FAA AD 2017-13-13 Boeing B737 Cracking

SUMMARY: We are adopting a new airworthiness directive (AD) for certain The Boeing Company Model 737-100, -200, -200C, -300, -400, and -500 series airplanes. This AD was prompted by reports of frame web cracking at certain locations. This AD requires repetitive inspections in certain locations of the frame web, and corrective action if necessary. We are issuing this AD to address the unsafe condition on these products.

FAA AD 2017-13-07 Airbus Model A319, A320, and A321 series airplanes

SUMMARY: We are adopting a new airworthiness directive (AD) for all Airbus Model A319, A320, and A321 series airplanes. This AD was prompted by a report that a main landing gear (MLG) door could not be closed due to rupture of the actuator fitting. This AD requires repetitive inspections for cracking of the MLG door actuator fitting and its components, and corrective actions if necessary. This AD also requires eventual replacement of all affected MLG door actuator fittings with new monoblock fittings, which would terminate the repetitive inspections. We are issuing this AD to address the unsafe condition on these products. HFEC and LFEC NDT inspections

MD-83 with U of M Mens Basketball team

“The Michigan men’s basketball team plane was involved in an accident Wednesday afternoon. After attempting to take off in high winds, takeoff was aborted and, after strong braking, the plane slide off runway. The plane sustained extensive damage but everyone on board was safely evacuated and is safe. The team is making alternate travel plans.”

1. The Plane Was Travelling About 150 MPH When It Skidded Off the Runway

Initial news reports weren’t able to put the whole situation into perspective.

Michigan coach John Beilein said that reporting that it’s a plane “skidding off the runway” didn’t paint the right picture. Instead, the plane was traveling extremely fast as it attempted to get off of the runway, Beilein said.

It wasn’t just a plane skidding off a runway. It was full going, 150 miles an hour, we can’t stop. And our kids got — thank goodness the plane didn’t flip. All kinds of things could have happened once we got off the plane and looked.

He said that crews aboard the plan acted quickly to ensure safety, but it was a very scary situation. Thankfully, the plane didn’t strike any large objects or slide any further, otherwise the crash may have had fatal results.


2. The Plane Malfunctioned Because of an Equipment Issue

The National Transportation Safety Board issued an update to the incident March 22 and said that the cause seems to be an equipment malfunction.

The statement said that while probable cause and a conclusion hasn’t yet determined, preliminary information and details have been found.

The NTSB said that a post-accident examination found that the “right elevator” on the plane was jammed into a “trailing edge-down position.” Further inspection showed that the elevator on the plane was damaged and restricted movement.

When investigators tried to move the elevator surfaces by hand, the left elevator moved normally, but the right elevator was jammed in a trailing edge-down position (airplane nose down). Upon further inspection, the right elevator geared tab inboard pushrod linkage was found damaged which restricted movement of the right elevator surface but allowed movement of the control tab. After the damaged components were removed, the elevator could be moved by hand.

On airplanes, elevators help control the pitch on the aircraft and provide measurements to how far the nose of a plane is tilted up or down.

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

Story by Stephen Pope Yesterday at 12:13pm

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.”
