The number of fatal accidents on world airlines rose last year but the number of people killed was the lowest since 2004, figures have shown.
There were 32 fatal crashes in 2011 - six more than in 2010 and above the average of 31 over the last decade, statistics compiled by Flight International magazine showed.
But the 2011 death figure in these accidents was 514 - well below the decade-long average of 751 and also well down on the figure of 817 in 2010.
The 2011 figures include scheduled and charter airline flights as well as freight flights and plane re-positioning flights.
The magazine said the reason the death toll was comparatively low last year was that a number of fatal accidents involved small regional aircraft.
There were nine fatal jet accidents in 2011, but two of these involved freighters and two others small regional jets.
The two worst accidents - both involving 77 deaths - involved Boeing 727s, with one crashing in the Democratic Republic of Congo in Africa and the other going down near Orumiyeh in Iran.
With more flights taking place in 2011 than the previous year, the fatal accident rate actually improved, from one fatal accident per 1.3 million flights in 2010 to one per 1.52 million flights in 2011.
