Jim’s Analysis
This is indeed very sad. Many of us
knew and respected Val, the pilot. I
know she would have wanted us to
learn from her experience, so that
the lives of others may be saved. So
any criticisms that may be offered
by myself or others are with the best
intent in the world.
Let’s go back to the question that
I always ask after an accident. Could
you see it coming? In other words
if you were in the back seat of the
aircraft, at what stage would you be
saying to yourself “This is starting
to look unsafe. Given a free choice I
would rather not be here”?
Not an easy question in this case,

because we don’t have the advantage
that the pilot had, of being able to
look out of the window and make an
assessment of the weather. All we can
do is try to read between the lines of
this report and try to visualise what
was happening.
First, February is high-season for
afternoon thunderstorms around the
Johannesburg/Pretoria area. They
are pretty much guaranteed. This
being so I would not be happy to
venture into cloud in an aeroplane,
which, although well-equipped, I
would regard as suitable for pansy
instrument flying – climbing or
descending through a couple of
thousand of feet of stratus.

For “proper” IF, I believe you
need two engines, de-icing, a good
auto-pilot, a good current IF co-
pilot, weather radar and stormscope.
In this case I believe the last two
would have prevented the pilot from
entering an active thunderstorm cell.
So when would I have started
squirming in the back seat? When
I saw us heading towards an area of
CBs, with a weather radar that was
known to be intermittent.
I have to say that I don’t believe the
findings of the investigators when
they say she lost control of the aircraft,
although this could have happened
following a lightning strike. My opinion
is the aircraft broke up in flight.

Because of the pilot’s vast
experience, and seemingly well
equipped aircraft, I take this accident
very seriously, and have elicited
comments from two aviation forums
which might throw additional light
on the accident.

Someone should tell the CAA that
they absolutely must not use the
term “inadvertently”. As apparently
that is not possible, as has been
pointed out so many times on
AV C O M.

I was standing outside here at Vans...
We were watching this dramatic
thunderstorm passing to the south.
It was actually quite magnificent.
A light-blue Cessna 210 passed
overhead in a south-westerly
direction – directly into the path
of the huge storm. I remarked:
“I’m glad I’m here on the ground
and not up there!”

SYNOPSIS
On 7 February 2002 at 0526Z the
aircraft departed from Lanseria
Airport for a flight to Vereenging
in order to uplift two passengers
(one of whom was a prospective

buyer). After collecting the
two passengers, the aircraft
departed for Pietersburg and
landed there at 1042Z.
The aircraft again departed
from Pietersburg at 1438Z
approximately four hours
later for the return flight to
Vereeniging. Approximately
23 minutes after take-off while
approximately 26 nm outbound,
the pilot requested to return to
Pietersburg due to poor weather,
which prevented continuing on a
VFR flight to Vereeniging. While
routing back to Pietersburg
and while in discussion with
Pietersburg ATC and Lowveld
Information, the pilot filed an IFR
flight plan for the return flight to
Vereeniging with Lanseria as the
alternate aerodrome. The aircraft
was given a squawk code of 7417
and was cleared for FL140.
At 1553Z the aircraft was
approximately 5 nm from the
Johannesburg TMA at FL120 and
was given descent clearance for
FL100. The pilot continued with

her descent but reported strong
up-draughts.
The aircraft continued
towards Vereeniging and while
approximately 10 nm North
of Vereeniging aerodrome,
the pilot requested to divert
to Lanseria due to being in a
tremendous storm. The aircraft
turned out to the right and the
last radar return showed the
aircraft heading in a Westerly
direction at FL083 at a ground
speed of 160 knots.
The wreckage of the aircraft
was later found in the same area
where radar contact was lost.
The aircraft was destroyed
and all three occupants on board
were fatally injured

PROBABLE CAUSE
The instrument rated Airline
Transport pilot inadvertently
entered a severe storm and in
an attempt to turn out of the
storm and divert to Lanseria,
lost control of the aircraft and
collided with the ground.
