The NTSB's narrative for the Bell 206B final · quoted from the NTSB record

N115AL, a Bell 206B helicopter, and N2773A, a Bell 206L-1 helicopter, collided in midair approximately 3 nm west of Intracoastal City, Louisiana. N2773A was in cruise flight, transiting through the Intracoastal City traffic advisory area from northeast to southwest. N115AL departed Intracoastal City westbound. Radar data indicated that the angle between the flight paths was about 60 degrees. The pilot of N115AL reported that he had just leveled out at 700 feet agl when he saw N2773A to his right at a 'slightly' lower altitude and banked hard left. A witness and physical evidence indicated that the main rotor blades of N115AL struck the tail rotor of N2773A. N2773A was not observed to take evasive action. Subsequently, N2773A impacted the ground in an uncontrolled descent, and N115AL made a forced landing in a slough and sank. Prior to departure, the pilot of N115AL communicated his intentions on the local traffic advisory frequency. There were no radio communications from N2773A on the advisory frequency, and the operator of N2773A did not include the use of traffic advisory services as a company standard operating procedure in its operations manual.

The complete narrative as the NTSB published it. The NTSB's docket holds the report as a PDF and any photographs, statements and other documents from the investigation.

Documents from the investigation the NTSB's docket: the evidence folder behind the report

The docket, the folder of records gathered during an investigation (maintenance records, photographs, witness statements, examinations), has not been read from the NTSB for this case yet; the list appears here once it has. Open the docket at the NTSB.

Everything on this page comes from the NTSB's public records. The narrative, probable cause and findings are the NTSB's own words; the coded tables behind the report are written out in plain English, with pilots' ages, home towns and medical details left out. The documents and photographs are the NTSB's docket, shown as the NTSB released them. This site's own text never names anyone involved. A preliminary report can change; the final report usually follows one to two years later, and the page is refreshed when it does.
