RIN 2120-AA64
 AGENCY: Federal Aviation Administration (FAA), DOT.
 ACTION: Final rule.
 SUMMARY: We are superseding an existing airworthiness directive (AD) for Goodrich Evacuation Systems approved under TSO TSO-C69b and installed on Model A330-200 and -300 series airplanes, Model A340-200 and -300 series airplanes, and Model A340-500 and -600 series airplanes. That AD currently requires inspecting to determine the part number of the pressure relief valves on the affected Goodrich evacuation systems, and corrective action if necessary. This new AD requires inspecting to determine the part number of the pressure relief valves on the affected Goodrich evacuation systems and replacing certain pressure relief valves, and adds airplanes to the applicability. This AD was prompted by reports that during workshop testing, certain pressure relief valves, which were required by the existing AD, did not seal and allowed the pressure in certain slides/rafts to fall below the minimum raft mode pressure for the unit. We are issuing this AD to prevent loss of pressure in the escape slides/rafts after an emergency evacuation, which could result in inadequate buoyancy to support the raft's passenger capacity during ditching and increase the chance for injury to raft passengers.
 DATES: This AD is effective May 4, 2012. The Director of the Federal Register approved the incorporation by reference of certain publications listed in the AD as of May 4, 2012.

SUPPLEMENTARY INFORMATION: 
                    ( print page 19070) Discussion We issued a supplemental notice of proposed rulemaking (SNPRM) to amend 14 CFR part 39 to supersede AD 2007-23-01, Amendment 39-15247 (72 FR 62568, November 6, 2007). That AD applies to the specified products. The SNPRM was published in the 
                    **Federal Register**
                     on December 29, 2011 (76 FR 81885). The original NPRM (76 FR 15229, March 21, 2011) proposed to require inspecting to determine the part number of the pressure relief valves on the affected Goodrich evacuation systems and replacing certain pressure relief valves. The original NPRM also added Model A330-223F and -243F airplanes to the applicability. The SNPRM proposed to add Model A330-302 and -303 airplanes to the applicability. Comments We gave the public the opportunity to participate in developing this AD. We received no comments on the SNPRM (76 FR 81885, December 29, 2011) or on the determination of the cost to the public. Conclusion We reviewed the relevant data and determined that air safety and the public interest require adopting the AD as proposed. Costs of Compliance We estimate that this AD affects 41 airplanes of U.S. registry. We estimate the following costs to comply with this AD: Estimated Costs
Action
Labor cost
Parts cost
Cost per 
                             product
Cost on U.S. operatorsInspection to determine part numbers
1 work-hour × $85 per hour = $85

$3,485
 We estimate the following costs to do any necessary replacements that would be required based on the results of the inspection. We have no way of determining the number of aircraft that might need these replacements. On-Condition Costs

Parts cost
Cost per productValve replacement
1 work-hour × $85 per hour = $85
$775
$860 per slide.
 According to the manufacturer, some of the costs of this AD may be covered under warranty, thereby reducing the cost impact on affected individuals. We do not control warranty coverage for affected individuals. As a result, we have included all costs in our cost estimate. Authority for This Rulemaking Title 49 of the United States Code specifies the FAA's authority to issue rules on aviation safety. Subtitle I, section 106, describes the authority of the FAA Administrator. Subtitle VII, Aviation Programs, describes in more detail the scope of the Agency's authority. We are issuing this rulemaking under the authority described in subtitle VII, part A, subpart III, section 44701, “General requirements.” Under that section, Congress charges the FAA with promoting safe flight of civil aircraft in air commerce by prescribing regulations for practices, methods, and procedures the Administrator finds necessary for safety in air commerce. This regulation is within the scope of that authority because it addresses an unsafe condition that is likely to exist or develop on products identified in this rulemaking action. Regulatory Findings We have determined that this AD will not have federalism implications under Executive Order 13132. This AD will not have a substantial direct effect on the States, on the relationship between the national government and the States, or on the distribution of power and responsibilities among the various levels of government. For the reasons discussed above, I certify that this AD: (1) Is not a “significant regulatory action” under Executive Order 12866, (2) Is not a “significant rule” under DOT Regulatory Policies and Procedures (44 FR 11034, February 26, 1979), (3) Will not affect intrastate aviation in Alaska, and (4) Will not have a significant economic impact, positive or negative, on a substantial number of small entities under the criteria of the Regulatory Flexibility Act.

A review of airplane maintenance records or the system identification placard on the girt is acceptable in lieu of this inspection if the part number of the pressure relief valve can be conclusively determined from that review. (h) Part Replacement If any valve having P/N 4A3641-1, 4A3791-3, 4A3641-26, or 4A3791-6 is identified during the inspection or review specified in paragraph (g) of this AD: Before further flight, do the applicable actions required by paragraphs (h)(1) and (h)(2) of this AD: (1) Replace all pressure relief valves having P/Ns 4A3641-1 and 4A3791-3 with pressure relief valves having P/N 115815-1, and mark the system identification placard on the girt, in accordance with the Accomplishment Instructions of Goodrich Service Bulletin 7A1508/09/10/39-25-373, Revision 3, dated March 30, 2011. (2) Replace all pressure relief valves having P/Ns 4A3641-26 and 4A3791-6 with pressure relief valves having P/N 115815-1 (for evacuation systems having P/N 4A3934 series units) or 115815-2 (for evacuation systems having P/N 4A3928 series units); and mark the system identification placard on the girt; in accordance with the Accomplishment Instructions of Goodrich Service Bulletin 4A3928/4A3934-25-374, Revision 2, dated March 30, 2011.
