ACCIDENT FACTORS: HIGH-RISK PHASES OF FLIGHT<br />

aircraft for 25, with two fatal; <strong>and</strong> single-engine<br />
seaplanes for four.<br />
<strong>Aircraft</strong> Involved in L<strong>and</strong>ing Accidents<br />

Type of Operation<br />
Personal flights accounted for about the same<br />
proportion of l<strong>and</strong>ing accidents (294 of 423, or<br />
69.5 percent) as of other types of GA accidents<br />
(Figure 38). These included seven of the eight fatal<br />
accidents. Instructional flying, however, counted<br />
for almost all the rest (92, or 21.7 percent), none<br />
of them fatal. The remaining crashes were about<br />
evenly split between business travel (15) <strong>and</strong> an assortment<br />
of different types of working flights (13).<br />

Only three l<strong>and</strong>ing accidents occurred in IMC, <strong>and</strong><br />
all but 31 (7.3 percent) occurred during daylight<br />
hours (Figure 39).<br />
Accident Case Study<br />
MIA08LA024<br />
Cirrus SR-22, Hendersonville, North Carolina<br />
Two uninjured<br />
History of Flight<br />
The pilot stated that he l<strong>and</strong>ed on runway 15 <strong>and</strong> was on the<br />
l<strong>and</strong>ing rollout when a gust of wind caused the left wing to<br />
come up. He applied left aileron <strong>and</strong> there was no response.<br />
The airplane started turning to the right. He lost directional<br />
control of the airplane <strong>and</strong> it came to a stop on the runway.<br />
A witness stated that he heard an increase in engine power<br />
<strong>and</strong> looked up. The airplane was about 2 feet above the runway<br />
“flailing,” rose to an altitude of less than ten feet, <strong>and</strong><br />
appeared to be banking <strong>and</strong> yawing out of control. Runway<br />
15 was 3075 x 40 feet.<br />
Pilot Information<br />
The instrument-rated private pilot, age 52, had 985 hours<br />
total flight time with 101 hours in type. He had logged 24<br />
hours in the previous 90 days <strong>and</strong> 11 in the preceding 30, all<br />
in the accident make <strong>and</strong> model.<br />
Weather<br />
The nearest weather reporting facility, located 11 nautical<br />
miles southeast of the crash site, reported clear sky conditions<br />
<strong>and</strong> winds from 150 degrees at 8 knots. No gusting<br />
winds were reported at the time of the accident.<br />
Probable Cause<br />
The pilot’s improper recovery from a bounced l<strong>and</strong>ing resulting<br />
in a loss of directional control.<br />
ASF Comments<br />
Proper execution of go-arounds <strong>and</strong> balked l<strong>and</strong>ings should<br />
be part of checkouts <strong>and</strong> a comprehensive recurrent training<br />
program. It’s not something we practice often <strong>and</strong> yet is a<br />
dem<strong>and</strong>ing maneuver.<br />
