What happened
The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.
The pilot stated on the morning of July 30, 2023, he and his privacy data omitteddeparted 66S (cavenaugh bay) at 0803 enroute mostly direct to S36 (norman grier). The pilot climbed to an altitude of 8800FT MSL then decided to come down lower for lesser headwinds. The sky was clear above 10,000 ft and the winds seemed to be out of the west between 15 to 20 KTS. The pilot was showing 2 hrs enroute with an ETA to S36 at around 1000 hours. Each of aircraft's fuel tanks were reading over 25 gallons but slightly less than 30 gallon for a total of 57-60 gallons. The pilot cruise settings for the aircraft is 24"mp and 1950RPM. When the pilot leaned out the engine burns close to 18GAL/HR. Not leaned the engine the engine would burns 20-21 gal/hr. Pilot leaned the engine for 1.75 hrs of his flight.
After the first hour pilot noticed the right tank was burning faster the left tank, 17-18 left side and 10-12 on the right. His privacy data omittedcommented on the fact that she could smell raw fuel. Pilot thought maybe she was imagining it. The pilot stated he could just maybe smell a hint of fuel. The pilot decided to switch the fuel selector from "both" to "left." The pilot stated he have not seen this before with other flights. After he felt, the left tank had burned to where the right level was at, 12 left and 12 right, the pilot switched the fuel selector back to "both" he calculated in his head approximately one hour, 20 minutes of fuel left and 45 minutes to his destination. At 0948 hrs, pilot turned to fly the stampede pass route while at 4400FT, 15 minutes from his destination. The right tank reading 5 gallons and the left tank reading 7-10. As the pilot started to descend the stampede pass valley pilot flew another 10 minutes and the engine started to sputter and loose power. Pilot switched tanks to "left" then the engine started up again briefly for a minute or so, then the engine went to idle. Pilot switched the tank back to "both." At this point, 0956HRS pilot told his privacy data omitted we were going down. Aircraft were at 3000FT. The only thing remotely the pilot felt he could make it to was a small unknown clearing he spotted off in the FAR distant.
At 1001 hours, the pilot was able to just make the clearing which turned out to be a grassy gravel fenced in parking lot. Pilot landed both wheels, and applied brakes immediatley. I first collided into a 3 foot metal post. The planed slowed briefly then the right-wing tip collided into a 15'X15'X 7' high enclosed room which caused it to now skid on its left wheel. The left main landing gear buckled and the plane tipped onto its left-wing tip coming to a stop. The pilot yelled to his privacy data omitted to get out but she replied for me to turn the engine off first. I had not noticed but the engine was still running at an idle, 600RPM. The pilot turned the ignition switch off, the master switch off, then I exited the plane. Both the pilot and privacy data omitted were not injured.
This maybe amended at a later date when NTSB submitt the final report
As the FAA filed it
THE PILOT STATED ON THE MORNING OF JULY 30, 2023, HE AND HIS ^PRIVACY DATA OMITTED^DEPARTED 66S (CAVENAUGH BAY) AT 0803 ENROUTE MOSTLY DIRECT TO S36 (NORMAN GRIER). THE PILOT CLIMBED TO AN ALTITUDE OF 8800FT MSL THEN DECIDED TO COME DOWN LOWER FOR LESSER HEADWINDS. THE SKY WAS CLEAR ABOVE 10,000 FT AND THE WINDS SEEMED TO BE OUT OF THE WEST BETWEEN 15 TO 20 KTS. THE PILOT WAS SHOWING 2 HRS ENROUTE WITH AN ETA TO S36 AT AROUND 1000 HOURS. EACH OF AIRCRAFT'S FUEL TANKS WERE READING OVER 25 GALLONS BUT SLIGHTLY LESS THAN 30 GALLON FOR A TOTAL OF 57-60 GALLONS. THE PILOT CRUISE SETTINGS FOR THE AIRCRAFT IS 24"MP AND 1950RPM. WHEN THE PILOT LEANED OUT THE ENGINE BURNS CLOSE TO 18GAL/HR. NOT LEANED THE ENGINE THE ENGINE WOULD BURNS 20-21 GAL/HR. PILOT LEANED THE ENGINE FOR 1.75 HRS OF HIS FLIGHT.
