Step 0 , Read the instrument and note dates: AD/EMB-145/1 is effective 20 June 2008. The Directive requires that Requirements 1 and 2 be satisfied "Within 30 days after the effective date of this Directive or prior to the issue of a certificate of airworthiness, whichever occurs later." That means the operator must complete the applicability determination and any outstanding actions promptly and be able to demonstrate compliance to certifying authorities.
Step 1 , Assemble the records and stakeholders: Gather the aeroplane’s maintenance records, logbooks, modification and equipment fitment records, STC records, and previous AD compliance entries. Identify the continuing airworthiness manager, certifying staff and the maintenance organisations or certificated engineers authorised to perform the technical work for the relevant systems (avionics, hydraulics, structure, engines/APU, landing gear).
Step 2 , Obtain the full State of Design AD texts: Use the ANAC/DAC AD list provided in Table 1 as the checklist and obtain the full text of each listed ANAC/DAC AD. The Directive provides a URL: "http://www.anac.gov.br/certificacao/da/DAE.asp." Where that link is out of date, contact Embraer, the manufacturer’s continuing airworthiness organisation, or ANAC directly to obtain the authoritative AD text and any referenced service bulletins or manufacturer instructions. Make sure to retrieve the exact revision identified in Table 1 (for example R1, R2, R3 or E‑prefixed entries).
Step 3 , Perform an applicability analysis (requirement 1): For each ANAC/DAC AD listed in Table 1, compare its applicability criteria (serial number ranges, equipment part numbers, kit or mod status, installation of specific systems such as Honeywell Primus 1000) to the aircraft’s configuration and modification history. The Directive acknowledges that "not all the ADs listed in Table 1 will be applicable to all EMB-145 series aeroplanes," so document the basis on which you accept or reject applicability for each AD , e.g., serial number outside of scope, equipment not installed, modification previously approved and embodied, or AD previously complied with.
Step 4 , Check prior compliance evidence: For any State of Design AD that appears applicable, search the maintenance records to confirm whether the actions required by that AD were previously accomplished. The CASA Directive is explicit: the remedial duty is conditional on the AD being "applicable and has not been previously accomplished." Where prior compliance exists, retain documentary evidence (logbook entries, engineering order completion, modification records, or maintenance release) to demonstrate that work was done to the required standard and date.
Step 5 , Plan and execute remedial work where required (requirement 2): For any applicable AD not already accomplished, plan the technical action exactly as the State of Design AD specifies. This may involve embodying a modification, replacing parts, performing non‑destructive inspections, updating software (EICAS/FADEC/EICAS versions), or other corrective measures. Use appropriately certificated maintenance organisations and ensure the work is carried out to the standards and methods referenced in the State of Design AD (for example specified service bulletins, illustrated parts catalogues, approved data). Obtain any necessary approvals or data from Embraer or the State of Design if the ANAC/DAC AD references particular service information.
Step 6 , Certification and documentation: On completion of each required action, record compliance in the aircraft’s maintenance records and provide the necessary maintenance release or certificate of release to service. For actions completed prior to the Directive’s effective date, ensure records demonstrate complete conformity with the State of Design AD. For actions completed after the Directive’s effective date, ensure entries show the AD number and revision, the action performed, the method and data used, parts installed (including part numbers and serial numbers), and the signatures or endorsements required by Australian certification practices.
Step 7 , Provide evidence for certificate of airworthiness issuance: If the aircraft is undergoing initial certification or registration, present the documented applicability determinations and evidence of completed AD actions to the certifying authority. Because the Directive ties the compliance window to the issue of a certificate of airworthiness, certifying staff may require confirmation that all applicable items from Table 1 have been addressed.
Step 8 , Maintain an audit trail: Keep a consolidated compliance checklist aligned to Table 1 that indicates, for each ANAC/DAC AD listed, (a) whether it is applicable to the specific aeroplane, (b) whether it was previously accomplished and by what record, (c) actions performed to comply with the AD if required, and (d) location of supporting documents. This makes future audits and inspections faster and reduces the risk of repeated work.
Step 9 , Engage CASA if there are exceptional circumstances: The Directive does not itself provide an extension mechanism; if practical constraints prevent completing required actions in the timeframe, operators should contact CASA early to advise of the situation and to seek any administrative relief or guidance through CASA’s usual channels. Although the AD does not specify the procedural path for relief, early engagement is a standard risk‑mitigation step.
Step 10 , Monitor for related ADs and updates: The AD imports a snapshot list of ANAC/DAC ADs as at the time of issuance. Operators should continue to monitor CASA publications and State of Design (ANAC) updates for any later ADs, revisions or additional CASA directives affecting EMB-145 series aeroplanes, because those may impose further actions or modify compliance expectations.
In short: the operator must obtain the ANAC/DAC AD texts listed in Table 1, conduct a configuration‑specific applicability analysis, verify prior compliance, carry out any outstanding one‑time corrective actions using appropriate certificated maintenance providers, and document the results in the aircraft records so that compliance can be demonstrated to CASA and to certifying authorities prior to or in the course of issuing a certificate of airworthiness.
