The NTSB concluded their investigation into the July 2002 CFIT approach accident involving a FedEx Boeing 727 at Tallahasse. The captain and first officer failed to establish and maintain a proper glidepath during the night visual approach to landing. One of the contributing factors was the first officer’s color vision deficiency, which made it difficult for him to correctly identify the color of the PAPI signal. Two safety recommendations were made to the FAA regarding color vision test protocols. (NTSB)
