Narrative:

Departed sbound from stanley airport at approximately XA30 pm jul/sun/95. Temperature 60 degrees. Became airborne approximately 1000 ft from the end. Began raising flaps at departure and when we felt a downdraft, I left the flaps alone. We immediately encountered another stronger downdraft. Unable to maintain altitude with full power and flaps. Was forced to try to execute landing in the field about 1000 ft to 1500 ft from the runway. Nosewheel hit a hole and the plane flipped. No one was hurt.

Title: DOWNDRAFTS AT A HIGH ALT ARPT CAUSE AN OFF ARPT LNDG.

Narrative: DEPARTED SBOUND FROM STANLEY ARPT AT APPROX XA30 PM JUL/SUN/95. TEMP 60 DEGS. BECAME AIRBORNE APPROX 1000 FT FROM THE END. BEGAN RAISING FLAPS AT DEP AND WHEN WE FELT A DOWNDRAFT, I LEFT THE FLAPS ALONE. WE IMMEDIATELY ENCOUNTERED ANOTHER STRONGER DOWNDRAFT. UNABLE TO MAINTAIN ALT WITH FULL PWR AND FLAPS. WAS FORCED TO TRY TO EXECUTE LNDG IN THE FIELD ABOUT 1000 FT TO 1500 FT FROM THE RWY. NOSEWHEEL HIT A HOLE AND THE PLANE FLIPPED. NO ONE WAS HURT.
