What is the most frequent causal factor in general aviation accidents involving the pilot-in-command?

7-6-1. Accident Causal Factors
a. The 10 most frequent causal factors for general aviation accidents that involve the pilot-in-command are:
1. Inadequate preflight preparation and/or planning.
2. Failure to obtain and/or maintain flying speed.
3. Failure to maintain direction control.
4. Improper level off.
5. Failure to see and avoid objects or obstructions.
6. Mismanagement of fuel.
7. Improper inflight decisions or planning.
8. Misjudgment of distance and speed.
9. Selection of unsuitable terrain.
10. Improper operation of flight controls.
b. This list remains relatively stable and points out the need for continued refresher training to establish a
higher level of flight proficiency for all pilots. A part of the FAA's continuing effort to promote increased aviation
safety is the Aviation Safety Program. For information on Aviation Safety Program activities contact your nearest
Flight Standards District Office.
c. Alertness. Be alert at all times, especially when the weather is good. Most pilots pay attention to business
when they are operating in full IFR weather conditions, but strangely, air collisions almost invariably have
occurred under ideal weather conditions. Unlimited visibility appears to encourage a sense of security which is
not at all justified. Considerable information of value may be obtained by listening to advisories being issued
in the terminal area, even though controller workload may prevent a pilot from obtaining individual service.
d. Giving Way. If you think another aircraft is too close to you, give way instead of waiting for the other pilot
to respect the right-of-way to which you may be entitled. It is a lot safer to pursue the right-of-way angle after
you have completed your flight.
