Aviation safety reports, made easier to study

NTSB Reports is an independent research and search tool for public aviation accident and incident records. It brings NTSB aviation reports, structured fields, docket files, extracted figures, photos, videos, and update history into one searchable interface.

The goal is practical safety education: make it faster to find relevant investigations, compare similar events, review factual records, and understand the evidence behind probable-cause and preliminary reports.

The investigative work and source records belong to the National Transportation Safety Board and the published investigation record. This site is not affiliated with or endorsed by the NTSB.

The 1,070-hour pilot reported that during takeoff on Runway 9 (a 5,000-foot long and 100-foot wide asphalt runway) the airplane became airborne, settled back onto the runway, exited the runway, before impacting a culvert at an intersecting taxiway. The pilot added that as the airplane became airborne, the "takeoff pitch was too steep" and he could not keep the airplane straight with rudder. The pilot reported that at the time of the accident, the wind was from the southeast at 15 knots.

NTSB Probable Cause

The pilot's premature lift-off before attaining adequate airspeed resulting in a stall and collision with the ground.

Full Narrative

On August 27, 2004, approximately 1530 central daylight time, an amateur-built Lancair 320 single-engine airplane, N30KR, registered and operated by a private individual, sustained substantial damage when it impacted terrain following a loss of control during takeoff from the Houston Southwest Airport (AXH) near Houston, Texas. The commercial pilot and his passenger were not injured. Visual meteorological conditions prevailed, and a flight plan was not filed for the 14 Code of Federal Regulations Part 91 personal flight. The cross-country flight was destined for the Southeast Texas Regional Airport near Beaumont, Texas. The 1,070-hour pilot reported in the Pilot/Operator Aircraft Accident Report (NTSB Form 6120.1/2) that during takeoff from Runway 9 (a 5,000-foot long and 100-foot wide asphalt runway) the airplane became airborne at an airspeed of approximately 90 knots. The pilot added that when the airplane was approximately 3 feet above the ground, the "takeoff pitch was too steep," and the airplane settled back onto the runway drifting left of the runway centerline. Subsequently, the airplane exited the left side of the runway and impacted a culvert at an intersecting taxiway before coming to rest in an upright position. Examination of the airplane by the Federal Aviation Administration (FAA) inspector, who responded to the site of the accident, revealed that the nose wheel was folded under the engine. Both wings and the bottom side of the fuselage sustained structural damage. The engine firewall was also bent. At 1453, the automated weather observing system at the Sugar Land Regional Airport, located approximately 11 nautical miles northwest of AXH, reported wind from 140 degrees at 9 knots, visibility 10 statute mile, scattered clouds at 4,400, temperature 91 degrees Fahrenheit, dew point 77 degrees Fahrenheit, and an altimeter setting of 29.97 inches of Mercury. The pilot reported that at the time of the accident, the wind was from the southeast at 15 knots.
