Default Fatal Towplane Accident 5-9-20

I know (sadly first hand) it's way too easy to start launch with the canopy handle in the lock position, but the canopy not locked because it was a bit up when 'locked'.

That added the push on the plexi as belt and suspenders. That's the best launch procedure mod I've seen to deal with this usually distraction related issue.

It would be interesting to hear of something better?

Default Fatal Towplane Accident 5-9-20

On Monday, June 1, 2020 ...

I hesitate to even bring this up, but my club had a ballooning accident last year involving a brand new tow pilot making his first tow and an instructor Glider pilot making his first flight the year. The Glider ballooned on takeoff and the tow pilot toggled him off, immediately............some said “too soon”? I didn’t see it and take no position on the issue, but I did see the broken Sailplane sitting in the sagebrush! Our club has no way to give dual tow pilot instruction . A new tow pilot is really making his “first tow”, with no dual instruction on towing whatsoever!
Food for thought,
JJ


In the States, you don't tow anyone until you've had three actual or simulated tows with a qualified towpilot aboard. Clubs with only Pawnees to tow with use some other aircraft with dual controls to do simulated tows to check out new tug pilots. From the few details you've provided, I'd say your brand new towpilot was well trained to punch off a glider that had ballooned close to the ground. I'll accept some exploration of the tow envelope above 1500' but below that, get out of position enough to make me wonder what's going on and you'll be getting my end of the rope post haste. I'm sick and tired of reading of another glider pilot explaining why he's alive and his towpilot is dead.

In a 2- place ship, the front seat pilot can check both canopies by simply shoving up on each canopy right over his head, even though the guy in the other seat said his is closed and locked...........good to double check!
Another procedure that my club requires is a radio call stating that the gliders canopy is closed and locked, spoilers are closed and locked, slack is out and Glider is ready for takeoff! In the past I have thought this radio call wasn’t necessary in a sanction contest, but if it saves someone’s life, I’ll willingly go along with it!

One of the issue that is not talked about a lot in the glider community is intentional noncompliance. In no way am I implying that this is the case in the crash we are discussing - I am trying to figure out why this scenario is reoccurring in the glider world and believe that intentional noncompliance could be a factor.

I’ve witnessed it as a professional pilot and have seen it in the glider community.

Here is an accident that really highlighted it for professionals: https://nbaa.org/wp-content/uploads/...rt-AAR1503.pdf - if you don’t feel like reading it through basically a Gulfstream crashed on takeoff and the gust lock was engaged and control checks were not done - creating several problems. The interesting fact was: “ Further, a review of QAR data revealed that the flight crewmembers had neglected to perform complete flight control checks before 98% of their previous 175 takeoffs in the airplane, indicating that this oversight was habitual and not an anomaly.” QAR = quick access recorder, like a flight data recorder.

There is some good information he https://nbaa.org/aircraft-operations...ing-the-risks/

The glider community is shrinking, accidents are up, insurance costs are up and a lot, if not all, of the accidents/incidents are the same causes that are always analyzed, rehashed, argued about and then blame is cast around but we can’t seem to fix it.

If there is to be a future we have to find a way to rectify these reoccurring problems. It’s a “sport” that kills more pilots than US Naval Aviation does per year, they fly jets, on and off boats, a lot more and obviously in more hazardous conditions.

We have a lot of work to do.

Regards, Tom

I also forgot to latch the canopy once, but it has a forward hinge, so it just rattled a bit. I latched it after releasing from tow. A side hinge canopy should ALWAYS get some fingerprints on the inside of the plexiglass. EVERY TIME! It's a lot easier (and CHEAPER!) to clean off the greasy fingerprints than to hunt down all the shards and pay for a replacement.


Fingerprints might not be necessary

I push up with knuckles of both hands, just next to my head

Any marks are usually out of my view and might even get wiped off by my hat

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.

This reminds me of the saying "an experienced pilot is one who no longer makes small mistakes".

