7/10 complexity

This Airworthiness Directive requires operators of GE CF6-80A, CF6-80C2 and CF6-80E1 engines to amend the Airworthiness Limitations Section and approved maintenance programs to add mandatory inspections of specified life‑limited rotating parts and to carry out those inspections in accordance with the engine manual. It defines a "piece‑part opportunity" criterion and sets compliance timing. The rule affects aircraft operators and MROs who will organise, perform and pay for added inspections and program changes.

What it does

This instrument is an airworthiness directive (AD) titled AD/CF6/71 (4/2009) that imposes mandatory inspection and documentation changes for General Electric CF6-80A, CF6-80C2, and CF6-80E1 series turbofan engines. Mechanically, the AD requires two discrete actions.

First (Requirement 1), operators and owners must revise the Airworthiness Limitations Section (ALS) of the manufacturer’s Instructions for Continued Airworthiness (ICA), and, for air carrier operations, revise the approved continuous airworthiness maintenance programme to add a new heading “MANDATORY INSPECTIONS” and the inspection items set out in Table 1 of the AD. The AD states this in plain terms: "Revise the Airworthiness Limitations Section (ALS) of the manufacturer's Instructions for Continued Airworthiness (ICA), and for air carrier operations revise the approved continuous airworthiness maintenance program, by adding the following: 'MANDATORY INSPECTIONS' as detailed in Table 1 of this AD." The AD becomes effective 9 April 2009 and sets a compliance deadline for Requirement 1 of within 180 days after the AD’s effective date.

Second (Requirement 2), the AD mandates performance of the specified inspections in Table 1 “in accordance with the instructions provided in the applicable manual provisions.” The AD also defines the recurring inspection trigger point for many items as “each piece‑part opportunity” and provides a definition of piece‑part opportunity comprising two elements: a) the part is considered completely disassembled when accomplished in accordance with disassembly instructions in the manufacturer's engine manual; and b) the part has accumulated more than 100 cycles‑in‑service since the last piece‑part opportunity inspection, provided the part was not damaged or removed for cause (Definition paragraphs a and b).

Table 1 is extensive. It lists numerous life‑limited rotating parts (fan rotor disks, fan shafts, HPC and HPT rotors and spools, LPT rotor disks and shafts, rotating seals, etc.), identifies the part nomenclature and part numbers (where relevant), and prescribes a specific type of non‑destructive inspection (NDT) and the engine manual inspection chapter, task, subtask or paragraph to be used (for example, fluorescent‑penetrant inspection, eddy current inspection, magnetic particle inspection). Some table entries are flagged with a single asterisk (*) indicating parts added to the table by this AD, and others with a double asterisk (**) indicating updated Engine Manual Inspection Task/Sub Task references.

	Note 2: FAA AD 2009-04-10 Amdt 39-15816 dated 5 February 2009 refers.Note 3: This AD supersedes AD/CF6/46.
Compliance:	Fro Requirement 1 - Within 180 days after the effective date of this AD.For Requirement 2 - At each piece-part opportunity after Requirement 1 of this AD is completed.
	This Airworthiness Directive becomes effective on 9 April 2009.
Background:	This AD is superseding an existing airworthiness directive (AD) for General Electric Company (GE) CF6-80A, CF6-80C2, and CF6-80E1 series turbofan engines. That AD required revisions to the Airworthiness Limitations Section (ALS) of the manufacturer's Instructions for Continued Airworthiness (ICA) to include required inspection of selected critical life-limited parts at each piece-part exposure.This AD requires revisions to the CF6-80A, CF6-80C2, and CF6-80E1 series engines ALS sections of the manufacturer's manuals and an air carrier's approved continuous airworthiness maintenance program to incorporate additional inspection requirements, and to update certain Engine Manual Inspection Task and Sub Task Number references.This AD results from the need to require enhanced inspection of selected critical life-limited parts of CF6-80A, CF6-80C2, and CF6-80E1 series engines. The issuing of this AD is intended to prevent critical life-limited rotating engine part failure, which could result in an uncontained engine failure and damage to the aeroplane.

This section describes concrete steps an operator, air carrier, maintenance organisation or maintenance planner should follow, grounded in the AD text.

Identify applicability and affected fleet

Confirm whether your aircraft have CF6‑80A, CF6‑80C2 or CF6‑80E1 series engines, per the AD’s Applicability paragraph and Note 1. Note 1 lists common airframes where these engines are installed (Airbus A300/A310/A330, Boeing 747/767, MD‑11) but the AD applicability is to the engine series irrespective of airframe.

