# NTSB DFW07LA052: Fairchild Merlin SA-226-T, Tulsa, OK, January 2, 2007 - Type: NTSB accident investigation - Classification: Accident · No injuries · Limited investigation · Final report - Date: January 2, 2007, 11:40 local (17:40 UTC) - Place: Tulsa, OK - Coordinates: 36.038333, -95.984443 - Nearby events: https://openairdocs.org/map.md?lat=36.0383&lon=-95.9844&mi=10 - Phase of flight: [Landing](https://openairdocs.org/ntsb-phases/550) (OpenAirDocs' grouping) - Highest injury: No injuries - Injuries: 9 uninjured - Status: Completed, report December 20, 2007 - Report: Approved by Office Director - Parties: FAA FSDO - NTSB case key (mKey): 65127 - NTSB case page: https://web.ntsb.gov/investigations/?ntsbnumber=DFW07LA052 - NTSB report (PDF, downloads): https://data.ntsb.gov/carol-repgen/api/Aviation/ReportMain/GenerateNewestReport/65127/pdf - Page: https://openairdocs.org/ntsb/DFW07LA052 ## Probable cause The loss of control as result of the malfunction of the nose wheel steering mechanism during landing for undetermined reasons. ## Sequence of events In NTSB's coding before 2008 (https://www.ntsb.gov/GILS/Documents/codman.pdf). - Loss of control - on ground/water, landing - roll - directional control - not possible, pilot in command - landing gear,nose gear - uncommanded - landing gear,steering system - failure (cause) - Nose gear collapsed, landing - roll - landing gear,nose gear - collapsed ## Analysis The twin pressurized turboprop airplane veered to the left and departed the runway during landing on runway 19R. Runway 19R was reported to be a 5,102-foot long by 100-foot wide asphalt runway. The airplane came to rest on the grass between runway 13 and taxiway Juliet. The pilot reported that following a normal full-flap landing, the airplane started to veer to the left as soon as the nose wheel tires touched down on the runway. The pilot was not able to compensate for the uncommanded drift as result of the nose wheel steering mechanism. The airplane sustained structural damage to the nose section & nose wheel assembly. The 7 passengers and 2 crewmembers egressed the airplane normally and sustained no injuries. The reason for the uncommanded left drift could not be determined. A completed NTSB Form 6120.1 was not received from either one of the pilots nor the operator. The weather was reported as calm winds, 10 statute miles visibility, clear skies, temperature 45 degrees Fahrenheit, dew point 28 degrees Fahrenheit, and a barometric pressure setting of 30.41 inches of Mercury. ## Factual narrative On January 2, 2007, at 1140 central standard time, a twin-engine Fairchild Merlin SA-226-T airplane, Venezuelan registration YV-2045, was substantially damaged following a loss of control while landing at the Richard L. Jones Jr. Airport (KRVS) near Tulsa, Oklahoma. The airplane was owned and operated by a private individual in Caracas, Venezuela. The airline transport rated pilot, the commercial pilot functioning as first officer, and the 7 passengers were not inured. Visual meteorological conditions for the 14 Code of Federal Regulations Part 91 business flight. The flight originated at the Fort Lauderdale Executive Airport (KFXE), near Fort Lauderdale, Florida, at 0740, with KRVS as its intended destination. Tower personnel reported that the twin-engine airplane veered to the left and departed the runway during the landing roll on Runway 19R. Runway 19R was reported to be a 5,102-feet long, by 100-feet wide asphalt runway. The airplane came to an abrupt stop in the grassy area between Runway 13 and Taxiway Juliet, after the nose landing gear assembly dug into the soft ground and collapsed. The pilot reported that following a "normal" full-flap landing, he was unable to maintain directional control of the airplane due to the failure of the nose wheel steering mechanism. The airplane entered an uncommanded left drift which he could not compensate for. The airplane departed the left side of the runway. Examination of the pressurized twin-turboprop airplane revealed structural damage to the lower portion of the nose section, as well as damage to the support structure for the nose landing gear assembly. All propeller blades were damaged upon ground contact. None of the 4 main tires were blown and the wheel brakes appeared to be functioning and in good condition. There was no fire. The 7 passengers and 2 crewmembers were able to egress the airplane normally and were not injured. The reason for the uncommanded nose wheel steering deflection could not be determined. A completed NTSB Form 6120.1/2 was not received from either the operator or the pilot. The weather was reported as calm winds, visibility 10 miles, clear skies, temperature 45 degrees Fahrenheit, dew point 28 degrees Fahrenheit, and a barometric pressure setting of 30.41 inches of Mercury. ## Aircraft - Registration: YV-2045 (not matched to a registry record) - Reported make and model: Fairchild Merlin SA-226-T - Category: Airplane - Serial number: TT-425 - Airframe hours: 3577 - Engines: Garrett-AiResearch TPE-331 1000 horsepower turbo prop - Damage: Substantial damage - Flight: Business, Part 91 - Registered owner: Unk - Airworthiness certificate: Standard, Transport - Departed: KFXE, Fort Lauderdale, FL - Destination: KRVS, Tulsa, OK - Flight plan: IFR - Airport: KRVS, Richard L.

NTSB leaves out names. - Pilot; injuries: none; airline transport; airplane ratings: multi-engine land, single-engine land; instrument ratings: airplane; medical: class 1; flight hours: 5,000 total, 1,500 in this make and model - Co-pilot; injuries: none ## Weather - Conditions: Visual (VMC), Day - Wind: calm - Visibility: 10 statute miles - Lowest ceiling: none - Temperature: 45 °F, dew point 28 °F - Altimeter: 30.40 inHg - Observed at: KRVS 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. Compare the reported make and model. --- OpenAirDocs.org is an independent research project of [Contrail Labs](https://contraillabs.com/). It is not affiliated with the FAA or the NTSB.
