Boeing CEO Dennis A. Muilenburg issued the following statement in response to its 737 Max software, production:


eTN Chatroom for Readers (join us)

As we work closely with customers and global regulators to return the 737 MAX to service, we continue to be driven by our enduring values, with a focus on safety, integrity and quality in all we do.

We now know that the recent Lion Air Flight 610 and Ethiopian Airlines Flight 302 accidents were caused by a chain of events, with a common chain link being erroneous activation of the aircraft’s MCAS function. We have the responsibility to eliminate this risk, and we know how to do it. As part of this effort, we’re making progress on the 737 MAX software update that will prevent accidents like these from ever happening again. Teams are working tirelessly, advancing and testing the software, conducting non-advocate reviews, and engaging regulators and customers worldwide as we proceed to final certification. I recently had the opportunity to experience the software update performing safely in action during a 737 MAX 7 demo flight.  We’re also finalizing new pilot training courses and supplementary educational material for our global MAX customers. This progress is the result of our comprehensive, disciplined approach and taking the time necessary to get it right.

As we continue to work through these steps, we’re adjusting the 737 production system temporarily to accommodate the pause in MAX deliveries, allowing us to prioritize additional resources to focus on software certification and returning the MAX to flight. We have decided to temporarily move from a production rate of 52 airplanes per month to 42 airplanes per month starting in mid-April.

At a production rate of 42 airplanes per month, the 737 program and related production teams will maintain their current employment levels while we continue to invest in the broader health and quality of our production system and supply chain.

We are coordinating closely with our customers as we work through plans to mitigate the impact of this adjustment. We will also work directly with our suppliers on their production plans to minimize operational disruption and financial impact of the production rate change.

In light of our commitment to continuous improvement and our determination to always make a safe industry even safer, I’ve asked the Boeing Board of Directors to establish a committee to review our company-wide policies and processes for the design and development of the airplanes we build.  The committee will confirm the effectiveness of our policies and processes for assuring the highest level of safety on the 737-MAX program, as well as our other airplane programs, and recommend improvements to our policies and procedures.

The committee members will be Adm. Edmund P. Giambastiani, Jr., (Ret.), former vice chairman, U.S. Joint Chiefs of Staff, who will serve as the committee’s chair; Robert A. Bradway, chairman and CEO of Amgen, Inc.; Lynn J. Good, chairman, president and CEO of the Duke Energy Corporation; and Edward M. Liddy, former chairman and CEO of the Allstate Corporation, all members of the company’s board. These individuals have been selected to serve on this committee because of their collective and extensive experiences that include leadership roles in corporate, regulated industries and government entities where safety and the safety of lives is paramount.

Safety is our responsibility, and we own it. When the MAX returns to the skies, we’ve promised our airline customers and their passengers and crews that it will be as safe as any airplane ever to fly. Our continued disciplined approach is the right decision for our employees, customers, supplier partners and other stakeholders as we work with global regulators and customers to return the 737 MAX fleet to service and deliver on our commitments to all of our stakeholders.

Xtra Aerospace in Florida also responsible for Boeing 737 Max crash?

by

Our purpose is to ensure each flight is safe and cost-effective every day. This is the message on the Xtra Aerospace website. The Xtra Aerospace states their maintenance division can provide optimal maintenance to all of the unique aviation needs.

Xtra Aerospace may have been very much off on this goal when in Indonesia a Lion Air Boeing 737 MAX crashed after it was repaired in a U.S. aircraft maintenance facility and the so-called angle-of-attack sensor was replaced. This sensor sent erroneous signals causing repeated nose-down movements on the Oct. 29 flight that pilots struggled with until the Boeing Max plunged into the Java Sea. Everyone on board, 189 people were killed.

XTRA Aerospace is an FAA/EASA/ANAC certified repair station located in Miramar, Florida, USA.

Documents obtained by Bloomberg News show the repair station, XTRA Aerospace Inc. in Miramar, Fla., had worked on the sensor. It was later installed on the Lion Air plane on Oct. 28 in Bali, after pilots had reported problems with instruments displaying speed and altitude. There’s no indication the Florida shop did maintenance on the Ethiopian jet’s device, according to Bloomberg.

Xtra Aerospace states: ” We specialize in the repair of instruments, radio & mechanical/electrical accessories. XTRA offers extensive capabilities servicing the A300, A320 family/A330/A340 and Boeing 737 thru 777. We are proud to serve the world’s top airlines and suppliers with one goal… complete customer satisfaction.

