An Airline Ratings study points out these planes as the least safe commercial jets to fly: LET 410, Ilyushin 72, Antonov AN-12, Twin Otter, CASA. This might be one of those cases where certain facts can’t be separated. How can statistics separate the effect of the planes being flown in third world countries with the least safe airports? How can one separate the fact of the Twin Otter’s heavy usage in Nepal, home of some of the worlds most dangerous airports?
The same study indicates Boeing’s 777, 717, 787 and 767/757, the Airbus A380 and A340, the Embraer 135/145, and CRJ 700/1000 as the safest planes.
While 137 airlines were deemed safest, only these carriers score top marks for both safety and service: Air New Zealand, Asiana Airlines, Cathay Pacific, Emirates, Etihad, EVA Air, Korean Air, Qantas, Royal Jordanian, Singapore Airlines and Virgin Atlantic.
British Airways, Flybe, Virgin Atlantic, Lufthansa and Aer Lingus were considered safe but had lesser marks for service. The full spectrum of the rated airlines is located here: http://www.airlineratings.com/ratings.php
