History of Flight

On December 23, 1997 at 2300 central standard time (cst), a Piper PA-30/A, N9WG, sustained substantial damage when it impacted the terrain about 1/2 mile from the Hastings Airport, Hastings, Nebraska. The private pilot with an instrument rating had executed a missed approach and was making a second approach when it impacted the terrain. The pilot received fatal injuries. One passenger received minor injuries and one passenger received no injuries. The 14 CFR Part 91 flight had departed the Cheyenne Airport, Cheyenne, Wyoming, en route to Hastings, Nebraska. Instrument meteorological conditions prevailed and an instrument flight plan had been filed.

The right seat passenger reported the pilot had departed Nampa, Idaho, at about 0830 mountain standard time (mst) on December 23, 1998, with Mountain Home, Idaho, as a stopover airport, and Hastings, Nebraska, as the intended final destination airport. The direct distance between Nampa, Idaho, and Hastings, Nebraska was about 584 nautical miles.

The pilot departed Nampa, Idaho, at about 0830 mst and flew approximately 35 nautical miles to Mountain Home, Idaho, where the airplane received maintenance to the aircraft's cabin heater system. Due to maintenance complications, the flight did not depart Mountain Home until about 1500 mst.

The right seat passenger reported that as the airplane neared Cheyenne, Wyoming, the pilot became concerned about weather conditions at Hastings, Nebraska. As a precaution, the pilot landed at Cheyenne, Wyoming, at about 1830 mst to fuel the airplane and check weather.

The pilot called the Federal Aviation Administration's (FAA) Denver Automated Flight Service Station (AFSS). He received a weather brief and filed an IFR flight plan to Hastings, Nebraska.

At 1905 mst, the pilot was briefed that the current automated weather at Hastings indicated winds at 120 degrees at 4 knots, one quarter mile visibility, freezing fog, 200 foot ceiling, 3,600 foot overcast, and temperature at minus 2 degrees Celsius (C), and the dew point at minus 2 degrees C.

At 1907 mst, 1907 mst, the pilot was briefed that the current forecast up until the 2200 cst forecast called for winds at 150 degrees, 400 foot overcast, visibility occasionally 2 miles. The 2200 cst forecast weather at Hastings called for winds at 120 degrees at 6 knots, ceiling one thousand overcast, occasional visibility four miles in mist with 500 foot overcast.

At 1908 mst, the pilot was briefed that the current weather at North Platte, Nebraska, indicated calm winds, visibility 10 miles, 7,500 foot broken ceiling, 9,000 overcast, temperature minus one degree C, and dewpoint minus 7 degrees C. The briefer reported the forecast weather was basically the same as the current weather.

At 1909 mst, the pilot filed a IFR flight plan to Hastings, Nebraska. He indicated that North Platte, Nebraska, would be used as an alternate airport. The pilot reported that he had 4. 75 hours of fuel on board, with an en route time of two hours and an airspeed of 170 knots.

The pilot departed Cheyenne, Wyoming, about 1940 mst.

At 2224 cst, the pilot contacted Minneapolis Center and requested the weather at Grand Island, Nebraska, which was 20 miles north of Hastings, Nebraska. The controller reported the surface observation taken at 2156 cst indicated winds at 130 at 5 knots, visibility less that one quarter mile, freezing fog, 100 foot indefinite ceiling, temperature minus 2 degrees C, dew point minus 2 degrees C, and altimeter 29.88.

The controller briefed the pilot that the 2201 special surface observation at Hastings indicated winds at 080 degrees at 4 knots, one quarter mile visibility, freezing fog, a few clouds at 100 feet, 4,200 foot overcast, temperature minus 2 degrees C, dew point minus 2 degrees C, and altimeter 29.87.

At 2227, the pilot reported to Minneapolis Center, "Whiskey golf, we're gonna shoot an approach into Hastings, ah, if it's no good we'll, ah, do a missed and go somewhere else."

At 2227, the pilot requested and received clearance to fly the Hastings VOR 14 approach.

At 2237, the pilot reported to Minneapolis Center, "Currently four miles out, ah....(I'll) fly over the VOR and then do the published approach."

At 2244, the pilot requested a current altimeter setting for Hastings. Minneapolis Center reported the altimeter was 29.87.

At 2250, the pilot reported to Minneapolis Center, "ah, Missed approach. I (wanna) try it again."

At 2250, Minneapolis Center cleared N9WG for the VOR 14 approach.

At 2250, the pilot acknowledged that he was cleared for the approach.

There were no further radio transmissions from N9WG.

At about 2300 cst, the aircraft impacted an irrigation tower and wheel assembly that was located about 1/2 mile west of the airport. The airplane went under the irrigation pipe on top of the tower and impacted the ground. The airplane came to rest inverted about 493 feet south of the irrigation tower.

The right seat passenger was able to get out of the airplane and obtain assistance.

Hastings Fire Department personnel reported that heavy ground fog existed during their search effort.

The pilot received serious injuries and was transported to a hospital where he was later pronounced dead at 0527 cst on December 24, 1997.
