Next, We present a brief but essential glossary, highlighting terms such as ADD y DDG, fundamental for the work in the hangar or on the track.
1. ADD (DEFORRED defect or deferred action)
In aviation, Not all defects of an aircraft must be repaired immediately. When a problem does not compromise flight safety, It is documented as a ADD, allowing the aircraft to continue operating under certain conditions until it can be solved.
Practical example:
A defective interior lighting system could be classified as an ADD, as long as it does not affect the visibility or critical functioning of the plane.
2. DDG (Dispatch Deviation Guide)
He DDG It is an essential document for technicians and crews, since it specifies the conditions under which an aircraft can be dispatched with inoperative equipment. It is a key tool to ensure that flights can operate safely, Even if there are minor failures.
In practice:
If a non -critical system, like the oven of a cabin, not working, The DDG explains how to operate without that team while the repair is organized.
3. MEL (Minimum Equipment List)
DDG -related, he MEL It is a detailed list of systems and equipment that must be operational for a plane to fly. Everything that is not included in the MEL can be deferred under the rules of the DDG.
Importance:
A technician who dominates the MEL can make quick and successful decisions about the aptitude of a plane to operate.
4. CPCP (Corrosion Prevention and Control Program)
This program is vital to prevent corrosion in airplanes, A silent but dangerous enemy for the structure and systems of the aircraft.
Practical example:
Regular inspections of critical areas, Like wings or fuselage, They are part of the CPCP to avoid major structural problems.
5. SB (Service Bulletin)
Los Service Bulletins They are recommendations issued by manufacturers to make modifications, inspections or repairs on aircraft. Although they are not always mandatory, Many airlines adopt them to keep their fleets in optimal conditions.
Real context:
An SB could recommend a change in a component to improve your performance or prevent future failures.
6. AD (Airworthiness Directive)
Unlike SB, los AD They are mandatory and issued by the aeronautical authorities when problems are detected that affect the aircraft of an aircraft.
Example:
An AD may require an immediate inspection of a critical component after failure reports in other aircraft of the same model.
7. ETOPS (Extended Twin Operations)
This term refers to the capacity of a bimotor plane to fly away from an alternative airport.
Relevance for technicians:
Technicians working in ETOPS aircraft must ensure that systems and engines meet stricter standards.
8. Hard Time & On Condition
They are preventive maintenance strategies.
- Hard Time: The components are replaced or reviewed at fixed intervals, regardless of your status.
- On Condition: The component remains in service while complying with certain criteria.
Example:
An engine can have maintenance “On Condition” as long as anomalies in their performance are not detected.
Conclusion
The language of aeronautical maintenance can be technical and complex, But dominate terms like ADD, DDG o MEL It is essential to play an effective role in this sector. This glossary is just the beginning; The more you familiar with these concepts, Better prepared you will be to face the daily challenges in the hangar or on the track.
