ACTION: Notice of final policy. AGENCY: SUMMARY: The Federal Aviation Administration (FAA) announces the availability of final policy on a component method for demonstrating that a seat with a replacement bottom cushion complies with § 25.562(c)(2). This policy addresses non-flotation monolithic (single layer) cushions. DATES: This final policy was issued by the Transport Airplane Directorate on August 9, 2005.

SUPPLEMENTARY INFORMATION: A notice of proposed policy; request for comments, was published in the Federal Register on April 11, 2005 (70 FR 18453). Three commenters responded to the request for comments. Background Historically, substantiating changes to the bottom cushion of a seat certificated to § 25.562 that could affect the lumbar load typically required a full-scale 14g downward dynamic test using the actual seat. Industry desired a quicker and less expensive method in lieu of full scale testing. As a result, the FAA funded a research project to develop a component test methodology for demonstrating that a replacement bottom cushion would not produce a higher lumbar load than a certificated bottom cushion for a seat certificated to § 25.562. This research resulted in an acceptable methodology that is documented in DOT/FAA/AR– 05/5,I ‘‘Development and Validation of an Aircraft Seat Cushion Component Test—Volume I,’’ dated March 2005. This method provides a simplified means of demonstrating compliance with § 25.562 and will streamline the seat certification process by reducing the costs and time associated with seat certification. 13:40 Aug 17, 2005 Jkt 205001 Issued in Renton, Washington, on August 9, 2005.

Seat performance, including the restraint system, under dynamic conditions as defined in § 25.562, is an important consideration of this amendment. Replacing a restraint system on a seat certified under § 25.562 requires new dynamic test(s) to be conduct using the actual seat. These dynamic tests can be costly and time-consuming. The FAA conducted research and found an acceptable new method of certifying restraint systems using a rigid seat fixture instead of the actual seat during dynamic tests. This method will significantly reduce the cost and time associated with certifying replacement restraint systems. This policy memorandum presents this new means of compliance.

Disposition of Comments

    A notice of proposed policy was published in the Federal Register 
on April 11, 2005. Five (5) commenters responded to the request for 
comments.

Background

    The FAA has issued Amendment 25-64 to provide an increased level of 
safety to seated occupants. Seat performance, including the restraint 
system, under dynamic conditions as defined in Sec.  25.562, is an 
important consideration of this amendment. Replacing a restraint system 
on a seat certified under Sec.  25.562 requires new dynamic test(s) to 
be conduct using the actual seat. These dynamic tests can be costly and 
time-consuming. The FAA conducted research and found an acceptable new 
method of certifying restraint systems using a rigid seat fixture 
instead of the actual seat during dynamic tests. This method will 
significantly reduce the cost and time associated with certifying 
replacement restraint systems. This policy memorandum presents this new 
means of compliance.
    The final policy as well as the disposition of public comments 
received are available on the Internet at the following address: http:/
