Key Takeaways:
OEM Service Bulletins (SBs), though not mandatory, are crucial for early detection of issues like corrosion, often preventing escalation to costly and legally binding Airworthiness Directives (ADs).
Aircraft corrosion is a severe safety hazard, capable of weakening structural integrity, and is caused by environmental factors (e.g., humidity, deicing fluids) and industrial pollutants.
The Learjet 45 wing spar corrosion issues serve as a prime example, illustrating how initial SBs eventually became mandatory ADs and required expensive structural repairs, highlighting the importance of proactive maintenance for safety and cost efficiency.
