## Abstract

On December 4, 2012, the FAA published a final rule; request for comments (77 FR 71691) to make the existing regulation consistent with the FAA's intent and with the certification practice both before and after the adoption of the existing rule. The 2012 final rule clarifies what an applicant must show regarding a "changed product" to comply with applicable standards and became effective on February 4, 2013. We sought public comment on that final rule even though it is only clarifying in nature. This action responds to the public comments the FAA received.
