Mike found Brad Guyton, president of BAG Aviation, who is an FAA A&P, with inspection authorization and an air safety and airworthiness representative. Brad worked as a director of maintenance at Hawker Beechcraft and Raytheon, and now has his own pre-buy consulting business. I have concluded I will never buy anything again, not even a toothbrush, without getting Brad to sign off on the purchase. Brad knows which service bulletins matter. He’s intimately familiar with the type of airplane sitting out there in the sun, and he’s also very closely aware of this particular airplane. He has spent days here in Wichita, examining every maintenance-log entry for this airplane. He knows why the leading edge was replaced on the left wing and what caused the fuel leak.
