engine started immediately. Allowed the engine to run 1000rpm for a couple of minutes and then taxi down the ramp to the parking area. Made a 180 degree turn and held the brakes to bring the engine up to 2000 rpm. The brakes would not hold at that level of power. Came off the power to about a thousand rpm and taxied back to the hanger. Went through the shutdown procedures and killed the engine. Checked for leaks and loose wires around the engine. Rolled the aircraft back into the hanger and parked it in its assigned location.
Results of today’s test gave some indication as to how the engine needs to be primed for a food start. There was also a slight gas leek on the output fitting on the tank. On inspecting the brakes trying to determine why they are not more effective it was discovered that because the stator is not in the center of the caliper the brake piston is not against the pad at the start of brake application. This results in running out of brake peddle before much pressure is applied to the stator. The calipers will be remounted in the center of the stators to balance the adjustment on the pads.
Installed the AOA probe on the rheostat on the wing strut. Adjustment of the probe will be completed after the new AOA logic box is installed and working.
