Circumstances:
The twin-engine airplane collided with a residential structure and terrain following a loss of control after the pilot experienced difficulties maintaining course during an Instrument Landing System (ILS) approach while on instrument meteorological conditions. The impact occurred approximately 3.7 miles short of the approach end of the runway. Radar data depicted that after the 8,700-hour commercial pilot was vectored to the ILS Runway 3 approach, the airplane remained left throughout the approach before turning right of the localizer approximately 2 miles before the final approach fix (FAF). Radar then showed the aircraft turn to the left of course line. When the aircraft was abeam the FAF, it was approximately 1 mile left of the course line. As the aircraft closed to approximately 1.5 miles from the runway threshold, the aircraft had veered about 1.3 miles left of the course line (at which time air traffic control instructed the pilot to turn left to a heading of 270 degrees). The aircraft continued to turn left through the assigned heading and appeared to be heading back to the ILS course line. According to the radar, another aircraft was inbound on the ILS course line and Air Traffic Control Tower (ATCT) instructed the pilot to turn left immediately. Thereafter, the aircraft went below radar coverage. A witness, located approximately 1.25 miles northwest of the accident site, reported that he heard a very loud noise, and then observed an airplane flying toward a building, approximately 60 feet in height. The airplane was observed to have pitched-up approximately 45 - 90 degrees just before the building and disappeared into the clouds. A second witness located approximately 1 mile northwest of the accident site reported that he heard a low flying aircraft, and then observed a white twin engine airplane banking left out of the clouds. The airplane leveled out, and flew into the clouds again a few seconds later. The witness stated that the airplane was at an altitude of 100- 200 feet above the ground. A third witness located adjacent to the accident site reported that they heard the sound of a low flying airplane in the distance. As the sound became louder and louder, they looked up and observed the airplane in a near vertical attitude as it impacted trees and the side of an apartment complex. Examination of the airplane did not reveal any preimpact mechanical anomalies. A weather observation taken approximately 15 minutes after the accident included a visibility 4 status miles, light drizzle and mist, and an overcast ceiling at 400 feet.
Probable cause:
The pilot's failure to maintain control during an ILS approach. Contributing factors were the prevailing instrument meteorological conditions( clouds, low ceiling and drizzle/mist), and the pilot's spatial disorientation.

Circumstances:
The emergency medical services (EMS) airplane was destroyed by terrain impact and post impact fire about 7 nautical miles (nm) west of its destination airport, Dodge City Regional Airport (DDC), Dodge City, Kansas. The 14 Code of Federal Regulations Part 91 positioning flight departed the Wichita Mid-Continental Airport (ICT), Wichita, Kansas, about 0215 central standard time and was en route to DDC. Night visual meteorological conditions prevailed when the accident occurred about 0257 central standard time. The flight had been on an instrument flight rules (IFR) flight plan, but the pilot cancelled the IFR flight plan about 34 nm east of DDC and initiated a descent under visual flight rules. Radar track data indicated that the airplane maintained a magnetic course of about 265 degrees during the flight from ICT to DDC. The rate of descent was about 850 to 950 feet per minute. During the descent, the airplane flew past the airport on a 270 degree course. Witnesses in the area reported hearing the engine noise of a low-flying airplane followed by the sound of impact. One of the witnesses described the engine noise as sounding like the engines were at "full throttle." The on-site inspection revealed that the airplane impacted the terrain in a gear-up, wings-level attitude. The inspection of the airplane revealed no anomalies to the airframe or engines. A review of the pilot's 72-hour history before the accident revealed that it had been 14 hours and 32 minutes from the time the pilot reported for duty about 1225 central standard time until the time of the accident. It had been 20 hours 57 minutes from the time the pilot awoke (0600) on the morning before the accident until the time of the accident. No evidence of pilot impairment due to carbon monoxide, drugs, or medical incapacitation was found. The accident occurred during a time of day that was well past the pilot's normal bedtime and also at a time of day when the physiological need to sleep is especially strong. The findings from a Safety Board's human performance analysis indicates that the pilot was likely fatigued. A review of 14 CFR 135.267 indicated that the pilot had adhered to the flight time limitations and rest requirements specified in the regulation.
Probable cause:
The pilot failed to maintain clearance with terrain due to pilot fatigue (lack of sleep).

Captain / Total hours on type:
310.00
Circumstances:
En route from Tucson to Dodge City in good weather conditions, the right engine caught fire. The pilot shut down the engine and as he was unable to maintain a safe altitude, he attempted an emergency landing. The airplane belly landed in a field near Cliff and came to rest in flames. The pilot, sole on board, escaped uninjured while the aircraft was destroyed by a post crash fire.
Probable cause:
Powerplant fire and explosion in flight due to a cylinder assembly failure. The following contributing factors were reported:
- Powerplant detonation,
- Fire in engine,
- Intentional wheels-up landing off airport on land,
- Exhaust system: external supercharger,
- Foreign object damage, warped,
- Rough/uneven terrain,
- Hole burnt near n°2 exhaust valve seat,
- Density altitude 7,900 feet.
