# NTSB ATL93LA067: Burkhart Grob G102, N792G, Kingston, GA, April 1, 1993 - Type: NTSB accident investigation - Classification: Accident · Minor injuries · Limited investigation · Final report - Date: April 1, 1993, 13:30 local (18:30 UTC) - Place: Kingston, GA - Coordinates: 34.229408, -84.940017 (estimated) - Nearby events: https://openairdocs.org/map.md?lat=34.2294&lon=-84.9400&mi=10 - Phase of flight: [Maneuvering](https://openairdocs.org/ntsb-phases/450) (OpenAirDocs' grouping) - Highest injury: Minor injuries - Injuries: 1 minor - Status: Completed, report September 26, 1994 - Report: Approved by Office Director - NTSB case key (mKey): 3197 - NTSB case page: https://web.ntsb.gov/investigations/?ntsbnumber=ATL93LA067 - NTSB report (PDF, downloads): https://data.ntsb.gov/carol-repgen/api/Aviation/ReportMain/GenerateNewestReport/3197/pdf - Page: https://openairdocs.org/ntsb/ATL93LA067 ## Probable cause The pilot's attempted return to the departure runway that resulted in a stall at an altutude that was too low to permit recovery. ## Sequence of events In NTSB's coding before 2008 (https://www.ntsb.gov/GILS/Documents/codman.pdf). - Loss of control - in flight, maneuvering - turn to landing area (emergency) - emergency procedure - improper, pilot in command (cause) - airspeed(vs) - not maintained, pilot in command (cause) - stall - inadvertent, pilot in command (cause) - In flight collision with terrain/water, descent - uncontrolled ## Analysis DURING A TOWED TAKE OFF, THE TOW PLANE LOST ENGINE POWER AND THE TOW PILOT RELEASED THE GLIDER. THE GLIDER PILOT ALSO RELEASED THE TOW LINE, THEN BEGAN A LEFT TURN TO PROVIDE ENOUGH ROOM TO MAKE A RIGHT TURN BACK TO THE RUNWAY. HE STATED THAT, DURING THE RIGHT TURN BACK TO THE RUNWAY, THE NOSE FELL AND THE GLIDER IMPACTED THE GROUND. ## Factual narrative On April 1, 1993, at about 1330 eastern standard time, a Grob 102, N792G, collided with the ground during a forced landing at Kingston, Georgia. The glider was registered to and operated by Atlanta Soaring Club, Inc. under 14 CFR Part 91, and visual flight rules. Visual meteorological conditions prevailed. A flight plan was not filed for the personal flight. There were minor injuries to the private pilot, while the glider was substantially damaged. The flight was originating at the time. During a towed take off, the tow plane's engine lost power. The tow pilot released the glider at about 150 feet above the ground. The glider pilot stated that he released the tow rope, then turned left to provide room to make a right turn back to the runway. According to the glider pilot, during the right turn the "nose fell & I hit the ground." The tow pilot's diagram of the airstrip depicted an open field to the east of the runway. He stated that it was his planned emergency landing site when the engine lost power. Subsequently, the tow pilot discovered that the fuel shut-off valve had been partially closed. The position of the fuel shut- off valve resulted in a loss of power until the throttle was reduced. ## Aircraft - Registration: [N792G](https://openairdocs.org/deregistered/N792G-1994-01-10), registration cancelled 1994-01-10, S/N 5629CB (OpenAirDocs) - Reported make and model: Burkhart Grob G102 - Registry model: [Burkhart Grob Flugzeugbau G102 CLUB ASTIR IIIB](https://openairdocs.org/model/burkhart-grob-flugzeugbau-g102-club-astir-iiib) (registry code 1660106) (OpenAirDocs) - Category: Glider - Serial number: 5629 - Airframe hours: 1208 - Engines: unknown - Damage: Substantial damage - Flight: Personal, Part 91 - Registered owner: Atlanta Soaring Club - Airworthiness certificate: Standard, Normal - Last inspection: Annual, December 1, 1992, 21 hours before - Departed: ETO - Destination: ETO - Airport: ETO, Etowah Bend, runway 18, 3,800 × 100 ft, grass/turf ## Flight crew As NTSB recorded them.
