The problem involves an \"integrator hook\" — a small but critical component that helps secure the off-wing escape slide compartment door. If this hook isn't working properly due to an incorrectly adjusted nut, the escape slide can deploy accidentally (when it shouldn't) or fail to deploy in an emergency (when it should).\n\n**Who must act:** Anyone operating Boeing 767 aircraft that have had Service Bulletin 767-25-0051 applied to them.\n\n**What action is required:** Operators must follow Boeing's Alert Service Bulletin 767-25A0104 Revision 2, which involves replacing the hook and reworking the integrator assembly.\n\n**Why it matters:** Emergency escape slides are life-critical safety equipment. An inadvertent deployment during flight or on the ground could injure people or damage the aircraft. A failure to deploy during an emergency evacuation could cost lives. This directive forces operators to fix the defect by a hard deadline (31 December 1989).\n\n**Key deadline:** The work had to be completed before 31 December 1989."},"flash_summary":{"complexity_score":2,"scope_assessment":{"changed":false,"description":"The text does not indicate any change in scope from a prior instrument.
