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.

On 08/18/ 2022, the pilotprivacy data omitted of a 1976 Aerospatiale gazelle sa 342 helicopter was flying the helicopter on a part 91 personal flight when he crashed while making an approach to a mountain cabin area at approximately 7,400 feet MSL. The tail number was identified as privacy data omitted. The pilot had been helping a friend haul supplies from a pickup point at approximately 5,000 feet MSL up to the friends? Cabin area at 7,400 feet MSL. The pilot had a passenger onboard during the entire operation. The passenger was not a certificated pilot. The pilot completed approximately 11 loads to the cabin throughout the day and made two re-fuel stops before crashing on approach with the 11th load.

The pilot stated that while on approach with the 11th and final load to the cabin area, the aircraft felt heavier than the previous loads. He noted that the weather conditions had changed as well. For the majority of the day he had been working with a cloud layer that keep the temperatures cooler. On the final load he noted that the outside air temperature had increased. The pilot mentioned to his passenger that he would make a shallow and slow approach due to the heavy feeling of the aircraft. The pilot stated that he made his approach to the landing area at approximately 150 feet per minute rate of descent and an airspeed of approximately 30 knots. At approximately 25 to 30 feet AGL the pilot experienced a sink rate with the aircraft that began to increase quickly. The pilot applied maximum collective power but was unable to stop the sink rate. The pilot stated that he immediately decided to perform a run-on landing to the intended landing area. The pilot performed a run-on landing to a sandy area and slid several feet. The pilot stated that during the run-on landing, the aircraft tipped forward on the nose of the aircraft causing the main rotor blades to strike the ground. The momentum of the main rotors striking the ground made the helicopter spin 180 degrees to the left causing severe damage to several aircraft components. The pilot stated that he immediately performed an emergency shut-down of the engine. The aircraft remained upright after the crash and both the pilot and the passenger exited the aircraft unharmed.

ON 08/18/ 2022, THE PILOT^PRIVACY DATA OMITTED^ OF A 1976 AEROSPATIALE GAZELLE SA 342 HELICOPTER WAS FLYING THE HELICOPTER ON A PART 91 PERSONAL FLIGHT WHEN HE CRASHED WHILE MAKING AN APPROACH TO A MOUNTAIN CABIN AREA AT APPROXIMATELY 7,400 FEET MSL. THE TAIL NUMBER WAS IDENTIFIED AS ^PRIVACY DATA OMITTED^. THE PILOT HAD BEEN HELPING A FRIEND HAUL SUPPLIES FROM A PICKUP POINT AT APPROXIMATELY 5,000 FEET MSL UP TO THE FRIENDS? CABIN AREA AT 7,400 FEET MSL. THE PILOT HAD A PASSENGER ONBOARD DURING THE ENTIRE OPERATION. THE PASSENGER WAS NOT A CERTIFICATED PILOT. THE PILOT COMPLETED APPROXIMATELY 11 LOADS TO THE CABIN THROUGHOUT THE DAY AND MADE TWO RE-FUEL STOPS BEFORE CRASHING ON APPROACH WITH THE 11TH LOAD.

THE PILOT STATED THAT WHILE ON APPROACH WITH THE 11TH AND FINAL LOAD TO THE CABIN AREA, THE AIRCRAFT FELT HEAVIER THAN THE PREVIOUS LOADS. HE NOTED THAT THE WEATHER CONDITIONS HAD CHANGED AS WELL. FOR THE MAJORITY OF THE DAY HE HAD BEEN WORKING WITH A CLOUD LAYER THAT KEEP THE TEMPERATURES COOLER. ON THE FINAL LOAD HE NOTED THAT THE OUTSIDE AIR TEMPERATURE HAD INCREASED. THE PILOT MENTIONED TO HIS PASSENGER THAT HE WOULD MAKE A SHALLOW AND SLOW APPROACH DUE TO THE HEAVY FEELING OF THE AIRCRAFT. THE PILOT STATED THAT HE MADE HIS APPROACH TO THE LANDING AREA AT APPROXIMATELY 150 FEET PER MINUTE RATE OF DESCENT AND AN AIRSPEED OF APPROXIMATELY 30 KNOTS. AT APPROXIMATELY 25 TO 30 FEET AGL THE PILOT EXPERIENCED A SINK RATE WITH THE AIRCRAFT THAT BEGAN TO INCREASE QUICKLY. THE PILOT APPLIED MAXIMUM COLLECTIVE POWER BUT WAS UNABLE TO STOP THE SINK RATE. THE PILOT STATED THAT HE IMMEDIATELY DECIDED TO PERFORM A RUN-ON LANDING TO THE INTENDED LANDING AREA. THE PILOT PERFORMED A RUN-ON LANDING TO A SANDY AREA AND SLID SEVERAL FEET. THE PILOT STATED THAT DURING THE RUN-ON LANDING, THE AIRCRAFT TIPPED FORWARD ON THE NOSE OF THE AIRCRAFT CAUSING THE MAIN ROTOR BLADES TO STRIKE THE GROUND. THE MOMENTUM OF THE MAIN ROTORS STRIKING THE GROUND MADE THE HELICOPTER SPIN 180 DEGREES TO THE LEFT CAUSING SEVERE DAMAGE TO SEVERAL AIRCRAFT COMPONENTS. THE PILOT STATED THAT HE IMMEDIATELY PERFORMED AN EMERGENCY SHUT-DOWN OF THE ENGINE. THE AIRCRAFT REMAINED UPRIGHT AFTER THE CRASH AND BOTH THE PILOT AND THE PASSENGER EXITED THE AIRCRAFT UNHARMED.
