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.

Narrative: N2627N, a R-22B, helicopter on a VFR flight out of Boeing field, had partial engine failure. Aircraft landed in paramount park (near shoreline school at 155th and 10th in north Seattle). There was no damage to aircraft, and no injuries to pilot or passenger. Pilot is scott morgan who is an operator for classic helicopters. Pilot stated he felt a shudder in helicopter and he noticed the all engine instruments were in the green operating range. The pilot felt another shudder and he landed in paramount park as a precaution. The weather was VFR. The director of maintenance at classic helicopters performed troubleshooting procedures on the helicopter engine to determine the cause of the shudders. All engine systems were normal (ignition, fuel, oil, compression, etc.). The engine manufacturer was contacted and it was determined that the shudders were caused by carburetor ice. The atmospheric condition at the time of the incident were conducive to carburetor ice. The pilot was referred to the appropriate section of the R-22B flight manual which pertains to carburetor ice.
