The National Transportation Safety Board (NTSB) has released information from the investigation into the circumstances of the second-worst airline disaster in U.S. history that sheds new light onto its causes. American Airlines Flight 587 crashed into a residential suburb of New York City shortly after takeoff from John F. Kennedy Intl. Airport on November 12, 2001. Flight 587 was operated on an Airbus A300-605R, a variant of the A300-600 series aircraft, the second most popular model of commercial aircraft behind Boeing's 757. According to the NTSB, a design flaw in the rudder of Airbus A300-600 series aircraft makes the rudder pedals extremely sensitive at high speeds. Pilots who are unaware of this sensitivity and apply too much force can unintentionally cause the rudder panel on the jet's tail to rock violently back and forth, which, according to the NTSB's analysis, can create enough force to break a jet apart midair. A rudder is a movable panel on the fin that rises from the tail of a jet, and it is designed to keep a jet pointed straight in a cross wind or while flying on one engine.
The National Transportation Safety Board (NTSB) issued two recommendations yesterday to the U.S. Coast Guard regarding the use of wireless devices during the operation of Coast Guard watercraft. The recommendations decry a need for regulations governing such use amongst both the Coast Guard and the maritime industry in an effort to prevent the consequences of distraction.
In the past five years, the railroad crossing between Nagle Avenue, Avondale Avenue and the Northwest Highway has seen six accidents involving trains and automobiles, and in the wake of several such collisions in Chicago this year, steps are being taken to make the crossing safer - a trend that will hopefully extend to the city's other hazardous crossings.
