Commenters should identify AC 25-17A, and submit comments, in duplicate, to the address specified above. The Transport Standards Staff will consider all communications received on or before the closing date for comments before issuing the final AC.

Background

This proposed AC revision contains guidance pertinent to the cabin safety and crashworthiness type certification requirements of part 25 as amended by Amendments 25-1 through 25-112. Previously, two ACs on this subject have been available to the public:

• AC 25-17 was issued on 7/15/91. It covers Amendments 25-1 through 25-59.
• A proposed AC 25-17A revision was published on 10/7/99, for public comment. It covered Amendments 25-1 through 25-70. That revision was never issued as a final document.
• To assist in reviewing the proposed AC, the FAA identifies the additions/changes made to the guidance by highlighting the text changes the first time they appear. The baseline for identifying the changes to the guidance is the existing AC 25-17, dated 7/15/91.

Extension of Comment Period

Since publication of the notice, the FAA has received a request that the comment period for the notice be extended past its original closing date of march 16, 2006, to allow more time in which to study the proposal and to prepare comments on this very important issue.

The FAA has reviewed the request for consideration of an additional amount of time to comment on proposed AC 25-17A, and has determined that extending the comment period would be in the public interest and that good cause exists for taking this action. Accordingly, the comment period of proposed AC 25-17A is extended until May 1, 2006.

Issued in Renton, Washington, on March 7, 2006.

Acting Manager, Transport Airplane Directorate, Aircraft Certification Service.
