NTSB Finds Fatigue Cracking In American Airlines Engine

Federal safety investigators say an engine disk that broke apart just before an American Airlines plane took off at Chicago O’Hare International Airport last week shows signs of fatigue cracking. “A high-pressure turbine disk in the Boeing 767’s right engine broke into four pieces, which shot out of the engine’s housing,” the Associated Press reported, citing the National Transportation Safety Board’s preliminary report of the Oct. 28 incident. An analysis of the fragmented disk, 90 percent of which investigators have recovered, showed evidence of an irregularity where the fatigue cracking began, the NTSB said. Investigators haven’t determined what precisely caused ... Read More

Indiana considers tougher private-bus safety laws in wake of deadly church bus crash

A new bill that would hold privately owned and operated passenger buses in Indiana to some of the same safety standards as their commercial counterparts moved to the state Senate for consideration. The measure, designed to close a loophole that permits potentially dangerous privately owned buses to operate within the state, was introduced after the July 26 church bus crash in Indianapolis that killed three people and an unborn child and injured more than two dozen others. Senate Bill 238, which unanimously passed a Senate transportation committee vote last week, would require privately owned buses to submit proof of vehicle ... Read More

Firefighter won’t be charged in runway death of Asiana crash survivor

SAN FRANCISCO — A firefighter facing potential criminal charges for accidentally running over and killing a plane crash survivor will not be charged for the girl’s death, San Mateo County’s District Attorney announced.

The Boeing 777 broke apart on impact and burst into flames. The crash injured 181 of the 307 people aboard, 12 of them critically. Three students, including Ms. Ye and her close friend Wang Linjia, lost their lives. Ms. Ye was one ... Read More

More Asiana crash survivors file complaints against Boeing alleging mechanical deficiencies

Six personal-injury lawsuits have been filed against Boeing by Asiana passengers who allege the aircraft manufacturer failed to install a low-airspeed warning system in some of its airplane models, including the 777 that crash-landed at San Francisco International Airport July 6. The lawsuits, which were filed in Boeing’s home state of Illinois, claim that the company knew of several previous incidents on Boeing airplanes in which a low-speed warning failed to alert pilots, but neglected to address the problem in its 777 models. The Asiana 214 crash killed two teenage girls. A third teenage girl was thrown from the plane ... Read More

Private buses bound to few safety rules and standards

Passengers who use privately owned buses, such as those owned and operated by churches, should know that the vehicles are not bound to the same federal and state safety requirements that commercial and school buses must meet. The problem of allowing buses that don’t fall under the same strict oversight to transport passengers was underscored recently by the crash of a church-owned bus that sped off an Indiana interstate and crashed July 27, killing three adults and an unborn child. Dozens of other passengers were injured in the crash, some critically. The bus, owned and operated by Colonial Hill Baptist ... Read More

Authorities investigating deadly Indiana church bus crash face regulatory shortfalls

INDIANAPOLIS, Ind. — Investigators say that it may take a few more days to determine what caused the driver of a church bus to lose control of the vehicle and crash as he exited the highway. The July 26 crash killed three people and an unborn child and injured 26 others, some critically. The bus, owned and operated by Colonial Hill Baptist Church in Indianapolis, was carrying 37 passengers, mostly church teens who were returning home from a teen church camp in Michigan. The driver, Dennis Maurer, 66, who was employed by the church to drive the bus, careened down ... Read More
