## Narrative

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

(-23) ON SEPTEMBER 9, 2004, AT APPROXIMATELY 1020 LOCAL TIME, N994RW (ROBINSON R-22 HELICOPTER) CRASHED AND WAS DESTROYED WHILE PRACTICING 180 DEGREE AUTOROTATIONAL DESCENTS TO POWER RECOVERIES. THE PILOT-IN-COMMAND (QUALIFIED FLIGHT INSTRUCTOR), ANDREW R. ISOM, WAS FLYING N994RW WHEN THE ACCIDENT OCCURRED. THIS CFI TOOK CONTROL OF THE MANEUVER WHEN THE STUDENT APPLIED INCORRECT THROTTLE APPLICATION. DURING THE 180 TURN N994RW WAS APPARENTLY ENTERED INTO A HIGH RATE OF DESCENT AND THIS CFI WAS UNABLE TO GAIN CONTROL BEFORE IMPACTING RUNWAY 12L AT VGT. NTSB AUTHORIZED REMOVAL OF N994RW TO A SECURE LOCATION AND WAS INSPECTED BY AN AW INSPECTOR FROM LAS.
