Airworthiness directives, Boeing Model 767: Airworthiness Directives; Boeing Model 767 Airplanes, Federal Register, August 21, 2007, Volume 72, Number 161, Rules and Regulations, Page 46545, 14 CFR Part 39, Docket No. FAA-2006-24952, Directorate Identifier 2006-NM-107-AD, Amendment 39-15157, AD 2007-16-18, RIN 2120-AA64, Final rule.

(This airworthiness directive (AD) is effective September 25, 2007. The Director of the Federal Register approves the incorporation by reference of certain publications listed in the AD as of September 25, 2007.)

PURPOSE: This airworthiness directive (AD) results from a fire in the forward lower lobe cargo compartment in certain Boeing Model 767 airplanes found shortly after airplane arrival. This AD requires actions intended to detect and correct damage to wires in the forward and aft lower lobe cargo compartments, which could result in a potential short circuit and consequent fire in the forward and aft lower lobe cargo compartments.

SUMMARY: The Federal Aviation Administration (FAA) adopts a new AD for all Boeing Model 767 airplanes. This AD requires repetitive detailed inspections of the wire bundles, power drive unit (PDU) wiring, and wire attaching hardware, supports, and sleeving located in the forward and aft lower lobe cargo compartments, and corrective actions as necessary.

(This airworthiness directive (AD) remains effective June 6, 2007.)

PURPOSE: This airworthiness directive (AD) corrects an error regarding a confusing compliance time.

SUMMARY: The Federal Aviation Administration (FAA) corrects a typographical error in an existing AD that was published in the Federal Register on May 22, 2007 (72 FR 28597). This AD applies to all Boeing Model 737-100, -200, -200C, -300, -400, and -500 series airplanes, and 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.

NEED FOR CORRECTION: 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 is “flight hours” (not flight cycles), which appears in all other compliance times cited in the AD, as intended.

CORRECTION: 14 CFR Part 39, Section 39.13 is corrected as follows:

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.
