# NTSB DFW06CA109: Cessna 150M, N3419V, Roanake, TX, April 19, 2006 - Type: NTSB accident investigation - Classification: Accident · No injuries · Data collection · Final report - Date: April 19, 2006, 14:00 local (19:00 UTC) - Place: Roanake, TX - Coordinates: 32.95, -97.183334 - Nearby events: https://openairdocs.org/map.md?lat=32.9500&lon=-97.1833&mi=10 - Phase of flight: [Maneuvering](https://openairdocs.org/ntsb-phases/450) (OpenAirDocs' grouping) - Highest injury: No injuries - Injuries: 2 uninjured - Status: Completed, report July 31, 2006 - Report: Approved by Office Director - Parties: Federal Aviation Adminisration - NTSB case key (mKey): 63529 - NTSB case page: https://web.ntsb.gov/investigations/?ntsbnumber=DFW06CA109 - NTSB report (PDF, downloads): https://data.ntsb.gov/carol-repgen/api/Aviation/ReportMain/GenerateNewestReport/63529/pdf - Page: https://openairdocs.org/ntsb/DFW06CA109 ## Probable cause The pilot's failure to maintain clearance from an unmarked transmission wire. A contributing factor was the low altitude flight. ## Sequence of events In NTSB's coding before 2008 (https://www.ntsb.gov/GILS/Documents/codman.pdf). - In flight collision with object, maneuvering - emergency procedure - simulated, pilot in command(cfi) - low altitude flight/maneuver - selected, pilot in command (contributing factor) - object - wire,transmission - clearance - not maintained, pilot in command(cfi) (cause) - Loss of control - in flight, descent - uncontrolled - In flight collision with terrain/water, descent - uncontrolled - terrain condition - ground ## Analysis The left main landing gear of the single-engine airplane collided with an unmarked guide wire during a simulated forced landing. The 6,130-hour flight instructor reported that while on the crosswind leg of the traffic pattern, while at about 600 feet above ground level (agl), he applied engine carburetor heat, reduced the engine power to idle, and asked the 156-hour student pilot to perform a simulated emergency power-off forced landing. As the two-seat single-engine airplane was descending, the flight instructor asked for the flight controls in order to "demonstrate a secondary field for landing" to the pilot receiving instruction. During the demonstration, the airplane's left main landing gear contacted an unmarked static transmission wire which resulted in a loss of control and an uncontrolled descent to the ground. The airplane impacted the ground with the outboard section of the right wing and came to rest in an inverted position. There was no postimpact fire and both occupants were able to exit the airplane unassisted. The flight instructor reported that there was no mechanical malfunction or failure with the airplane prior to the accident. ## Factual narrative The left main landing gear of the single-engine airplane collided with an unmarked guide wire during a simulated forced landing.

Aircraft are matched to registry aircraft by N-number and event date, checked against the reported serial number, make and model; the registry's history has gaps, so older matches can be wrong.
