What happened
The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.
The pilot was in level cruise at about 1500 MSL when he suffered a noticeable loss of power from his engine. He reported that he turned on carb heat and switched fuel tanks in an attempt to restore power then noticed that his oil press gauge showed his oil pressure to be well below the green band. He had just passed over anderson Island in puget sound, but could not see a clear field for an emergency landing there. He didn't want to try to make it to the mainland and wind up ditching so he opted to land on mcneil Island. He found a field that showed signs of being mowed recently and set up his pattern for an emergency landing. He landed safely with no damage to the airplane. The airplane had to be recovered from mcneil Island by removing the wings and hauling it to the owner's hangar at renton airport where it was inspected by an FAA airworthiness inspector 4 days after the incident. There was evidence of oil on the firewall and a very small amount had leaked from a fitting on the oil pressure sensing line. One of the cylinders had very low compression, but there was no clear evidence of a single cause for the loss of oil which led to the loss of power that apparently came from the engine beginning to seize up due to running with insufficient oil. There was approximately one quart of oil remaining in the crankcase when the airplane landed. The owner reported that he had topped off the oil prior to takeoff an hour prior to the loss of power and that the oil-filler cap was secure when he inspected it after landing. The owner/pilot plans to tear the engine down with and A&P mechanic to determine the damage and repair it.
As the FAA filed it
THE PILOT WAS IN LEVEL CRUISE AT ABOUT 1500 MSL WHEN HE SUFFERED A NOTICEABLE LOSS OF POWER FROM HIS ENGINE. HE REPORTED THAT HE TURNED ON CARB HEAT AND SWITCHED FUEL TANKS IN AN ATTEMPT TO RESTORE POWER THEN NOTICED THAT HIS OIL PRESS GAUGE SHOWED HIS OIL PRESSURE TO BE WELL BELOW THE GREEN BAND. HE HAD JUST PASSED OVER ANDERSON ISLAND IN PUGET SOUND, BUT COULD NOT SEE A CLEAR FIELD FOR AN EMERGENCY LANDING THERE. HE DIDN'T WANT TO TRY TO MAKE IT TO THE MAINLAND AND WIND UP DITCHING SO HE OPTED TO LAND ON MCNEIL ISLAND. HE FOUND A FIELD THAT SHOWED SIGNS OF BEING MOWED RECENTLY AND SET UP HIS PATTERN FOR AN EMERGENCY LANDING. HE LANDED SAFELY WITH NO DAMAGE TO THE AIRPLANE.THE AIRPLANE HAD TO BE RECOVERED FROM MCNEIL ISLAND BY REMOVING THE WINGS AND HAULING IT TO THE OWNER'S HANGAR AT RENTON AIRPORT WHERE IT WAS INSPECTED BY AN FAA AIRWORTHINESS INSPECTOR 4 DAYS AFTER THE INCIDENT. THERE WAS EVIDENCE OF OIL ON THE FIREWALL AND A VERY SMALL AMOUNT HAD LEAKED FROM A FITTING ON THE OIL PRESSURE SENSING LINE. ONE OF THE CYLINDERS HAD VERY LOW COMPRESSION, BUT THERE WAS NO CLEAR EVIDENCE OF A SINGLE CAUSE FOR THE LOSS OF OIL WHICH LED TO THE LOSS OF POWER THAT APPARENTLY CAME FROM THE ENGINE BEGINNING TO SEIZE UP DUE TO RUNNING WITH INSUFFICIENT OIL. THERE WAS APPROXIMATELY ONE QUART OF OIL REMAINING IN THE CRANKCASE WHEN THE AIRPLANE LANDED. THE OWNER REPORTED THAT HE HAD TOPPED OFF THE OIL PRIOR TO TAKEOFF AN HOUR PRIOR TO THE LOSS OF POWER AND THAT THE OIL-FILLER CAP WAS SECURE WHEN HE INSPECTED IT AFTER LANDING. THE OWNER/PILOT PLANS TO TEAR THE ENGINE DOWN WITH AND A&P MECHANIC TO DETERMINE THE DAMAGE AND REPAIR IT.
