Some aircraft came with Flight Manuals which provided an approved procedure for landing without elevator control. I know that many Cessna manuals have it, but I do not have any recent Piper manuals to review. I've had a look through the regs, but cannot find the reference on the regulation side. For those with access to a later model Cherokee Flight Manual, it might be worth a look in Section 3 to see if this procedure has been presented. It seems like a recent awareness of this procedure could be timely right now.
