The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.
(-23) Pursuant to conditions contained within FAA issued operating limitations, pilot was conducting test flights comprised of various acrobatic maneuvers. At 4000 AGL level flight, upon completion of a gradual right turn, the engine ceased operation. According to pilot interview, fuel pressure was ormal (6PSI) and oil pressure in green band. Wall pump activation indicated fuel pressure at maximum. Engine failed to restart. Pilot initiated an immediate landing in a grass field 1 mile NE of Creswell, Oregon. Terrain was heavily grown and ground was soft. Aircraft gear collapsed upon landing, flipped and came to rest in an inverted attitude. The fuselage sustained substantial damage to the stabilizers, the upper wing structural supports and the leading edge spar.