Document review and ALS/maintenance programme revision (Requirement 1)

Within 180 days of the AD’s effective date (the AD states “Within 180 days after the effective date of this AD”), revise the Airworthiness Limitations Section (ALS) of the manufacturer’s Instructions for Continued Airworthiness (ICA) to add the heading "MANDATORY INSPECTIONS" and to incorporate the inspection items from Table 1. For air carriers, revise the approved continuous airworthiness maintenance programme accordingly. The AD’s Requirement 1 mandates those revisions.
Ensure the ALS entries map each table row (part nomenclature, part number where listed, and inspection task reference) to the engine manual task/subtask and NDT method specified in Table 1. Pay special attention to entries flagged with a single asterisk (new parts added) and double asterisks (updated task/subtask references).
Submit the revised ALS and, for carriers, the revised maintenance programme to the appropriate CASA approvals process, following the usual change approval procedures applicable to the operator. The AD requires the revisions but does not detail the approval route; ensure acceptance/approval in accordance with regulatory processes for maintenance programme changes.

Carry out initial inspections (Requirement 2 sequencing)

After the ALS and maintenance programme have been revised in accordance with Requirement 1, perform the inspections listed in Table 1 "in accordance with the instructions provided in the applicable manual provisions." That is the AD’s Requirement 2.
For components scheduled to be inspected at the next piece‑part opportunity, confirm that the shop visits constitute a “piece‑part opportunity” per the AD’s Definition paragraphs: the part is completely disassembled per the engine manual and has accumulated more than 100 cycles‑in‑service since the last such inspection (unless removed for cause). If both elements are satisfied, the inspection must be performed at that piece‑part opportunity.

Ensure NDT competence and capability

The Table 1 entries prescribe specific inspection techniques (fluorescent‑penetrant, eddy current, magnetic particle, vent hole eddy current, etc.) and reference precise engine manual tasks/subtasks/paragraphs. Ensure that the maintenance organisation performing the work has the equipment, certification and staff competence to perform the specified tasks in accordance with the engine manual procedures.
If relying on external NDT providers, ensure contractual and technical arrangements require adherence to the referenced engine manual task/subtask procedures. Maintain written evidence of the inspection method used, the task reference applied, and the personnel who performed the inspection.

Recordkeeping and traceability

Maintain records showing the ALS revision (including date and approval), the maintenance programme revision, and evidence that the Table 1 inspections were performed in accordance with the referenced engine manual tasks and at the prescribed triggers. Record cycles‑in‑service and dates to demonstrate that the >100 cycles threshold or removal for cause has been properly applied when determining piece‑part opportunities.
Where an inspection reveals a defect, follow the corrective action and disposition instructions in the engine manual; keep records of any repairs, removals, or part condemnations.

Address parts and configuration-specific items

For parts marked with an asterisk (*) in the table, which the AD describes as parts added to the table, ensure these are added to ALS entries and included in the programme’s scope. For items marked with two asterisks (**), update the task/subtask reference as specified in the AD.
For engines configured with the R88DT turbine, use the configuration‑specific task references in Table 1 where applicable.

AMOC considerations

If you have an AMOC previously approved under FAA AD 2002‑07‑12, the AD states those AMOCs are approved for this AD as well. Review the AMOC’s scope and conditions to confirm that it aligns with the Table 1 items and the updated references in this AD.
If your inspection methodology differs from the AD and no prior FAA AMOC applies, consult CASA’s AMOC process (not specified in the AD text) to seek approval for an alternative method of compliance. Note the AD does not itself define the AMOC process steps; coordinate with CASA.

Maintenance planning

Incorporate the AD’s inspection triggers into the scheduled maintenance plan and shop visit scheduling. Use the engine manual disassembly definitions to determine which shop visits are “piece‑part opportunities,” and plan for the prescribed NDT during those visits.
Ensure sufficient lead time for engines entering overhaul or disassembly so that the mandatory inspections can be performed without causing unexpected delays. Where special NDT or tooling is required, ensure availability.

Communicate changes across the supply chain

Inform lessors, insurers, lessees and maintenance providers of ALS changes and the new mandatory inspections so that responsibilities and costs are transparent. Operators should ensure that third‑party shops have copies of the relevant engine manual task references and ALS provisions.

Audit and compliance monitoring

Although the AD does not specify CASA’s enforcement steps, prepare to demonstrate compliance through records and by ensuring the revised ALS and maintenance programme are on file and used in practice. Be ready to show that inspections were done per the engine manual tasks at the defined piece‑part opportunities.

Follow‑up points

If uncertainties arise about interpretation (for example, whether a given disassembly meets the engine manual’s “completely disassembled” standard), obtain a formal clarification from the engine manufacturer or from CASA to avoid contention in compliance audits.
Where the operator has existing FAA AMOCs, verify that the AMOC’s conditions are current and applicable to the updated task numbers and to any parts newly added by this AD.

By following these steps grounded in the AD text , revise the ALS and carrier programme within 180 days, schedule inspections at piece‑part opportunities per the AD’s definition, use the specified NDT and engine manual task references, and maintain documentary evidence , an operator can document compliance with AD/CF6/71 as written.
