Airworthiness Directives; Boeing Model 737-100, -200, -200C, -
300, -400, and -500 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 May 22, 2007 (72 FR 28597). The error resulted in a confusing 
compliance time. This AD applies to all Boeing Model 737-100, -200, -
200C, -300, -400, and -500 series airplanes. This AD requires 
repetitive detailed inspections for damage of the electrical wire and 
sleeve that run to the fuel boost pump through a conduit in the fuel 
tank, and arcing damage of the conduit and signs of fuel leakage into 
the conduit; replacement of the sleeve with a new, smaller-diameter 
sleeve; and related investigative and corrective actions, as 
applicable.

DATES: Effective June 6, 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-
2007-28253; the directorate identifier for this docket is 2007-NM-031-
AD.

SUPPLEMENTARY INFORMATION: On May 2, 2007, the FAA issued AD 2007-11-
07, amendment 39-15064 (72 FR 28597, May 22, 2007), for all Boeing 
Model 737-100, -200, -200C, -300, -400, and -500 series airplanes. The 
AD requires repetitive detailed inspections for damage of the 
electrical wire and sleeve that run to the fuel boost pump through a 
conduit in the fuel tank, and arcing damage of the conduit and signs of 
fuel leakage into the conduit; replacement of the sleeve with a new, 
smaller-diameter sleeve; and related investigative and corrective 
actions, as applicable.
    As published, paragraph (k) of AD 2007-11-07 reads ``* * * 
Thereafter, repeat the detailed inspection at intervals not to exceed 
15,000 flight cycles. * * *'' The correct term, ``flight hours'' (not 
flight cycles), appears in all other compliance times cited in the AD, 
as intended.
    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 June 6, 2007.


Sec.  39.13  [Corrected]

0
In the Federal Register of May 22, 2007, on page 28600, in the third 
column, paragraph (k) of AD 2007-11-07 is corrected to read as follows:
* * * * *
    (k) At the applicable time specified by paragraph (k)(1) or 
(k)(2) of this AD: Do a detailed inspection for damage of the sleeve 
and electrical wire of the fuel boost pump; and, before further 
flight, install a new, smaller-diameter sleeve, and do related 
investigative and corrective actions, as applicable; in accordance 
with the Accomplishment Instructions of Boeing Alert Service 
Bulletin 737-28A1263, Revision 1, dated March 19, 2007. Thereafter, 
repeat the detailed inspection at intervals not to exceed 15,000 
flight hours. Accomplishment of the initial inspection, applicable 
corrective actions, and sleeve installation required by this 
paragraph terminates the requirements of paragraphs (f), (g), (h), 
and (i) of this AD.
