NTSB To Wrap Up On-Scene Portion of Grand Canyon Investigation Today

August 17, 2001

Washington DC - National Transportation Safety Board investigators will wrap up today the on-scene portion of their investigation into the August 10, 2001 crash of a Eurocopter AS 350 B2 helicopter near the Grand Canyon. While the on-scene portion of the accident is concluding, the investigative groups will continue their work in various locations. Investigative groups formed for this investigation are as follows: Operations, Systems and Structures, Maintenance Records and Powerplants.

The Operations group has interviewed other pilots and employees of Papillion Grand Canyon Helicopters and several witnesses. Investigators are also in the process of collecting radar data for the accident aircraft from the Federal Aviation Administration and Nellis Air Force Base, Las Vegas, Nevada.

The Systems and Structures group has examined and documented the wreckage both at the accident site and at a hangar in Boulder City, Nevada. Fuel samples have been obtained from the fuel truck at the Grand Canyon West Airport and from the aircraft's pre-flight fuel sample. These samples will be sent to a laboratory for further testing.

The Powerplants group has examined and documented the engines. The engine will be sent to the Turbomeca plant in Grand Prairie, Texas. The main transmission and drive shafts have been sent to the Eurocopter facility also in Grand Prairie, Texas. Testing on these parts is scheduled to resume at the end of the month under NTSB supervision.

The Maintenance Records and Operations groups continue their routine examination of aircraft and pilot history records.

Additional factual updates will be provided as information is developed. The status of the investigation can be followed on the Board's website at www.ntsb.gov <http://www.ntsb.gov>.
