The report revealed that the pilot had failed to perform correct navigation and landing procedures on previous occasions, but no action had been taken by the airline to remove him from transporting passengers. Lutz had twice failed to upgrade his flight certifications to the more complex MD-80 due to insufficient comprehension of its computerized navigational systems. The report also documented Lutz's role in causing the total loss of a Crossair Saab 340 by retracting its landing gear while it was still on the apron, which led to Crossair relieving him of his training captain duties in 1991.
