# NTSB DFW06CA168: Cessna TU206G, N5424X, Eldorado, TX, June 27, 2006 - Type: NTSB accident investigation - Classification: Accident · No injuries · Data collection · Final report - Date: June 27, 2006, 10:59 local (15:59 UTC) - Place: Eldorado, TX - Coordinates: 30.8622222222222, -100.610833333333 - Nearby events: https://openairdocs.org/map.md?lat=30.8622&lon=-100.6108&mi=10 - Phase of flight: [Approach](https://openairdocs.org/ntsb-phases/500) (OpenAirDocs' grouping) - Highest injury: No injuries - Injuries: 2 uninjured - Status: Completed, report October 3, 2006 - Report: Approved by Office Director - NTSB case key (mKey): 63995 - NTSB case page: https://web.ntsb.gov/investigations/?ntsbnumber=DFW06CA168 - NTSB report (PDF, downloads): https://data.ntsb.gov/carol-repgen/api/Aviation/ReportMain/GenerateNewestReport/63995/pdf - Page: https://openairdocs.org/ntsb/DFW06CA168 ## Probable cause The pilot's failure to maintain airspeed during an emergency simulation resulting in a hard landing. A contributing factor was the flight instructor's delayed remedial action. ## Sequence of events In NTSB's coding before 2008 (https://www.ntsb.gov/GILS/Documents/codman.pdf). - Forced landing, approach - vfr pattern - downwind - emergency procedure - simulated, pilot in command(cfi) - Hard landing, landing - airspeed - not maintained, pilot in command (cause) - remedial action - delayed, pilot in command(cfi) (contributing factor) ## Analysis During a training flight, while at 90 knots and 750 feet above the ground, on a left downwind for runway 35, the 6,250-hour flight instructor reduced the airplane's engine power to idle, and asked the 7,237-hour airline transport pilot to perform a simulated forced landing. The pilot proceeded to complete his loss of engine power emergency checklist as he turned the airplane towards the runway. The airplane settled into a descent rate of 600 to 800 feet per minute (FPM). While at approximately 75 to 100 feet above ground level (AGL), while at an indicated airspeed of 78 knots, the pilot "began increasing the [engine] throttle to maximum [power]" to arrest a developing high rate of descent. The engine reportedly did not respond. Subsequently, the airspeed continued to decay and the airplane landed hard approximately 85 feet beyond the landing threshold. The nose landing gear collapsed and the airplane exited the edge of the 60-foot wide runway before coming to rest in the upright position. Both pilots were able to egress the airplane unassisted. An examination of the airplane's engine and flight controls did not reveal any pre-impact anomalies. The wind at the time of the mishap was reported as variable at 6 knots, and the density altitude was estimated at 3,000 feet. ## Factual narrative During a training flight, while at 90 knots and 750 feet above the ground, while on the left downwind for runway 35, the 6,250-hour flight instructor reduced the airplane's engine power to idle, and asked the 7,237-hour airline transport pilot to perform a simulated forced landing.

(-23) Public use aircraft investigated by homeland security, no other data available. From the NTSB's public API. 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.
