STRONG CONSENSUS REACHED AT ICAO SAFETY CONFERENCE ON WAYS TO REDUCE ACCIDENTS
MONTREAL, 1 April 2010 – A High-Level Safety Conference which concluded today established a strong mandate for the International Civil Aviation Organization (ICAO) to create a strategy to further reduce the global accident rate, through the sharing of safety-related information among Member States and the air transport industry.

More than 600 participants at the four-day event, attended by Ministers and Directors General of Civil Aviation from 150 Member countries as well as industry representatives, recommended that ICAO create a global safety information exchange to enable analysis of key safety indicators. This will guide future strategic decisions related to the evolution of today’s air transportation system. The Conference called upon ICAO to facilitate the collection, analysis and dissemination of safety information provided by States and industry partners, throughout the international aviation community.

The Conference further recommended that ICAO develop processes to give the general public access to relevant safety information, thereby allowing them to make an informed decision about the safety of air transportation and to further ensure that such information is used solely to improve aviation safety and not for retribution or the purpose of gaining economic advantage.

“We have traditionally focused our efforts on accident reports as a means to improve safety. This new approach will help us to better identify and deal with safety threats before they result in accidents”, said Roberto Kobeh González, President of the Council of ICAO.

“Regulators and industry must come to manage safety-critical information in the same way that they view accidents. Both must become triggers for action in preventing accidents,” he added.

On Tuesday, ICAO, the Federal Aviation Administration of the United States (FAA), the Commission of the European Union (EC) and the International Air Transport Association (IATA) signed a Declaration of Intent on the development of a global safety information exchange agreement.

In the months to come, the parties will establish an operational framework for the information exchange. It will address technical, confidentiality, legal and policy implications, as well as the relevance and timing of information collected.

“ICAO has long promoted the concept of information sharing on a global scale so as to connect the various databases of regulators and industry. The recommendation from the Conference and the Declaration of Intent represent a breakthrough in achieving our objective of better utilizing data to reduce the accident rate globally and in specific regions and States around the world,” Mr. Kobeh emphasized.

On the question of black boxes, the Conference recommended that ICAO look into technical enhancements that would improve the ability to locate and recover the units, such as longer time periods for signals, better resistance to crashes and floatability.

“While the electronic transmission of information during flights is progressively improving, black boxes will remain absolutely indispensable for years to come as the primary source of technical data in cases of accidents or incidents,” Mr. Kobeh said.

The Conference also called on States and industry to ensure improved communication and surveillance of flights over oceanic and remote areas through the use of all available technologies.

Reaffirming the fundamental mission of ICAO to ensure the safety of international civil aviation, the Conference endorsed the creation of a new Annex to the Convention on International Civil Aviation, one dedicated exclusively to safety management principles.

Recommendations from the Conference will be submitted to the Council of ICAO for consideration in the coming weeks.

Sharing of Information highlight of second day of Safety Conference
March 30, 2010 — oacicomm
On the second day of the High-level safety Conference, the more than 600 participants from some 150 ICAO Member States and industry unequivocally endorsed the twin concepts of transparency and sharing of safety-related information among States and with major stakeholders within the global aviation community, as well as with the general public.

There was agreement that ICAO should be the body charged with coordinating the integration of the safety information provided by the international community as well as for the dissemination of safety intelligence. To that end, ICAO would convene a group of experts to define and harmonize safety metrics, associated data requirements and analysis processes.

ICAO would also develop a code of conduct on the sharing of safety information, so as to ensure that such information is used solely to improve aviation safety and not for retribution or the purpose of gaining economic advantage.

Processes would be developed to provide the general public with access to relevant safety information which would allow them to make an informed decision about the safety of air transportation.

Recommendations on these and other items will be reviewed and approved on the final day of the Conference, Thursday, 1 April. Recommendations will subsequently be submitted to the ICAO Council for consideration in the coming weeks.

Earlier in the Conference, in line with the discussions on the sharing of information as a means to improve aviation safety levels around the world, ICAO and three other State and industry parties signed a Declaration of Intent on the Development of a Global Safety Information Exchange Agreement: the Federal Aviation Administration of the United States (FAA); the Commission of the European Union (EC); and the International Air Transport Association (IATA).

