These proposed regulations would require TC Holders and STC Holders to develop damage tolerance data that would support operator compliance with 14 CFR 121.1109 and 14 CFR 129.109, the Aging Airplane Safety Final Rule (AASFR) (currently found at §§ 121.370(a) and 129.16) with respect to repairs and alterations. Sections 121.370(a) and 129.16 require operators of certain transport airplane models to incorporate into their maintenance program damage tolerance-based inspections and procedures for structure susceptible to fatigue cracking that could contribute to a catastrophic failure. The proposed AC refers to that type of structure as fatigue critical structure. The proposed AC is applicable to repairs and alterations that affect fatigue critical structure. The proposed AC also provides guidance for new and existing repairs and alterations made to the original, as delivered, airplane structural configuration, as well as repairs to alterations.

SUMMARY: The Surface Transportation Board is scheduled to relocate over the period of February 28-March 4, 2007. The Board is giving notice of prerelocation and post-relocation procedures. The Board’s new address will be: Surface Transportation Board, 395 E Street, SW., Washington, DC 20423–0001. EFFECTIVE DATE: February 28, 2007. FOR FURTHER INFORMATION CONTACT: Joseph H. Dettmar, (202) 565–1609 [after March 4, 2007, (202) 245–0395]. [Assistance for the hearing impaired is available through the Federal Information Relay Service (FIRS) at: (800) 877–8339.] SUPPLEMENTARY INFORMATION: The Board is issuing this notice to advise the public of its new location, effective March 5, 2007. The Board is scheduled to relocate its offices beginning at 5 p.m. on Wednesday, February 28, 2007. STB offices will be closed on March 1 and March 2, 2007, and will reopen for normal business operations at the new location beginning March 5, 2007. Its new address will be: Surface Transportation Board, 395 E Street, SW., Washington, DC 20423–0001. In addition, the Board is also giving the VerDate Aug<31>2005 15:22 Feb 26, 2007 Jkt 211001 public advance notice that normal service to the public, including normal case intake and processing, will not occur during the immediate relocation dates of February 28, 2007, through March 4, 2007, due to necessary equipment relocation and other disruptions anticipated during the relocation. Therefore, by this notice, the Board is announcing that mail will not be received and decisions will not be served on Thursday, March 1, 2007, and Friday, March 2, 2007. In particular, the Board will not: accept case filings or recordations; receive general mail; process cases; or issue decisions on these 2 days. Mail delivery and acceptance of filings and recordations will resume on March 5 at the new location. The Board will, for the duration of the period between March 1 and March 4, toll the time period for calculating the effective date of all Board decisions and notices that would otherwise be scheduled to take effect between March 1 and March 4, 2007. Because of the number of time-sensitive matters handled by the Board, the Board is providing advance notice that case filings that would begin a proceeding and trigger a deadline for processing or for effectiveness will not be accepted during the days needed to accomplish the agency’s relocation. Likewise, the STB will suspend its processing of recordations during the days involved in its relocation. The effectiveness of previously issued decisions, or previously filed self-executing notices that would otherwise be scheduled to take effect between March 1 and March 4, 2007, will be delayed one day for every calendar day during the March 1– 4 interval. This should alleviate any problems that could otherwise be presented for those persons who wish to seek a stay of effectiveness or problems that might otherwise occur in connection with processing of offers of financial assistance to continue rail service following Board approval of a rail line abandonment or discontinuance. The Board’s libraries will operate under the following schedule. The main library will be inaccessible from February 23 through March 5, 2007. The microfiche unit will be inaccessible from noon on February 28 through March 5, 2007. The tariff library will be inaccessible from February 28 through March 5, 2007. Recordations indexes will be inaccessible from February 23 through March 5, 2007. All Board library resources will reopen at the new location at the start of business on Tuesday, March 6, 2007. PO 00000 Frm 00158 Fmt 4703 Sfmt 4703 8835 Following the Board’s move, the agency’s information line will be 202– 245–0245.

Routine calls placed to the agency during its move will be returned beginning at the start of business at the new location on Monday, March 5, 2007. This action will not significantly affect either the quality of the human environment or the conservation of energy resources. Decided: February 21, 2007. By the Board, Chairman Nottingham.

Discussion

    This proposed AC provides guidance material to support Type 
Certificate (TC) and Supplemental Type Certificate (STC) Holder 
compliance with proposed rulemaking title 14 Code of Federal 
Regulations (14 CFR) 25.1823, Supplemental Structural Inspections, 
Holders of type certificates--Repairs; 14 CFR 25.1825, Supplemental 
Structural Inspections, Holders of type certificates--Alterations and 
repairs to alterations; 14 CFR 25.1827, Supplemental Structural 
Inspections, Holders of and applicants for a Supplemental type 
certificate--Alterations and repairs to alterations. These proposed 
regulations would require TC Holders and STC Holders to develop damage 
tolerance data that would support operator compliance with 14 CFR 
121.1109 and 14 CFR 129.109, the Aging Airplane Safety Final Rule 
(AASFR) (currently found at Sec. Sec.  121.370(a) and 129.16) with

require operators of certain transport airplane models to incorporate

procedures for structure susceptible to fatigue cracking that could

type of structure as fatigue critical structure. The proposed AC is
