Boeing says it has invited about 200 aviation professionals, including representatives from Virgin Australia, to its Renton facility in Washington State for a technical briefing on the 737 MAX due to be held on Wednesday, March 27.

The company said {in a|inside a|within a} statement on Monday (Australian time) the informational session for airline pilots, technical leaders and regulators was part of its “ ongoing effort to share more details about our plan for supporting the safe return of the 737 MAX to commercial service”.

“ {We had|There were} a productive session {this past|earlier this} Saturday and plan to reach all current and many future MAX operators and their home regulators, ” the Boeing statement said.

“ At the same time, we {continue to|always|carry on and} work closely with our customers and regulators on software and training updates {for the|for that|for your} 737 MAX. Boeing is paying for the development of these updates. ”

{Over the weekend|This past weekend}, Boeing and pilots from United States-based 737 MAX operators tested a software update being developed for the 737 MAX’ s anti-stall system in a simulator, {according to|based on|in accordance with} a report from the Reuters news agency.

The software update has been in development since a Lion Air 737 MAX 8 plunged into the sea just minutes after it took off from Jakarta in October 2018.

That incident, which killed all 189 people {on board|aboard|on side}, prompted the United States Federal Aviation Administration (FAA) to issue an emergency airworthiness directive (AD) on November 7 2018 to operators of the 737 MAX that called on them {to address|to deal with|to cope with} procedures in the event of pilots receiving erroneous angle of attack sensor information.

Boeing has said previously it expected to {roll out|turns out} a software update by April , with the FAA to mandate the update {with an|having an|by having an} airworthiness directive.

Asked about the weekend simulator sessions, a Boeing spokesperson would only say {in an|within an|in a} emailed statement to Australian Aviation : “ We have been engaging {with all|using|system} 737 MAX operators {and we are|and are|and that we are} continuing to schedule meetings to share information about our plans for supporting the 737 MAX fleet. ”

While there are no Australian operators of the 737 MAX, Virgin Australia has 40 of the type on order and due to receive its first 737 MAX 8 by the end of 2019. The airline is also scheduled {to take|to consider|for taking} delivery of the 737 MAX 10 in 2022 .

A Virgin Australia spokesperson said on Monday the airline had accepted the invitation to attend the Boeing session.

“ Virgin Australia will be sending two of its most senior flight operations team members to Seattle for an information session on the Boeing 737 MAX 8 aircraft, ” the spokesperson told Australian Aviation in an emailed statement.

“ We look {forward to|toward} hearing what Boeing {has to|needs to|must} say. ”

The spokesperson reiterated {it was|it had been|it absolutely was} still Virgin Australia’ s firm position that the airline would not receive any new aircraft into the fleet until completely satisfied with its safety.

Virgin Australia first stated its position in a statement on March 12, which said it was closely monitoring the situation and would {continue to|always|carry on and} work with Boeing, Australia’ s Civil Aviation Safety Authority (CASA), and other relevant authorities as more information became available.

“ Safety is Virgin Australia’ s {number one priority|most important|most critical}, ” the March 12 statement said.

The global 737 MAX {fleet of|number of} about 370 aircraft currently sits grounded following a second fatal accident involving the {type in|enter|key in} the past six months, when Ethiopian Airlines flight ET302 crashed shortly after takeoff from Addis Ababa.

The preliminary analysis of the flight data recorder (FDR) {from the|from your|through the} Ethiopian Airlines accident showed similarities with the Lion Air crash.

The investigations into the Lion Air tragedy considered the role of Manoeuvring Characteristics Augmentation System (MCAS) on the MAX, which was added as part of design changes to {compensate for|make up for} stall risk from the {installation of|installing of} larger engines further forward on the wing compared with previous 737 versions.

MCAS software tells the flight control system {to change|to improve|to alter} its Angle of Attack (AOA) downward if a stall risk is perceived. Pilots can override the system by manually adjusting the trim.

The preliminary report into the crash of Lion Air JT610 {by the|from the|with the} Indonesian authorities included references to a faulty sensor {linked to the|from the} MCAS which provided erroneous angle of attack data and repeatedly pushed the nose of the plane down. The result was a wrestling {match with|complement} the controls as the crew fought to compensate for the nose-down attitude.

{A report|A written report|A study} in The New York Times said {the software|the program|the application} update would modify the MCAS to take readings from two sensors on {any given|a} flight, compared to just one sensor under the existing operation. Should there be a meaningful disagreement between the readings, MCAS {would be|will be|can be} disabled.

During the enforced grounding of the 737 MAX by regulators around the world, Boeing {has been|continues to be|have been} postponing deliveries of the aircraft to its airline customers, leading to completed aircraft being parked around its facilities in Washington State and elsewhere.

Boeing 737 MAX operators {in the United States are|in the usa are|in america are} also sending their aircraft to storage facilities {while the|as the|even though the} grounding remains in place.

The United States Department of Transportation has also asked for an audit {of the|from the|in the} 737 MAX certification process undertaken {by the|from the|with the} FAA.

{The United States|The usa|America} Federal Bureau of Investigation (FBI) and federal prosecutors were also looking into the certification of the 737 MAX, The Seattle Times reported.
