Narrative:

I was attempting to make a short 30 mi flight to return to my home base ZZZ. There was a line of thunderstorms moving towards us from the west. My route of flight was due south. After takeoff and flying south for 5 mins, it became apparent that we would not be able to continue to ZZZ because rain showers had moved into that area. I turned around headed back to M01. The winds had been out of the south all day, so I re-entered the downwind for runway 16. The winds were beginning to get gusty from the approaching thunderstorm. On final approach, the winds were requiring considerable right crab indicating stronger winds from the west. I landed 1000 ft from the approach end of runway 16, which is 3800 ft long. Just as I touched down, we were hit from the rear by a very strong gust front of the approaching thunderstorm. The microburst and resulting windshear were recorded at 50 mph. With the strong tailwind on the runway, I was unable to stop the aircraft and feared doing a go around in a potentially unsurvivable windshear condition. We impacted the fence off the end of the runway. There were no injuries, the aircraft sustained minor damage. I should have delayed the flight until the thunderstorms had moved through the area. On my return to M01, I should have considered the possibility of windshear and diverted to a field which was further away from the approaching storm. Callback conversation with reporter revealed the following information: reporter stated that the aircraft was a low wing radial engined retractable gear foreign military trainer certificated in the experimental category. The nose gear and propeller were damaged when the aircraft exited the runway into a ditch and hit a fence.

Title: PLT OF A NANCHANG CJ6A MIL TRAINER LOST CTL DURING GUSTY WINDSHEAR CONDITIONS DURING LNDG AT AN UNCTLED ARPT RESULTING IN RUNNING OFF THE RWY INTO A DITCH AND HITTING A FENCE. THE ACFT'S NOSE GEAR WAS COLLAPSED AND THE PROP BLADES BENT. THERE WERE NO INJURIES TO THE 2 OCCUPANTS.

Narrative: I WAS ATTEMPTING TO MAKE A SHORT 30 MI FLT TO RETURN TO MY HOME BASE ZZZ. THERE WAS A LINE OF TSTMS MOVING TOWARDS US FROM THE W. MY RTE OF FLT WAS DUE S. AFTER TKOF AND FLYING S FOR 5 MINS, IT BECAME APPARENT THAT WE WOULD NOT BE ABLE TO CONTINUE TO ZZZ BECAUSE RAIN SHOWERS HAD MOVED INTO THAT AREA. I TURNED AROUND HEADED BACK TO M01. THE WINDS HAD BEEN OUT OF THE S ALL DAY, SO I RE-ENTERED THE DOWNWIND FOR RWY 16. THE WINDS WERE BEGINNING TO GET GUSTY FROM THE APCHING TSTM. ON FINAL APCH, THE WINDS WERE REQUIRING CONSIDERABLE R CRAB INDICATING STRONGER WINDS FROM THE W. I LANDED 1000 FT FROM THE APCH END OF RWY 16, WHICH IS 3800 FT LONG. JUST AS I TOUCHED DOWN, WE WERE HIT FROM THE REAR BY A VERY STRONG GUST FRONT OF THE APCHING TSTM. THE MICROBURST AND RESULTING WINDSHEAR WERE RECORDED AT 50 MPH. WITH THE STRONG TAILWIND ON THE RWY, I WAS UNABLE TO STOP THE ACFT AND FEARED DOING A GAR IN A POTENTIALLY UNSURVIVABLE WINDSHEAR CONDITION. WE IMPACTED THE FENCE OFF THE END OF THE RWY. THERE WERE NO INJURIES, THE ACFT SUSTAINED MINOR DAMAGE. I SHOULD HAVE DELAYED THE FLT UNTIL THE TSTMS HAD MOVED THROUGH THE AREA. ON MY RETURN TO M01, I SHOULD HAVE CONSIDERED THE POSSIBILITY OF WINDSHEAR AND DIVERTED TO A FIELD WHICH WAS FURTHER AWAY FROM THE APCHING STORM. CALLBACK CONVERSATION WITH RPTR REVEALED THE FOLLOWING INFO: RPTR STATED THAT THE ACFT WAS A LOW WING RADIAL ENGINED RETRACTABLE GEAR FOREIGN MIL TRAINER CERTIFICATED IN THE EXPERIMENTAL CATEGORY. THE NOSE GEAR AND PROP WERE DAMAGED WHEN THE ACFT EXITED THE RWY INTO A DITCH AND HIT A FENCE.
