On Saturday, February 5, 2022, a Cessna 210M N732RT, s/n: 21061720, departed (mfe) mcallen international airport at approximately 12:05 pm. The aircraft had 44 gallons of fuel on board. The weather in mcallen, Laredo and on course was expected to be VFR with clear skies and calm winds. Aircraft cleared for take-off and started route direct to (lrd) Laredo International Airport, climbed to 4,500 feet and configured the aircraft to cruise settings along with the autopilot. The trip from mfe to lrd measures approximately 105 NM, at about 50 NM from lrd the autopilot disengaged. Pilot manually flew the airplane to maintain heading and altitude and was in communication with houston center on 128.15. Shortly after the autopilot disengaged the garmin avionics in the aircraft started to flicker, pilot shut off all the aircraft lighting per the checklist ?when ammeter shows discharge?. The G750 started to reset itself, all garmin avionics started flickering off and on again, the G750 reset itself five or six times before it completely shut off. The transponder went out and all the garmin avionics were out. The fuel gauges became unreliable, they started showing a significant drop in fuel. Pilot briefly considered nearest airport which was zapata county (apy), but decided to continue to final destination of lrd, because apy is an unattended airport without services and the engine was running fine. Communications with houston center were still active however not completely clear, they called to ?ident?, and pilot responded ?unable and experiencing electrical issues with the aircraft?. Houston center then asked pilot to contact them at 127.8 for further assistance, pilot responded ?unable to change frequencies with electrical issues?. They stayed with pilot on 128.15. Approximately 30 miles from lrd, communications were not going through very clearly, houston was unable to hear the pilot?s calls and the pilot could not make out their calls. Houston center picked the aircraft up again and they were able to give the pilot the current weather at lrd. Pilot declared ?airport in sight? And houston connected the aircraft to the tower via guard frequency. Laredo tower cleared aircraft to land on 36L. The aircraft was a few miles from the airport and at about 1200 ft., pilot went to extend the landing gear per the checklist and it failed. Pilot checked the circuit breakers and tried the landing gear again, nothing. Pilot then referenced the ?landing gear fails to extend? Emergency checklist in the aircraft POH. Pilot noted that the emergency hand pump required 86 cycles to manually pump the gear down. Pilot stated that ?considering the aircraft position (approaching final) and low altitude in preparation to land, the pilot didn?t think that it would be practical to completely get the gear down?. Pilot then stated that ?wanted to avoid a partial gear landing that could potentially cause more damage to the aircraft and pilot?. Pilot announced to Laredo tower that landing gear was not down and they confirmed it by sight on final approach. At this point aircraft was on short final and approximately 600 ft. from the ground approaching the runway. Pilot prepared for a gear up landing, referenced the ?gear up landing? Checklist in the POH, circuit breakers were in, adjusted airspeed to 75 KIAS, turned the fuel selector to the ?off? Position, etc. And glided the airplane down the runway in a straight line and came to a stop. No runway lights were damaged and the wings of the aircraft never touched the ground. Tower gave permission to exit the aircraft, pilot completed the shutdown checklist and exited the aircraft.
