Airworthiness Directive · Amendment 39-18755 · Equipment/furnishings
The Boeing Company Airplanes
Superseded. A later AD replaced this one: AD 2021-12-11. Comply with the one in force.
This AD applies to The Boeing Company Model 767-200 and -300 series airplanes, certificated in any category, as identified in Boeing Special Attention Service Bulletin 767-25-0550, dated January 30, 2015.
We are adopting a new airworthiness directive (AD) for certain The Boeing Company Model 767-200 and -300 series airplanes. This AD was prompted by a report of a fire in the bilge area of the cargo compartment that burned through the insulation blankets that were intended to prevent smoke from migrating behind the cargo compartment sidewall liners and upward into the main cabin. This AD requires replacing the cargo compartment insulation blankets on the left and right sides with new insulation blankets that incorporate fire stops. We are issuing this AD to address the unsafe condition on these products.
Within 36 months after the effective date of this AD: Replace the cargo compartment insulation blankets on the left and right sides between stringers 29 and 33 with new insulation blankets that incorporate fire stops, in accordance with the Accomplishment Instructions of Boeing Special Attention Service Bulletin 767-25-0550, dated January 30, 2015. For Groups 1 through 4, Configurations 1 and 2, airplanes identified in Boeing Special Attention Service Bulletin 767-25-0550, dated January 30, 2015, no action is required by this AD.
