Abstract:

The study compares accident causes with reported general aviation pilot habits during preflight activities. Calendar year 1968 accident data are compared with statistical data obtained from responses to a survey questionnaire sent to more than 3200 pilots. Charts were developed to show relationships between accident records and preflight procedures by operator category. One hundred eighty-four fatal general aviation accidents during 1968 could be linked to faulty preflight procedures. The largest number 81 of fatal accidents resulted from pilots proceeding under Visual Flight Rules into unfavorable weather conditions due to poor weather analysis and route planning. The next highest number 42 was caused by pilot impairment due to alcohol. Ninety-nine percent of the pilots report that they plan for more than a half hour fuel reserve for each flight however, the largest number of non-fatal preflight caused accidents 132 was due to fuel exhaustion. Of the preflight procedure caused accidents in 1968, 82 of the pilots had not filed flight plans of any type. Study results show that adherence to basic preflight procedures can reduce all general aviation accidents by as much as 14. Those basic procedures are disclosed. Author