XTRA Aerospace welcomes the U.S. Government. XTRA is DD2345 certified to obtain military critical technical data. XTRA’s cage code is 5FWE2 and we look forward to helping you with all your sourcing and repair needs.”

U.S. teams assisting the Indonesian investigation reviewed the work by the company to ensure that there weren’t additional angle-of-attack sensors in the supply chain with defects, said a person familiar with the work. They didn’t find any evidence of systemic issues on other sensors the company may have worked on.

Bloomberg states in their article:

“Much of the concern by regulators and lawmakers after the Lion Air and Ethiopian Airlines crashes has focused on Boeing’s design of the Maneuvering Characteristics Augmentation System, or MCAS, which was programmed to push down a plane’s nose to help prevent aerodynamic stalls in some situations. But the preliminary report by Indonesia on the Lion Air crash shows that maintenance and pilot actions are also being reviewed.

It’s common for licensed repair stations to overhaul older parts so they can be resold, said John Goglia, a former member of the NTSB who earlier worked as an airline mechanic. Airlines can save money buying used parts and U.S. regulations require that the parts meet legal standards, Goglia said.

If the sensor was repaired at XTRA Aerospace, “it would have to go through what the manual says to overhaul it,” he said. “That means all the steps.”

The Indonesian preliminary report doesn’t say what went wrong with the device but indicates that the plane’s maintenance is a subject of the investigation.”

The Ethiopian Airlines 737 Max that crashed on March 10 also apparently had issues with the same type of sensor, which triggered a safety system on the plane that was driving down the plane’s nose, according to people familiar with the accident. In that case, investigators are still attempting to locate one of the sensors to help determine why it malfunctioned.

Confirmed: Auto anti-stall system on before Ethiopian Max jet crash

by

It has been confirmed that investigators have determined the automatic anti-stall system as activated before the Ethiopian Airlines Boeing 737 Max jet crash.

This initial determination is based on information from the aircraft’s data and voice recorders, which shows that the malfunctioning automated system may be responsible for the deadly March 10 crash.

This preliminary determination was made known during a briefing at the US Federal Aviation Administration (FAA) yesterday. It is also known that the auto anti-stall system was activated on the Indonesian Lion Air 737 Max jet crash.

The preliminary findings could be revised, but right now they point to the system, called MCAS (or Maneuvering Characteristics Augmentation System) as the potential cause of both crashes. Regulators say the Ethiopian Airlines Max jet followed a similar flight path to the Lion Air flight, including erratic climbs and descents before crashing minutes after takeoff.

The MCAS system is designed to automatically point the nose of the jets down if it senses potential for a loss of lift, or aerodynamic stall. Aircraft can lose lift from the wings and fall from the sky if the nose points too high. The system also makes the Max fly similarly to older generations of Boeing’s 737, negating the need for a lot of added pilot training.

Boeing is working on a software update to the auto anti-stall system so that the nose will point down only once instead of around 21 times as happened in the Lion Air crash making it easier for pilots to override it.

Ethiopian officials are expected to release their preliminary report soon.

The 737 Max 8 has been grounded worldwide due to the crashes as Boeing works on an update to its software to make the planes safer.

Ethiopian Airlines refutes wrong reporting of the New York Times

by

Ethiopian Airlines would like to refute the following wrong reporting of the New York Times titled “Ethiopian Airlines Had a Max 8 Simulator, but Pilot on Doomed Flight Didn’t Receive Training”

Ethiopian Airlines, one of the safest and most dependable airlines in the world, is pleased to confirm that Ethiopian pilots have completed the Boeing recommended and FAA approved differences training from the B-737 NG aircraft to the B-737 MAX aircraft before the phase in of the B-737-800 MAX fleet to the Ethiopian operation and before they start flying the B-737-800 MAX.

The pilots had also been made aware of, and well briefed on the Emergency Airworthiness Directive issued by the FAA following the Lion Air accident. The content of the airworthiness directive has also been well incorporated in all pilot training manuals, operational procedures and working manuals.

The B-737 MAX full flight simulators is not designed to simulate the Maneuvering Characteristics Augmentation System (MCAS) problems.

Ethiopia Airlines urges all concerned to refrain from making uninformed, incorrect, irresponsible and misleading statements during the period of the accident investigation. International regulations require all stakeholders to wait patiently for the final result of the investigation.

