AOPA Pilot Magazine - August 2021 - 78

Contributing to the accident were
the pilot's improper use of the enhanced
ground proximity warning system's terrain
inhibit switch and the air traffic
controller's failure to issue a safety alert
regarding the proximity of the tower. "
However, during the investigation,
three troubling matters emerged that-
while not determined to have contributed
to the accident-might have been indicative
of a laissez-faire flight operation's
protocol: The King Air's EGPWS database
had never been updated and it was
out of date; the airplane's next phase
inspection was overdue by more than
134 hours; and, the 63-year old pilot-
who was also an active CFI and held an
instrument rating and multiple airplane,
helicopter, and type ratings-completed
his last flight review or equivalent on
February 9, 2009-no other records of
training or completion of an FAA flight
review were documented in the two
years preceding the accident.
But there are additional, remarkable
thoughts to reflect on.
According to the King Air's owner, the
pilot had flown into Nemacolin Airport
approximately five times before. The pilot's
normal habit was to disengage the terrain
inhibit switch after departure. When
engaged, an annunciator would illuminate
and a status message would indicate that
warnings were inhibited. But, for whatever
reason on this last flight, the pilot did
not see the message or follow his normal
habit-perhaps he had been interrupted
or distracted, or he may have simply had a
momentary lapse and forgotten to shut it off.
We will never know the answer to
why the pilot chose a direct flight route
near rising terrain and obstructions at a
cruise altitude of 3,100 feet msl-400 feet
below the published maximum elevation
figure of 3,500 feet msl. Because the pilot
was receiving radar service, he possibly
depended on the approach controller to
warn him of obstacles and terrain. Or,
unaware that the system's inhibit switch
was still engaged, he may have expected
visual and aural alerts from the EGWPS to
warn of any obstructions in his path during
this short VFR flight.
Although weather at Morgantown
permitted landing under visual flight
rules, the pilot would have encountered
reduced visibility and possibly IMC east
of the airport because of haze and cumuliform-type
clouds between 1,500 and
3,000 feet agl, affecting his ability to see
the communications tower.
Had the King Air pilot chosen a
higher altitude considering terrain,
obstructions, and the possibility of
adverse weather when planning the VFR
flight, he might have been able to safely
complete the short flight. Alternatively,
he could have filed an IFR flight plan.
Sure, it might have seemed a nuisance
for such a short hop-it would have
likely increased the flight's duration
and his workload. However, even flying
VFR, consulting the L29 IFR En Route
Low Altitude Chart would have alerted
him to an off route obstruction clearance
altitude (OROCA) of 7,100 feet msl along
his route. A great safeguard for both IFR
and VFR pilots-especially when flying
near a charted designated mountainous
area-the OROCA is based on the highest
possible elevation including both terrain
and other vertical obstructions in the
OROCA's quadrangle. And, unlike the
maximum elevation figure, the OROCA
also provides a 2,000-foot vertical buffer
inside the designated mountainous area.
In addition, the OROCA is determined
by analyzing obstructions in a four nautical
mile area around its quadrangle,
offering the same lateral clearance as
an airway should the line of intended
flight follow a ticked line of latitude or
longitude.
Collision avoidance /
Collision avoidance is one of the most basic responsibilities of a pilot operating an aircraft
in visual conditions. ASI's Collision Avoidance Safety Spotlight provides strategies and
tactics you can use to keep the skies safer for you, and for those you share it with.

AOPA PILOT / August 2021
Although the air traffic controller had
other flights to deal with, a safety alert
about the proximity of the communications
tower should have been issued to
the pilot receiving VFR traffic advisories.
Please, maintain situational awareness
at all times, even if ATC monitors
your flight. You're the pilot in command,
in charge of your life and that of your passengers.
So, fly safe and stay proficient.
