# NTSB DFW08CA008: Cub Crafters CC11-100, N954Z, Laurel, MS, October 6, 2007 - Type: NTSB accident investigation - Classification: Accident · No injuries · Data collection · Final report - Date: October 6, 2007, 15:30 local (20:30 UTC) - Place: Laurel, MS - Coordinates: 31.170278, -89.169998 - Nearby events: https://openairdocs.org/map.md?lat=31.1703&lon=-89.1700&mi=10 - Phase of flight: [Taxi](https://openairdocs.org/ntsb-phases/250) (OpenAirDocs' grouping) - Highest injury: No injuries - Injuries: 1 uninjured - Status: Completed, report December 20, 2007 - Report: Approved by Office Director - Parties: Jackson, Mississippi - NTSB case key (mKey): 66900 - NTSB case page: https://web.ntsb.gov/investigations/?ntsbnumber=DFW08CA008 - NTSB report (PDF, downloads): https://data.ntsb.gov/carol-repgen/api/Aviation/ReportMain/GenerateNewestReport/66900/pdf - Page: https://openairdocs.org/ntsb/DFW08CA008 ## Probable cause The single-engine pilot's failure to avoid the jet blast while taxiing and the maintenance personnel's poor judgment to perform the engine ground run with the jet's engine exhaust directed across the taxiway. ## Sequence of events In NTSB's coding before 2008 (https://www.ntsb.gov/GILS/Documents/codman.pdf). - Propeller blast or jet exhaust/suction, taxi - propeller/jet blast encounter - encountered, pilot in command (cause) - judgment - poor, company maintenance personnel (cause) - Loss of control - on ground/water, taxi - terrain condition - ground ## Analysis The 3,500-hour commercial pilot, who was exercising sport pilot privileges, lost control of the tailwheel-equipped airplane upon encountering the jet blast from a twin-turbofan powered corporate jet. The airplane was taxiing to the ramp upon completion of a local flight when the mishap occurred. The corporate jet was being run-up by maintenance personnel with the jet engine blast directed across the taxiway. The single-engine airplane came to rest in an upright position and the pilot and passenger were able to exit the airplane unassisted. The left wing spar was found to have received structural damage. The airport did not have an operating control tower. According to the Aeronautical Information Manual, Chapter 7, paragraph 7-3-8 a, "....the flight disciplines necessary to ensure vortex avoidance during VFR operations must be exercised by the pilot." In addition, paragraph 7-3-1 states that "pilots of larger aircraft should be particularly careful to consider the effects of their "jet blast" on other aircraft....during ground operations." ## Factual narrative The 3,500-hour commercial pilot, who was exercising sport pilot privileges, lost control of the tailwheel-equipped airplane upon encountering the jet blast from a twin-turbofan powered corporate jet.

(-23) Aircraft N954Z taxied behind a Learjet N631SF during a maintenance run. N954Z was blown around bending right wing spar. From the NTSB's public API. 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. Compare the reported make and model. --- OpenAirDocs.org is an independent research project of [Contrail Labs](https://contraillabs.com/). It is not affiliated with the FAA or the NTSB.
