#  [Amended]

**AGENCY:**

Federal Aviation Administration (FAA), DOT.

**ACTION:**

Final rule, correcting amendments.

**SUMMARY:**

The Federal Aviation Administration (FAA) is correcting inadvertent errors that appeared in a previously-published final rule. That final rule amended FAA regulations that require operators and manufacturers of transport category airplanes to take steps that, in combination with other required actions, should greatly reduce the chances of a catastrophic fuel tank explosion. In that final rule, erroneous compliance dates were shown. This document changes those compliance dates accordingly. It also corrects other non-substantive errors that have come to our attention.

**DATES:**

Effective July 2, 2009.

**FOR FURTHER INFORMATION CONTACT:**

If you have technical questions about this action, contact Michael E. Dostert, FAA, Propulsion/Mechanical Systems Branch, ANM-112, Transport Airplane Directorate, Aircraft Certification Service, 1601 Lind Avenue, SW., Renton, Washington 98057-3356; telephone (425) 227-2132, facsimile (425) 227-1320; e-mail: *[email protected]* . Direct any legal questions to Doug Anderson, ANM-7, FAA, Office of Regional Counsel, 1601 Lind Avenue, SW., Renton, WA 98057-3356; telephone (425) 227-2166; facsimile (425) 227-1007, e-mail *[email protected].*

**SUPPLEMENTARY INFORMATION:**

**Background**

The Federal Aviation Administration (FAA) published a final rule, request for comments entitled “Reduction of Fuel Tank Flammability in Transport Category Airplanes” in the *Federal Register* on July 21, 2008 (73 FR 42444).

Recently, it was brought to our attention that the effective date shown in the document was inconsistent with the Congressional Review Act. This act specifies that, for major rules like this one, the effective date is no sooner than 60 days after publication or 60 days after submission to Congress, whichever occurs later. Since this rule was not received by the Government Accounting Office until October 27, 2008, the effective date of the rule per the Congressional Review Act is December 26, 2008, not September 19, 2008. Because compliance dates were calculated based on a September 19, 2008 effective date, those dates are incorrect. This document makes the appropriate amendatory changes necessary to reflect the new compliance dates. We also found some minor errors in §§ 121.1117, 125.509 and 129.117 and are correcting them in this document.

**List of Subjects**

Aircraft, Aviation safety, Continued airworthiness.
