## Analysis

THE ACFT WAS A REGISTERED, HOME BUILT, 2 PLACE, ULTRALIGHT VEHICLE. THE PASSENGER WAS THE PLT'S FRIEND WHO WAS BUILDING HIS OWN ULTRALIGHT & WANTED TO RIDE ALONG TO GET A GENERAL FEELING OF HOW TO LAND THIS TYPE OF ACFT. THE PLT REPORTED THAT THE TEMP WAS 86 DEG & THE WIND WAS FROM 330 DEEEG AT 8 KTS. AFTER ABOUT A 500 FT GROUND ROLL, THEY LIFTED OFF AT 30 MPH IAS. AFTER CLIMBING ABOUT 50 TO 60FT AGL, THE AIRSPEED DROPPED TO 25 MPH & THE PLT LOWERED THE NOSE TO REGAIN AIRSPEED. THE ULTRALIGHT BEGAN DESCENDING & THE PLT WAS UNABLE TO ROUND OUT BEFORE IMPACTING THE GROUND. THE ULTRALIGHT ROLLED FORWARD APRX 1 1/2 TIMES & WAS DEMOLISHED. THE DENSITY ALT WAS APRX 3100 FT.
