- Airline Maintenance Program: Must detail maintenance and revision time intervals, specific operations to maintain airworthiness, and reference applicable maintenance manuals.
- ICAO Regulations: Recommendations are issued as "annexes" and "prescriptions." Interventions to verify proper operations are defined as "controls." Norms whose application is desirable are "recommendations."
- Company Organization: The "manuale d'impresa" defines how the company is organized and its privileges.
- Training Structure: Organized in three levels: 1) base maintenance, 2) theoretical concepts + base training, 3) familiarization + ramp, transit, and base line maintenance.
- Human Factor Training (Part 145): Aims to improve manager-maintainer relationships, enhance safety and quality in operations, and increase efficiency of equipment.
- Maintenance Records: Retention period for aircraft maintenance records is typically 5 years.
- CRS Signing Process: Requires basic training, experience, machine courses, LMA extension, MOE training, Part 145 company authorization, and typically 2 years of company experience.
- QTB (Quality Technical Book) Contents: Includes service admission certificates, aircraft weight, airworthiness prescriptions, component status, and reported incidents under the commander's responsibility.
- LMA Extension: Occurs after MOE training but before EASA Part 66 exams.
- Man Hours Plan: Demonstrates the ability to manage available space, inspect work, and allocate sufficient resources.
- Performance Variables (Part 145): Include consumption of spare parts/materials, human capabilities/limits affecting operational safety, and the percentage of certified staff.
- Maintenance Program for Authorization: Must specify minimum operations with manufacturer's deadlines and can include diverse operations or those performed by specific maintainer categories (A, B, C).
- Continuing Airworthiness (Reg. 2042/2003): Relates to Part M, Part 21, and CS.
- JAR-OPS 1 for COA Operators: Requires the company to collect service data, ensure maintenance according to Part 145, and possess a hangar.
- CRS Authorization: A certified staff member who completed a Part 66 course is authorized by the Part 145 company they work for.
- EASA Action Areas: Encompass aircraft design and parts, maintenance, operations, and personnel licenses.
- Remote Maintenance Authorization: For aircraft operating far from an approved maintenance base, a temporary authorization can be granted to the captain or onboard engineer if they have sufficient training.
- Subcontractor Management (Part 145): Uncertified subcontractors are managed through framework agreements between companies.
- Aircraft Maintenance: Its execution depends on the operator.
- Maintenance Manual Contents: Specifies the training program for certified staff, quality standards for Part 145 to obtain MOA, and material detailing required works and compliance with controls.

- Hangar for Check A: Not mandatory for a Check A.
- Certified Staff (License A): Can perform and certify simple rectifications of inconveniences without needing fault isolation procedures.

- Workcard Error: Misreading a workcard is considered a "mistake."
- Accident: An event leading to a malfunction that causes personal injury.
- Night Maintenance: Associated with a decrease in attention, particularly concentrated between 1 AM and 4 AM or after 12 hours.
- Mechanic Involvement: Knowing company specifics and new technologies helps prevent "complacency."
- Accident Data Report: Includes description, cause analysis, conclusions, and recommendations.
- Situational Awareness: A study revealed major incongruities in maintenance reports as wrong installations, omissions, and maintenance of wrong parts.
- Human Error Conception: Generally considered unintentional.
- Difficulty in Investigating Human Error: Characterized by the latency of errors committed during maintenance.
- Human Psyche Control Levels: Involve "mistake-slip-lapses" and "knowledge-based, rule-based, skill-based" levels.
- Dirty Dozen: Damaged tools are an example of an "active" error.
- Complacency Effect: Leads to decreased attention.
- Flight Shutdowns due to Maintenance Errors: Account for 20%-30%.
- Commission Error: Means performing an extra action.
- SHEL Model (E): Refers to "Environment."
- Correcting Dirty Dozen Factors: Achieved through training and new procedures.
- Mistakes (Definition): Cognitive errors caused by memory.
- Open Questions: Describe EASA regulatory structure (Reg. 216/2008) focusing on general requirements, EASA structure, and continuing airworthiness structure. Describe the SHELL model, including its meaning, blocks, and interfaces.
