NTSB narrative
THE EMS HELICOPTER ENCOUNTERED CLEAR AIR TURBULENCE WHILE EN ROUTE TO PICK UP A PATIENT. DURING THE EVENT, THE NOSE PITCHED UP RAPIDLY TO ABOUT 20 DEGREES, ACTIVATING THE ELT. THE PILOT FELT FEEDBACK THROUGH THE CONTROLS AND LANDED TO RESET THE ELT. LATER, THE PILOT NOTED MAST TORQUE FLUCTUATIONS FOLLOWED BY A ZERO READING ON THE GAUGE. POSTFLIGHT INSPECTION DISCLOSED THE TRANSMISSION HAD CONTACTED ITS MOUNTS, SEVERING SEVERAL ELECTRICAL LEADS INCLUDING THE TORQUE SENSOR. A CRACK WAS ALSO DISCOVERED ABOUT 2 1/2 FEET OUTBOARD OF THE MAIN BLADE GRIP, PROPAGATING BACK FROM THE BLADE LEADING EDGE.

- Unreviewed is an editorial label, not an investigation status. API-sourced is not report-checked or human-reviewed. Explicit event totals are used without summing aircraft injury tables; onboard allocation is withheld. Unknown values remain unknown. The operation category is mapped from the NTSB-reported FAR part and has not been reviewed.
- Filled from the NTSB case API where the bulk record had no value: investigation status. Values present in the bulk record are kept.
- The date is the local date, which is the same as the UTC date the NTSB stores.
