Study Notes
DAFI 21-101
- DAFI 21-101 outlines policies and procedures for aircraft and equipment maintenance management in the US Air Force.
- Ensures safe, reliable, and cost-effective maintenance for Air Force assets.
Maintenance Units
- An Aircraft Maintenance Unit (AMU) focuses on organizational-level maintenance for Air Force aircraft.
- An Equipment Maintenance Unit (EMU) handles organizational-level maintenance for non-aircraft equipment.
Maintenance Squadrons and Groups
- A Maintenance Squadron (MXS) coordinates maintenance activities within a maintenance group.
- A Maintenance Group (MXG) manages maintenance operations for a specific wing or organization.
Training and Management
- Maintenance Training Sections (MTS) create and deliver training for maintenance personnel.
- Unit Training Managers (UTM) oversee training and certification within their respective units.
Air Force Inspection System (AFIS)
- AFIS provides independent assessments of unit effectiveness, efficiency, economy, and readiness.
- Four inspection types: unit self-assessment, external evaluation, readiness evaluation, and compliance inspection.
Inspections
- Unit self-assessments are conducted by unit commanders and their staff.
- External evaluations offer an objective review of unit performance and efficiency and are carried out by higher headquarters, other services, or contractors.
Compliance and Effectiveness Inspections
- Unit Effectiveness Inspection (UEI) assesses mission accomplishment and standards compliance.
- Unit Compliance Inspection (UCI) focuses on regulatory compliance.
- Both types of inspections are managed by the Inspector General or authorized inspection bodies.
Inspector General System
- Promotes Air Force efficiency and readiness through independent evaluations of unit performance.
Operational Risk Management (ORM)
- ORM helps identify, assess, and manage risks to minimize potential mishaps.
- Five steps in the ORM process: identify hazards, assess risks, develop controls, implement controls, and supervise/evaluate.
Hazards, Risks, and Mishaps
- A hazard refers to conditions that could cause harm or damage.
- Risk denotes the chance of occurrence of an event and its potential consequences.
- A mishap is an unplanned event leading to injury, illness, or significant damage or loss.
Levels of ORM
- Level 1 involves all personnel, Level 2 requires specialized training, and Level 3 focuses on high-risk operations needing advanced training.
Risk Assessment Code (RAC)
- The RAC standardizes communication of risk levels associated with various hazards.
- Four categories include:
- Category I: Catastrophic
- Category II: Critical
- Category III: Moderate
- Category IV: Negligible
Controls
- Controls are measures taken to eliminate or mitigate hazards and their consequences.
Difference Between Hazard and Risk
- A hazard is a potential source of harm, whereas risk measures the likelihood and severity of harm arising from that hazard.
