## Analysis

AT THE END OF A PLEASURE CROSS COUNTRY FLT, WHILE ON LONG FINAL TO THE RWY, THE PLT HAD TO ADD PWR TO COMPENSATE FOR A CROSSWIND. PRIOR TO REACHING SHORT FINAL THE PLT HAD REDUCED PWR AGAIN. UPON REACHING THE THRESHOLD, THE ACFT WAS APRX 300 FT AGL. THE PLT DECIDED TO GO-AROUND. PWR WAS RAPIDLY ADDED AND THE CARBURETOR HEAT TURNED OFF. THE ENGINE AT THIS TIME ONLY DEVELOPED PARTIAL PWR. THE PLT THEN ADDED CARBURETOR HEAT AGAIN. THE ENGINE, STILL NOT DEVELOPING SUFFICIENT PWR TO MAINTAIN ALTITUDE WAS DESCENDING AT 50-100 FPM. THE PLT THEN LANDED THE ACFT BEYOND MIDFIELD AND BOUNCED SEVERAL TIMES BEFORE RUNNING OFF THE RUNWAY AND COLLIDED WITH THE TERRAIN.

## FAA reports on this event (1)

The FAA's own accident and incident reports, matched to the aircraft by N-number and date (OpenAirDocs).

- [Accident 19870417010339A](https://openairdocs.org/incident/19870417010339A), Apr 17, 1987: Cessna 182M, Mammoth Lakes, CA, Substantial damage. The aircraft overran the runway during landing. Pilot attempted to go around but advanced throttle too rapidly.

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.
