SUPPLEMENTARY INFORMATION:

Comments Invited

We invite interested parties to submit comments on the proposed airworthiness standards to the address specified above. The FAA will consider all communications received on or before the closing date. These are preliminary proposed airworthiness standards as certification evaluation is ongoing. As such, we also plan to issue a subsequent Notice, addressing the final proposed standards and any comments received in response to this advance Notice prior to issuing the final acceptance. Commenting on this advance Notice does not preclude commenting on the subsequent Notice.

Background

The “special class” category for aircraft was created specifically for non-conventional aircraft for which airworthiness standards have not been issued and provides a means for applicants to propose airworthiness standards for their particular special class aircraft. The FAA procedure establishing appropriate airworthiness standards includes reviewing and possibly revising the application proposal, publication of the submittal in the Federal Register for public review and comment, and addressing the comments. After all necessary revisions, the standards are published as approved FAA airworthiness standards.

Accordingly, the applicant for the BA609 Tiltrotor has submitted a request to the FAA to include the applicable requirements of those airworthiness requirements contained in Title 14 of the Code of Federal Regulations, parts 23, 25, and 29 found by the Administrator to be appropriate for the BA609 Tiltrotor or such airworthiness criteria as the Administrator may find appropriate for this special class aircraft that provides an acceptable level of safety equivalent to the level of safety provided in the existing airworthiness standards. We have considered the applicant's proposal and have determined that those 14 CFR parts 23, 25, and 29 requirements and certain additional airworthiness standards should apply.
