## Narrative

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

(-23) AT APPROXIMATELY 0830 HOURS PST ON 3/26/2005, ROBINSON R-22 BETA HELICOPTER, N820SH, SUSTAINED SUBSTANTIAL DAMAGE WHEN THE ENGINE FAILED DURING AN ATTEMPTED POWER RECOVERY FROM AN AUTOROTATION. THE FLIGHT INSTRUCTOR (PIC) AND CFI-APPLICANT (STUDENT) WERE ENROUTE FROM GUSTINE, CA (3O1) TO LAS BANOS, CA (LSN) ON A 14CFR91 INSTRUCTIONAL FLIGHT IN VMC CONDITIONS. APPROXIMATELY 5 NM NORTH OF LSN, THE PIC INITIATED A SIMULATED FORCED LANDING AT 900' AGL AND 80 KIAS BY REDUCING ENGINE POWER TO IDLE WITH THE THROTTLE. THE STUDENT ENTERED AUTOROTATION, APPLIED CARBURETOR HEAT, AND MANEUVERED TOWARD A SUITABLE FORCED LANDING SITE. DURING THE AUTOROTATIVE FLARE THE STUDENT INITIATED A POWER RECOVERY TO TERMINATE THE MANEUVER TO A HOVER. THE ENGINE RESPONDED INITIALLY TO THE DEMAND FOR POWER, THEN LOST POWER COMPLETELY. THE HELICOPTER LANDED HARD AND BOUNCED ONCE IN A SKIDS LEVEL ATTITUDE WITH APPROXIMATELY 5 KNOTS FORWARD SPEED. THE LEFT SKID TOE CONTACTED A TUSSOCK CAUSING THE AIRCRAFT TO YAW LEFT 90 DEGREES. THE HELICOPTER BOUNCED A SECOND TIME AND CAME TO REST UPRIGHT ON ITS SKIDS. THE PIC AND STUDENT WERE NOT INJURED.

## The NTSB's investigation of this event (1)

From the NTSB's public API. Aircraft are matched to registry aircraft by N-number and event date, checked against the reported serial number, make and model; the registry's history has gaps, so older matches can be wrong. Compare the reported make and model.

Probable cause: the instructor pilot's failure to apply carburetor heat during a simulated engine failure, which resulted in a total loss of engine power due to carburetor icing.
