AIRCRAFT ACCIDENT REPORT
BEECH BONANZA, N 3794N
MASON CITY, IOWA
FEBRUARY 3, 1959
SYNOPSIS
A Beach Bonanza, N 3794N, crashed at night approximately 5 miles northwest of the Mason City Municipal Airport, Mason City, Iowa, at approximately 0100, February 3, 1959. The pilot and three passengers were killed and the aircraft was demolished.
The aircraft was observed to take off toward the south in a normal manner, turn and climb to an estimated altitude of 800 feet, and then head in a north-westerly direction. when approximately 5 miles had been traversed, the tail light at the aircraft was seen to descend gradually until it disappeared from sight. Following this, many unsuccessful attempts were made to contact the aircraft by radio. The wreckage was found in a field later that morning.
This accident, like so many before it, was caused by the pilot's decision to undertake a night in which the likelihood of encountering instrument conditions existed, in the mistaken belief that he could cope with en route instrument weather conditions, without having the necessary familiarization with the instruments in the aircraft and without being properly certificated to fly solely by instruments.
Investigation
Charles Hardin, J. P. Richardson, and Richard Valenzuela were members of a group of entertainers appearing in Clear Lake, Iowa, the night of February 2, 1959. The following night they were to appear in Moorhead, Minnesota. Because of bus trouble, which had plagued the group, these three decided to go to Moorhead ahead of the others. Accordingly, arrangements were made through Roger Peterson of the Dwyer Flying Service, Inc., located on the Mason city Airport, to charter an aircraft to fly to Fargo, North Dakota, the nearest airport to Moorhead.
At approximately 1730,[1] Pilot Peterson went to the Air Traffic communications station (ATCS), which was located in a tower on top of the Administration Building, to obtain the necessary weather information pertinent to the night. This included the current weather at Mason City, Iowa; Minneapolis, Redwood Falls, and Alexandria, Minnesota; and the terminal forecast for Fargo, North Dakota. He was advised by the communicator that all these stations were reporting ceilings of 5,000 feet or better and visibilities of 10 miles or above; also, that the Fargo terminal forecast indicated the possibility or light snow showers after 0200 and a cold frontal passage about 0400. The communicator told Peterson that a later terminal forecast would be available at 2300. At 2200 and again at 2320 Pilot Peterson called ATCS
