Airworthiness Directive · Amendment 39-16241 · Fuselage
The Boeing Company Model 767 Airplanes
This AD applies to The Boeing Company Model 767-200, -300, -300F, and -400ER series airplanes, certificated in any category, as identified in Boeing Alert Service Bulletin 767-53A0193, Revision 1, dated April 9, 2009.
We are adopting a new airworthiness directive (AD) for certain Model 767 series airplanes. This AD requires inspections for scribe lines in the fuselage skin at skin lap joints, the skin at certain external approved repairs, the skin around external features such as antennas, and the skin at decals; and related investigative and corrective actions if necessary. This AD results from reports of scribe lines found at skin lap joints and butt joints, around external repairs and antennas, and at locations where external decals had been cut. We are issuing this AD to detect and correct scribe lines, which can develop into fatigue cracks in the skin and cause sudden decompression of the airplane.
You are responsible for having the actions required by this AD performed within the compliance times specified, unless the actions have already been done.
At the applicable times specified in paragraph 1.E., “Compliance,” of Boeing Alert Service Bulletin 767-53A0193, Revision 1, dated April 9, 2009, except as provided in paragraph (h) of this AD, do detailed inspections for scribe lines of skin lap joints around external repairs and antennas, and at locations where external decals might have been cut. Do all applicable related investigative and corrective actions at the times specified in Boeing Alert Service Bulletin 767-53A0193, Revision 1, dated April 9, 2009, by accomplishing all actions specified in the Accomplishment Instructions of that service bulletin, except as provided by paragraph (i) of this AD.
Note 1: The inspection exemptions noted in paragraph 1.E. of Boeing Alert Service Bulletin 767-53A0193, Revision 1, dated April 9, 2009, apply to this AD.
Where Boeing Alert Service Bulletin 767-53A0193, Revision 1, dated April 9, 2009, specifies a compliance time after “the original issue date on this service bulletin,” this AD requires compliance within the specified compliance time after the effective date of this AD.
(i) Where Boeing Alert Service Bulletin 767-53A0193, Revision 1, dated April 9, 2009, specifies to contact Boeing for appropriate action, accomplish applicable actions before further flight using a method approved in accordance with the procedures specified in paragraph (l) of this AD.
At the applicable time specified in paragraph (j)(1) or (j)(2) of this AD: Submit a report of positive findings of scribe lines deeper than 0.001 inch along with a repair plan found during the inspections required by paragraph (g) of this AD. Operators may use the reporting form contained in Appendixes B and C, as applicable, of Boeing Alert Service Bulletin 767-53A0193, Revision 1, dated April 9, 2009. Send the report to Boeing Commercial Airplanes, P.O. Box 3707, Seattle, Washington 98124-2207. The report must contain, at a minimum, the inspection results, a description of any discrepancies found, the airplane serial number, and the number of flight cycles and flight hours on the airplane. Under the provisions of the Paperwork Reduction Act (44 U.S.C. 3501 et seq.), the Office of Management and Budget (OMB) has approved the information collection requirements contained in this AD and has assigned OMB Control Number 2120-0056.
(1) If the inspection was done on or after the effective date of this AD: Submit the report within 30 days after the inspection.
(2) If the inspection was done before the effective date of this AD: Submit the report within 30 days after the effective date of this AD.
