# NTSB DFW05CA211: Schleicher ASW-27b, N274DW, Encinal, TX, August 8, 2005 - Type: NTSB accident investigation - Classification: Accident · No injuries · Data collection · Final report - Date: August 8, 2005, 17:00 local (22:00 UTC) - Place: Encinal, TX - Coordinates: 27.857778, -99.096389 - Nearby events: https://openairdocs.org/map.md?lat=27.8578&lon=-99.0964&mi=10 - Phase of flight: [Maneuvering](https://openairdocs.org/ntsb-phases/450) (OpenAirDocs' grouping) - Highest injury: No injuries - Injuries: 1 uninjured - Status: Completed, report January 31, 2006 - Report: Approved by Office Director - Parties: San Antonio FSDO - NTSB case key (mKey): 62214 - NTSB case page: https://web.ntsb.gov/investigations/?ntsbnumber=DFW05CA211 - NTSB report (PDF, downloads): https://data.ntsb.gov/carol-repgen/api/Aviation/ReportMain/GenerateNewestReport/62214/pdf - Page: https://openairdocs.org/ntsb/DFW05CA211 ## Probable cause The pilot's misjudgment of distance and altitude during a cross-country soaring flight. A contributing factor was the lack of suitable terrain for the landing. ## Sequence of events In NTSB's coding before 2008 (https://www.ntsb.gov/GILS/Documents/codman.pdf). - In flight encounter with weather, maneuvering - weather condition - no thermal lift (contributing factor) - distance/altitude - misjudged, pilot in command (cause) - precautionary landing - attempted, pilot in command (contributing factor) - On ground/water collision with object, landing - roll - terrain condition - none suitable (contributing factor) - terrain condition - high vegetation - object - fence post ## Analysis The 5,635-hour commercial glider pilot encountered poor lift thermal conditions while attempting to fly a cross-country competition flight. The pilot lost lift and decided to turn towards an airfield. As the pilot approached the field it became clear that the airport had been abandoned and was unsuitable for landing. The pilot elected to land on a dirt road. As the glider was touching down a cactus caught the left wing, which turned the glider into a fence. The left wing then came into contact with a fence post and a 180-degree ground loop followed. ## Factual narrative On August 8, 2005, approximately 1700 central daylight time, a Schleicher ASW-27b glider, N274DW, sustained substantial damage during an off-airport landing on a road near Encinal, Texas. The commercial rated glider pilot, sole occupant of the glider, was not injured. Visual meteorological conditions prevailed and a flight plan was not filed for the 14 Code of Federal Regulations Part 91 personal flight. The flight originated at the Garner Field Airport (UVA), near Uvalde, Texas, approximately 1300, for a cross-country competition flight, with a minimum enroute time of 4 hours and 30 minutes. According to the 5,635-hour pilot, while attempting to fly to the Jim Hogg County Airport (HBV), near Hebbronville, Texas, he encountered poor thermal lift conditions and elected to return towards the A P Ranch Airport (TX27), near Encinal, Texas, which was the only airport within gliding distance. As the pilot approached the airfield, it became clear that the ranch airport had been abandoned and was unsuitable for landing. The pilot decided the best landing area was a nearby dirt road. As the glider was touching down, the left wing of the glider collided with a mature cactus, which then turned the glider into a fence. The left wing came into contact with a fence post and a 180-degree ground loop followed. Photos provided by the pilot, revealed structural damage to the glider when the fuselage broke aft of the cockpit. Additional damage was observed on the control surfaces of the right wing. At 1656, the automated surface observing system (ASOS) at Laredo International Airport (LRD), near Laredo, Texas, located approximately 28 nautical miles southwest of the accident site, reported winds from 150 degrees at 10 knots, 10 statute miles visibility, a clear sky, temperature 100 degrees Fahrenheit, dew point 66 degrees Fahrenheit, and a barometric pressure setting of 29.87 inches of Mercury. ## Aircraft - Registration: N274DW (not matched to a registry record) - Reported make and model: Schleicher ASW-27b - Category: Glider - Serial number: 27189 - Damage: Substantial damage - Flight: Personal, Part 91 - Operator: David Weaver - Registered owner: David Weaver - Airworthiness certificate: Standard, Utility - Departed: UVA, Uvalde, TX - Destination: UVA, Uvalde, TX - Airport: TX27, AP Ranch Airport, runway 14, 3,700 × 50 ft, gravel ## Flight crew As NTSB recorded them.

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.
