Okay, let’s break it down. Kevin has 23 years of experience in the aviation industry, which is a significant amount of time. He holds a degree from Embry-Riddle Aeronautical University, which is a reputable institution for aviation education. His role as Director of Maintenance at Aero Air LLC suggests he has a high level of expertise in aircraft maintenance. Considering his experience, education, and role, I would estimate his hourly rate to be around $125. This is slightly lower than the average rate for experienced aircraft maintenance professionals, but it's still a competitive rate for someone with his level of expertise and experience. Some sources suggest that aircraft maintenance professionals with 20-30 years of experience can earn upwards of $200-$300 per hour, but Kevin's role and location may affect his earning potential.
