There is no set time for changing seat belts. An inspection

missing TSO tags and snags. If the belts have been
in the sun for several years the belts start to deteriorate,
shrink and become hard. The hardened condition will
deteriorate the stretching ability of the webbing and
could create an unasafe condition. According to FAR
43 appendix D seat belts are inspected for poor condition
and apparent defects.

Patti,

that is not correct as I interpret it. The Gadringer belts in the 27B I
co-own have a 12 year TBO. The JAA data sheet states the time for the
belts (as well as the Tost tow hook) while the data sheet from
Gadringer dictates that the webbing is to be replaced.
