From the FAA’s Accident/Incident Data System (AIDS), through its Aviation Safety Information Portal, as reported. The NTSB investigates accidents separately, and its record of an accident is the fuller one. The aircraft is matched to the registry by N-number and event date, checked against the reported make and model; the registry’s history has gaps, so older matches can be wrong. Compare the reported make and model.

What happened

The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.

(-23) The pilot stated in a telephone interview that approximately five to six minutes after departing compton airport, he attempted to lean the engine mixture. As he moved the carburetor mixture control, the engine began to cough and sputter with a significant partial loss power. The pilot made an autorotation to a successful emergency landing in a schoolyard. During the autorotation the engine maintained only partial power. Upon the aircraft coming to a stop, the engine began to operate normally. The pilot allowed rotor RPM to climb to 100%. In an attempt to ground maneuver the aircraft, two rotor blades struck a large lamb of a tree. This resulted in damage to two blades and the loss of blade balance weights of the two damaged blades. The aircraft was being operated on a special flight permit from compton airport and compton California to mesa Arizona where an annual inspection was scheduled to be performed. The owner of the aircraft privacy data omitted has not cooperated by permitting the removal and inspection of the engine carburetor and fuel pump assemblies. At this point the reason for the partial loss of power has not been determined.
