Airframe Metallic Structures
Airframe metallic-structure questions test sheet metal inspection, defects, rivets, fasteners, welding, heat treatment, repair layout, and structural safety.
How to study FAA Airframe
Build each answer around approved maintenance data: identify the structure or system, control stored energy and contamination, inspect before replacing, document discrepancies, and never return an aircraft to service on an assumption.
Core concepts
Concept 1
Airframe Metallic Structures questions reward the answer that follows the official rule source, safety duty, and practical work sequence.
Exam cue: Identify the system, hazard, tool, code rule, or licensing duty being tested.
Concept 2
The strongest answer controls the hazard before continuing work, testing equipment, or documenting completion.
Exam cue: Check inspection, isolation, measurement, documentation, and environmental requirements.
Concept 3
Eliminate answers that ignore inspection, code clearance, environmental controls, lockout, labeling, or qualification limits.
Exam cue: Choose the safe compliant answer before the fastest production answer.
Risk pitfalls and guardrails
Treating local, state, and federal rules as interchangeable.
Guardrail: Avoid answers that skip inspection, ignore the code source, energize unsafe equipment, vent regulated material, or treat local rules as optional.
Skipping required inspection, isolation, documentation, or recovery steps.
Guardrail: Avoid answers that skip inspection, ignore the code source, energize unsafe equipment, vent regulated material, or treat local rules as optional.
Choosing a convenient answer that exceeds the worker's qualification or equipment rating.
Guardrail: Avoid answers that skip inspection, ignore the code source, energize unsafe equipment, vent regulated material, or treat local rules as optional.
Memory anchors
Metal Inspection
Metal structures must be inspected for cracks, corrosion, distortion, loose fasteners, and hidden damage.
Sheet Defects
Sheet metal defects include cracks, scratches, dents, elongation, corrosion, and improper hole condition.
Repair Material
Repair material must match approved data, alloy, temper, thickness, and structural purpose.
Rivet Layout
Rivet pitch, edge distance, diameter, and pattern must preserve strength and avoid new stress concentration.
Rivet Removal
Rivet removal should protect the hole and surrounding structure from enlargement or gouging.
Blind Fastener
Blind fasteners are used only where approved and installed with the correct grip and tool.
Heat Treatment
Aluminum heat treatment changes strength and must follow approved process and identification requirements.
Welding Safety
Welding requires correct gas, filler, shielding, ventilation, fire protection, and material compatibility.
SRM Data
Structural repairs must use the aircraft structural repair manual or other approved data.
PPE Sheet Metal
Cutting, drilling, and riveting require eye, hand, hearing, and chip-control precautions.
Checkpoint rule
Do the check-up only after you can summarize each concept in one sentence and identify one dangerous pitfall from memory.
