Preliminary Report
On August 10, 1996 about 1515 eastern daylight time, N5067C, a Bellanca 7ECA,
a personal flight, had a loss of control during landing on runway 29 at
Hanscom Field Airport, Bedford, Massachusetts. Visual meteorological
conditions existed. The certificated private pilot and passenger were not
injured. The aircraft was substantially damaged. The local flight was
conducted under 14 CFR Part 91. The airplane went off the side of the runway
during the landing followed by collapse of the right main gear. The pilot
reported: "We came over the numbers at 80 mph indicated airspeed, and I
flared the aircraft and we made a wheel landing, touching down at
approximately 65 mph indicated airspeed. Everything was fine at first and
then the aircraft veered to the right, into the wind. "I corrected with left
rudder pedal, and as I did, the tail wheel settled onto the runway. The
aircraft made an abrupt turn to the left, and I realized we were in a ground
loop. I added a little power, got the tail wheel off the ground, and
recovered from the ground loop, but we were heading off the left side of the
runway, approximately 85 to 90 degrees from runway heading. I had regained
control of the aircraft, but we didn't have enough room to maneuver back onto
the runway. I closed the throttle and started braking the aircraft. When we
departed the runway, I leaned the mixture, and continued braking. Everything
was fine until we hit a bump, and the aircraft jerked violently to the left,
resting on the right side."
Probable Cause Report
The airplane went off the side of the runway during the landing, followed by
collapse of the right main gear. The pilot reported: "We came over the
numbers at 80 mph indicated airspeed, and I flared the aircraft and we made a
wheel landing, touching down at approximately 65 mph indicated airspeed.
Everything was fine at first and then the aircraft veered to the right, into
the wind. "I corrected with left rudder pedal, and as I did, the tail wheel
settled onto the runway. The aircraft made an abrupt turn to the left, and I
realized we were in a ground loop. I added a little power, got the tail wheel
off the ground, and recovered from the ground loop, but we were heading off
the left side of the runway, approximately 85 to 90 degrees from runway
heading. I had regained control of the aircraft, but we didn't have enough
room to maneuver back onto the runway. I closed the throttle and started
braking the aircraft. When we departed the runway, I leaned the mixture, and
continued braking. Everything was fine until we hit a bump, and the aircraft
jerked violently to the left, resting on the right side." The pilot reported
no mechanical malfunction. He stated the accident could have been prevented
if he had "additional training in crosswind landings for tail dragger
aircraft."
Probable Cause
The pilot's inadequate compensation for wind conditions, and his failure to
maintain directional control, which resulted in a ground loop/swerve. The
variable wind condition was a related factor.
