Does a right side net ever have to be replaced?

[mitchntx1548534714]

15.17.9 of the CCR does not discuss SFI rating expiration, only use of and proper mounting.

 

15.10 discusses window "nets" and the requirement to be replaced ever 5 years and is abundantly clear. The window net and right side head restraint serves very similar purposes, but the CCR has two distinct sections on each item.

 

I searched the CMC rules and saw nothing there.

Right side head restraints do not expire based on a date. From NASA HQ:

"There currently is no mechanism or spec for the right side net expiration so we are just sticking with good condition until further notice"

Just so I am clear, you must have either a right side net or right side head restraint mechanism, as you would have with a full encapsulated seat. Correct?

Correct. However, be sure to check the CCR's for proper understanding.

Thanks Adam.

My question in regards to this topic is;

 

If I have an FIA approved HALO seat that is out of date and being used with a seatback brace (no holes drilled in seat of course), do I need a net or is the out of date halo seat acceptable?

An out of date FIA seat with a backbrace is acceptable. The halo on such a seat is also acceptable.
