A TWO WAY CONTROLLED SAMPLE FOR COLLECTING TANKER AIRCRAFT BASE MAINTENANCE INFORMATION,
Abstract
The document contains a description from the statistical viewpoint of the sampling design, selection of estimators, and preliminary analysis of maintenance data on KC-135 tanker aircraft of the Strategic Air Command. The aim was to study the effect of aircraft aging on maintenance needs, the relationships between man-hours and other maintenance costs, and sources of error in recording materials consumed. Thirty-three aircraft were selected by a two-stage process so that the sample was stratified by airbase and controlled by age group, while giving all aircraft approximately equal selection probabilities.
