In casi come questo, quando c'è una riattaccata di mezzo – e dopo gli incidenti di Flydubai in Russia ed Amazon Air in Texas, oramai penso sempre all'errore di condotta dovuto all'illusione somatogravica...

Non credo abbia nulla a che fare con i problemi del MAX.

Credo abbia nulla a che fare col MAX, direi più un problema di errore umano e di macchina obsoleta. Mi è giunta all'orecchio anche di una compagnia nostrana che ha avuto seri problemi durante un GA in IMC...

ma è un problema che affligge solo la versione 1B del motore altrimenti sarebbero coinvolti pure airbus e comac. Vero che solo il 737 presenta una gondola di dimensioni ridotte per adattarsi all'altezza del carrello...

NTSB sanctions Boeing for sharing unauthorized Alaska 1282 information during media briefing
Boeing retains party status, but NTSB limits its access to the investigative information after comments in advance of the Farnborough International Airshow.

The National Transportation Safety Board late Wednesday offered a sharp rebuke of Boeing after learning the company held a media event on June 25 with around four dozen U.S. and international journalists inside its Renton, Washington factory, which included brief comments about Alaska Airlines 1282.

Boeing is a party to the NTSB’s investigation of the Jan. 5 accident, which occurred when a plug exit violently departed a newly built 737 Max 9 soon after takeoff from Portland International Airport in Oregon. Preliminary information indicates that the bolts designed to hold the exit in place were not on the airplane when it left Boeing’s factory in Renton.

“During a media briefing Tuesday about quality improvements at Boeing Commercial Airplanes, a Boeing executive provided investigative information and gave an analysis of factual information previously released,” the board said in a statement to The Air Current. “Both of these actions are prohibited by the party agreement that Boeing signed when it was offered party status by the NTSB at the start of the investigation. As a party to many NTSB investigations over the past decades, few entities know the rules better than Boeing.”

In an unusual step, the NTSB is taking action against the plane maker for its comments, including removing its access to the docket of information gathered through the investigation. The NTSB will subpoena any relevant records from Boeing, and the plane maker will not be given the opportunity to ask questions of witnesses at the planned August hearing into the accident. Boeing remains a party to the investigation.

Additionally, the NTSB said, “Given that Boeing is under investigation by the U.S. Department of Justice in relation to its Deferred Prosecution Agreement stemming from Boeing’s interactions with the FAA prior to the Boeing MAX fatalities, the NTSB will be coordinating with the DOJ Fraud Division to provide details about Boeing’s recent unauthorized investigative information releases in the 737 MAX 9 door plug investigation.”

The party system allows technical experts — such as the manufacturer of an aircraft involved in an accident — to help the NTSB gather and develop the facts around an investigation. Internationally agreed-upon rules strictly govern the conduct of parties, including limiting what information they may share publicly while the investigation is ongoing.

NTSB chair Jennifer Homendy told TAC that the board was not notified in advance about the media event, which Boeing described to journalists as “a full day dedicated to safety and quality” at the site of the manufacturing breakdown that led to Alaska 1282. Coverage of the event has not yet been published, as Boeing imposed an embargo on attending publications, including The Air Current, which lifts on June 27.

Embargoes are common practice during media briefings in the pre-air show run up in order to provide journalists with sufficient time to prepare coverage on the many topics that are discussed. The U.K.’s Farnborough International Airshow begins July 22.

“After the NTSB learned of the unauthorized release of information and requested additional information about the press briefing, Boeing provided the agency with a transcript. The transcript revealed that Boeing provided non-public investigative information to the news media that NTSB had not verified or authorized for release. In addition, Boeing offered opinions and analysis on factors it suggested were causal to the accident,” said the NTSB.

A Boeing spokesperson told TAC: “As we continue to take responsibility and work transparently, we conducted an in-depth briefing on our Safety & Quality Plan and shared context on the lessons we have learned from the January 5 accident. We deeply regret that some of our comments, intended to make clear our responsibility in the accident and explain the actions we are taking, overstepped the NTSB’s role as the source of investigative information. We apologize to the NTSB and stand ready to answer any questions as the agency continues its investigation.”

The rebuke comes just one day after NTSB Chair Jennifer Homendy made a damning indictment of Norfolk Southern during a public board meeting to determine the probable cause of a Feb. 3, 2023 train derailment in East Palestine, Ohio. The NTSB found that a defective wheel bearing on a Norfolk Southern rail car caused the derailment, and that the decision by the local incident commander three days later to conduct a vent and burn of the contents of tank cars carrying hazardous materials was based on incomplete and misleading information provided by Norfolk Southern officials and contractors.

In her closing remarks at the board meeting, Homendy said that Norfolk Southern on numerous occasions delayed or failed to provide critical information to investigators and violated regulations governing evidence collection by manufacturing its own evidence outside of the NTSB investigative process. Homendy called Norfolk Southern’s actions “unconscionable” and said she was initiating an internal effort to ensure that the agency and its personnel are adequately protected from undue interference with a federal investigation.

“I want everyone who works with the NTSB — on current and future investigations — to understand this: we are impervious to anything but the truth,” she declared.

