# NTSB ATL00LA070: Leslie Briggs Glasair III, N422CS, Smithfield, NC, July 30, 2000 - Type: NTSB accident investigation - Classification: Accident · Fatal · Limited investigation · Final report - Date: July 30, 2000, 13:55 local (18:55 UTC) - Place: Smithfield, NC - Coordinates: 35.499095, -78.339988 (estimated) - Nearby events: https://openairdocs.org/map.md?lat=35.4991&lon=-78.3400&mi=10 - Phase of flight: [Landing](https://openairdocs.org/ntsb-phases/550) (OpenAirDocs' grouping) - Highest injury: Fatal - Injuries: 2 fatal - Status: Completed, report March 2, 2001 - Report: Approved by Office Director - NTSB case key (mKey): 49836 - NTSB case page: https://web.ntsb.gov/investigations/?ntsbnumber=ATL00LA070 - NTSB report (PDF, downloads): https://data.ntsb.gov/carol-repgen/api/Aviation/ReportMain/GenerateNewestReport/49836/pdf - Page: https://openairdocs.org/ntsb/ATL00LA070 ## Probable cause The pilot's failure to maintain flying speed during an emergency landing which lead to an inadvertent stall/spin. A factor was the pilot's failure to secure the cockpit canopy prior to takeoff. ## Sequence of events In NTSB's coding before 2008 (https://www.ntsb.gov/GILS/Documents/codman.pdf). - Loss of control - in flight, emergency landing after takeoff - window,canopy - not secured (contributing factor) - aircraft control - not maintained, pilot in command (cause) - stall/spin - inadvertent, pilot in command (cause) - In flight collision with terrain/water, descent - uncontrolled ## Analysis A witness flying in the vicinity of the airport stated that the airplane took off from runway 03 and climbed to about 500 feet above ground level. He said the airplane turned sharply to the left and then to the right and headed back towards the runway, then rolled inverted and collided with the runway surface in a 20 to 30 degree nose down attitude. The airport manager stated that he noticed that the cockpit canopy was unlatched during the takeoff roll. He then contacted the pilot by radio. The pilot responded, but his transmission was unreadable. The aircraft made a left turn back to the runway. While making the final turn to align with runway 21 the airplane rolled to the right in a steep decent and impacted the runway. ## Factual narrative On July 30, 2000, about 1355 central daylight time, a Leslie Briggs Glasair III, N422CS, collided with the terrain after takeoff from the airport at Smithfield, North Carolina.

A witness flying in the vicinity of the airport stated that the airplane took off from runway 03 and climbed to about 500 feet above ground level. He said the airplane turned sharply to the left and then to the right and headed back towards the runway, then rolled inverted and collided with the runway surface in a 20 to 30 degree nose down attitude. The airport manager stated that he noticed that the cockpit canopy was unlatched during the takeoff roll. He then contacted the pilot by radio. The pilot responded, but his transmission was unreadable. The aircraft made a left turn back to the runway.
