A Pima County Arizona Sheriff's Department helicopter with four souls on board crashed Monday morning around 1130 am while scouting an area for new communication towers. The pilot, Loren Leonberger 60, was fatally injured in the crash. Of the three other occupants on board the helicopter two were reported to be in serious condition and on was reported to be in critical condition.
The civilian pilot, Leonberger, first flew helicopters with the U.S. Army in Vietnam in 1970. Prior to coming to work for the Pima County Sheriff's Department he worked as a helicopter pilot for the Maricopa County Sheriff's Department. The crash occurred approximately 40 miles northwest of Tucson International airport in a rugged area of Waterman Mountain, in the Ironwood Forest National Monument area. The exact circumstances of the crash are uncertain at this time according to the FAA.
After the crash one passenger identified as Edwin Nettleton (58), a radio engineer, called 911 to report the crash and advise that he was afraid the helicopter wreckage would fall over a cliff if he attempted to climb out. He also expressed his concern about fire. Nettleton told dispatchers that he suffered a broken wrist in the crash.
According the rescuers on scene the helicopter did apparently tumble 100 to 150 yards down the side of the mountain before it came to rest against a tree.
While the helicopter crash investigation is in the very early stages and it is unknown if weather played a factor, there were some reports of a hail storm approximately 3 miles from the crash site, around the time of the crash. However, records at the Marana airport, closest to the crash site showed that winds there were calm.
In the past the Pima County Sheriff's Department operated one MD 530F helicopter, which the same make and model helicopter reported to be involved in the crash.
The MD 500 series helicopter is a reliable, and rugged 4 passenger helicopter well suited for off field and rescue work in- rugged terrain. The MD 530F is the preferred patrol helicopter for many agencies including the San Diego Sheriff's Department. One of the things that makes the MD530F popular among pilots is it's reputation for survivability in crashes.
