I ran across the following while looking for something else.
There was a recent discussion about whether it is acceptable to continue flying through an annual inspection with deferred U/S equipment. This should help those wondering. Just came out last year.
Short answer - yes it is ok, as long as the deferred equipment is re-inspected at the annual.
