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.

Federal Aviation Administration (FAA), DOT. ACTION: Notice of final policy. 48627 safety to seated occupants. 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; 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 Sec.  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 Sec.  
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 Sec.  25.562 and will streamline the seat certification process by 
reducing the costs and time associated with seat certification.
    Seat bottom cushion changes must be evaluated to determine that 
compliance with Sec.  25.562 is maintained when considering both the 
14g downward test and the 16g longitudinal test specified in the 
regulation. This policy addresses demonstrating compliance with the 
lumbar load criteria of Sec.  25.562(c)(2) that is determined in a 14g 
downward test.
