FAA mandates replacement of insulation blankets on Boeing's freighter model

The Federal Aviation Administration (FAA) has issued a final rule airworthiness directive for the Boeing 767-300F, addressing potential fire smoke risks. The FAA determined that certain cargo compartment insulation blankets do not adequately fit some locations, allowing smoke to migrate past the cargo compartment sidewall liners and into the main cabin.

In its notice of proposed rulemaking, the FAA suggested replacing the insulation blankets as failure to address this issue could result in a fire in the bilge area of the cargo compartment and lead to a smoke and fire event in the passenger compartment. Operators of 32 affected 767F aircraft have until January 13, 2028, to replace these insulation blankets.

The Air Line Pilots Association, International supported the proposal without changes. However, Boeing, Aviation Partners Boeing (APB), and All Nippon Airways (ANA) commented on it. APB sought clarification on whether winglet installation affects compliance with the directive. The FAA confirmed it does not affect compliance.
