The NTSB's narrative final · quoted from the NTSB record
THE HOME BUILT, POWERED GLIDER WAS BEING FLOWN ON A LOCAL TEST FLIGHT. ACCORDING TO WITNESSES, THE ACFT WAS IN UNPOWERED FLT (GLIDING) WHEN IT ENTERED A DESCENT & CRASHED. AT ABOUT THE SAME TIME IT BEGAN DESCENDING, THEY OBSERVED SOMETHING SEPARATE FROM THE ACFT THAT APPEARED TO BE A WING. AN EXAM OF THE WRECKAGE REVEALED THE LEFT WING SKIN HAD SEPARATED FROM THE SPAR. THE LEFT SPAR WAS STILL ATTACHED TO THE FUSELAGE AND WAS BENT & TWISTED TOWARD THE TIP. THE ACFT HAD COME TO REST INVERTED & BOTH STABILIZERS OF THE V-TAIL HAD BROKEN. THE LEFT STABILIZER & LEFT WING SKIN WERE FOUND 185 & 300 FT, RESPECTIVELY, FROM THE MAIN WRECKAGE. AN INSPECTION OF THE LEFT WING REVEALED THAT THE SKIN HAD BEEN ATTACHED TO THE RIBS, BUT HAD NOT BEEN BONDED TO THE SPAR. ACCORDING TO THE ASSEMBLY INSTRUCTIONS, THE SKIN SHOULD HAVE BEEN BOND WITH EPOXY TO BOTH THE TOP & BOTTOM OF THE SPAR.
