2008 Nall Report - Aircraft Owners and Pilots Association

ACCIDENT FACTORS: HIGH-RISK PHASES OF FLIGHT
accounted for 46, three of them fatal; multiengine
aircraft for 25, with two fatal; and single-engine
seaplanes for four.
Aircraft Involved in Landing Accidents
All Accidents Fatal Accidents
Single-engine fixed* 352 (83.2%) 3 (37.5%)
Conventional gear 132 0
SE retractable 46 (10.9%) 3 (37.5%)
Multiengine 25 (5.9%) 2 (25.0%)
*Includes four seaplanes.
Type of Operation
Personal flights accounted for about the same
proportion of landing accidents (294 of 423, or
69.5 percent) as of other types of GA accidents
(Figure 38). These included seven of the eight fatal
accidents. Instructional flying, however, counted
for almost all the rest (92, or 21.7 percent), none
of them fatal. The remaining crashes were about
evenly split between business travel (15) and an assortment
of different types of working flights (13).

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