In the weeks to come, representatives of the signatories will produce a work plan incorporating the following activities and concepts: identification of the safety information gathered by the Participants that would be most relevant to the enhancement of risk reduction activities; identification of the legal or policy constraints, if any, on the ability of Participants to share this information among the parties and development of mechanisms to overcome these constraints; identification of the appropriate timing of that information sharing; development of an efficient mechanism to ensure that this information is used to generate safety intelligence and identify critical safety trends in a timely fashion; development of policies and procedures to safeguard proprietary, confidentially submitted, and/or personal information in line with relevant applicable privacy laws, data sharing policies and regulations standardization of aspects of the audit metrics, data taxonomies etc, to maximize effective utilization of the safety information gathered in this process; and determination of how to disseminate this information globally as appropriate.

Tomorrow the conference will discuss the creation of a new Annex to the Convention on International Civil Aviation, one dedicated to safety processes.

NTSB ISSUES URGENT SAFETY RECOMMENDATION TO ADDRESS ENGINE THRUST ROLLBACK EVENTS ON B-777 AIRCRAFT

Washington, DC – Following two engine thrust rollback events on Boeing 777 aircraft powered by Rolls-Royce engines, the National Transportation Safety Board issued an urgent safety recommendation today calling for the redesign of a Rolls- Royce engine component. The Safety Board also recommended that, after the redesign is completed, the new system be installed on all affected B-777 airplanes at the next maintenance check or within six months.

These recommendations are being issued in response to the findings in two investigations – an accident and an incident – involving engine thrust rollbacks on Boeing 777-200ER airplanes powered by Rolls-Royce RB211 Trent 800 Series engines. In both cases a build-up of ice (from water normally present in all jet fuel) on the fuel/oil heat exchanger (FOHE) restricted the flow of fuel to the engine, resulting in an uncommanded engine rollback.

The first event, which is still being investigated by the UK’s Air Accidents Investigation Branch (AAIB), occurred on January 17, 2008, when a Boeing 777 experienced a dual engine rollback on final approach and crashed short of the runway at London’s Heathrow International Airport. One passenger was seriously injured, eight passengers and four of the flight crew sustained minor injuries; the airplane was substantially damaged.

The second event occurred on November 26, 2008, when a Delta Air Lines Boeing 777 experienced a single engine rollback during cruise flight over Montana while en route from Shanghai to Atlanta. Normal operations resumed after the flight crew followed Boeing’s published procedure to recover engine performance; the airplane landed safely in Atlanta.

Testing in support of the UK accident investigation led Boeing to develop procedures to help prevent ice accumulation, and to recover thrust in cases of ice blockage. As more information from the Delta rollback event was developed, Boeing modified the procedures, which became the basis of an airworthiness directive issued by the Federal Aviation Administration.

While the procedures may reduce the risk of a rollback in one or both engines due to FOHE ice blockage, they add complexity to flight crew operations, and the level of risk reduction is not well established. And because the recovery procedure requires a descent, the aircraft may be exposed to other risks such as rising terrain or hazardous weather, or the inability to achieve maximum thrust during a critical phase of flight, such as during a missed approach.

Because of these hazards, the Safety Board has determined that the only acceptable solution to this safety vulnerability is a redesigned FOHE that would eliminate the potential of ice build-up. On February 23, 2009, Rolls-Royce indicated that a redesign of the FOHE was underway, and that they anticipated the redesign to be tested, certified and ready for installation within 12 months.

“With two of these rollback events occurring within a year, we believe that there is a high probability of something similar happening again,” said NTSB Acting Chairman Mark V. Rosenker. “We are encouraged to see that Rolls-Royce is already working on a redesign, and we are confident that with the FAA and EASA (European Aviation Safety Agency) overseeing the process, this flight safety issue – even one as complex as this – will be successfully and expeditiously resolved.”

The NTSB has made the following two recommendations to both the Federal Aviation Administration and the European Aviation Safety Agency:

Require that Rolls-Royce redesign the RB211 Trent 800 series engine fuel/oil heat exchanger (FOHE) such that ice accumulation on the face of the FOHE will not restrict fuel flow to the extent that the ability to achieve commanded thrust is reduced.
Once the fuel/oil heat exchanger (FOHE) is redesigned and approved by certification authorities, require that operators of Boeing 777-200 airplanes powered by Rolls Royce RB211 Trent 800 series engines install the redesigned FOHE at the next scheduled maintenance opportunity or within 6 months after the revised FOHE design has been certificated, whichever comes first.

The NTSB and AAIB will continue to work together closely on both of the rollback events as each of the investigations move forward.
