Unsafe Condition
Fracture of the main landing gear (MLG) bogie beam pivot pin due to improper rework during manufacture or existing fractures, which could lead to loss of the MLG truck during takeoff or landing and consequent loss of control of the airplane.
AI-generated summary from the source AD text. Verify against the official source before acting.
Required Actions
Verify part and serial numbers of MLG bogie beam pivot pins; replace with new or overhauled pins if necessary; ultimately replace all pins with improved new pins. Perform repetitive lubrications and inspections of the pivot pin, with investigative and corrective actions as needed.

ACTION: Final rule. ––––––––––––––––––––––––––––––––––– SUMMARY: The FAA is adopting a new airworthiness directive (AD) for certain Boeing Model 767-200, -300, and -300F series airplanes. This AD requires verifying the part and serial numbers of certain main landing gear (MLG) bogie beam pivot pins; replacing those pivot pins with new or overhauled pivot pins if necessary; and ultimately replacing all pivot pins with new, improved pivot pins. This AD also requires repetitive lubrications and inspections of the pivot pin, and related investigative and corrective actions if necessary. This AD results from reports indicating that numerous fractures of the MLG bogie beam pivot pin have been found and that some pivot pins may have had improper rework during manufacture. We are issuing this AD to prevent fracture of the MLG bogie beam pivot pin, which could lead to possible loss of the MLG truck during takeoff or landing and consequent loss of control of the airplane. DATES: This AD becomes effective May 12, 2006. The Director of the Federal Register approved the incorporation by reference of certain publications listed in the AD as of May 12, 2006. ADDRESSES: You may examine the AD docket on the Internet at http://dms.dot.gov or in person at the Docket Management Facility, U.S. Department of Transportation, 400 Seventh Street, SW., Nassif Building, Room PL-401, Washington, DC. Contact Boeing Commercial Airplanes, P.O. Box 3707, Seattle, Washington 98124-2207, for service information identified in this AD. FOR FURTHER INFORMATION CONTACT: Candice Gerretsen, Aerospace Engineer, Airframe Branch, ANM-120S, Seattle Aircraft Certification Office, FAA, 1601 Lind Avenue, SW., Renton, Washington 98055-4056; telephone (425) 917-6428; fax (425) 917-6590. 2 SUPPLEMENTARY INFORMATION: Examining the Docket You may examine the AD docket on the Internet at http://dms.dot.gov or in person at the Docket Management Facility office between 9 a.m. and 5 p.m., Monday through Friday, except Federal holidays. The Docket Management Facility office (telephone (800) 647-5227) is located on the plaza level of the Nassif Building at the street address stated in the ADDRESSES section. Discussion The FAA issued a supplemental notice of proposed rulemaking (SNPRM) to amend 14 CFR part 39 to include an AD that would apply to certain Boeing Model 767-200, -300, and -300F series airplanes. That SNPRM was published in the Federal Register on November 9, 2005 (70 FR 67939). That SNPRM proposed to require verifying the part and serial numbers of certain main landing gear (MLG) bogie beam pivot pins; replacing those pivot pins with new or overhauled pivot pins if necessary; and ultimately replacing all pivot pins with new, improved pivot pins. That SNPRM also proposed to require repetitive lubrications and inspections of the pivot pin, and related investigative and corrective actions if necessary. Comments We provided the public the opportunity to participate in the development of this AD. We have considered the comments received. Request To Revise Paragraph (h) The Boeing Company requests that the word ''inspection'' in the last sentence of paragraph (h) of the SNPRM be removed. Boeing notes that there are no inspection requirements in paragraph (h). We agree. Paragraph (h) contains special lubrication requirements and no inspection requirements. Therefore, we have changed the final rule to clarify that doing the actions in paragraph (j) of the AD terminates the special lubrication requirements of paragraph (h), rather than the inspection requirements. Request for New Interim Action The Air Transport Association (ATA), on behalf of American Airlines, does not object to the proposed lubrication and terminating modification, but does not believe any of the three proposed inspection options are viable. ATA and American recommend that the FAA and the manufacturer develop a practical and effective interim action because the daily pin measurements are impractical to perform. ATA and American state that these measurements require accurate and unique tools, and they are also physically awkward. In addition, ATA and American believe that the second proposed option (the ultrasonic inspections) require unique tools and may provide faulty readings due to the stamped part number on the pin. ATA and American believe that these two options for inspections may lead to unnecessary flight cancellation. ATA and American also state that the third option (the detailed inspection) requires pin removal, and there is no value added in removing and reinstalling the old pin. American believes that airlines would prefer to replace the pins at the time of inspection, which may cause an industry shortage of pins. We partially agree. We agree that ATA and American Airlines have valid concerns, and we recognize that the proposed inspections may not be suitable for each operator. For that reason we carefully considered a variety of inspection methods with varying levels of reliability and
