Narrative:

Non rated friend bought an aircraft and asked if I would take him flying. I have heavy jet time and am relatively inexperienced with light civil aircraft. Having already flown that morning, I called my friend and expressed reservations about flying with such strong winds, 330/16g24. The winds at the field didn't seem too bad, so the decision to go was made. A normal preflight, start, taxi and takeoff was made, with the intention of performing a local fam flight. Several turns, stalls and approach turn stalls were performed, and a return to the field for landing practice. 3 approachs were made, and on the fourth, at approximately 50' AGL and 85-90 mph, low level wind shear was encountered and the nose of the aircraft dropped rapidly. Full power was added with nose up pressure. This was insufficient to keep the nose wheel from impacting the runway. The nose gear broke and the aircraft departed the left side, coming to rest in approximately 1000'. I must say the wind shear actually caused this incident. Whether wind shear causing stall or downdraft I'll never know. The primary contributing factor has to be a poor decision to go flying in what turned out to be unfavorable conditions with operators inexperienced in that particular aircraft type.

Narrative: NON RATED FRIEND BOUGHT AN ACFT AND ASKED IF I WOULD TAKE HIM FLYING. I HAVE HVY JET TIME AND AM RELATIVELY INEXPERIENCED WITH LIGHT CIVIL ACFT. HAVING ALREADY FLOWN THAT MORNING, I CALLED MY FRIEND AND EXPRESSED RESERVATIONS ABOUT FLYING WITH SUCH STRONG WINDS, 330/16G24. THE WINDS AT THE FIELD DIDN'T SEEM TOO BAD, SO THE DECISION TO GO WAS MADE. A NORMAL PREFLT, START, TAXI AND TKOF WAS MADE, WITH THE INTENTION OF PERFORMING A LCL FAM FLT. SEVERAL TURNS, STALLS AND APCH TURN STALLS WERE PERFORMED, AND A RETURN TO THE FIELD FOR LNDG PRACTICE. 3 APCHS WERE MADE, AND ON THE FOURTH, AT APPROX 50' AGL AND 85-90 MPH, LOW LEVEL WIND SHEAR WAS ENCOUNTERED AND THE NOSE OF THE ACFT DROPPED RAPIDLY. FULL PWR WAS ADDED WITH NOSE UP PRESSURE. THIS WAS INSUFFICIENT TO KEEP THE NOSE WHEEL FROM IMPACTING THE RWY. THE NOSE GEAR BROKE AND THE ACFT DEPARTED THE LEFT SIDE, COMING TO REST IN APPROX 1000'. I MUST SAY THE WIND SHEAR ACTUALLY CAUSED THIS INCIDENT. WHETHER WIND SHEAR CAUSING STALL OR DOWNDRAFT I'LL NEVER KNOW. THE PRIMARY CONTRIBUTING FACTOR HAS TO BE A POOR DECISION TO GO FLYING IN WHAT TURNED OUT TO BE UNFAVORABLE CONDITIONS WITH OPERATORS INEXPERIENCED IN THAT PARTICULAR ACFT TYPE.
