Maneuvering accidents, which accounted for one
out of five (20.2 percent) of all fatal GA accidents,
showed an increase to 91 from the 85 posted
the year before. Some of these accidents involve
questionable 80 pilot judgment, such as decisions to
engage in buzzing, low passes, or other high-risk
activities, while others are attributed to deficiencies
70 in basic airmanship. The trend in maneuver-

percentage of either total or fatal maneuvering
accidents since 1998.

Takeoff and climb accident statistics continue to
show gradual improvement in both total and fatal
crashes (Figure 11). Loss of directional control is a
frequent causal factor in these accidents.
