# NTSB SEA07CA229: Quicksilver Manufacturing GT-500, N8058J, Newberg, OR, August 12, 2007 - Type: NTSB accident investigation - Classification: Accident · Serious injuries · Data collection · Final report - Date: August 12, 2007, 09:45 local (16:45 UTC) - Place: Newberg, OR - Coordinates: 45.295555, -122.955276 - Nearby events: https://openairdocs.org/map.md?lat=45.2956&lon=-122.9553&mi=10 - Phase of flight: [Maneuvering](https://openairdocs.org/ntsb-phases/450) (OpenAirDocs' grouping) - Highest injury: Serious injuries - Injuries: 1 serious - Status: Completed, report November 29, 2007 - Report: Approved by Office Director - NTSB case key (mKey): 66419 - NTSB case page: https://web.ntsb.gov/investigations/?ntsbnumber=SEA07CA229 - NTSB report (PDF, downloads): https://data.ntsb.gov/carol-repgen/api/Aviation/ReportMain/GenerateNewestReport/66419/pdf - Page: https://openairdocs.org/ntsb/SEA07CA229 ## Probable cause The pilot's failure to maintain airspeed while maneuvering, which resulted in an inadvertent stall and uncontrolled descent to terrain impact. A contributing factor was the pilot's lack of certification. ## Sequence of events In NTSB's coding before 2008 (https://www.ntsb.gov/GILS/Documents/codman.pdf). - Loss of control - in flight, maneuvering - airspeed - not maintained, pilot in command (cause) - lack of certification, pilot in command (contributing factor) - stall - inadvertent, pilot in command (cause) - In flight collision with terrain/water, descent - uncontrolled - terrain condition - ground ## Analysis During an interview conducted by FAA inspectors, the pilot reported that he stayed high in the pattern "because he was having engine problems and was afraid to land." He attempted several landings, but "decided to stay high and not land." During climb out after the third attempted landing, "the engine quit." The airplane stalled, rolled to the right and impacted the ground. The pilot did not possess a pilot's license, a student pilot certificate or a medical certificate. He had received 15 hours of flight instruction, some of which were in the accident airplane. He was not endorsed for solo flight. Witnesses reported that they observed the airplane make three approaches to runway 35. One witness reported that on the third approach, the airplane came across the threshold at an altitude of about 40 feet with a ground speed of about 20 to 25 mph. The airplane's wings were "wobbling back and forth," and the airplane was "yawing left and right." About midfield, the engine powered up, and the airplane entered a right turn. Another witness reported that he saw the airplane bank to the right, heard the engine power up, and then one second later, heard a "thud" as the airplane hit the ground. ## Factual narrative During an interview conducted by FAA inspectors, the pilot reported that he stayed high in the pattern "because he was having engine problems and was afraid to land."

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.
