Airworthiness Directives; Boeing Model 747 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 July 30, 2007 (72 FR 41438). The error resulted in certain 
compliance times being mislabeled as units of flight cycles instead of 
flight hours. This AD applies to all Boeing Model 747 airplanes. This 
AD requires an inspection of the No. 2 and No. 3 windows on the left 
and right sides of the airplane to determine their part numbers, and 
related investigative and corrective actions if necessary.

DATES: Effective September 21, 2007.

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 Operations office 

between 9 a.m. and 5 p.m., Monday through Friday, except Federal 
holidays. The Docket Operations office (telephone (800) 647-5527) is 
located on the ground level of the West Building at the DOT street 
address stated in the ADDRESSES section. This docket number is FAA-
2006-26441; the directorate identifier for this docket is 2006-NM-204-
AD.

SUPPLEMENTARY INFORMATION: On July 18, 2007, the FAA issued AD 2007-15-
10, amendment 39-15139 (72 FR 41438, July 30, 2007), for all Boeing 
Model 747-100, 747-100B, 747-100B SUD, 747-200B, 747-200C, 747-200F, 
747-300, 747-400, 747-400D, 747-400F, 747SR, and 747SP series 
airplanes. The AD requires an inspection of the No. 2 and No. 3 windows 
on the left and right sides of the airplane to determine their part 
numbers, and related investigative and corrective actions if necessary.
    As published, the compliance times in paragraph (g) of AD 2007-15-
10 were mislabeled as units of flight cycles instead of flight hours.
    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 September 4, 2007.

In the Federal Register of July 30, 2007, on page 41441, in the 2nd 
column, paragraph (g) of AD 2007-15-10 is corrected to read as follows:
* * * * *
    (g) Where Tables 1, 2, and 3 of paragraph 1.E. of Boeing Alert 
Service Bulletin 747-56A2012, dated August 24, 2006, specify counting 
the compliance time from ``* * * after the date on this service 
bulletin,'' this AD requires counting the compliance time from the 
effective date of this AD. After replacing a discrepant window with a 
new window, do the initial detailed inspection of the new window at the 
applicable compliance time: (1) within 5,500 flight hours after 
installing part number (P/N) 65B27042-( ) or 65B27043-( ), or (2) 
within 22,000 flight hours after installing P/N 65B27046-( ) or
