Nav light switch does not “Click” AND NAV lights do not turn. Plane is “Day Only”

Found nav light circuit breaker out. Reset breaker and tested nav lights for several minutes. Function test good at this time. Let maintenance know if the issue comes back in the future and we will try to source a new switch.

-Found landing light switch stuck in the “On” position. Removed switch to obtain part number.

-Aircraft is available for day flight only since landing lights have been disabled awaiting parts.

-Removed defective switch and replaced with new. Functional check satisfactory.

-Electric voltage and amperage on the CGR-30 showed cycling during flight. It would show 14v and a charging current of mid teens they would then degrade to a negative amperage and voltage would start to drop. If you cycle the left half of the Master Switch to cycle the alternator the current becomes positive for a few seconds the voltage immediately goes to 13.9 then the current and battery voltage starts to reduce until a negative charging current persists. It seems like the Alternator is only charging based on some voltage setpoint. If above the setpoint the alternator reduces its output and allows the battery to provide the current demand. When below the setpoint the alternator produces a charging current to increase battery voltage.

-Replaced voltage regulator. Functional check satisfactory. Appropriate entry entered in aircraft logs this date for return to service. djv

#1Cyl CHT reads 100 degrees less than #2 Cyl. Appears to be cowling ambient Temp.

Repaired defective electrical connection at OLC connector. Check next flight.

-While taxing at night pilot hit the leading edge of the right wing on a dark flag pole. Photos were sent to Jay Gebhard.

– Removed damaged Right outboard Stene Aviation Sportsman STOL Leading edge. Found no damage to original aircraft structure or wing. Replaced Stene right outboard leading with new components from Stene Aviation. Flight check satisfactory. See appropriate log book entry.

– Fuel flow reads too high. 98 GPH +.”OVA”

– Repaired open at fuel flow electrical connector. Functional check satisfactory. See appropriate log book entry.

-Left fuel tank sump drips fuel.

-Replaced fuel drain with new p/n 05-01877. Functional check satisfactory.

-Oil is leaking from the motor.

-Found #1 Exhaust & #3 Intake push rod tubes leaking. Disassembled and reassembled with new pushrod tube seals. Functional and leak checks satisfactory.

– Engine oil leaking from left side.

– See appropriate engine log book entry this date. Leak repaired, tested and found satisfactory.
