Looking for Ideas: -7 bag area tie downs
My buyer says Canada wants hard points in the baggage area for lashing stuff down. He could not provide criteria for meeting the regulation, so two questions:
1. From the knowledgeable, what is the requirement, if any?
2. How would you implement tie downs in a side-by-side?
I'm of the mind now to replace four 8-32 platenuts in opposite corners with 10-32 and screw in small eyebolts, such as I've seen on Cessnas.
What would you do?

Depends
When I imported my -4 the inspector did not require these "hard points". However consistency is not the strong point of the inspection system, so another inspector may require something different.
Your plan to change out the platenuts and screw in some eyebolts for this seems reasonable to me, although I would do all 4 corners.

How about cutting some slots in the baggage floor and having a steel eye pass through the floor and attach to the side of the baggage rib with a doubler to spread the load. They would look like one-half of a seat belt ancor.
For forward tie downs, you could buy some extra seat belt ancors and attached them on the aft side of the rear spar carrythrough using the same bolts as the seat belt ancor (longer bolts of course).

baggage tie downs
Hard point tie downs are indeed required for us Canucks. Van's has an option that they offer...looks something like this mounted in the four lower corners.

Frankly, for what these tie-down from Van's go for, I think rolling your own would be a lot less money.

I used 4 of the tie-downs from Van's. One in each corner of the baggage compartment of my -6A. They work great. The base is aluminum and of minimal weight. They come with 10-32 threaded screws, but I used 8-32 size to keep the plate nut size down.
Northern Tool has several size elastic cargo nets. I found one that fits just right. The split ring on the removable tie-down part can be opened and allow the net material to be inserted into the ring.
Except for the round aluminum mounting plate, my entire net is easily removable when not needed.
This same type of hardware is available in steel elsewhere, but is considerably heavier. This type of hardware is also available in many different configurations online and as motorcycle as tie down solutions.

I also used Van's tied owns, but I installed them with rivnuts. I didn't want to drill out the blind rivets that hold the baggage compartment floor to the ribs. http://www.aircraftspruce.com/catalo...es/rivnuts.php

Hinges
I used hinges and a thick (.060) piece of aluminum. Rivet half of hinge to floor. and other half to aluminum with hole in it for tie downs. They can also be removed (half of it) when desired as well. Thought I had a pic of it but cant find it.

Tie down rings are actually very easy to install.
Scroll to the bottom of this page of my website and you will see how I installed them without removing the floor.

There's some helpful information in Advisory Circular 43.13-2B. Look at Chapter 12, "Cargo tiedown device installations."
Here's a link: http://www.faa.gov/documentLibrary/m...2043.13-2B.pdf
Good luck.

Bill, how heavy are your Pit Posse tie down anchors? Steel or Aluminum?
My 7 is already tail heavy.
