## Abstract

This final rule adds a provision to the existing requirements for fuel tank system fault tolerance evaluations that allows type certificate holders to use equivalent safety provisions for demonstrating compliance. The current regulations do not provide such provisions. This rulemaking will allow current certificate holders to use the same equivalent safety provisions already available to applicants for new or changed type design approvals.
