Airworthiness Directives; The Boeing Company Model 747-100, 747-
100B, 747-100B SUD, 747-200B, 747-200C, 747-200F, 747-300, 747SR, and 
747SP Series Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Final rule; correction.

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

SUMMARY: The FAA is correcting an airworthiness directive (AD) that 
published in the Federal Register. That AD applies to the products 
listed above. The reference to a ``sub-section number'' in paragraph 
(g) of the regulatory section is incorrect. This document corrects that 
error. In all other respects, the original document remains the same.

DATES: This final rule is effective May 25, 2011. The effective date 
for AD 2010-24-13 remains January 20, 2011.

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 (phone: 800-647-5527) is Document Management Facility, 
U.S. Department of Transportation, Docket Operations, M-30, West 
Building Ground Floor, Room W12-140, 1200 New Jersey Avenue, SE.,

SUPPLEMENTARY INFORMATION: Airworthiness Directive 2010-24-13, 
amendment 39-16532 (75 FR 78591,

[[Page 30254]]

December 16, 2010), currently requires adding two new indicator lights 
on a certain panel to inform the captain and first officer of a low 
pressure condition in the left and right override/jettison pumps of the 
center wing tanks. That AD also requires replacing the left and right 
override/jettison switches on the M154 fuel control module on the P4 
panel with improved switches and doing the associated wiring changes. 
That AD also requires, for certain airplanes, installation of a 
mounting bracket for the new indicator lights. In addition, that AD 
requires a revision to the maintenance program to incorporate 
airworthiness limitation No. 28-AWL-22. Additionally, that AD requires 
a revision to the airplane flight manual to advise the flightcrew what 
to do in the event that the pump low pressure light on the flight 
engineer's panel does not illuminate when the pump is selected off. 
That AD requires those actions for Model 747-100, 747-100B, 747-100B 
SUD, 747-200B, 747-200C, 747-200F, 747-300, 747SR, and 747SP series 
airplanes.
    As published, the reference to ``sub-section number is `28-60-06' 
'' in paragraph (g) of the regulatory section is incorrect. The correct 
sub-section number is 20-60-06.
    No other part of the preamble or regulatory information has been 
changed; therefore, only the changed portion of the final rule is being 
published in the Federal Register.
    The effective date of this AD remains January 20, 2011.

Correction of Regulatory Text

Sec.  39.13  [Corrected]

    In the Federal Register of December 16, 2010, on page 78593, in the 
second and third columns, paragraph (g) of AD 2010-24-13 is corrected 
to read as follows:
* * * * *
    (g) Within 36 months after the effective date of this AD: For 
airplanes with a P10 panel installed, add two new indicator lights 
on the P10 panel to inform the captain and first officer of a low 
pressure condition in the left and right override/jettison pumps of 
the center wing tanks, and, for airplanes that do not have the 
warning panel (P10 panel) installed, add a mounting bracket and two 
new indicator lights to the Autopilot Flight Director panel; and 
replace the left and right override/jettison switches on the M154 
fuel control module on the P4 panel with improved switches; and do 
the associated wiring changes. Accomplish these actions by doing all 
of the applicable actions specified in the Accomplishment 
Instructions of Boeing Service Bulletin 747-28A2288, Revision 1, 
dated January 21, 2010, except where that service bulletin states 
``20-60-00,'' the correct sub-section number is ``20-60-06,'' and 
except as described in Table 1 of this AD.
