Safety First: Performing An
Aerial Ballet

Aerobatics comes
naturally for most birds. Soaring and swooping effortlessly in the
air, our avian friends delight in the freedom of unfettered airspace.
With a few exceptions, a bird's structure and natural ability allow it
to perform aerobatic maneuvers as a normal part of life. Pilots, on
the other hand, must acquire training to perform the same sort of
maneuvers that their feathered friends perform naturally.
The best example of
this is at air shows, where highly trained pilots fly intricate
maneuvers with precision and ease. The seemingly effortless manners
with which the pilots perform the maneuvers belie the discipline,
training and practice it takes to make the show a success. Despite the
obvious beauty of the aerobatic maneuvers, a certain modicum of
ever-present danger lurks in the background. Training and planning can
reduce the accident potential to a minimum. If this potentiality could
not be reduced to a tolerable level, there would probably not be air
shows for us to enjoy.
Which brings me to
the real topic of this article; some pilots'after being exposed to the
splendors of professional pilots performing graceful aerobatic
maneuvers'decide to attempt this for themselves. They take their
aircraft'generally a small aircraft not engineered for aerobatic
flight'out to some remote area and attempt to emulate the professional
aerobatic pilots' maneuvers. Granted, this is an infrequent
occurrence, but it does happen.
Several years ago a
complaint was made to our Flight Standards District Office that an
airplane was doing loops, rolls, and other assorted maneuvers over a
populated area. Activity such as this is not only foolhardy but
against the federal aviation regulations. During the course of
interviewing witnesses and passengers aboard the flight, we found that
the pilot was a private pilot and the aircraft was definitely not an
aircraft to be used for performing aerobatics. Needless to say, the
pilot disavowed any knowledge of the occurrence and went so far as to
say that the town where the aerobatics had been seen was not even on
the pilot's route.
The pilot was found
to be less than truthful and was given a violation for his actions.
The aircraft had undergone stresses that were not in the design
limitations and had to undergo a mandated inspection. Now the plot
thickens.
About a year or so
later that aircraft was sold, but not to some unsuspecting soul buying
an airplane and not realizing the stresses the airframe had been
through. It was purchased by one of the passengers on the flight that
the FAA investigated for illegal aerobatic maneuvers. Even though the
aircraft had undergone an inspection, there was always the possibility
that stress fractures had gone undetected. The new owner of the
aircraft was on a long cross-country flight when something happened
that caused the accident. To this day, the reason that it happened has
not been determined. You see, the aircraft apparently came apart in
flight and sank in several hundred feet of water. All that was found
of the airplane was a tip tank. Was the accident caused by stresses
imposed a few years back? Could turbulence have caused additional
undue stress on the airframe? Did the pilot lose control for some
reason? Weather was good at the time, so that was not the problem. We
can only speculate as to the factors that caused this tragic accident
to occur.
The moral to this
story is: You need to get proper flight training in an aerobatic
aircraft before experimenting with loops and rolls, etc. Also be sure
that the aircraft is certificated for aerobatic use and that the
appropriate inspections have been accomplished before flight.
I must say
that I have never had as much fun in my life as when I took aerobatic
flight lessons and found the pure thrill of flying an aircraft in an
aerial ballet. There is nothing quite like it and I would encourage
pilots to explore this as an addition to their continuing education in
flight. Safely learning the flight characteristics of an airplane and
realizing your limitations as a pilot will make you a more competent
pilot overall.
