Tip up canopy hinge pin

[Roy Samuelson]

For those not using the canopy jettison set up, how are you securing the hinge? Bolt instead of the pin? Safetying the pin?

Thanks for the help,

Roy

Bolt

I used the appropriate length -4 bolt and self locking nut.

I didn't use a nylok nut (AN365) because this is rotating hardware...at least nothing prevents it from rotating...and thus loosening. I used an AN4 bolt with a drilled shaft, and an AN310 castle nut & cotter pin.

I agree...it's EXTREMELY unlikely that a self-locking nut would loosen up in this location. But since that hardware can't be inspected easily (at least not on a regular basis), and since a departing canopy can really ruin your day, I took no chances.

Lock Pin

I used an AN4 bolt with the hole at the end, a couple of washers and an appropriately sized lock pin. Still allows you to pull the lock pin and get the canopy off pretty easily.

Rusty.. if you use an AN 4 bolt, the threaded portion can rest on one of the bearing surfaces, which is not good practice for a rotating part.

You should use several washers (probably more than 2, not easy to install), but the best solution is an AN394/MS20392 Clevis pin.
