Burt, consider the following:
Page 9, Soaring Safety Foundation, Tow Pilot Training. The following is
in RED:
DEPENDING ON THE INSTALLATION OF THE TOW HITCH, IT MAY BE POSSIBLE
FOR THE RELEASE MECHANISM TO BECOME JAMMED DUE TO THE EXCESSIVELY HIGH
POSITION OF THE GLIDER. (AMERICAN STYLE HOOK)
In addition the Advisory Circular, Date 3/3/08, AC No 43.13-2B,
page 76 says:
WHEN THE GLIDER UNDER TOW OPERATES ABOVE A CERTAIN ANGLE TO THE TOW
PLANE, THE RING MAY SLIDE UPWARDS ON THE HOOK CAUSING EXCESSIVE LOAD ON
THE HOOK AND DIFFICULTY IN RELEASING THE TOW ROPE RING.
This confirms that the industry is well aware of the problems with
this device and as one who has experienced it first hand I can attest
and concur. Why is this known to this degree and has little to nothing
been done. In short, the industry is not as self regulating as perhaps
it should be.
I found myself 300 feet in the air, pointed at the ground, attached
to a student pilot who was not reacting and I was unable to release for
more reasons than just the Schweizer hook. Had the rope not broken
this conversation would not be taking place. I would have been a
statistic and a glider port would be facing my lawyer brother.
Recurrent training would have not been helpful with a 15 year old
student on her 3rd solo. Low tow is not helpful when the towplane is
just a few feet off the ground over the runway. Do you deny that there
have been fatalities in this country due to this mechanism at a critical
point?
I found some of your commets to be condescending. Canopies, tail
dollys, medical certificates. These do not address the problem I have
outlined and only serve to confuse the issue.
I take flying very seriously, I flew almost 7000 tows in 2 years and 8
months without scratching the paint or putting a wheel wrong. I enjoyed
my time at SLGP and wish them nothing but the safest and best going
forward.
Walt
