An analysis of U. S. Navy major aircraft accidents during the period Fiscal Year 1972-1974 was conducted. Forward (stepwise) Multiple Regression techniques were employed on a group of ten basic variables considered time dependent. The multiple regression techniques were employed to develop predictive equations for the dependent variable, Accident Rate with a view to determining which of the basic variable measures were significant in accident rate studies and if the variables are unique to a specific aircraft community or generally applicable to all aircraft. Aircraft considered independently were A-4, A-6, A-7, and F-4, additionally composites of Attack aircraft (A-3, A-4, A-5, A-6, A-7), Fighter Aircraft (F-4 and F-8), Propeller aircraft (E-1, E-2, C-1, C-2, S-2, P-3, C-117, C-118, and C-130) and Helicopters (H-1 H-2, H-3, H-46, and H-53) were considered.
