Corrosion in Aviation Maintenance
The Invisible Threat in Aviation Maintenance.
In the world of aircraft maintenance, corrosion is not just a maintenance issue it’s a matter of safety and cost.
According to FAA Advisory Circular 43-4B, corrosion in aircraft structures and engine materials demands systematic inspection, treatment, and control.
Research shows that corrosion-related fatigue or structural deterioration accounts for about 20% of all accidents attributed to corrosion in aviation.
The worldwide market for aircraft corrosion control services was estimated at US $2.81 billion in 2024, and is anticipated to steadily expand as fleets age and maintenance standards intensify.
For an Aircraft Maintenance Technician, prevention is paramount:
• Conduct thorough cleaning and inspection of critical areas (fan frames, engine casings, structural joints)
• Implement corrosion-inhibiting treatments and protective coatings
• Maintain detailed records, monitor recurring problems, and support a robust Quality Assurance program.
When we manage corrosion, it's not merely about prolonging the lifespan of components; it's about safeguarding the integrity of flight.
