# NTSB DFW07CA163: Cessna 172M, N13441, Throckmorton, TX, July 16, 2007 - Type: NTSB accident investigation - Classification: Accident · No injuries · Data collection · Final report - Date: July 15, 2007, 20:00 local (Jul 16, 2007, 01:00 UTC) - Place: Throckmorton, TX - Coordinates: 33.173053, -99.121665 - Nearby events: https://openairdocs.org/map.md?lat=33.1731&lon=-99.1217&mi=10 - Phase of flight: [Emergency descent](https://openairdocs.org/ntsb-phases/600) (OpenAirDocs' grouping) - Highest injury: No injuries - Injuries: 2 uninjured - Status: Completed, report November 29, 2007 - Report: Approved by Office Director - Parties: Fort Worth, Texas - NTSB case key (mKey): 66252 - NTSB case page: https://web.ntsb.gov/investigations/?ntsbnumber=DFW07CA163 - NTSB report (PDF, downloads): https://data.ntsb.gov/carol-repgen/api/Aviation/ReportMain/GenerateNewestReport/66252/pdf - Page: https://openairdocs.org/ntsb/DFW07CA163 ## Probable cause The pilot's failure to maintain clearance from power transmission lines. A contributing factor was the prevailing dusk illumination. ## Sequence of events In NTSB's coding before 2008 (https://www.ntsb.gov/GILS/Documents/codman.pdf). - In flight collision with object, emergency descent/landing - light condition - dusk (contributing factor) - clearance - not maintained, pilot in command (cause) - object - wire,transmission - Loss of control - in flight, emergency descent/landing - Nose over, emergency landing - terrain condition - ground ## Analysis The single-engine airplane collided with power lines while the pilot was demonstrating a simulated forced landing. Following the impact with the power lines, the pilot was able to land the airplane in a field. During the landing roll, the airplane nosed-over and came to rest in the inverted position. There was no fire. In a telephone interview, the pilot reported that he was demonstrating a simulated loss of engine power and forced landing procedures to his passenger. During the low approach to a pre-selected field, the aircraft collided with unmarked power transmission lines. The accident occurred at dusk. There were no reported discrepancies with the aircraft prior to the mishap. ## Factual narrative The single-engine airplane collided with power lines while the pilot was demonstrating a simulated forced landing.
