L'Hotelier Fitting Safety Pins

Those bobby pins are used extensively on my Stemme and I lost two that
fell out of their retaining strings during taxiing operations leaving me
with only one spare. A quick search found 1.2 mm hitch pins at WalMart
(of all places). I got a bag of 50 pins for under $8. Here's a link

for anyone needing the same. I've tried them and they fit.

Ah yes, the aviation department of Walmart; personally I prefer McMasterCarr's aviation line, or locally the aviation branch of Rural King, but in a pinch...

Way better than Harbor Freight's aircraft parts store!

When a fellow ASW-15 owner in my club lost some of his pins I bought a couple dozen of the AN safety pins mentioned in the LBA AD from Aircraft Spruce.. More expensive than the Walmart option but better? Not really. The Schleicher TN on the AD offers a pin part number to order from them the same style of pins you got at Walmart and says right in the TN that they are Ford parts. For some reason when my ASW-15 came over from Germany (1998) it had AN type pins on the airbrake connections (which use the up/down wedge L'Hoteliers) and the bobby pins on the ailerons (which have the rotating type L'Hoteliers). Another club member who has just bought an ASW-20 has been looking for the captive safety pins referred to in the AD as Schempp-Hirth pins - an ASW-19 in the club has them and they seem like a really good solution. So far no luck in finding a source for them.

Up here in the Great White North we frequently use the aviation department of Canadian Tire for our needs.

Good find and thanks Dan.
I keep safety wire in my trailer in case I loose a pin. The AD states "Enlarging the safety pin guide hole diameter to a min of 1.2mm (0.05 in.) to accommodate a safety wire or pin, as applicable.

But under that is what I wonder if anyone has done because I do not have this.

"Fabricating a placard (using â…› inch letters) with the following words:"

"All L'Hotellier control system connectors must be secured with safety wire, pins, or safety sleeves, as applicable, prior to operation." and

"Install this placard in the glider or sailplane within the pilot's clear view."

If you have not installed the placard, assuming the AD applies to your glider, you glider is not airworthy and should not have passed the last annual or condition inspection.
It's easy to do. Print it, laminate(office tape will do in a pinch) and install with double stick tape.

AD97-08-06 Note 1 "This AD does not apply to gliders and sailplanes that do not have a U.S. type certificate (i.e.., experimental category); however the FAA strongly recommends compliance with the intent of this AD for airplane involved in U.S. operation where a U.S. type certificate is not necessary.

Was it a pinned L'Hotelier that failed on the Nimbus 4M crash in Washington? Does anyone know of failures with properly pinned L'Hotelier?

I don't see how a properly connected and pinned fitting could fail
unless the ball or socket was worn beyond specifications. My guess,
with absolutely no actual information, would be that there was a
material failure and something broke rather than became disconnected.
It would be interesting to see pictures or read the NTSB report. Do you
have more information about the crash?

According to LBA AD 1993-001/3 the 1.2 mm pins are Ford reference
number 1473 931

Whether Ford still supply is another matter...!
