On July 18, 2006, at 1505 Hawaiian standard time, an amateur-built Hammack Air Command Elite gyrocopter, N6111A, collided with terrain after the pilot experienced a loss of control near Hilo Municipal Airport, Hilo, Hawaii. The pilot/owner was operating the gyrocopter under the provisions of 14 CFR Part 91. The commercial pilot, the sole occupant, was seriously injured; the gyrocopter sustained substantial damage. The personal local flight departed from Hilo about 10 minutes prior to the mishap. Visual meteorological conditions prevailed and a flight plan had not been filed.
During a telephone interview with a National Transportation Safety Board investigator, the pilot stated that he departed runway 03. He continued toward the coastline and planned to return back to the airport to perform touch-and-go practice takeoffs and landings. While making a right turn (toward the east), with the gyrocopter about 50 feet above ground level (agl), he experienced a loss of control. The aircraft collided with terrain about 15 feet from the main road Kalanianaole, located north of the airport.
The pilot further stated that he believed a pushrod had separated in the gyrocopter's controls. He added that he constructed and regularly maintains N6111A. He has amassed about 65 flight hours in the gyrocopter over the duration of 2 to 3 years.
