# NTSB ATL98LA085: Stroud SKY Bolt, N2951S, Mocksville, NC, June 23, 1998 - Type: NTSB accident investigation - Classification: Accident · No injuries · Limited investigation · Final report - Date: June 23, 1998, 12:30 local (16:30 UTC) - Place: Mocksville, NC - Coordinates: 35.930881, -80.399612 (estimated) - Nearby events: https://openairdocs.org/map.md?lat=35.9309&lon=-80.3996&mi=10 - Phase of flight: [Landing](https://openairdocs.org/ntsb-phases/550) (OpenAirDocs' grouping) - Highest injury: No injuries - Injuries: 2 uninjured - Status: Completed, report May 19, 1999 - Report: Approved by Office Director - NTSB case key (mKey): 4000 - NTSB case page: https://web.ntsb.gov/investigations/?ntsbnumber=ATL98LA085 - NTSB report (PDF, downloads): https://data.ntsb.gov/carol-repgen/api/Aviation/ReportMain/GenerateNewestReport/4000/pdf - Page: https://openairdocs.org/ntsb/ATL98LA085 ## Probable cause The pilot's loss of directional control during landing roll when the front seat occupant inadvertently got his foot 'jammed' between the strut bungee and the rudder/brake peddle. A factor was the inadequate design of the rudder/brake peddle system. ## Sequence of events In NTSB's coding before 2008 (https://www.ntsb.gov/GILS/Documents/codman.pdf). - Loss of control - on ground/water, landing - flare/touchdown - flight control,rudder - movement restricted (cause) - aircraft control - restricted, passenger (cause) - acft/equip,inadequate design, kit manufacturer (contributing factor) - Nose over, landing - roll ## Analysis According to the FAA, during landing on runway 09, the aircraft veered off the right side of the runway and nosed over. The inspector found a 300 foot skid mark made by the left main landing gear, and a 150 foot skid mark, made by the right main landing gear. The aircraft received substantial damage to the propeller, rudder, and left wing. On the landing roll, the pilot applied rudder to get the airplane onto the runway centerline, the foot of the occupant in the front seat was pressed onto the opposite brake peddle causing the airplane to react slowly. The harder the pilot applied the rudder, the harder the opposite brake was actuated. As the airplane started to depart the runway, the pilot said he applied left brake. Inertia caused the airplane to nose over. The pilot shut the airplane down and he and the passenger egressed from the inverted airplane. ## Factual narrative On June 23,1998, about 1230 eastern daylight time, a Stroud Sky Bolt, experimental airplane, N2951C, veered off the right side of the runway and nosed over while landing at Twin Lakes airport in Mocksville North Carolina. The local flight was operating under the provisions of Title 14 CFR Part 91, and visual flight rules. Visual meteorological conditions prevailed and no flight plan was filed. There were no injuries to the pilot or passenger, and the aircraft received substantial damage. The flight originated about 1150 EDT. According to the FAA, during landing on runway 09, the aircraft veered off the right side of the runway and flipped over. The inspector found a 300 foot skid mark made by the left main landing gear, and a 150 foot skid mark, made by the right main landing gear. The aircraft received substantial damage to the propeller, vertical stabilizer, rudder, and left wing. During the investigation, the FAA investigator found that when the occupant of the front seat put his feet in front of the landing gear strut bungee, and the person in the back seat (usually the person flying) applied left or right rudder, the front occupant's foot became jammed between the landing gear strut bungee attachment point and the rudder/brake peddle. This prompted inadvertent, full braking on the side opposite that of the applied rudder. According to the pilot, he applied right rudder to get the airplane onto the runway centerline, after he touched down to the left of center, the foot of the occupant in the front seat was pressed onto the opposite brake peddle causing the airplane to react slowly. As the airplane crossed the centerline the pilot applied left rudder to follow the track of the centerline. This had no effect, due to the inadvertent force being applied to the right rudder/brake pedal by the passenger, and the airplane continued off the right side of the runway. The harder the pilot applied the rudder, the harder the opposite brake was actuated. As the airplane started to depart the runway, the pilot said he applied left brake in a final attempt to steer the aircraft back onto the runway. Inertia caused the airplane to nose over. The pilot shut the airplane down and he and the passenger egressed from the inverted airplane. ## Aircraft - Registration: [N2951S](https://openairdocs.org/deregistered/N2951S-2005-07-11), registration cancelled 2005-07-11, S/N 001, built 1995 (OpenAirDocs) - Reported make and model: Stroud SKY BOLT - Registry model: [Stroud Danny SKYBOLT](https://openairdocs.org/model/stroud-danny-skybolt) (registry code 05626XB) (OpenAirDocs) - Registry engine: [Lycoming 0-540 series](https://openairdocs.org/engine/lycoming-0-540-series) (registry code 41532, reciprocating) (OpenAirDocs) - Category: Airplane, amateur-built - Serial number: 001 - Airframe hours: 52 - Engines: Lycoming IO540-B4B5 260 horsepower reciprocating - Damage: Substantial damage - Flight: Personal, Part 91 - Operator: Joe E Mcglothlin - Registered owner: Danny C.

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.
