Install it right on the plane. Simply drill out the two rivets holding your old latch system on your door. You will use these two same holes to install the Blue Sky Latch. The latch is made from TPE (thermal plastic rubber), it has excellent weather ability, and stands up to extreme temperatures. Next use a hack saw blade and cut off that point on your door stem. Then use a small hammer and tap the strike on the end. Align your door using the phillips head adjustment on your door stem. Your done. The Thermal plastic rubber acts a bumper as well as a latch. You will really like this product!
You get all the hardware including structural AN screws and elastic stop nuts in the kit. Step by Step installation guide with photos showing how easy it is to install.
Also no issue installing two sets, one on a 150, the other on a 172. Dont get the other guys comment. These are pretty easy to install and after you get the alignment correct they work great. 4 hours to install? Cmon. More like less than 1.
Item works great for me. No problem installing them and it holds the door in place very well.
Im quite pleased with this product. It is a good solution to keeping the C-150 door open. You have to be careful when opening to not change the alignment. It is not perfect, but I can not think of a solution that would be better. Give is a try, it is not a lot of money.
A real pain to fit. With any Aerobat at least you can remove the doors which will help otherwise dont waste money. Getting the alignment right (up and down and angle of approach to the rubber cup) risks cracking the stem as you need to bend it. Stem MUST be removed from wing to adjust in vice. Result, after about 4 hours of messing about not including a paint job on the stem, is better than the original. Silicone lubricant vastly improves functionality.
This item is a complete joke and is a waste of time and money.
Per the supplier: No, it will not work on the 172. We do not offer a latch for the 172.
This item is sold in a pair. It will be enough for two doors.
Here is what the install paperwork states about FAA Approval and install: "Like the original Sky Catch, the Blue Sky Catch is designed to be easily installed by the aircraft owner, and is intended to be considered a 'minor alteration'. If you have any qualms about doing the installation yourself, we absolutely recommend you obtain the services of a licensed airframe mechanic. The caveat of course is the most licensed mechanics will be reluctant to attach parts to any certified airplane without STC/PMA documentation. The Blue Sky Catch is made of a rubber "tip" that simply pushes onto the end of the catch stem, and it would be easily removed if found unacceptable by authorities. The catch attached to the door dips a little further into the regulatory gray area. The door catch must be held in place by two fasteners. It too is easily removed, but it does require replacement of the original friction door catch, by drilling out the two rivets that secure the original part. If there is any doubt or questions about the legality of installing the Blue Sky Catches, we recommend you request a 337 field approval for their installation. If you fail to obtain regulatory approval, and are unwilling to install catches without it, you may request them for a full refund, no questions asked."
