# NTSB CHI00LA257: Ayres S2R-600, N3103B, Bad Axe, MI, August 14, 2000 - Type: NTSB accident investigation - Classification: Accident · Fatal · Limited investigation · Final report - Date: August 14, 2000, 10:20 local (14:20 UTC) - Place: Bad Axe, MI - Coordinates: 43.799823, -82.990875 (estimated) - Nearby events: https://openairdocs.org/map.md?lat=43.7998&lon=-82.9909&mi=10 - Phase of flight: [Maneuvering](https://openairdocs.org/ntsb-phases/450) (OpenAirDocs' grouping) - Highest injury: Fatal - Injuries: 1 fatal - Status: Completed, report July 26, 2001 - Report: Approved by Office Director - NTSB case key (mKey): 50002 - NTSB case page: https://web.ntsb.gov/investigations/?ntsbnumber=CHI00LA257 - NTSB report (PDF, downloads): https://data.ntsb.gov/carol-repgen/api/Aviation/ReportMain/GenerateNewestReport/50002/pdf - Page: https://openairdocs.org/ntsb/CHI00LA257 ## Probable cause The inadvertent stall/spin encountered by the pilot. A factor was the low altitude. ## Sequence of events In NTSB's coding before 2008 (https://www.ntsb.gov/GILS/Documents/codman.pdf). - Loss of control - in flight, maneuvering - aerial application - stall/spin - inadvertent, pilot in command (cause) - altitude - low (contributing factor) - In flight collision with terrain/water, descent - uncontrolled ## Analysis The airplane was performing an aerial application flight when it impacted the ground while making a turn at the end of a spray pass. Witnesses to the accident reported that they saw the aircraft making a turn at the end of northbound pass. One of the witnesses reported that during the turn, "...the left wing dropped, nose went down, and the aircraft spun to the left." A second witness reported that, "...in the middle of the turn about that the plane seemed to be turning a little to[o] sharp. He was flying north turning to the west when about halfway is when it dipped real bad and made about 3/4 of a revolution and came nose first into the ground." The witness also stated that he did not hear a difference in engine sound when the accident occurred. A third witness reported that the aircraft, "...turned right then left at about 2/3 of the way around the plane seemed to turn real sharp then turned over and spiraled to the ground. A fourth witness reported that the aircraft was, "...spraying from south to north, and was in the process of making a turn to his left and was starting to come out of the turn when the plane started to roll or spin down. I could hear the engine thru out the spraying process and the sound of the engine never seem[ed] to change thru out this period." A postaccident examination of the aircraft did not reveal any anomalies that could be associated with a preexisting condition. ## Factual narrative HISTORY OF FLIGHT On August 14, 2000, at 1020 eastern daylight time, an Ayers S2R-600, N3103B, piloted by a commercial pilot, was destroyed on impact with terrain while maneuvering near Bad Axe, Michigan.
