Maintenance History

At forward end of right wing Crack appearing in clear light cover.from forward most Phillips head screw.

Stop drilled cracks in right hand wing outboard lens cover.

Seat stop for co-pilots chair is broken off on one side. Aircraft determined to be unsafe for flight until repaired. Parts are on order..

Repaired by Merritt Island Aviation. See logbook entry dated 08-21-2026 for details of work performed.

LH Flap top inboard skin has a been rubbing and worn.

The area of rub was resolved during a previous maintenance event. Applied protective coating to bare aluminum surface that was exposed and maintenance will continue to monitor for any future re-occurrence of the rub.

Center Landing light is only attached to one side of the mounting bracket

Re-attached nose light mounting bracket to assembly. Function & Ops check good.

Today’s flight I was practicing commercial takeoff and landings. I did 7 TO/LDG’s. Upon arrival to the hanger I noticed the right tire was flat. I did not notice any problems on any of the takeoffs and taxi back to the hanger. I filled up the tire and noticed that air was leaking out of the value stem, I could not hear any air leaking out of the tire itself.

Removed and reinstalled right wheel. Cleaned & inspected wheel halves. Installed new tube PN: GL-6020B. Flipped and reinstalled original 6.00-6 tire, SN: 8AB3E41025. All work done in accordance with Cessna 172 Service Manual. Functional and leak check satisfactory.

Flap overspeed

Inspected flap system due to reported overspeed (flaps 10° at ~95 KIAS for approx. 2 minutes). Inspected flap hinges, tracks, rollers, actuator, and associated wing structure. No defects or abnormalities noted. Flap system function checked satisfactory. Aircraft returned to service.

Left wing strut upper fairing has screw stuck under plastic.

Removed FOD from LH strut upper fairing

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
