Rather than having an unusual operation trigger extra
study, we pressed on and blew the turn. Another lesson:
take more care when operations are different than normal.
Our reporter’s advice applies to everyone operating near
an airport construction area—flight crews, controllers,
ground crews, and construction crews.
Low-Level Flight
One moral of the next report is always check the PQ
(Popularity Quotient) of your passengers before you fly.
n My passenger was buying some farm land in the area. We
were circling the area at 600-700 feet AGL. She then wanted
to fly over her condominium complex. I climbed to maintain
at least 500 feet AGL. We circled the complex 7 or 8 times,
never flying directly overhead the building.
Apparently the neighbors knew this woman was flying over
the complex; she was not well-liked by her neighbors. They
called the police and complained that we were “buzzing” the
complex. The area was an uncongested area with corn fields
and farm land surrounding the complex.
Our reporter made an arbitrary decision that the corn fields
on either side of the condo complex constituted an
“uncongested” area. They did not.
Distraction by objects or activity on the ground is a common
problem in low-altitude flying. The next reporter set the
scene for an incident by sight-seeing at only 500 feet AGL,
then got caught up in the fun on the ground.
n I came upon a softball game taking place. Some of the
players were friends of mine, so I reduced power to get closer
to see if I could pick them out. I became too focused on the
players and failed to realize how low and close to the field I
was. Suddenly there was a row of trees ahead of me. I tried
to climb…but due to low airspeed, I struck one of the trees. I
proceeded directly back to the airstrip…with reduced elevator
control.
This reporter was very lucky. The softball teams were also
most fortunate that they didn’t have to scrape the airplane
off the outfield.
In our final report, a wily coyote won the day, as the pilot of
a predator control aircraft pursued. The co-pilot marksman
was having an off day:
n We spotted a coyote…made the first pass at it and missed
the shot. We circled again to make a second pass. The coyote
ran to a wash and down it. This wash had a hill beside it,
which hid a tree...
Any empathetic reader can fill in the balance of the scenario.
The airplane struck the tree and damaged its wing, as the
unscathed coyote trotted down the dry creek bed. In this
case, maintaining obstacle clearance should have been the
pilot’s highest priority, since the aircraft was operating so
close to the ground.
Low Level Missions

A Growing GA Hazard
Weather-related fatal accidents once topped the light
aircraft accident list. However, according to the 1996 Nall
report, an annual safety report published by the Aircraft
Owners and Pilots Association Flight Safety Foundation,
low-level maneuvering has jumped to number one as the
cause of fatalities in single-engine fixed-gear aircraft, with
36.1% of fatal accidents. More than half of all maneuvering
fatalities occurred during buzzing or other unauthorized
aircraft operations.
As every student of Aerodynamics 101 knows, low and slow
is one of the most hazardous aerodynamic conditions—the
“slow” bringing the aircraft close to stall, and the “low”
putting the aircraft and its pilot in an area where recovery
is altitudinally limited. In recognition of the low-and-slow
flight hazard, FAR 91.119 prohibits operation of an aircraft
at an altitude which, in the event of a power failure, does
not allow a safe landing without hazard to persons or
property on the surface.
Reports submitted to ASRS by general aviation pilots
illustrate a broad range of low-level flying incidents, many
of them resulting from impromptu, unplanned flights.

and retired head of the Foothill College Aviation
Department in Los Altos Hills, California.
The next reporter was planning ahead—to the next
weekend’s activities.
n I was on my way home from a hunting trip and was
expecting friends in a week or so who were bringing their
boat. I decided to take a look at the lake as I had never been
there. I made two passes over the lake to look at it. I saw one
boat on the lake and I was to its side by at least 500 feet. I
