# NTSB CHI07TA201: WSK PZL Mielec PZL M18B, N14067, Kyle, SD, July 7, 2007 - Type: NTSB accident investigation - Classification: Accident · Minor injuries · Final report - Date: July 7, 2007, 12:18 local (18:18 UTC) - Place: Kyle, SD - Coordinates: 43.3980555555556, -102.204722222222 - Nearby events: https://openairdocs.org/map.md?lat=43.3981&lon=-102.2047&mi=10 - Phase of flight: [Maneuvering](https://openairdocs.org/ntsb-phases/450) (OpenAirDocs' grouping) - Highest injury: Minor injuries - Injuries: 1 minor - Status: Completed, report March 31, 2008 - Report: Approved by Office Director - Parties: Federal Aviation Administration, U.S. Department of the Interior - NTSB case key (mKey): 66175 - NTSB case page: https://web.ntsb.gov/investigations/?ntsbnumber=CHI07TA201 - NTSB report (PDF, downloads): https://data.ntsb.gov/carol-repgen/api/Aviation/ReportMain/GenerateNewestReport/66175/pdf - Page: https://openairdocs.org/ntsb/CHI07TA201 ## Probable cause The pilot's failure to maintain clearance from terrain during an aerial application maneuver. Contributing to the accident were wind gusts, low altitude, and the reported downdraft. ## Sequence of events In NTSB's coding before 2008 (https://www.ntsb.gov/GILS/Documents/codman.pdf). - In flight collision with terrain/water, maneuvering - aerial application - weather condition - gusts (contributing factor) - altitude/clearance - not maintained, pilot in command (cause) - altitude - low (contributing factor) - weather condition - downdraft (contributing factor) ## Analysis The agricultural application airplane sustained substantial damage when it impacted terrain while maneuvering for a public use aerial application of fire retardant. The pilot stated that he was approaching a fire location from the northwest. He was crossing a "burnt area from west to east across gently rolling terrain." When he crossed a ridgeline, he encountered a downdraft and the airplane "wanted to settle." The pilot "pushed [the] nose over and released [the] load." The pilot stated that the airplane would not recover before impacting terrain. The pilot reported no mechanical malfunctions with the airplane in reference to the flight. Gusty winds were present in the area at the time of the accident. ## Factual narrative On July 7, 2007, about 1218 mountain daylight time, N14067, registered as a WSK PZL Meilec PZL M18B airplane, operated by the Department of the Interior, sustained substantial damage when it impacted terrain while maneuvering for an aerial application of fire retardant near Kyle, South Dakota.
