Airworthiness Directives; Boeing Model 767 Series Airplanes

AGENCY: Federal Aviation Administration, DOT.

ACTION: Final rule; correction.

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

SUMMARY: This document corrects information that appeared in 
airworthiness directive (AD) 96-14-05, amendment 39-9687, which was 
published in the Federal Register on July 9, 1996 (61 FR 35938). This 
AD is applicable to certain Boeing Model 767 series airplanes. Among 
other things, it supersedes a previously issued AD, requires 
inspections of the control rods of the outboard leading edge slat, and 
requires the installation of a modification that terminates the 
requirement for repetitive inspections. This action corrects the listed 
line numbers of airplanes subject to certain parts of the rule.

DATES: Effective August 13, 1996.
    The incorporation by reference of certain publications listed in 
the regulations was previously approved by the Director of the Federal 
Register as of August 13, 1996 (61 FR 35938, July 9, 1996).

FOR FURTHER INFORMATION CONTACT: Kristin Larson, Aerospace Engineer, 
Systems and Equipment Branch, ANM-130S, FAA, Seattle Aircraft 
Certification Office, 1601 Lind Avenue, SW., Renton, Washington; 
telephone (206) 227-1760; fax (206) 227-1181.

SUPPLEMENTARY INFORMATION: On June 27, 1996, the FAA issued AD 96-14-
05, amendment 39-9687; (61 FR 35938, July 9, 1996), which is applicable 
to certain Boeing Model 767 series airplanes and supersedes AD 90-20-
16, amendment 39-6726 (55 FR 37858, September 14, 1990). That AD 
requires a one-time visual inspection to determine the date of 
manufacture of the control rods of the outboard leading edge slat, and 
follow-on actions (i.e., repetitive ultrasonic inspection), if 
necessary. It also requires replacement of the control rod ends and 
attach bolts, for certain airplanes. For operators accomplishing the 
(follow-on) repetitive ultrasonic inspections, the AD requires the 
replacement of the control rod with a new control rod manufactured 
after June 1983; this replacement constitutes terminating action for 
the repetitive inspections.
    As published, paragraph (b) of AD 96-14-05 indicated that only 
certain airplanes were subject to its requirements. Those airplanes 
were specified as ones having line numbers ``1 through 264 inclusive, 
and 266 through 273 inclusive.'' However, due to a typographical error, 
the final number in this sequence of line numbers was incorrect: what 
was published as line number ``273,'' should have been line number 
``272.'' The airplane having line number 273 is not subject to the 
requirements of paragraph (b) of this AD.
    Action is taken herein to correct this typographical error in 
paragraph (b).
    Since no other part of the regulatory information has been changed, 
the final rule is not being republished.
    The effective date of the AD remains August 13, 1996.
    Accordingly, the final rule document (FR DOC. 96-16950), which was 
published on July 9, 1996, at 61 FR 35938, is corrected as follows:

39-6726, whichever occurs first, replace the control rod end and attach 
bolt with a new configuration control rod end and attach bolt on each 
wing, in accordance
