Airworthiness Directives; Boeing Model 737-300, -400, and -500 
Series Airplanes Equipped With a Digital Transient Suppression Device 
(DTSD) Installed in Accordance With Supplemental Type Certificate (STC) 
ST00127BO

AGENCY: Federal Aviation Administration (FAA), Department of 
Transportation (DOT).

ACTION: Final rule; correction.

-----------------------------------------------------------------------

SUMMARY: The FAA is correcting information in an existing airworthiness 
directive (AD) that was published in the Federal Register on October 1, 
2009. The error resulted in use of an outdated division name and e-mail 
address in the vendor contact information. This AD applies to certain 
Boeing Model 737-300, -400, and -500 series airplanes. This AD requires 
revising the maintenance program to include new fuel system limitations 
for airplanes modified in accordance with STC ST00127BO. This AD also 
requires inspections and checks of the DTSDs and corrective actions, if 
necessary.

DATES: Effective November 5, 2009.

ADDRESSES: You may examine the AD docket on the Internet at http://www.regulations.gov; or in person at the Docket Management Facility 
between 9 a.m. and 5 p.m., Monday through Friday, except Federal 
holidays. The AD docket contains this AD, the regulatory evaluation, 
any comments received, and other information. The address for the 
Docket Office (telephone 800-647-5527) is the Document Management 
Facility, U.S. Department of Transportation, Docket Operations, M-30, 
West Building Ground Floor, Room W12-140, 1200 New Jersey Avenue SE., 
Washington, DC 20590.

FOR FURTHER INFORMATION CONTACT: Marc Ronell, Aerospace Engineer, ANE-

SUPPLEMENTARY INFORMATION: On September 18, 2009, the FAA issued AD 
2009-20-11, Amendment 39-16034 (74 FR 50683, October 1, 2009), for 
certain Boeing Model 737-300, -400, and -500 series airplanes. The AD 
requires revising the maintenance program to include new fuel system 
limitations for airplanes modified in accordance with Supplemental Type 
Certificate ST00127BO. This AD also requires inspections and checks of 
the digital transient suppression device and corrective actions, if 
necessary.
    As published, the vendor contact information specified in the 
Addresses section of the preamble and paragraph (n)(2) of the 
regulatory text of AD 2009-20-11 contained an outdated division name 
and e-mail address. Since that AD was published, the vendor has 
provided us with the recently updated contact information.
    No other part of the regulatory information has been changed; 
therefore, the final rule is not republished in the Federal Register.
    The effective date of this AD remains November 5, 2009.
