On October 31, 1999, at 1505 central standard time, a Cessna 182Q, N759NT, piloted by a private pilot, sustained substantial damage when it collided with terrain following an aborted takeoff from runway 34 (2,613 feet by 40 feet, dry/asphalt) at the Benton Airport, Benton, Kansas. The personal 14 CFR Part 91 flight was operating on an instrument flight plan. Visual meteorological conditions prevailed at the time of the accident. The pilot, who was the sole occupant, received minor injuries. The flight was originating at the time of the accident and was en route to the Indianapolis Metropolitan Airport, Indianapolis, Indiana.

The aircraft ran off of the north end of the runway, proceeded across a road and came to rest in a ditch on the north side of the road. The pilot was attempting to abort the takeoff.

According to a FAA inspector that responded to the accident scene, there were approximately 800 feet of tire marks on the runway leading to the aircraft's resting place. The throttle was found in the full forward position. No anomalies were found with respect to the aircraft or it's systems that could be associated with a preexisting condition.

The pilot appeared to be confused and disoriented and was subsequently take to a hospital in Wichita, Kansas.

The following pertinent medical information was extracted by the NTSB Medical Officer from the pilot's medical records obtained under subpoena from Wesley Medical Center:

The pilot was admitted following the accident and was noted to have "mental status changes" and to be "answering questions inappropriately at times." He underwent a CT scan and then an MRI of his head that revealed a "large, irregular ring-enhancing mass in the right parietal region measuring about 3.5 cm in diameter with a large amount of central necrosis and surrounding vasogenic edema." On the day of admission, physician notes indicate that the pilot's family "reports long history of headaches, positive HIV status, and 2 days of severe headache, slurred speech and left upper extremity weakness before accident." Notes also indicate that the pilot stated that he was "off all antiviral medications." During his hospitalization, he was noted to have "seizure activity left upper extremity" and, after consultation with his personal physician at Indiana University, was started on medication for CNS toxoplasmosis and transferred to Indiana University Medical Center for continuing treatment.

The following pertinent medical information was extracted by the NTSB Medical Officer from the pilot's medical records obtained under subpoena from Indiana University Medical Center:

Notes from his hospitalization at Indiana University Medical Center (after transfer from Wesley Medical Center following the accident) indicate that he had "likely CNS [central nervous system] toxoplasmosis." Laboratory blood testing for toxoplasma IgG during that hospitalization indicates "antibody detected." Clinic notes following that hospitalization indicate that he "has been treated for presumed toxoplasmosis and has been responding well to his medications," that his "mental status is back to normal," and later that "he improved clinically and had regression of the lesion to form a calcified stable lesion last viewed on MR in February 2000."

The pilot was diagnosed with AIDS in July 1995 following hospitalization for pneumocystis pneumonia. He was seen in outpatient clinic approximately every month through the time of the accident. Over the next several years, he was treated with multiple antiviral medications and was hospitalized at least 6 times for complications of AIDS or medications for the treatment of AIDS, including emergent surgical removal of his colon in 1997 for colitis and several admissions for transfusion due to severe anemia (twice within the three months preceding the accident). His viral load approximately 5 months prior to the accident was 750,000 and his CD4 count was 9. In June of 1998, clinic notes indicate that he was "interested in potentially a part-time job, such as flying with an airline, and had some questions, today, regarding whether the prednisone or any of the other medications he is on would sway a drug screen that would normally be given by an airline."

The following pertinent medical information was extracted by the NTSB Medical Officer from the medical records maintained on the pilot by the FAA Civil Aeromedical Institute Aeromedical Certification Division:

Electronic records of physical examinations performed on the pilot for medical certification note examinations in 1983, 1987, 1991, and 1995. None of these indicates any abnormalities. A copy of the most recent application for airman medical certificate physical examination form, dated 11/24/98, also notes no abnormalities, and the applicant specifically indicates "no" to the following questions: 17. Do you currently use any medication? 18. Have you ever had or have you now any of the following? i. Stomach, liver, or intestinal trouble u. Admission to hospital x. Other illness, disability, or surgery Under item 19, Visits to Health Professional Within Last 3 Years, the applicant notes only "influenza vaccination" on 11/24/98.

As of June 8, 2001, the pilot has failed to file a report of the accident with the NTSB.
