Airline Regulators Grapple With Engine-Shutdown Peril

Investigators Find New Icing Threat; FAA Proposes Rules

As a Qatar Airways flight dodged thunderstorms on approach to Shanghai in 2006, it encountered a problem that, until recently, was considered virtually impossible: nearly four miles above the earth, both engines of the big Airbus A330 shut down at the same time.
The engines quickly restarted and the pilots managed a safe landing. But the incident, along with similar ones before it, set off alarm bells throughout the industry because of the cause: ice inside the engines.
Modern jet engines long were thought to be impervious to internal icing. But airlines, regulators and weather scientists now think otherwise, and have been scrambling to figure out how to handle the hazard. Despite some progress, the shutdowns keep happening.
On Monday, the Federal Aviation Administration will propose new safety rules that are expected to apply eventually to about 1,200 widebody jetliners world-wide, including Boeing 747 jumbo jets. Pilots of those planes will be required to turn on engine anti-ice systems more frequently during descents, to reduce the chances of sudden shutdowns and to increase the likelihood that engines that quit will restart.


























my comment: I think that all the countries have to work to improve the technology for the security of the airplanes. In the picture we can see that is a worldwide problem. In our country, there are many problems with the airplanes because of the tower controllers, the bad technologies, and the bad administration of the government of the Argentinian aviation.
