Cargo Nets

[B2C2]

The plane is a 1969 T337D. All six seats are independently installed on seat rails and relatively easily removed.

These guys custom make cargo nets in any size & strength you want, with tiedowns where you want them. I'd get one rated for 10x my cargo weight.

I'm not sure how you'd get tiedown points in the ceiling.

Are they STC'd?

[JimC]

No. Does a cargo net need to be STC'ed?

Well ............................ check with your A/P - IA

AC 43.13-2B, Chapter 12, Section 1203 (a) (1-3) covers "Cargo Tiedown Devices." It says "Cargo tiedown devices may be assembled from webbing, nets, rope, cables, fittings, or other material that conforms to a FAA-PMA, TSO, NAS, AN, or MIL-SPEC standards[sic]". Note that the AC covers the raw materials, not the finished net.

No mention is made of an STC requirement.

The website of the manufacturer I cited says they make nets for "military, police, fire, government, aviation and marine applications."

I leave the rest of the exercise to the reader.

Thanks for the pointer to the cargo net supplier. Looks like a first class outfit. I can use the existing seat belt tie down points for attaching the cargo net to the floor. I'm sure they are strong enough. I asked my A/P about ceiling attach points and he suggested I post a question here. Looks like it's not something that is commonly done for this airframe.
