Key Takeaways:
OEM service documents (e.g., Service Bulletins), while often not mandatory, are crucial for identifying and mitigating risks like corrosion, often preventing issues from escalating to mandatory Airworthiness Directives (ADs).
Aircraft corrosion is a severe threat to structural integrity, capable of causing safety hazards and increased maintenance, as demonstrated by the Learjet 45 wing spar issues that transitioned from recommended inspections to an FAA AD.
Corrosion is primarily caused by environmental factors (e.g., humidity, deicing fluids, poor maintenance) and industrial pollutants, emphasizing the necessity of preventative measures and timely adherence to service recommendations for safety and cost efficiency.