Pilots frantic search for fix while Boeing Max8 went down

by

Ethiopian Airlines and Lions Air most likely have the same deadly scenario accordsidng to a report Reuters today reported about the 31-year-old Lions’ Air captain was at the controls of Lion Air flight JT610 flying the Boeing Max 8 when the nearly new jet took off from Jakarta. The first officer was handling the radio, according to a preliminary report issued in November.

The report said:

The pilots of a doomed Lion Air Boeing 737 MAX scoured a handbook as they struggled to understand why the jet was lurching downwards but ran out of time before it hit the water, three people with knowledge of the cockpit voice recorder contents said.

The investigation into the crash, which killed all 189 people on board in October, has taken on new relevance as the U.S. Federal Aviation Administration (FAA) and other regulators grounded the model last week after a second deadly accident in Ethiopia.

Investigators examining the Indonesian crash are considering how a computer ordered the plane to dive in response to data from a faulty sensor and whether the pilots had enough training to respond appropriately to the emergency, among other factors.

It is the first time the voice recorder contents from the Lion Air flight have been made public. The three sources discussed them on condition of anonymity.

Reuters did not have access to the recording or transcript.

A Lion Air spokesman said all data and information had been given to investigators and declined to comment further.

Just two minutes into the flight, the first officer reported a “flight control problem” to air traffic control and said the pilots intended to maintain an altitude of 5,000 feet, the November report said.

The first officer did not specify the problem, but one source said airspeed was mentioned on the cockpit voice recording, and a second source said an indicator showed a problem on the captain’s display but not the first officer’s.

The captain asked the first officer to check the quick reference handbook, which contains checklists for abnormal events, the first source said.

For the next nine minutes, the jet warned pilots it was in a stall and pushed the nose down in response, the report showed. A stall is when the airflow over a plane’s wings is too weak to generate lift and keep it flying.

The captain fought to climb, but the computer, still incorrectly sensing a stall, continued to push the nose down using the plane’s trim system. Normally, trim adjusts an aircraft’s control surfaces to ensure it flies straight and level.

“They didn’t seem to know the trim was moving down,” the third source said. “They thought only about airspeed and altitude. That was the only thing they talked about.”

Boeing Co declined to comment on Wednesday because the investigation was ongoing.

The manufacturer has said there is a documented procedure to handle the situation. A different crew on the same plane the evening before encountered the same problem but solved it after running through three checklists, according to the November report.

But they did not pass on all of the information about the problems they encountered to the next crew, the report said.

The pilots of JT610 remained calm for most of the flight, the three sources said. Near the end, the captain asked the first officer to fly while he checked the manual for a solution.

About one minute before the plane disappeared from radar, the captain asked air traffic control to clear other traffic below 3,000 feet and requested an altitude of “five thou”, or 5,000 feet, which was approved, the preliminary report said.

As the 31-year-old captain tried in vain to find the right procedure in the handbook, the 41-year-old first officer was unable to control the plane, two of the sources said.

The flight data recorder shows the final control column inputs from the first officer were weaker than the ones made earlier by the captain.

“It is like a test where there are 100 questions and when the time is up you have only answered 75,” the third source said. “So you panic. It is a time-out condition.”

The Indian-born captain was silent at the end, all three sources said, while the Indonesian first officer said “Allahu Akbar”, or “God is greatest”, a common Arabic phrase in the majority-Muslim country that can be used to express excitement, shock, praise or distress.

French air accident investigation agency BEA said on Tuesday the flight data recorder in the Ethiopian crash that killed 157 people showed “clear similarities” to the Lion Air disaster. Since the Lion Air crash, Boeing has been pursuing a software upgrade to change how much authority is given to the Maneuvering Characteristics Augmentation System, or MCAS, a new anti-stall system developed for the 737 MAX.

The cause of the Lion Air crash has not been determined, but the preliminary report mentioned the Boeing system, a faulty, recently replaced sensor and the airline’s maintenance and training.

On the same aircraft the evening before the crash, a captain at Lion Air’s full-service sister carrier, Batik Air, was riding along in the cockpit and solved the similar flight control problems, two of the sources said. His presence on that flight, first reported by Bloomberg, was not disclosed in the preliminary report.

The report also did not include data from the cockpit voice recorder, which was not recovered from the ocean floor until January.

Soerjanto Tjahjono, head of Indonesian investigation agency KNKT, said last week the report could be released in July or August as authorities attempted to speed up the inquiry in the wake of the Ethiopian crash.

On Wednesday, he declined to comment on the cockpit voice recorder contents, saying they had not been made public.
