Spoilers on Saturday
by Sal deFrancesco
I had already had two flights that Saturday, but an opportunity for
use of the club Blanik opened up at 4:30 PM and I decided to go for
one more flight. Having just been used for a lesson, the Blanik was
in position on the runway, so I jumped in and got myself settled and
set for a late afternoon tow.
The tow started normally, but I noticed that it was taking longer to
get airborne. The tow plane was struggling to get off the ground but
finally did so and we started to climb. At about 100 feet the climb
got very shallow and at that time John Mahoney, the tow plane pilot,
wagged his rudder once then twice. I thought he was losing power and
could not release me. It appeared to me that we were both about to go
into the trees. I released so at least the tow plane would make it
out.
As soon as I released, I noticed my airspeed drop rapidly…spoilers
open! I quickly closed them and re-trimmed the Blanik for best glide.
I was low over the trees and thought I was going to make a tree
landing.
Fortunately there was a field directly in front of me. I wasn't sure
I was going to make it and knew that the worst thing that could
happen was to try to make the field and fail, catching the wing at
the edge of the trees and cart-wheeling in. This would be bad for the
Blanik and worse...very bad for me! I selected a point about 100 feet
before the end of the trees as the point of no return — there I would
decide whether I was going to make it to the field or turn right and
attempt a tree landing. I set my speed at 55-60 (best glide with just
a bit more energy to spare) and when I reached that point my airspeed
was good and height was enough (just!) to make the field.
I cleared the trees, made a quick 90-degree turn to line up with the
field and made a soft landing. Well, I survived, the plane was not
damaged and I made probably the shortest cross-country flight on club
record! I was safe and out of the cockpit, walking towards the road,
having signaled the tow plane.
I knew I had made some mistakes.
First, how did the spoilers open? Did I miss them in the preflight?
If they are not fully locked, the air pressure at towing speeds will
open the spoilers all the way. I also misinterpreted the signal for
spoiler open. Wagging the rudder is the signal and wagging the tail
means tow plane cannot release. I chose the latter meaning.
Not excusing my shortcomings on this occasion, I will say that radio
contact would have informed me directly that my spoilers were opened
and the flight would have concluded normally. I have since purchased
a hand held radio for this purpose.
First, I want to thank John Mahoney for his great job of sticking
with me and allowing me enough height to get to the field. He would
have been justified in releasing me, but he made a great effort to
help get me to a safe landing.
I want to thank all the guys who came and broke down the Blanik. The
guys were on the scene in minutes and we were back on the field in
less than 1½ hours. I was safe, the Blanik was safe and I had a lot
to think about. It was my turn to buy beer, a very small price to pay
for all the help I received and my fortunate outcome.