The NTSB said this is the second time Boeing has violated party rules in the Alaska 1282 investigation. In a Congressional hearing in March, Homendy chastised Boeing for its conduct, particularly around its delay in handing over information surrounding work done on the plug door exit by Boeing and Spirit AeroSystems employees that ultimately caused it to depart in flight. Since then, Boeing has confirmed that documentation of that work being done does not exist.

Si intravedono le prime manovre correttive.
Certo, dopo anni di magra viene da chiedersi da dove li possano tirare fuori 4,7 miliardi di dollari per l'acquisto ($8,3mld considerando anche le passività da accollarsi).

Boeing Agrees to Buy Spirit AeroSystems, a Longtime Supplier
The multibillion-dollar deal will reverse a decision the plane maker made two decades ago to outsource production of key parts to independent suppliers.
July 1, 2024, 12:53 a.m. ET
By Niraj Chokshi

Boeing said on Monday that it had agreed to buy a major supplier, Spirit AeroSystems, ending a nearly two-decade experiment in outsourcing production of major components of its commercial planes, including the body of the 737 Max and parts of the 767, 777 and 787.

In buying Spirit, Boeing hopes to stem quality problems that have plagued the supplier in recent years. While it already has significant influence over Spirit, Boeing will more easily be able to monitor and change production practices by owning the business outright. Boeing has taken internal steps to improve quality, too, after a harrowing incident in which a panel blew out of one of its planes on a flight in January.

“By reintegrating Spirit,” Boeing’s chief executive, Dave Calhoun, said in a statement, the company “can fully align” its production and safety systems with its work force.

The deal, which was widely expected, was valued at $4.7 billion in stock or $8.3 billion including Spirit’s debt. It must be approved by regulators and Spirit’s shareholders to be completed. Boeing will also spin off portions of Spirit to Airbus, its European rival, as part of the transaction. Boeing said its acquisition of Spirit is expected to close by the middle of next year.

The purchase represents a strategic reversal for Boeing, which started relying more extensively on independent suppliers in the 2000s to cut costs and raise profits. Spirit was created during that outsourcing drive in 2005, when Boeing sold a division in Wichita, Kan., and operations in Oklahoma.

Besides its work for Boeing, Spirit makes components for aerospace companies including Airbus, Bombardier, Lockheed Martin, Northrop Grumman and Rolls-Royce. Boeing accounted for 64 percent of Spirit’s net revenue last year, while Airbus accounted for 19 percent. Boeing offered to buy Spirit at $37.25 per share, a 30 percent premium over Spirit’s stock price at the end of February before the two companies announced they were in talks.

Spirit’s quality problems led to a leadership shake-up last fall in which Patrick Shanahan, a former Boeing executive and a former senior Defense Department official, became chief executive. At Boeing, Mr. Shanahan was regarded as an accomplished executive who could quickly turn around troubled programs or units. He is now a leading candidate to replace Mr. Calhoun, who plans to step down by the end of this year.

But Boeing has its own quality problems. The company has faced intense scrutiny since the Jan. 5 incident in which a panel on a 737 Max 9 blew out during an Alaska Airlines flight shortly after takeoff. The panel, known as a door plug, covers the gap left by an unneeded emergency exit.

News of the Spirit agreement came hours after a report that federal officials planned to offer Boeing a plea deal in a fraud case related to a pair of fatal crashes more than five years ago in which 346 people died.

While no serious injuries were reported in the January episode, the consequences could have been far more severe had the panel blown out at a higher altitude when passengers may have been moving around the cabin. The National Transportation Safety Board has said the plane appeared to have left a Boeing factory without the bolts needed to secure the plug, and the company has said it cannot find documentation of that work. The plug had been removed so that workers for Spirit could perform repairs on nearby.

In response, Boeing has made several changes in recent months. It said it has expanded training, simplified plans and processes and increased inspections at its 737 factory in Renton, Wash., as well as at Spirit. Since March, it has also stopped accepting 737 bodies, or fuselages, from Spirit that do not fully meet Boeing’s standards. It had previously tolerated some flaws that could be fixed later, in the interest of keeping production moving.

That change has yielded significant benefits, Elizabeth Lund, a top Boeing quality executive, told reporters at the factory last week. Significantly fewer major defects need to be fixed by Boeing now, she said, and the company is able to assemble the Max much more quickly once bodies arrive in Renton.

Boeing has also said it aims to reduce its practice of performing manufacturing tasks out of sequence, also known as traveled work. Some traveled work is considered necessary, but too much can disrupt the complicated process of making airplanes, possibly contributing to defects and poor workmanship.

In the briefing with reporters, Ms. Lund also shared new detail on how the plane involved in the January flight left the plant without the door plug fully secured. After the plug was removed to make the repairs nearby, a crew readied the plane to be moved outside, putting the plug back in place without its bolts, which was not that team’s responsibility, she said.

Ms. Lund’s disclosure of new information, along with other comments in that briefing, elicited the fury of the N.T.S.B., which sharply rebuked Boeing for violating rules about speaking about an ongoing investigation.

Boeing apologized to the safety board, acknowledging that it “overstepped the N.T.S.B.’s role as the source of investigative information.”