AFTER THE FIRST HOUR PILOT NOTICED THE RIGHT TANK WAS BURNING FASTER THE LEFT TANK, 17-18 LEFT SIDE AND 10-12 ON THE RIGHT. HIS ^PRIVACY DATA OMITTED^COMMENTED ON THE FACT THAT SHE COULD SMELL RAW FUEL. PILOT THOUGHT MAYBE SHE WAS IMAGINING IT. THE PILOT STATED HE COULD JUST MAYBE SMELL A HINT OF FUEL. THE PILOT DECIDED TO SWITCH THE FUEL SELECTOR FROM "BOTH" TO "LEFT." THE PILOT STATED HE HAVE NOT SEEN THIS BEFORE WITH OTHER FLIGHTS. AFTER HE FELT, THE LEFT TANK HAD BURNED TO WHERE THE RIGHT LEVEL WAS AT, 12 LEFT AND 12 RIGHT, THE PILOT SWITCHED THE FUEL SELECTOR BACK TO "BOTH" HE CALCULATED IN HIS HEAD APPROXIMATELY ONE HOUR, 20 MINUTES OF FUEL LEFT AND 45 MINUTES TO HIS DESTINATION. AT 0948 HRS, PILOT TURNED TO FLY THE STAMPEDE PASS ROUTE WHILE AT 4400FT, 15 MINUTES FROM HIS DESTINATION. THE RIGHT TANK READING 5 GALLONS AND THE LEFT TANK READING 7-10. AS THE PILOT STARTED TO DESCEND THE STAMPEDE PASS VALLEY PILOT FLEW ANOTHER 10 MINUTES AND THE ENGINE STARTED TO SPUTTER AND LOOSE POWER. PILOT SWITCHED TANKS TO "LEFT" THEN THE ENGINE STARTED UP AGAIN BRIEFLY FOR A MINUTE OR SO, THEN THE ENGINE WENT TO IDLE. PILOT SWITCHED THE TANK BACK TO "BOTH." AT THIS POINT, 0956HRS PILOT TOLD HIS ^PRIVACY DATA OMITTED^ WE WERE GOING DOWN. AIRCRAFT WERE AT 3000FT. THE ONLY THING REMOTELY THE PILOT FELT HE COULD MAKE IT TO WAS A SMALL UNKNOWN CLEARING HE SPOTTED OFF IN THE FAR DISTANT.
AT 1001 HOURS, THE PILOT WAS ABLE TO JUST MAKE THE CLEARING WHICH TURNED OUT TO BE A GRASSY GRAVEL FENCED IN PARKING LOT. PILOT LANDED BOTH WHEELS, AND APPLIED BRAKES IMMEDIATLEY. I FIRST COLLIDED INTO A 3 FOOT METAL POST. THE PLANED SLOWED BRIEFLY THEN THE RIGHT-WING TIP COLLIDED INTO A 15'X15'X 7' HIGH ENCLOSED ROOM WHICH CAUSED IT TO NOW SKID ON ITS LEFT WHEEL. THE LEFT MAIN LANDING GEAR BUCKLED AND THE PLANE TIPPED ONTO ITS LEFT-WING TIP COMING TO A STOP. THE PILOT YELLED TO HIS ^PRIVACY DATA OMITTED^ TO GET OUT BUT SHE REPLIED FOR ME TO TURN THE ENGINE OFF FIRST. I HAD NOT NOTICED BUT THE ENGINE WAS STILL RUNNING AT AN IDLE, 600RPM. THE PILOT TURNED THE IGNITION SWITCH OFF, THE MASTER SWITCH OFF, THEN I EXITED THE PLANE. BOTH THE PILOT AND ^PRIVACY DATA OMITTED^ WERE NOT INJURED.
THIS MAYBE AMENDED AT A LATER DATE WHEN NTSB SUBMITT THE FINAL REPORT
