Dette høres nesten tåpelig ut gitt EASAs reaksjon på to identiske helikopterhavarier. Selv noe så opp i dagen like ulykker velger EASA allikevel å forholde seg mer til helikopterprodusenten enn til vår egen SHT. (Red,)
EASA aims to fine-tune safety-risk analysis
Forty years
after the worst accident in civil aviation history, European authorities are
transitioning to a new method of assessing safety risk.
Safety
performance has typically been monitored through the blunt tool of counting
accidents and serious incidents.
But the European Aviation Safety Agency
states that this method is "not a good risk measure".
In a preliminary
safety review covering 2016 the authority says the accident rate of
European-operated commercial air transport has been broadly downwards since
2012, to around three per million flights.
The overall number of
accidents last year, 18, was the lowest figure for a decade but, in contrast,
the number of serious incidents, more than 100, was the highest in the same
period.
"This increase was mainly attributable to occurrences relating to
technical failures of aircraft systems, medical, runway excursion and loss of
separation," says EASA.
EASA says a new common risk-classification scheme
due for implementation this year will "provide a better picture" of safety
risks.
The scheme emerged from a European Union directive requiring
development, by May 2017, of a mechanism by which necessary rapid action could
be identified through analysis of individual safety occurrences.
"Such a
scheme should help the relevant entities in their assessment of occurrences and
in determining where best to focus their efforts," the directive
states.
IATA states that the commercial airline industry's accident rate
declined to 1.61 per million flights last year, from the previous level of
1.79.
It released its accident statistics days before the 40th
anniversary of the Boeing 747 runway collision in Tenerife in March 1977, which
resulted in over 580 fatalities and remains the highest-casualty accident in
civil aviation history.
The major jet accident rate increased slightly to
0.39, one of the parameters in which the association acknowledges the industry
took a "step back".
But the relative rarity of accidents means that the
statistics are easily skewed by individual occurrences, highlighting the need
for a more finely-tuned method of analysis.
The European scheme is
intended to collate occurrence reports in a format which will facilitate
information exchange.
EASA says: "The scheme will help to shift the focus
to the probable potential harm of identified hazards to the European aviation
system instead of directly measuring the severity of a realised outcome."
