Federal Aviation Administration

14 CFR Part 39

[Docket No. FAA-2006-24173; Directorate Identifier 2005-NM-262-AD; 
Amendment 39-14652; AD 2006-12-26]
RIN 2120-AA64


Airworthiness Directives; Boeing Model 777-200, -300, and -300ER 
Series Airplanes

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

ACTION: Final rule; correction.

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

SUMMARY: The FAA is correcting a typographical error in an existing 
airworthiness directive (AD) that was published in the Federal Register 
on June 16, 2006 (71 FR 34808). The error resulted in a reference only 
to the left main fuel tank in paragraph (f)(2) of that AD rather than 
to both the left and right main fuel tanks. This AD applies to certain 
Boeing Model 777-200, -300, and -300ER series airplanes. This AD 
requires a one-time inspection of the first bonding jumper aft of the 
bulkhead fitting to detect damage or failure and to determine the 
mechanical integrity of its electrical bonding path, and repair if 
necessary; measurement of the bonding resistance between the fitting 
for the fuel feed tube and the front spar in the left and right main 
fuel tanks, and repairing the bonding if necessary; and application of 
additional sealant to completely cover the bulkhead fittings inside the 
fuel tanks.

DATES: Effective July 21, 2006.

ADDRESSES: The AD docket contains the proposed AD, comments, and any 
final disposition. You may examine the AD docket on the Internet at 
http://dms.dot.gov, or in person at the Docket Management Facility 
office between 9 a.m. and 5 p.m., Monday through Friday, except Federal 
holidays. The Docket Management Facility office (telephone (800) 647-
5227) is located on the plaza level of the Nassif Building at the U.S. 
Department of Transportation, 400 Seventh Street, SW., Room PL-401, 
Washington, DC. This docket number is FAA-2006-24173; the directorate 
identifier for this docket is 2005-NM-262-AD.

SUPPLEMENTARY INFORMATION: On June 8, 2006, the FAA issued AD 2006-12-
26, amendment 39-14652 (71 FR 34808, June 16, 2006), for certain Boeing 
Model 777-200, -300, and -300ER series airplanes. The AD requires a 
one-time inspection of the first bonding jumper aft of the bulkhead 
fitting to detect damage or failure and to determine the mechanical 
integrity of its electrical bonding path, and repair if necessary; 
measurement of the bonding resistance between the fitting for the fuel 
feed tube and the front spar in the left and right main fuel tanks, and 
repairing the bonding if necessary; and application of additional 
sealant to completely cover the bulkhead fittings inside the fuel 
tanks.
    As published, paragraph (f)(2) of that AD refers only to the left 
main fuel tank. The correct reference is ``left and right main fuel 
tanks.''
    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 July 21, 2006.


Sec.  39.13  [Corrected]

In the Federal Register of June 16, 2006, on page 34810, in the third 
column, paragraph (f)(2) of AD 2006-12-26 is corrected to read as 
follows:
* * * * *
    (2) Measure the bonding resistance between the fitting for the fuel 
feed tube and the front spar in the left and right main fuel tanks. If 
the bonding resistance exceeds 0.001 ohm: Before further flight, repair 
the bonding in accordance with the service bulletin.
