The pilot stated local winds were from 200 degrees at 15 knots gusting to 21 knots. The airplane touched down 1,000 feet down the runway and traveled off the end where it contacted a barbed wire fence and a 4 foot deep ditch prior to coming to a stop. Winds reported at Des Moines, Iowa, 47 miles west of the accident site, nine minutes after the accident, were from 200 degrees at 16 knots gusting to 22 knots. ## Factual narrative On July 14, 1999, at 1445 central daylight time, a Cessna 172L, N19752, collided with a fence and rough terrain during an overrun landing on runway 36 (2,600' x 105') at the Sig Field, Montezuma, Iowa. The private pilot and a passenger were not injured. The airplane was substantially damaged. The 14 CFR Part 91 personal flight was being operated in visual meteorological conditions without a flight plan. The flight departed from Ankeny, Iowa, at 1410 cdt. The pilot reported he made radio calls announcing that he was landing on runway 18; however, he inadvertently entered the traffic pattern for runway 36. The pilot stated that local winds were from 200 degrees at 15 knots gusting to 21 knots. He continued to report, "Without remembering the wind I continued the pattern for 36." The pilot stated the airplane touched down approximately 1,000 feet down the runway. He was unable to stop the airplane before it traveled off the end of the runway, through a barbed wire fence, and into a 4 foot deep ditch. Winds reported at Des Moines, Iowa, 47 miles west of the accident site, at 1454 cdt, were from 200 degrees at 16 knots gusting to 22 knots. ## Aircraft - Registration: [N19752](https://openairdocs.org/aircraft/N19752), registered now, S/N 17260722, built 1972 (OpenAirDocs) - Reported make and model: Cessna 172L - Registry model: [Cessna 172L](https://openairdocs.org/model/cessna-172l) (registry code 2072432) (OpenAirDocs) - Registry engine: [Lycoming 0-320 series](https://openairdocs.org/engine/lycoming-0-320-series) (registry code 41508, reciprocating) (OpenAirDocs) - Category: Airplane - Serial number: 17260722 - Airframe hours: 7137 - Engines: Lycoming O-320-E2D 150 horsepower reciprocating - Damage: Substantial damage - Flight: Personal, Part 91 - Registered owner: Magic Aviation LLC - Airworthiness certificate: Standard, Normal - Departed: IKV, ANKENY, IA - Destination: SIG - Airport: 7C5, Sig Field, runway 36, 2,600 × 105 ft, grass/turf ## Flight crew As NTSB recorded them.
