Discussion

We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 to include an AD that would apply to the specified products. That NPRM was published in the Federal Register on December 29, 2011 (76 FR 81889). That NPRM proposed to correct an unsafe condition for the specified products. The MCAI states:

Three cases of failure have been reported, affecting the same type of hydraulic accumulator as installed on SAAB 2000 aeroplanes, although all occurred on other aeroplane types. The reported cause of these failures has been traced to corrosion. Any of the end parts on the accumulator may depart from the pressure vessel if they are affected by corrosion.

This condition, if not detected and corrected, may lead to fatigue failure of a hydraulic accumulator, possibly resulting in damage to the aeroplane and injury to occupants. In addition, a quality issue during the replacement of the base material in the end parts of the accumulator may have affected the service life of the accumulator.

To address this unsafe condition, SAAB has introduced a new type of hydraulic accumulator, which is made of stainless steel.

For the reasons described above, this [EASA] AD requires the replacement of all Part Number (P/N) 08 8423 030 1 hydraulic accumulators with stainless steel P/N 40800– 2050 hydraulic accumulators and associated structural modifications in the nose landing gear bay. 

### You may obtain further information by examining the MCAI in the AD docket.

Comments

We gave the public the opportunity to participate in developing this AD. We have considered the comment received. Request To Include a Statement From the Service Information

Saab AB (the commenter) requested that we revise the NPRM (76 FR 81889, December 29, 2011) to include a statement as follows: ‘‘In addition, a quality issue during the replacement of the base material in the end parts of the accumulator may have affected the service life of the accumulator.’’

We infer that the commenter requested that we add the statement to the Discussion section of the NPRM (76 FR 81889, December 29, 2011). We agree that Saab Service Bulletin 2000–29–024, Revision 01, dated November 5, 2010, states, ‘‘In addition, a qualification issue during the change of the base material, for the end parts of the accumulator back in 1993, can have affected the life limit of the accumulator.’’ However, we have not included the statement in the final rule because we do not restate the Discussion section in the final rule. We have not changed the AD in this regard. Explanation of Additional Change Made to This AD

We have revised the heading and wording in paragraph (i) of this AD; this change has not changed the intent of that paragraph.

Conclusion

We reviewed the available data, including the comment received, and determined that air safety and the public interest require adopting the AD with the changes described previously— except for minor editorial changes. We have determined that these minor changes:

• Are consistent with the intent that was proposed in the NPRM (76 FR 81889, December 29, 2011) for correcting the unsafe condition; and

• Do not add any additional burden upon the public than was already proposed in the NPRM (76 FR 81889, December 29, 2011). Costs of Compliance

We estimate that this AD will affect 8 products of U.S. registry. We alsoestimate that it will take about 12 workhours per product to comply with the basic requirements of this AD. The average labor rate is $85 per work-hour. Required parts will cost about $9,995 per product. Where the service information lists required parts costs that are covered under warranty, we have assumed that there will be no charge for these parts. As we do not control warranty coverage for affected parties, some parties may incur costs higher than estimated here. Based on these figures, we estimate the cost of this AD to the U.S. operators to be $88,120, or $11,015 per product. 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 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 the 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.

We prepared a regulatory evaluation of the estimated costs to comply with this AD and placed it in the AD docket. Examining the AD Docket

You may examine the AD docket on the Internet at http:// www.regulations.gov; or in person at the Docket Operations office between 9 a.m. and 5 p.m., Monday through Friday, except Federal holidays. The AD docket contains the NPRM (76 FR 81889, December 29, 2011), the regulatory evaluation, any comments received, and other information. The street address for the Docket Operations office (telephone (800) 647–5527) is in the **ADDRESSES**

**SUPPLEMENTARY INFORMATION** 

### : History

After a recent review of aeronautical data, the Aeronautical Navigation Products Group identified the VOR Federal airway V–14 description published in FAA Order 7400.9, Airspace Designations and Reporting Points, did not match the airway information contained in the FAA’s aeronautical database or the charted depiction of the airway. When V–14 was amended in the Federal Register of May 7, 1990 (55 FR 18862), the St. Louis, MO, VOR/DME was deleted from the description in error. The FAA aeronautical database retained the
