9.6 Tasks: Aircraft Maintenance Engineering Vocabulary

Vocabulary flashcards focusing on physical work, task planning, repetitive task risks, visual inspection procedures, and simple vs. complex aircraft systems.

Job Cards (Task Sheets)

Documents detailing specific task instructions, task types (e.g., inspection, repair, overhaul), maintenance manual references, and part numbers.

Shift Supervisor

The role responsible for allocating sub-tasks, ensuring personnel have all required resources, or encouraging teams to manage their own workload.

Musculoskeletal System

The body system consisting of physical links (bones), joints, and muscles that exert motive force for all fine and gross movements.

Mechanical Advantage (Biomechanical)

The leverage and mechanical advantage provided by the relative positions of the load, muscle connections, and joints in a given posture.

Ergonomic Aircraft Design

Design practice utilizing computerized tools based on human performance data (body sizes, strengths, pivots) to ensure maintenance accessibility and ease of force application.

Complacency

A major hazard in repetitive tasks where extreme familiarity leads an engineer to skip steps, stop consulting manuals, or devote insufficient attention to checks.

Visual Inspection

The principal maintenance process using the eyes, sensory aids, and physical manipulation to examine and evaluate aircraft system or component airworthiness.

CAP 562 Leaflet H-60

UK Civil Aviation Authority (CAA) guidance covering engineer eyesight standards, routine vision checks, and recommendations on corrective lenses.

Non-destructive Visual Inspections with a Borescope

An optical inspection procedure using borescopes or magnifiers to visually inspect internal or hidden components without causing damage.

Non-Destructive Inspection (NDI)

Maintenance inspection methods incorporating visual search along with specialist equipment (e.g., eddy currents, FPI) to detect invisible internal or surface defects.

Fluorescent Penetrant Inspection (FPI)

A specialist Non-Destructive Inspection (NDI) technique used to reveal invisible surface-breaking flaws in aircraft components.

Simple System

An aircraft system whose purpose, composition, and function are transparent and easy for an engineer to understand, diagnose, and fault-find.

Complex System

An aircraft system featuring wide inputs, intricate modifications/responses, and distributed outputs, where an engineer knows the purpose but needs training to conceptualize composition and function.

Complex System Schematic

A technical diagram mapping out the intricate layout, components, switches, valves, and flow paths of a complex aircraft system (e.g., fuel system).

System-Specific Training

Specialized training required for maintaining complex systems, teaching engineers system operation, component breakdown, failure modes, and analytical troubleshooting.

Category B1 and B2 Engineers

Specialized mechanical and avionics engineers who must work collaboratively when maintaining complex systems that interface with cockpit controls and indications.
