SANTA BARBARA, CA, USA

Aircraft #1

N20356

CESSNA 172

Analysis

THE AIRPLANE HAD BEEN OBSERVED FOR SEVERAL MINUTES FLYING VERY LOW OVER THE WATER. AT ONE POINT, IT STRUCK THE WATER BUT RECOVERED AND FLEW A BIT HIGHER ABOVE THE WATER FOR ANOTHER MILE. THE AIRPLANE DID NOT TURN TOWARD THE SHORELINE AND IT APPEARED TO GLIDE NOSE DOWN INTO THE WATER. THE STUDENT PILOT SAID HE WAS DESCENDING TOWARD THE WATER AT 400 TO 600 FPM WHEN THE ENGINE BACKFIRED. HE SAID THAT HE APPLIED CARBURETOR HEAT BUT THE ENGINE CONTINUED TO RUN ROUGH AND WOULD PRODUCE ONLY 1,200 RPM. HE FLEW AT THIS POWER SETTING FOR A MILE OR MORE, JUST ABOVE THE WATER, AND EVEN STRUCK THE TOPS OF THE WAVES AT TIMES. THE WHEELS STRUCK THE WATER AND THE AIRPLANE BOUNCED, AND THEN NOSED INTO THE WATER. THE WRECKAGE WAS NOT RECOVERED.

Probable Cause and Findings

THE IMPROPER INFLIGHT PLANNING/DECISIONS BY THE PLT WHEN HE DECIDED TO INTENTIONALLY FLY LOW OVER ROUGH WATER IN THE PACIFIC OCEAN AND THE PARTIAL LOSS OF POWER FOR UNDETERMINED REASONS.
