Analysis

THE PILOT BEGAN A LANDING ON A 2900 FOOT RUNWAY WITH A LEFT CROSSWIND OF 10 TO 15 KNOTS, GUSTING 15 TO 20 KNOTS. THE APPROACH TO THE RUNWAY WAS OVER TREES AND ELECTRICAL WIRES. THE PILOT SAID THAT HE MADE THE APPROACH WITH A LOW POWER SETTING, FULL FLAPS, AND WITH THE CARBURETOR HEAT ON. AS HE WAS ABOUT TO LAND, THERE WAS A SUDDEN LOSS OF AIRSPEED AND THE AIRPLANE DROPPED TO THE GROUND AND BOUNCED. THE PILOT 'APPLIED POWER TO EFFECT A GO AROUND TO LAND A LITTLE FURTHER DOWN THE RUNWAY.' HE SAID THE AIRPLANE SEEMED TO WEATHERVANE INTO THE WIND AND BEGAN TO DRIFT TO THE LEFT OVER PLOWED GROUND TOWARD TREES. HE TRIED TO ALIGN THE FLIGHT PATH MORE IN THE DIRECTION OF THE RUNWAY; HOWEVER, THE AIRCRAFT SETTLED AND IMPACTED THE PLOWED GROUND ABOUT 200 TO 300 FEET LEFT OF THE RUNWAY. A POST-ACCIDENT EXAMINATION OF THE AIRPLANE FAILED TO REVEAL ANY PREEXISTING ANOMALIES.

Factual Information

On October 27, 1993, at 1415 central daylight time, a Cessna 170B, N2923D, registered to Richard J. Cherba, and operated by a airline transport rated pilot, experienced a loss of control during an aborted landing attempt and impacted in a plowed field adjacent to runway 29 at Maple Plain, Minnesota. The airplane sustained substantial damage. The pilot reported no injuries. The personal 14 CFR Part 91 flight was operating in visual meteorological conditions. No flight plan was on file. The flight departed Saint Cloud, Minnesota, at 1140. The pilot stated that the airplane touched down "firm" and he attempted to abort the landing. The airplane turned to the left. Seeing a tree line coming up the pilot attempted to turn right more in line with the direction of the runway, and the airplane impacted in a plowed field. A post accident examination of the airplane and engine failed to reveal any pre-existing anomalies.

Probable Cause and Findings

THE PILOT'S IMPROPER COMPENSATION FOR WIND CONDITIONS, FAILURE TO MAINTAIN RUNWAY ALIGNMENT, AND FAILURE TO MAINTAIN ADEQUATE AIRSPEED DURING THE ABORTED LANDING. FACTORS RELATED TO THE ACCIDENT WERE: HIGH OBSTRUCTIONS AND THE ADVERSE WIND CONDITIONS.
