The International Air Transport Association (IATA) last week announced that the 2012 global accident rate for Western-built jets was the lowest in aviation history.
“The industry’s 2012 record safety performance was the best in history. Each day approximately 100,000 flights arrive safely at their destination. Airlines, airports, air navigation service providers, manufacturers and safety regulators work together to ensure every flight is as safe as possible. Their dedication and cooperation has made air travel remarkably safe. Nevertheless, there is still work to do. Every accident is one too many and each fatality is a human tragedy. The first commercial airline flight took place on 1 January 1914. Since then the very first flight the airline industry has made continuous improvement in safety its top priority,” said Tony Tyler, IATA’s Director General and CEO.
Safety by the numbers:
IOSA
Airlines on the IATA Operational Safety Audit Registry (IOSA) experienced no Western-built jet hull loss accidents. The total accident rate (all aircraft types) for IOSA registered carriers was 4.3 times better than the rate for non-IOSA carriers (0.96 vs. 4.11). Today 381 airlines are on the IOSA registry (www.iata.org/registry).
For IATA’s 240+ airlines IOSA is a requirement for membership in the association. That some 140 non-member airlines are on the registry is a clear indication that IOSA has become the global benchmark for airline operational safety management.
“IOSA once again demonstrated its positive impact on aviation safety. Carriers on the IOSA registry recorded an accident rate that was more than four times better than their non-registered counterparts. Not only did IOSA registered carriers have a lower accident rate but the accidents were less severe in terms of fatalities and damage to aircraft,” said Tyler.
During 2012, IATA continued its work with airline members to develop the Enhanced IOSA. Enhanced IOSA adds a further dimension with a focus on airlines’ internal quality assurance program to implement self-auditing methodology based on IOSA principles.
Regional highlights — Western-built jet hull loss rates
Safety in Africa
Africa’s Western-built jet hull loss rate showed a higher rate versus 2011 (3.71 vs. 3.27). The region’s accident rate for all aircraft types more than doubled (12.44 accidents per million flights from 6.17 in 2011), with 13 accidents in 2012 (up from 8 accidents in 2011).
African airlines on the IOSA registry had no accidents.
“Africa is a continent divided on performance. Airlines on the IOSA registry are performing at or above industry average rates. But the continent’s overall performance is far from satisfactory. It should be as safe to travel by air in Africa as it is in any other part of the world,” said Tyler.
In May 2012, IATA, with the International Civil Aviation Organization (ICAO) and a host of other organisations, committed to an Africa Strategic Improvement Action Plan aimed at addressing safety deficiencies and strengthening regulatory oversight in the region by 2015. The Plan was endorsed as part of the ‘Abuja Declaration’ by the Ministerial meeting on Aviation Safety and Security of the African Union in July and endorsed at the Assembly of the African Union in January 2013.
“Stakeholders are united in their commitment to bring all of Africa to world class safety levels through the adoption of global standards. Passage of the Abuja Declaration is a key step along this path,” Tyler said. Critical to the success of this plan is mandatory adoption of IOSA by African states.
Accident analysis Runway excursions
Runway excursions, in which an aircraft departs a runway during a landing or takeoff, were the most common type of accident in 2012 (28% of total accidents). Most (82%) of runway excursions occur following a stable approach where the aircraft floated beyond the normal touchdown point, or braking devices did not activate in a timely manner, or because directional control was not maintained after landing.
This type of accident continues to present challenges for the industry. Despite an increase in the runway excursion accident rate in 2012, the five-year trend in actual accidents remains downward (2008:28, 2009:23, 2010:20, 2011:17, 2012:21). In 2013, IATA will continue to work with industry partners to support regional runway safety seminars and to update the IATA Runway Excursion Risk Reduction (RERR) toolkit. Furthermore, IOSA now requires that airlines make use of Flight Data Analysis (FDA) programs which can help identify precursors to runway excursions.
Loss of Control In-flight
Loss of Control In-flight (LOC-I) is not one of the most common accident categories (In 2008 there were 14 LOC-I accidents followed by: 2009:9, 2010:10, 2011:8, 2012:6). However, LOC-I accidents result in the most fatalities (43% of all fatal accidents and 60% of all fatalities from 2008-2012). IATA is working with industry partners to implement a global LOC-I prevention program that will assist operators to understand the factors involved in these events. In addition, this program will provide guidance for an enhanced pilot training and establish a process for feedback into the IATA Training and Qualification Initiative (ITQI).
Sharing information
Data sharing is crucial to identifying trends that could indicate a potential safety issue. In 2009, IATA launched the Global Safety Information Center (GSIC). This incorporates operational and safety information fed by seven different databases. These are accident data, operational safety reports, IOSA and IATA Safety Audit for Ground Operations (ISAGO) audit findings, Flight Data eXchange (FDX), an aircraft ground damage database and a new cabin safety operational report database. More than 460 different organisations around the globe are already submitting information to GSIC. Continuing with the work started with GSIC, IATA is introducing the new operational data management initiative, incorporating GSIC and expanding data management into other arenas such as operations and infrastructure.
“Data collection and analysis underpins all safety efforts. The more we understand about how accidents and incidents occur, the better equipped we are to identify the risk factors. This allows us to take mitigation steps long before risks become a safety issue that could contribute to an accident,” said Tyler.
“In a little more than one lifetime, aviation has gone from being a high risk activity to a routine part of daily life. As commercial aviation prepares to enter its second century, we must live up to the ideals of our industry’s pioneers and recommit ourselves to making aviation ever safer,” said Tyler.