One final thought: Get rid of all side opening canopies.

Yelling at people about checklists hasn't worked for anyone yet, as far as I can tell.


Once again, the "Ban the (insert selected pet peeve here)" cry is raised. Once again, over statistically insignificant occurrences that result in an accident.

Sure, upsetting a tow plane is serious, and sometimes tragic. But millions of side opening canopies have been successfully latched over decades by millions of pilots. Why is the call for banning something, with no economically feasible method of employing such a ban, so popular with some people? Are you suggesting that ALL Schempp-Hirth gliders, ALL Grobs, ALL Schweizers somehow be thrown away? Or sent back to the factory for an exorbitantly expensive retrofit (that would probably entail recertification by EASA and/or the FAA)?

I grow weary of hearing demands that "SOMETHING MUST BE DONE!"

One guy ****s his pants and we all have to wear diapers.

And the statement that "yelling at people about checklists isn't working for anyone" is especially fatuous. It obviously can't work in EVERY case, but saying it doesn't work at all, when it obviously does in the vast majority of instances is myopic, if not evidence of total blindness.

I have seen a couple of frightening canopy issues that did not result in anything awful, but were instructive. Here's my two cents:

You CANNOT rely on the glider pilot, regardless of experience, doing the right thing when a side-opening glider canopy pops open in flight. Glider clubs do not have the resources to train for this. So either we create the resources to train or we stop launching with the canopy unlatched.

Our club does have a wonderful simulator setup. I thought of hooking up a couple of squirrel cage fans or air compressor hoses and an air horn to simulate a canopy opening in flight. The noise needs to be significant and the airflow needs to induce tears. Still thinking about it.

The other approach is to commit to never, ever launching with the canopy open again. A few weeks ago instituted a mandatory radio call prior to take-off: "Sailplane XYZ canopy locked, air brakes in, ready for takeoff." Wing runners are trained to look for positive canopy check. Years before I started with the Navy, they instituted mandatory "three down and locked" call on final. That apparently was enough of a trigger to eliminate gear up landings. Maybe we can do the same with canopies.

One final thought: Get rid of all side opening canopies.

Yelling No , but pilots that march to their own drum must be talked to with authority. In aviation there is a thing called airman-ship . One must be open to constructive criticism and put their ego aside. If a pilot gets angry or refuses to listen they should be asked not to return, or their membership revoked by vote.

A safe launch requires a plethera of things to be right in the glider.

For my reptile brain, actually touching and moving works better than looking and saying. But I can see how different pilots have different best ways of dealing with these.

I've seen an attentive ground person check for a pilot that's not 'with it', provide extra time, limit distractions, and pause the launch if something seems out of place. For a club ship, physically verifying the canopy is locked sometimes makes sense if it can be done without breaking the pilot's train of thought. Past that, I'm not sure.

Training a new pilot probably needs a different story for the ideal ground guy, but if ground starts trying to enforce some specific get ready procedure, it seems a close call if he's helping or adding to the distractions and making things worse?


PS: I like my side opening canopy. But the last podcast with Dave talking about bailout issues are food for thought.

IME this is a job for the instructor: he needs to teach "close, lock and
check that the canopy is locked" from his victim's first flight. If a
student does this check from their first flight (yes, even a trial
flight!), it will get engrained as part of their pre-flight routine.

What the check is depends on the glider. In an ASK-21 I apply light
pressure to the canopy just behind my head, in a side-opening G103,
Puchacz or Junior I apply upward pressure to the lock body (NOT the
locking lever!) and in my Libelle I twist the lock into place (visual and
feel as the expanding rod goes into the bearing at each end, then flip
the vent lever lever up and down to check that the bottom of the canopy
center rises up and then pulls down onto its seal: soft 'D' section draft
excluder round the front coaming and thick foam door seal strip over the
wing.

Finally, in a T.21 Sedburgh there is no canopy check because its an open
cockpit.
