The Analysis of National Transportation Safety Broad Small Single-Engine Fixed-Wing Aircraft Accident/Incident Reports for the Potential Presence of Low-Level Wind Shear.
Abstract
The National Transportation Safety Board aircraft accident/incident data base covering the years 1964 through 1975 was screened to select those accidents involving single-engine aircraft of less than 12,500 pounds gross weight in which the potential of low-level wind shear as a factor could not be discounted. The software filtering resulted in identifying 2,469 small single-engine aircraft accident briefs which met the criteria for the possible presence of wind shear. A review of these briefs for the years 1964 through 1973 (excluding 1970, 1971, 1974, and 1975) further reduced this number to 304, which comprised the final data base used in this analysis. The presence of a low-level wind shear was a distinct possibility in 71 of these takeoff, approach, or landing accidents. Of this number, 48 involved mechanically (orographic or topographic) induced shears. In 23 of the cases, thunderstorms were reported or obsrved close to the aircraft flightpath. (Author)
