SUPPLEMENTARY INFORMATION: On September 18, 2009, the FAA issued AD

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

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regulatory text of AD 2009-20-11 contained an outdated division name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.
