ANAC CEL Theoretical Exam (Airframe Group) study plan

Map the airframe structural classifications and load paths, then explain in writing how each primary member carries tension, compression, shear, and bending

Identify the standard sheet-metal materials, tempers, and thickness designation conventions, and record the properties of each in a personal reference table

Describe the layout and purpose of fuselage, wing, and empennage structural members using correct terminology for each station and zone

Practice reading structural drawings and rivet callouts until you can state the fastener type, size, and spacing from a symbol alone

Explain the sequence of operations for laying out, cutting, forming, and fitting a sheet-metal repair, including bend allowance and setback calculations

Solve at least 10 bend allowance, setback, and rivet pitch problems by hand and verify each answer

Compare solid, blind, and special rivets and justify the selection for given joint configurations and access limits

Describe inspection criteria for cracks, corrosion, and fastener distress in sheet-metal structure and state when a repair becomes a major alteration

Complete a timed self-test on sheet-metal and structural topics and log every missed item by cause (knowledge gap, misread, or calculation error)

Diagram the major airframe systems (fuel, pressurization, ice and rain protection, oxygen) and trace the flow path through each

Explain how pressurization loads interact with fuselage structure and what inspection points follow from that interaction

Summarize the function and failure consequences of each system component in a structured comparison table

Explain the principles of AC and DC generation, rectification, and distribution as installed on transport-category aircraft

Trace a complete circuit from bus bar through protection devices to a load, and state the purpose of each protective element

Describe avionics bus architecture, redundancy, and the effect of a single bus failure on dispatch capability

Identify standard electrical symbols and wire identification markings and interpret them without reference material

Explain bonding, shielding, and grounding requirements and the inspection methods used to verify them

Classify aircraft hardware by type, thread standard, and grip length, and select correct fasteners for given applications

Identify the corrosion types most common in airframe structure and match each to its inspection and treatment method

Describe the approved methods of corrosion removal, surface preparation, and protective coating application

Explain the operation of primary and secondary flight controls and the rigging checks used to verify correct travel and adjustment

Describe hydraulic system layout, component function, and the procedures for servicing and bleeding a system

Trace landing gear extension, retraction, and indication circuits and identify the failure modes of each subsystem

Interpret rigging tolerances and control-surface travel limits and state the consequence of exceeding them

Describe the documentation chain for a maintenance action from work order through sign-off, and identify the records that must be retained

Explain the purpose and required content of maintenance records, release documents, and airworthiness documentation under Brazilian regulation

Outline the privileges and limitations of the certifying personnel categories relevant to the airframe group

Apply human-factors and safety-management concepts to a described maintenance error scenario and propose preventive actions

Take two full-length timed practice exams under test conditions and record raw and scaled scores for each domain

Analyze every missed item across both exams and rank the domains by error density

Re-study the two weakest domains using targeted drills rather than full-chapter review

Build a final one-page summary sheet of formulas, limits, and regulatory references for last-week review
