(See Requirement 1–5.)\n- Until the modification work is completed, it mandates repetitive pre-flight and periodic inspections of door fit and specific fittings. (See Requirement 1 and Compliance.)\n- After completing the specified modifications (relocating the closed indication sensor, modifying the lock handle mechanism, and replacing two roller-fitting part numbers), the operator must update the Aircraft Maintenance Plan to add recurring operational/functional checks; completing those modifications ends the repetitive inspection requirement. (See Requirement 4–5 and Note 1.)\n\n**Who this affects**\n\n- Aircraft owners and operators of Embraer ERJ‑170 models listed in Applicability (ERJ 170‑100 LR/STD/SE/SU and ERJ 170‑200 LR/STD/SU). (Applicability.)\n- Maintenance organisations and certificated engineers who must perform the inspections, rework, replacements and maintenance-plan revisions. (Requirements 2–5.)\n- Parts suppliers that provide the specified roller fittings and any replacement components called up by the Embraer service bulletins. (Requirements 2.c and 4.b.)\n\n**Why it matters (stated purpose and operational effect)**\n\n- Stated purpose: the regulator received several reports of aircraft being dispatched and flown with a cargo door unlocked. The actions are intended to ensure cargo doors are checked, can be secured properly, and that indications of door-closed status are reliable so aircraft are not dispatched with an unsecured cargo door. (Background; Note 2.)\n\n**Key required actions and timing (mechanics in plain terms)**\n\n- Immediate/short-term actions:\n - Before each departure (until initial corrective actions are done) perform a visual check that forward and aft cargo doors are flush, latched and locked according to the aircraft’s Minimum Equipment List procedures. (Requirement 1; Compliance.)\n - Within 10 days of 23 March 2007 do the initial removal of the door surround trim lining cover plate and perform detailed visual inspections for interference and damage, following Embraer Alert Service Bulletin (ASB) 170‑52‑A036 and Service Bulletin (SB) 170‑50‑0006. If interference/damage is found, rework or replace parts before further flight; otherwise certain rework is still required within 150 flight cycles. (Requirement 2.a–c and Compliance timings.)\n- Repetitive inspections:\n - Repeat the inspection of lateral roller fittings at intervals not to exceed 150 flight cycles until terminating action is accomplished. (Requirement 3; Compliance.)\n- Modifications (terminating actions):\n - Within 5,000 flight cycles after 31 July 2008, relocate the cargo door closed indication sensor (SB 170‑52‑0041) and modify the lock handle plus replace two roller fittings (SB 170‑52‑0044). Completing these actions and then updating the Maintenance Plan to include specified AMM functional checks terminates the repetitive inspection requirement. (Requirement 4–5; Note 1; Compliance.)\n\n**Who pays, who decides, and what behaviour changes**\n\n- Operators pay: labour for inspections, downtime, any rework or part replacements, and administrative cost to revise the Maintenance Plan. (Requirements 2–5; Compliance.)\n- The regulator (Civil Aviation Safety Authority delegate, via this Airworthiness Directive) decides the mandatory actions and deadlines; the operator and maintenance organisation decide scheduling and resource allocation to comply. (Directive text and signature.)\n- Behaviour changes required: more frequent pre‑flight/periodic inspections until mods are done; carrying out specified rework/part replacement and AMM/maintenance‑plan updates; and continuing periodic operational checks thereafter. (Requirements and Compliance.)\n\n**Costs, incentives, trade‑offs and implementation risks (practical testing of the stated purpose)**\n\n- Direct costs: labour time for initial and repetitive inspections, parts cost for the new roller fittings and any bearings replaced, and aircraft downtime while work is done. (Requirements 2.c, 4.b, Compliance intervals.)\n- Concentrated vs diffuse effects: the costs fall directly on individual operators (diffuse across operators), while parts manufacturers or authorized service providers will receive the concentrated purchase/rework business. (Requirements calling for specific part numbers and service bulletins.)\n- Operational trade‑offs: short‑term increase in pre‑flight checks and maintenance activity reduces the risk of dispatching with an unsecured door; operators must schedule inspections and modifications so as not to unduly disrupt flight operations. (Requirement 1; Note 1.)\n- Supply/implementation risk: compliance depends on availability of approved parts (the SBs specify replacement part numbers) and on access to approved revisions of Embraer ASBs/SBs or later ANAC‑approved revisions. If parts or approved revisions are delayed, operators may face extended repetitive inspection burden. (Requirements reference Embraer SBs/ASBs and ANAC approvals.)\n- Regulatory certainty: the AD cross‑references Brazil’s ANAC AD and requires actions in accordance with Embraer service documents or later ANAC‑approved revisions; this creates dependency on external approvals and international coordination for later revisions. (Note 2 and multiple references to ANAC approved revisions.)\n\n**Implementation note**\n\n- Completing the modification package (Requirement 4) and updating the Maintenance Plan (Requirement 5) is explicitly identified as terminating action for the repetitive inspections described in Requirement 3 (Note 1). Operators should plan to complete the modification package within the calendar/flight‑cycle windows to avoid ongoing repetitive inspection costs.
