# NTSB FTW98LA355: Crane Quicksilver Sport 2, N4562G, Glenn Heights, TX, August 8, 1998 - Type: NTSB accident investigation - Classification: Accident · No injuries · Limited investigation · Final report - Date: August 8, 1998, 18:00 local (23:00 UTC) - Place: Glenn Heights, TX - Coordinates: 32.51044, -96.799484 (estimated) - Nearby events: https://openairdocs.org/map.md?lat=32.5104&lon=-96.7995&mi=10 - Phase of flight: [Maneuvering](https://openairdocs.org/ntsb-phases/450) (OpenAirDocs' grouping) - Highest injury: No injuries - Injuries: 1 uninjured - Status: Completed, report February 16, 2001 - Report: Approved by Office Director - NTSB case key (mKey): 43674 - NTSB case page: https://web.ntsb.gov/investigations/?ntsbnumber=FTW98LA355 - NTSB report (PDF, downloads): https://data.ntsb.gov/carol-repgen/api/Aviation/ReportMain/GenerateNewestReport/43674/pdf - Page: https://openairdocs.org/ntsb/FTW98LA355 ## Probable cause The loss of engine power as the result of the owner/pilot's failure to install and adjust the proper carburetor jets. A factor was the lack of suitable terrain for the forced landing. ## Sequence of events In NTSB's coding before 2008 (https://www.ntsb.gov/GILS/Documents/codman.pdf). - Loss of engine power, maneuvering - maintenance,adjustment - not performed, owner/pilot mechanic (cause) - Forced landing, emergency descent/landing - terrain condition - none suitable (contributing factor) ## Analysis The pilot reported that, after takeoff, about 1 mile from the airstrip the Rotax engine began to run rough. He immediately turned back toward the airstrip. About 1/2 mile from the airstrip, the engine lost power, and the pilot maneuvered the aircraft into a field. During the landing, the vertical main spars (wing support tubes) were structurally damaged. After the accident, the pilot stated that he believed that the engine problem was precipitated by his not replacing the carburetor jets. He stated that the installed jets were more suitable for 'higher' altitude operations. The aircraft had recently been transported from Colorado. ## Factual narrative On August 8, 1998, approximately 1800 central daylight time, a Crane Quicksilver Sport 2 registered ultralight, N4562G, was substantially damaged during a forced landing following a loss of engine power, near Glenn Heights, Texas. The non-certificated pilot, who was the only occupant, was not injured. Visual meteorological conditions prevailed, and no flight plan was filed for the Title 14 CFR Part 91 personal flight. The local flight originated from a private grass airstrip about 5 minutes prior to the accident. The aircraft "type" classification is an "ultralight", however, since it has a registration number and an airworthiness certificate, it does not meet the guidelines for an ultralight exemption under Title 14 CFR Part 103, and therefore, must comply with FAA regulations regarding homebuilt "airplanes." The pilot reported that, after takeoff, about 1 mile from the airstrip, the 65 horsepower Rotax engine began to run rough. He immediately turned back toward the airstrip. About 1/2 mile from the airstrip, the engine lost power, and the pilot maneuvered the aircraft into a field. During the landing, the vertical main spars (wing support tubes) were structurally damaged. The pilot stated that he believed that the engine problem was precipitated by his not replacing/adjusting the carburetor jets. He stated that the installed jets were more suitable for "higher" altitude operations. The aircraft, which had accumulated a total of 12 flight hours, had recently been transported from Colorado. ## Aircraft - Registration: [N4562G](https://openairdocs.org/deregistered/N4562G-2017-05-31), registration cancelled 2017-05-31, S/N 635, built 1995 (OpenAirDocs) - Reported make and model: Crane QUICKSILVER SPORT 2 (QUICKSILVE) - Registry model: [Crane Ronald F QCKSLVR SPRT MXL II](https://openairdocs.org/model/crane-ronald-f-qckslvr-sprt-mxl-ii) (registry code 05630CY) (OpenAirDocs) - Registry engine: [Bombardier ROTAX (ALL)](https://openairdocs.org/engine/bombardier-rotax-all) (registry code 09050, reciprocating) (OpenAirDocs) - Category: Airplane, amateur-built - Serial number: 635 - Airframe hours: 12 - Engines: Rotax 582 reciprocating - Damage: Substantial damage - Flight: Personal, Part 91 - Registered owner: Ronald F.

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.
