Supplemental Door Latch

[slowflyin]

There was some discussion in another post regarding a secondary, passive, door latch for earlier models.   Does anyone have install pics or words of wisdom?

I am not sure about a latch for say but I  have heard of  pin I think upper portion of the leading edge of the door. I think the M20J's have this pin. I heard it is bugger to install and align the pin.

Yes, that's what I'm referring to.   I have the kit but it definitely looks like alignment may be crucial to it operating well.  I'm hoping someone has installed one and can offer their experience.

Alignment is critical, and there is only one chance during installation. Drill it slightly off and you're done.

I do not have this on my plane, but I did consider it once, several years ago.

Good luck!

I have installed the pin.  Yes, it is a fussy install.  You mark your spot, drill a smaller hole for the pin to insert in the airframe, and SLOWLY taking only a small amount of aluminum off at a time, file, or use a Dremel tool, to remove metal until the pin just clears the hole and there is no ability for the door to pull open due top the outside low pressure about the plane.

Slowing with patience otherwise you will screw it up.

its a 240$ kit, as others said measure twice cut once.  takes about 6 hours to install.  Its worth it.
