## Narrative

As the FAA filed it, in capitals; the FAA replaces private details with ^PRIVACY DATA OMITTED^.

(-23) AIRCRAFT WAS SEARCHING FOR A COMPANY OVERDUE HELICOPTER WHEN THE PILOT HEARD THAT ANOTHER COMPANY HELICOPTER INVOLVED IN THE SEARCH HAD CRASHED. AFTER A PERIOD OF SEARCHING, MR. HEHR LOCATED THE DOWNED HELICOPTER, AND LOADED THE UNINJURED PILOT AND PASSENGER INTO HIS HELICOPTER. THEY DEPARTED THE CRASH SITE AND CONTINUED THE SEARCH FOR THE INITIAL MISSING HELICOPTER. MR. HEHR SEARCHED FOR ABOUT 30 MINUTES BEFORE SPOTTING THE INITIAL HELICOPTER CRASH SITE. ON THE ENROUTE TO THE LOCATION, THE HELICOPTER STRUCK A SNOW-COVERED ICE RIDGE. THE HELICOPTER SKIDS IMPACTED FIRST, CAUSING THE SHIP TO SOMERSAULT.
