NTSB Factual Report

HISTORY OF FLIGHT

On January 18, 2005, approximately 1128 central standard time, a Cessna T-37B, a twin-turbojet military trainer, tail number 66-8003, operating under the call sign Cider 21, and an Air Tractor AT-502B single-engine agricultural airplane, N8526M, were destroyed following a midair collision during cruise flight near Hollister, Oklahoma. The T-37B was registered to and operated by the United States Air Force (USAF). The AT-502B was registered to a private individual and operated by a commercial pilot. The USAF flight instructor pilot was not injured and the USAF student pilot sustained minor injuries. The commercial pilot in the AT-502B was fatally injured. Visual meteorological conditions prevailed and the airplanes were operating in Class E airspace. The T-37B was in radar contact with approach control and was operating under Air Force Instructions (AFI) 11-202, Volume III. The AT-502B was operating under 14 Code of Federal Regulations Part 91 for the delivery flight, and a flight plan was not filed. The local flight for the T-37B originated from the Sheppard Air Force Base (SPS), near Wichita Falls, Texas, approximately 1022. The cross-country flight for the AT-502B originated from the Olney Municipal Airport, near Olney, Texas, approximately 1100, and was destined for Huron, South Dakota, with an intermediate fuel stop in Hutchinson, Kansas.

According to company personnel from an Air Tractor dealership in Arkansas, the pilot was hired to deliver the recently purchased AT-502B to the new owner in Huron, South Dakota. Company personnel at the Air Tractor factory located in Olney, Texas, reported that the AT-502B was equipped with basic visual flight rules (VFR) instruments and was not equipped with any radios or a transponder.

During an interview with the NTSB investigator-in-charge (IIC), the USAF flight instructor and student pilot reported that they were on a routine mission training flight (C2803). After a non-eventful departure from SPS, they performed two normal overhead approaches to SPS before being cleared into the Military Operations Area (MOA). After completing the series of high altitude maneuvers, the training flight received radar vectors to the RANCH intersection and then to the Frederick Municipal Airport (FDR), near Frederick, Oklahoma, which is commonly referred to by the USAF as "Hacker." As the flight descended to an altitude of 6,000 feet, the instructor noted the bottom of the overcast cloud ceiling to be between 6,000 and 6,500 feet mean sea level (msl).

After arriving at Hacker, the training flight performed a straight in no flap landing, and requested left closed traffic for practice landings. After completing a normal overhead approach and a single-engine landing, the flight proceeded to depart Hacker's airspace to the east and climbed to 5,500 feet msl.

The student pilot reported that he performed the en route portion of his checklist and contacted USAF Radar Approach Control (RAPCON) to notify them they were en route back to Sheppard Air Force Base and requested the "home plate" arrival. RAPCON advised the flight that they had radar contact, and to descend to 5,000 feet msl on a heading of 100 degrees.

The student pilot reported that after he leveled off at 5,000 feet msl at an indicated airspeed of 200 knots, the flight instructor took control of the T-37B. The student pilot stated that as the flight instructor took control of the aircraft, he scanned outside the airplane to the left, and started to look back to the right when he saw the yellow Air Tractor heading toward the right side of the T-37B. He reported, "… I saw the crop duster and it was just an immediate … it wasn't like I saw him moving, it's just like it grew and my jaw just dropped and I didn't say anything. I was just … I just said, "Sir," because I was just shocked and as soon as I said that, we just impacted and went out of control."

The instructor pilot stated that he took control of the airplane while still in the descent and he leveled the airplane at 5,000 feet msl. He reported that he briefly scanned at the student pilot's altimeter on the left side of the instrument panel (a standard practice for T-37 flight instructors). As he was turning his head back to the right, he noticed a "high visibility yellow airplane" out of the right corner of his eye, but did not have time to take evasive action.

Both pilots reported that the T-37B was level at 5,000 feet msl for about one minute or less before impact with the AT-502B. The instructor and student pilot recalled feeling a spinning sensation and rolling inverted. Both the instructor and student pilot initiated emergency egress procedures and ejected from the aircraft.

The T-37B and AT-502B impacted farm fields about 3.5 nautical miles (nm) east of Hollister, Oklahoma. Both aircraft were partially consumed by post impact fires.

A witness located north of the accident site reported in a written statement that he observed an aircraft descending rapidly in a nose down attitude and on fire prior to losing sight of it behind a tree line. Subsequently, the witness observed a second aircraft spinning in a nose down attitude, and it was missing a wing. The witness added that a plume of smoke was originating from the airplane but he didn't see any flames. As the airplane continued to descend, he noticed two parachutes on each side of the airplane, and he decided to proceed to the area to see if he could assist the pilots.

AIRPORT INFORMATION

SPS is operated under class D airspace and is attended continuously. All radio and telephone voice traffic to SPS Tower and RAPCON are recorded through the Digital Voice Recording System (DVRS). The type of radar utilized at SPS is a GPN-20 radar system, but it has no recording capability.

FDR, located 33nm northwest of SPS, is operated under Class G airspace. FDR is used by Sheppard Air Force Base T-37 jet trainers for high density student pilot training. This training is conducted on weekdays during daylight hours. T-37 aircraft are controlled by the red and white runway supervisory units (Call sign: "Hacker") at the end of runways 17R and 35L. Normal T-37 pattern altitude is 2,200 feet msl. Straight-ins are flown at 1,700 feet msl. All civilian traffic is recommended to contact Hacker on 122.80 megahertz or UHF 285.7 when approximately 10 miles from the field. Hacker controls T-37 aircraft, but is an advisory-only service to civilian aircraft.

The alert area surrounding FDR is depicted as the A-561 High Density Student Training area on the Dallas-Fort Worth Sectional Aeronautical Chart. The vertical boundary is from the surface to 4,000 feet msl, an

NTSB Probable Cause

The pilots of the T-37B and AT-502B the failed to maintain adequate visual lookout and did not maintain clearance from the other aircraft. Contributing factors included the lack of a transponder and radios on the AT-502B and the reduced visibility due to haze.
