Data Analysis:
The JHSAT team has completed processing 197 accidents from the NTSB year 2000 docket dataset (~4000 files)
For each accident the JHSAT has:reconstructed the sequence of eventsidentified what went wrong and why it went wrongassigned an appropriate problem statementidentified appropriate corrective action(s)scored findings based on validity, importance, ability
and usage

Engaging with the international community
A structured approach will be used to manage the analytical and implementation work sponsored by the IHST.
Key attributes:
All recommendations will be data driven
Regional ownership - Data is owned and analyzed by those most familiar with it. Safety recommendations will be implemented by teams most familiar with local needs.
JHSAT and JHSIT lead teams will be responsible for training/coaching regional teams, measuring the results of the safety recommendations and implementation effectiveness.
20JHSAT - June 2007
Engaging with the international community
The preceding slides show the criticality of working with the international community to reduce worldwide rates is readily apparent since the US accounts for only 35 to 40% of accidents on an annual basis.
On-going efforts to identify partners from Asia, South America, Oceania, Africa, India, Middle East, etc.
EASA has established the EHSAT, fine-tuning the process
Canada, Australia and India forming JHSAT teams
Any entity that possess large helicopter accident datasets that could be processed by the JHSAT method should be considered.

Potential Barriers:
JHSAT:Variation in dataset quality, definitions, etc, around the world may make use of a standardized JHSAT approach more difficult.
Military data may not be available.
Availability of fleet hours may complicate ability to measure results.
Regional teams may be difficult to staff with sufficient level of expertise representing manufacturers, operators and regulatory interests.
JHSIT:Regional operations and regulations may make some implementation actions difficult.

Interim Recommendations
24JHSAT - June 2007
Interim recommendationsReports reviewed by the JHSAT:NASA - U.S. Civil Rotorcraft Accidents, 1963 Through 1997NASA - Analysis of US Civil Rotorcraft Accidents from 1990 to 1996 and Implications for a Safety Program NASA - ASRS Rotorcraft Incident Study - Draft Data Summary Aviation Safety Reporting SystemNASA - Helicopter Accident Analysis TeamAMPA - A Safety Review and Risk Assessment in Air Medical TransportCRS - Report for Congress - Military Aviation SafetyOGP - Safety Performance of Helicopter Operations in the Oil and Gas Industry - 2000 DataTSB Canada - Lessons Learned from TSB Investigation of Helicopter Accidents (1994 - 2003)Bell Textron - History of Helicopter SafetyOther NTSB and international reports may be considered.
The JHSAT has identified important recommendations from a series of existing helicopter safety reports. (listed on the next slide)
These recommendations were submitted to the IHST in November so that the JHSIT would have foundational intervention areas to consider.
The JHSAT plan to issue its full set of analytical results by 2Q07 which will significantly augment these foundational areas.
25JHSAT - June 2007
US JHSAT interim recommendations:
1. – Promote the adoption of Safety Management Systems in the helicopter community.
2. – More consistent and comprehensive NTSB involvement and investigation needed in helicopter accidents.
3. – Reestablish the collection of worldwide helicopter fleet hour data as previously performed by the FAA.
4. – Establish a helicopter safety website to disseminate important information
5. – Use proximity detection equipment in helicopters.
6. – Use flight recording devices and cockpit image recording systems in helicopters.
7. – Develop a strategy to improve pilot Aeronautical Decision Making.
