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.

(.19) On March 25, 2001, ap approx. 1200 MST, a Bell UH-1H helicopter, N56CF, was substantially daamged when it collided with the terrain during an emergency landing near Zuni, NM. The commercial pilot and sole occupant was not injured. Visual meteorological conditions prevailed for this ferry flight being conducted under title 14 CFR part 91. The flight originated from albuquerque, NM at approx. 1100. According to the pilot, he noticed a high engine oil temperature. A few moments later, he received a report from a pilot in a second helicopter telling him that his engine was on fire. The pilot shut-down the engine, intiated an autorotation, and the helicopter impacted the ground hard. The fire stopped prior to landing. The helicopter sustained substantial damage to the landing gear/skids, belly and fire damage to the engine. (-23) on March 25, 2001, approx. 1200 MST, N56CF, a Bell UH-1H helicopter, received substantial damage during an emergency landing near Zuni, NM. The pilot was the sole occupant and received no injuries. According to the pilot, he saw an increase in oil temp, followed by the pilot followed by the pilot behind him (in another a/c) reporting that N56CF'S engine was on fire the pilot shutdown the engine and executed an autorotation. The a/c hit the ground hard, damaging the skids an dbelly. (.4) on March 25, 2001, at approximately 1330 mountain standard time, a Bell UH-1H helicopter, N56CF, was substantially damaged when it collided with the terrain during an emergency landing near Zuni, new Mexico. The commercial pilot and sole occupant was not injured. Visual meteorological conditions prevailed for this ferry flight being conducted under title 14 CFR part 91. The flight originated from double eagle ii airport, albuquerque, new Mexico, at approximately 1230. According to the pilot, he noticed an illuminated master caution light and high engine oil temperature. A few moments later, he received a report from a pilot in a second helicopter telling him that his engine was on fire. The pilot then noticed an engine chip light. He shut down the engine and "initiated an autorotation." The engine seized at approximately 200 feet above ground level (AGL) and the helicopter hit the ground hard. The pilot stated that he "elected to run the a/c on because of the altitude (7,800') and being downwind. The landing worked out fine until the skids grabbed in the soft dirt and collapsed." The helicopter sustained substantial damage to the skids, bottom of fuselage and fire damage to the engine. The fire extinguished prior to landing. An examination of the engine at a helicopter repair station in redding, California, identified that the "engine's number three and four bearing pack seal had failed." The failure resulted in "high engine oil temperature, which led to the engine fire and subsequent failure of the engine."
