| 2011-33544 | Airworthiness Directives; The Boeing Company Airplanes | Proposed Rule | We propose to adopt a new airworthiness directive (AD) for certain The Boeing Company Model 777-200 and -300 series airplanes. This proposed AD was prompted by reports of cracked retract actuator fuse pins that can fail earlier than the previously determined safe life limit of the pins. A fractured retract actuator fuse pin can cause the main landing gear (MLG) to extend without restriction and attempt to lock into position under high dynamic loads. This proposed AD would require an inspection for the part number of the fuse pin, and replacement of the pin if necessary. We are proposing this AD to prevent structural damage to the side and drag brace lock assemblies, which could result in landing gear collapse during touchdown, rollout, or taxi. | 2011-12-30 | 2011 | 12 | https://www.federalregister.gov/documents/2011/12/30/2011-33544/airworthiness-directives-the-boeing-company-airplanes | https://www.govinfo.gov/content/pkg/FR-2011-12-30/pdf/2011-33544.pdf | Transportation Department; Federal Aviation Administration | 492,159 | We propose to adopt a new airworthiness directive (AD) for certain The Boeing Company Model 777-200 and -300 series airplanes.
