Factors relating to the accident were: the adverse weather conditions. ## Sequence of events In NTSB's coding before 2008 (https://www.ntsb.gov/GILS/Documents/codman.pdf). - In flight encounter with weather, approach - vfr pattern - final approach - in-flight planning/decision - improper, pilot in command (cause) - weather condition - thunderstorm,outflow (contributing factor) - weather condition - rain (contributing factor) - weather condition - unfavorable wind (contributing factor) - weather condition - downdraft (contributing factor) - flight into adverse weather - performed, pilot in command (cause) - Altitude deviation,uncontrolled, approach - vfr pattern - final approach - descent - uncontrolled - In flight collision with terrain/water, descent - uncontrolled ## Analysis THE PILOT STATED THAT HE CALLED THE CONTROL TOWER AT HIS DESTINATION AIRPORT SHORTLY AFTER TAKEOFF. HE SAID THE TOWER CONTROLLER TOLD HIM THERE WAS WEATHER ABOUT 5 MILES WEST. THE PILOT SAID HE ASSUMED THIS WAS THE SAME WEATHER DESCRIBED TO HIM DURING AN EARLIER CONVERSATION WITH THE SAME TOWER. AS THE AIRPLANE APPROACHED THE RUNWAY FOR LANDING, THE PILOT WAS ADVISED OF A WIND SHIFT AND RUNWAY CHANGE. HE SAID THAT WHEN THE AIRPLANE WAS 300 TO 400 FEET ABOVE THE GROUND, THE WIND 'JOLTED' THE AIRPLANE, '...PUSHING IT DOWN SHARPLY... .' THE AIRPLANE ENCOUNTERED A SECOND AND THIRD DOWNDRAFT. THE THIRD DOWNDRAFT FORCED THE AIRPLANE ONTO THE GROUND NORTH OF THE RUNWAY. THE PILOT SAID THE RAIN AND WIND THAT FOLLOWED THE ACCIDENT WERE INTENSE. AT 1915 CDT, TOWER PERSONNEL REPORTED THUNDERSTORMS WITH HEAVY RAIN SHOWERS AND 3/4 MILE VISIBILITY. ## Factual narrative On July 23, 1995, at 1910 central daylight time (cdt), a Cessna 172, N55212, piloted by a private pilot, was substantially damaged during a landing approach to runway 32 (5,600' X 150' wet asphalt) at the Springfield Regional Airport, Springfield, Missouri. Instrument meteorological conditions prevailed at the time of the accident. The personal 14 CFR Part 91 flight was not operating on a flight plan. The pilot and passenger reported no injuries. The flight departed from Ozark, Missouri, at 1800 cdt. According to the pilot's written statement on NTSB Form 6120.1/2, the purpose of the flight was to pick up a passenger at Ozark, Missouri. The pilot was preparing to depart Springfield, Missouri. Before departing, he said he noticed bluish colored clouds west of the airport. He asked the tower controller about the clouds and was told they were associated with rain northwest of the airport. The pilot said the controller advised him that the rain was moving in a northeasterly direction. He said he decided to depart based on the tower controller's report and the information he had obtained about his destination airport. He arrived at Ozark, Missouri, and picked up his passenger. After departing Ozark, Missouri, the pilot contacted the Springfield, Missouri, control tower. He said the controller advised him there was "...weather..." about 5 miles west of the airport. He said he assumed the weather was the rain he had been told about before departing Springfield, Missouri. About 2 minutes after the conversation the pilot was advised of a wind shift by the controller. The winds, according to the pilot, were reported to be "...350 degrees at 10 gusting to 16." The pilot said the controller was changing the active runway from runway 20 to 02. The controller offered the pilot runway 32 for his use when he was on a 2 mile final for runway 32. The pilot said his airplane was on short final for runway 32. He said the airplane was about 300 to 400 feet above the ground, "...when the wind jolted the airplane sharply, pushing us down." He said the airplane encountered a second downdraft that not only caused it to descend further, but also moved the airplane to the right. The pilot called the control tower and advised them that he was going to try to land on runway 02. A few moments later, the airplane encountered a third downdraft. This forced the airplane onto the ground about 200 to 300 yards north of runway 32, near runway 20. The pilot and passenger removed themselves from the wreckage as a "...torrent of rain began." According to the pilot, the wreckage cleanup had to be postponed about 30 minutes due to the rain and wind intensity. At 1915 cdt, the control tower reported thunderstorms with heavy rain showers, and 3/4 mile visibility. ## Aircraft - Registration: [N55212](https://openairdocs.org/deregistered/N55212-2012-07-31), registration cancelled 2012-07-31, S/N 17275136, built 1981 (OpenAirDocs) - Reported make and model: CESSNA 172 - Registry model: [Cessna 172P](https://openairdocs.org/model/cessna-172p) (registry code 2072436) (OpenAirDocs) - Registry engine: [Lycoming 0-320 series](https://openairdocs.org/engine/lycoming-0-320-series) (registry code 41508, reciprocating) (OpenAirDocs) - Category: Airplane - Serial number: 22-9309 - Engines: LYCOMING O-320-D2J 150 horsepower reciprocating - Damage: Substantial damage - Flight: Personal, Part 91 - Registered owner: Charles W.
