2020-17362: Airworthiness Directives; The Boeing Company Airplanes

Summary

The FAA proposes to supersede Airworthiness Directive (AD) 2016-25-29, which applies to certain The Boeing Company Model 767-200 and -300 series airplanes. AD 2016-25-29 requires replacing the cargo compartment insulation blankets on the left and right sides with new insulation blankets that incorporate fire stops. Since the FAA issued AD 2016-25-29, it was determined that an incorrect part number was specified for certain insulation blankets, and the FAA has determined that additional insulation blankets need to be replaced and that additional airplanes are subject to the unsafe condition. This proposed AD would continue to require the actions in AD 2016-25-29 for certain airplanes. This proposed AD would also add airplanes to the applicability and would require a general visual inspection of the replacement insulation blankets to determine if the blankets are in serviceable condition and correctly installed, and applicable on- condition actions. For certain airplanes, this AD would also require an inspection to determine the insulation blanket part number installed; replacement of additional insulation blankets; and applicable on- condition actions. The FAA is proposing this AD to address the unsafe condition on these products.
