IATA shows airliner safety has stopped improving
By David Learmount
The global average jet hull-loss accident rate has levelled out, according to
International Air Transport Association (IATA) figures, having been improving
steadily from 1998 to 2006. Presenting figures for recent years to 1
December, the Western-built jet hull loss rate per million flights is 0.77
this year compared with 0.75 in 2007. The best-ever figure of 0.63 was in
2006.
IATA points out that the same effect is showing in the comparable accident
rate for its member carriers - now all required to have completed an IATA
operational safety audit by the end of 2008 - with 0.47 hull losses per
million flights to 1 December this year compared with 0.68 in 2007, but its
best-ever year was in 2005 at 0.43.
Preliminary IATA figures for world regions show that the poor performers
include the CIS countries, which have gone from a zero rate per million
flights in 2007 to 7.92 this year, making it the worst regional performer of
all for Western jet hull losses. Meanwhile, Latin America has worsened
year-on-year from 1.76 to 2.77, the Middle East and North Africa from 1.18 to
2.22, Europe from 0.32 to 0.45, and North America from 0.1 to 0.48. The
regional improvers are southern Africa, moving from 4.46 to 2.11, Asia
Pacific, down to 0.32 from 3.01, and north Asia (not including the CIS),
which has improved from 0.97 to a zero accident rate per million flights.
IATA's senior vice-president safety, operations and infrastructure, Günther
Matschnigg, says the association has a six-point plan for global safety
improvement based on audit and data analysis, but also increasing pressure
for infrastructure improvement. Director-general Giovanni Bisignani says
Brazil is an example of a country improving its infrastructure. Following the
fatal mid-air collision in 2006 between a Gol Boeing 737-800 and an Embraer
Legacy business jet, it is committed to bringing its military-run air traffic
management systems under civil control.
Among the accident causes, runway excursion topped the list, being
responsible for 26% of hull losses. Ground damage came next at 19%, gear-up
landings plus gear collapse events constituted 15%, and loss of control in
flight 13%. Other categories such as hard landings, undershoot, controlled
flight into terrain, in-flight damage and tailstrike were all in single
figures.
IATA points out that the full annual figures will alter according to what
happens in December.
