CAMERON PARISH, LA (KPLC) - The National Transportation Safety Board has cleared the crash site from Friday's downed Era helicopter in Grand Lake.
Law enforcement who were securing the premises have left the remote area in northern Cameron Parish.
Killed in the crash were William R. Croucher, 69, of California, the pilot of the aircraft; as well as mechanics, 55-year-old Michael Lee Tyree of Iowa, La., and 41-year-old Timothy Lloyd Goehring, of Sulphur.
Keith Holloway, with the NTSB Public Affairs Office, told KPLC that the investigation into the crash continues.
"The NTSB is continuing to collect information regarding this accident. So far, investigators have documented the scene and examined the aircraft. There are no new details regarding the investigation at this time," Holloway said. "As you may know, the NTSB does not determine cause at this early stage in an investigation. The information that is gathered will be analyzed and help to determine cause at some point. Many of the NTSB's investigations can take about 12 -18 months to complete. I do suspect that there will be a preliminary report available on our website in about 10 days. This report will be factual in nature only."
