Narrative:

I flew a standard pattern at standard altitude at the correct airspds as per manufacturer -- the aircraft is a small aircraft single engine land aircraft. Montauk airport is on the water with a sand dune between the beach and the runway. We were 2-3 ft AGL when windshear occurred. We were below the tree level and below the top of the sand dune. The left wing dropped without reason. It struck the ground. I tried to correct with right aileron and rudder, but nothing happened. The aileron was jammed by the strike. I landed the plane. As we were rolling out, I had no control of the nosewheel. I tried to brake but as we slowed, the aircraft turned sharply to the right, went off the runway into a ditch. No one was hurt (I used left rudder to correct, but nothing happened) -- cause was clearly windshear that caused the wing to drop. This airport is right on the water. There were not any NOTAMS for windshear -- this airport needs more wind socks and windshear detection device. Upon reading FAA and NTSB reporting guidelines, this appeared to be an incident which did not require notifying either the FAA or NTSB. My lawyer agreed it did not require notification to either FAA or NTSB.

Title: PRIVATE PLT OF SMA ACFT LOST CTL OF THE ACFT DURING LNDG RESULTING IN MINOR DAMAGE TO THE ACFT.

Narrative: I FLEW A STANDARD PATTERN AT STANDARD ALT AT THE CORRECT AIRSPDS AS PER MANUFACTURER -- THE ACFT IS A SMA SINGLE ENG LAND ACFT. MONTAUK ARPT IS ON THE WATER WITH A SAND DUNE BTWN THE BEACH AND THE RWY. WE WERE 2-3 FT AGL WHEN WINDSHEAR OCCURRED. WE WERE BELOW THE TREE LEVEL AND BELOW THE TOP OF THE SAND DUNE. THE L WING DROPPED WITHOUT REASON. IT STRUCK THE GND. I TRIED TO CORRECT WITH R AILERON AND RUDDER, BUT NOTHING HAPPENED. THE AILERON WAS JAMMED BY THE STRIKE. I LANDED THE PLANE. AS WE WERE ROLLING OUT, I HAD NO CTL OF THE NOSEWHEEL. I TRIED TO BRAKE BUT AS WE SLOWED, THE ACFT TURNED SHARPLY TO THE R, WENT OFF THE RWY INTO A DITCH. NO ONE WAS HURT (I USED L RUDDER TO CORRECT, BUT NOTHING HAPPENED) -- CAUSE WAS CLRLY WINDSHEAR THAT CAUSED THE WING TO DROP. THIS ARPT IS RIGHT ON THE WATER. THERE WERE NOT ANY NOTAMS FOR WINDSHEAR -- THIS ARPT NEEDS MORE WIND SOCKS AND WINDSHEAR DETECTION DEVICE. UPON READING FAA AND NTSB RPTING GUIDELINES, THIS APPEARED TO BE AN INCIDENT WHICH DID NOT REQUIRE NOTIFYING EITHER THE FAA OR NTSB. MY LAWYER AGREED IT DID NOT REQUIRE NOTIFICATION TO EITHER FAA OR NTSB.
