## Analysis

DURING A LOCAL FLT, THE ACFT CRASHED ON THE SIDE OF A LEVEE WHILE MANEUVERING. BOTH PLTS WERE SERIOUSLY INJURED & NEITHER OF THEM COULD RECALL DETAILS OF THE FLT. AN EXAM OF THE CRASH SITE REVEALED THE PLANE WAS TRAVELING NEARLY PARALLEL WITH THE LEVEE WHEN IT CRASHED. GRASS (18 INCHES TALL) ON THE LEVEE HAD BEEN NEATLY SLICED PRIOR TO THE PRINCIPAL IMPACT. THE WIDTH OF THE SWATH MEASURED THE APRX WING SPAN OF THE LOWER WINGS. AFTER IMPACT, THE MAIN WRECKAGE TRAVELED ABOUT 100 FT BEFORE COMING TO REST. NO PREIMPACT/MECHANICAL PART FAILURE OR MALFUNCTION WAS EVIDENT.
