The inspection must follow the Accomplishment Instructions in Boeing Special Attention Service Bulletin (SASB) 767‑25‑0299.  \n\n- If an actuator cartridge with serial number in the range 5481–5741 (inclusive) is found, the operator must: remove the actuator (2(a)); inspect the cartridge for a required clearance hole and take corrective actions if the clearance hole is missing (2(b)) — corrective actions may include replacing the cartridge with a new one or a serviceable cartridge from a recharge kit; and reinstall the actuator (2(c)). These actions must follow the Boeing SASB (Requirement 2).  \n\n- From the effective date of the directive, it is prohibited to install on any aeroplane an actuator cartridge assembly (OEA part number 5262200) with serial number 5481–5741 that lacks a clearance hole between the two firing pins (Requirement 3).\n\n- Timing: the initial inspection (Requirement 1) must be done within two years of the directive taking effect; any corrective actions for affected cartridges (Requirement 2) must be completed before further flight; the installation prohibition (Requirement 3) is immediate.\n\n**Who this affects\n\n- Aircraft operators/owners of Boeing 767‑200 and 767‑300 aeroplanes equipped with off‑wing escape slides.  \n- Maintenance organisations and technicians who perform inspections, removals, replacements, and record keeping.  \n- Parts suppliers and overhaul shops that supply or refurbish OEA part number 5262200 cartridge assemblies, because certain serial‑numbered cartridges are barred from installation unless modified to include the clearance hole.\n\n**Why it matters (stated purpose and operational effect)\n\n- The stated safety purpose (in the AD background) is to correct an unsafe condition related to off‑wing slide door‑opening actuators. The AD makes the inspection and any necessary corrective action mandatory under aviation safety regulation.  \n\n**Practical implications, costs and incentives\n\n- Direct compliance costs fall on aircraft operators: labour for inspection, possible removal and replacement of actuator cartridges, downtime while work is done, and parts costs if cartridges require replacement. These are triggered for any affected aircraft that contain cartridges in the specified serial range (5481–5741). (See Requirement 1–2 and Compliance).  \n\n- Maintenance providers decide how to source replacement or serviceable cartridges; operators may prefer using serviceable components from recharge kits (per Requirement 2(b)) where available.  \n\n- The prohibition on installing OEA part number 5262200 cartridges lacking the clearance hole (Requirement 3) creates an effective constraint on use of existing stock of those parts; suppliers must either ensure the clearance hole is present or cease supplying those specific serials for installation.  \n\n- There is a modest operational‑risk and logistics effect: if parts with acceptable serials or modified cartridges are scarce, operators may face longer ground time for repairs or need to source alternatives.  \n\n**Implementation and enforcement notes\n\n- The AD makes compliance mandatory by regulatory order; it relies on Boeing SASB 767‑25‑0299 for the detailed inspection and corrective steps (Note 1). The SASB itself references an OEA service bulletin for cartridge inspection detail. Operators therefore must have access to and follow the referenced service instructions; the AD converts that guidance into a mandatory requirement.  \n\n- The AD sets a clear compliance schedule: inspection within two years, corrective actions before further flight, and immediate prohibition of installing non‑compliant cartridges (Compliance section).  \n\n**Trade‑offs, risks and unintended effects to watch for\n\n- Concentrated cost: only operators of affected 767 variants with off‑wing slides and whose actuators fall in the serial number range will bear replacement costs; for others the only cost is arranging and documenting the inspection within two years.  \n\n- Substitution effect: operators may substitute serviceable cartridges from recharge kits or different part numbers if compatible and approved.  \n\n- Administrative burden: recordkeeping and coordination with maintenance providers to ensure serial numbers are checked and any removed cartridges are correctly handled.  \n\n- Implementation risk: the AD depends on external service bulletins for detailed steps; if there are ambiguities in those documents, additional industry queries or service instructions may be necessary.  \n\n**References inside the AD**: Requirements 1–3 set out the mandatory steps; the Compliance section sets deadlines. The AD also references Boeing SASB 767‑25‑0299 (dated 18 January 2001) and OEA Service Bulletin 5262 (02) SB (NC) (Note 1), and cites FAA AD 2004‑16‑10 (Note 2) as related material."},"flash_summary_failed":{"failed":true,"reason":"A positive credit balance is required for all requests, including BYOK, so fallback providers remain available.
