# NTSB NYC03CA188: Lancair IVP, N789HS, Manassas, VA, September 2, 2003 - Type: NTSB accident investigation - Classification: Accident · No injuries · Data collection · Final report - Date: September 2, 2003, 10:40 local (14:40 UTC) - Place: Manassas, VA - Coordinates: 38.721389, -77.515556 - Nearby events: https://openairdocs.org/map.md?lat=38.7214&lon=-77.5156&mi=10 - Phase of flight: [Takeoff](https://openairdocs.org/ntsb-phases/300) (OpenAirDocs' grouping) - Highest injury: No injuries - Injuries: 2 uninjured - Status: Completed, report January 24, 2005 - Report: Approved by Office Director - NTSB case key (mKey): 57843 - NTSB case page: https://web.ntsb.gov/investigations/?ntsbnumber=NYC03CA188 - NTSB report (PDF, downloads): https://data.ntsb.gov/carol-repgen/api/Aviation/ReportMain/GenerateNewestReport/57843/pdf - Page: https://openairdocs.org/ntsb/NYC03CA188 ## Probable cause The pilot's failure to follow the published takeoff procedures for the make and model airplane and his failure to maintain directional control during takeoff. ## Sequence of events In NTSB's coding before 2008 (https://www.ntsb.gov/GILS/Documents/codman.pdf). - Loss of control - on ground/water, takeoff - roll/run - procedures/directives - not followed, pilot in command (cause) - directional control - not maintained, pilot in command (cause) - On ground/water collision with object, takeoff - roll/run - object - sign ## Analysis Prior to the flight, the pilot received an IFR clearance with changes to the route on his flight plan. Subsequently, the pilot felt rushed and distracted during the pre-takeoff checklist, and forgot to extend the flaps to the takeoff position. During the takeoff roll, the airplane initially became airborne, but settled back on the runway. It then traveled off the right side of the runway, struck a runway sign, and came to rest in a grass area. ## Factual narrative On September 2, 2003, about 1040 eastern daylight time, an amateur built Lancair IVP, N789HS, was substantially damaged during takeoff from Manassas Regional Airport (HEF), Manassas, Virginia. The certificated private pilot and passenger were not injured. Visual meteorological conditions prevailed for the planned flight to Destin-Fort Walton Beach Airport (DTS), Destin, Florida. An instrument flight rules (IFR) flight plan was filed for the personal flight conducted under 14 CFR Part 91. The pilot stated that prior to the flight, he received an IFR clearance with complex changes to the route on his flight plan. Subsequently, the pilot felt rushed and distracted during the pre-takeoff checklist, and forgot to extend the flaps to the takeoff position. He initiated a takeoff on runway 16R, a 3,702-foot long, 100-foot wide, asphalt runway. During the takeoff roll, the airplane initially became airborne, but settled back on the runway. It then traveled off the right side of the runway, struck a runway sign, and came to rest in a grass area. Examination of the airplane by a Federal Aviation Administration inspector revealed that the left main landing gear collapsed, the nose gear sheared off, and both wings sustained substantial damage. The inspector noted that the airplane departed off the right side of the runway about 1,800 feet from the start of the takeoff roll. The reported winds at the accident site, at 1055, were from 140 degrees at 5 knots. ## Aircraft - Registration: [N789HS](https://openairdocs.org/deregistered/N789HS-2007-01-23), registration cancelled 2007-01-23, S/N LIV294, built 2002 (OpenAirDocs) - Reported make and model: Lancair IVP - Registry model: [Smith Hugh H LANCAIR IVP](https://openairdocs.org/model/smith-hugh-h-lancair-ivp) (registry code 05602DV) (OpenAirDocs) - Registry engine: [Continental IO-550 series](https://openairdocs.org/engine/continental-io-550-series) (registry code 17042, reciprocating) (OpenAirDocs) - Category: Airplane, amateur-built - Serial number: LIV294 - Engines: Continental TSIO-550 350 horsepower reciprocating - Damage: Substantial damage - Flight: Personal, Part 91 - Registered owner: Hugh H.
