Tag Archives: Non-Destructive Testing

Nondestructive testing or Non-destructive testing (NDT) is a wide group of analysis techniques used in science and industry to evaluate the properties of a material, component or system without causing damage. The terms Nondestructive examination (NDE), Nondestructive inspection (NDI), and Nondestructive evaluation (NDE) are also commonly used to describe this technology. Because NDT does not permanently alter the article being inspected, it is a highly valuable technique that can save both money and time in product evaluation, troubleshooting, and research. Common NDT methods include ultrasonic, magnetic-particle, liquid penetrant, radiographic, remote visual inspection (RVI), eddy-current testing, and low coherence interferometry. NDT is commonly used in forensic engineering, mechanical engineering, petroleum engineering, electrical engineering, civil engineering, systems engineering, aeronautical engineering, medicine, and art.

FAA AD Boeing Company Model 767-200 and -300 series airplanes

SUMMARY: We are adopting a new airworthiness directive (AD) for all The Boeing Company Model 767-200 and -300 series airplanes. This AD was prompted by an evaluation by the design approval holder (DAH) indicating that the frame-to-floor-beam joints and frames common to shear ties at certain locations of fuselage structure are subject to widespread fatigue damage (WFD). This AD requires inspections for cracking of certain frame inner chords and webs common to the floor beam joint and at frames common to the shear ties at certain sections, and corrective action if necessary. We are issuing this AD to address the unsafe condition on these products.

FAA AD Airbus Model A300 series airplanes.

SUMMARY: We are adopting a new airworthiness directive (AD) for all Airbus Model A300 series airplanes. This AD was prompted by an evaluation by the design approval holder (DAH) that indicates that a section of the wing and aft fuselage is subject to widespread fatigue damage (WFD). This AD requires an inspection to determine if certain modifications have been done. We are issuing this AD to address the unsafe condition on these products

FAA AD Sikorsky Aircraft Corporation (Sikorsky) Model S-92A helicopters

We are publishing a new airworthiness directive (AD) for Sikorsky Aircraft Corporation (Sikorsky) Model S-92A helicopters. This AD requires inspecting certain bearings. This AD is prompted by reports of failed bearings with subsequent loss of tail rotor (TR) control. The actions of this AD are intended to address an unsafe condition on these helicopters.

Aviation Groups Urge NTSB to Tell the Whole Story on GA Safety

Aircraft crash - FAR Part 91

 

21 aviation associations send letter criticizing the Safety Board for its role in a skewed NBC News report on flying safety.

 

In a September 23 letter to the National Transportation Safety Board, 21 general aviation associations wrote to voice their displeasure with the panel’s apparent role in a recent NBC Nightly News report on an aircraft accident that portrayed personal flying as a highly risky activity. The groups are urging the NTSB to “publicly convey that general aviation is one of the safest modes of transportation in the United States.”

“Given the hundreds of thousands of flight hours each year it is understandable that aviation accidents receive significant media attention because they are so infrequent given the enormous amount of private and business flying in the United States,” the groups said in the letter. “The media’s reporting of general aviation accidents should be balanced just as we believe NTSB accident investigations should be thorough and rely solely on facts and not speculation. We believe the NTSB has an inherent responsibility to help provide media outlets with a comprehensive view of safety trends and outline the improvements in general aviation safety over the years.”

When the NTSB first put general aviation safety on its Most Wanted List of safety improvements in 2011, the industry applauded. Now, the GA groups appear to be growing weary of the bull’s-eye that this label puts on aviation’s back.
The NBC report noted that loss of control is the No. 1 cause of fatal general aviation accidents and quoted statistics supplied to the network by the NTSB. The piece failed, however, to note that GA safety has been improving over the years and in 2014 recorded the lowest fatal accident rate ever.
“We, as a responsible industry, do everything within our power to ensure that safety remains our top priority and we must continue to work together to manage risk in general aviation,” the aviation groups, which included AOPA, EAA and NBAA, wrote. “We must not let media reports like these discredit the hard work and gains we have all made together, and we encourage the NTSB to help set the record straight.”
