Default Fatal Towplane Accident 5-9-20

Very sad to read this tragic news this morning.

Comments (anonymous) on the webpage indicate kiting may have been a significant factor.

Sincere condolences to the family of the tow pilot and to the members of the club.

Condolences to all involved.

While it is near impossible to engineer out all the potential for such an occurrence in towing there are things that should be done to all tow planes to mitigate these conditions. I'll not get into them but those who know me know what I think. While training is important, training should never take a back seat to giving the tow pilot every chance in the world to escape with his or her life.

Aside from eliminating human reaction time with an elevator at stop triggering an instant tow release, I'm not sure how to fix low level kiting at the tow. That would cause more problems.

On the other end of the rope, we have a separate sign off for aero, winch and motor launch. For me, it would have been useful if there was an additional for CG which requires a specific test to verify an understanding of kiting.

(RAS is all about fixing the problem before we know what the problem is. It will be interesting to see what the NTSB says about this in terms of mitigations.)

Definitely a sad day.

I am not the most experienced tow pilot on this site but I do have 7000 tows under my belt. I have survived a couple of kiting incidents, one at about 350 feet and the student didn't release. Had the rope not broken I would have been dead, the Schweizer release and associated release handle were useless for a couple of reasons. I'll not elaborate, those who know me know what I have to say regarding this. As for RAX being all about fixing problems....SHIRLEY you jest and yes I called you Shirley.

Watching that video of the wreck is shocking.
Its crazy how quickly aero towing can go sideways.
Thoughts and prayers to all involved.

We all know how the self-release works on the glider side at winch launching: at a certain angle the rope puts a pressure on a lever which causes the release. Isn't it technically simple to have a similar solution on the tow plane side, a lever above the rope, which pressed at kiting would release the rope immediately? Where am I wrong?

There have been some proposed engineering solutions, and even prototypes built of automatic tow releases to prevent kiting accidents. I believe the main problem has been that the difference in the angle of the rope relative to the release between normal tow and kiting is very small. Also, I think there was pushback from insurance companies regarding anything that might cause a premature release.

I do not know the specifics of this accident. But it is well known that the Schweitzer hook is vulnerable. The release mounting on the floor is hard or impossible to reach is a sever kiting. This has been hashed about in r.a.s. for years. I would be petrified to fly behind a "automatic" release.

In my opinion, it should be required for the towpilot to be able to keep his hand on the release for the first 500ft. In Pawnees, this can be done, with wrist also lying on the throttle to ensure it stays full forward.

Condolences to everybody in this tragedy. I am curious as to how many hours the glider pilot had? It says in the report that he landed safely. He should be charged with a crime.
