Note: The Aircraft Certification Service of the FAA maintains the "Aircraft Certification Draft Documents Open for Comment" website on the Internet at http://www.faa.gov/aircraft/draft_docs/. You are invited to comment on draft Advisory Circulars (ACs) provided on the website. We will no longer publish these documents in the RGL or publish an individual Federal Register Notice for each draft Advisory Circular that the FAA makes available for public comment.
