Joint Authorities Technical Review (JATR) Panel to Deliver Findings in Coming Weeks.
The Joint Authorities Technical Review (JATR) panel is taking additional time to finish documenting its work. We expect the group to submit its observations, findings, and recommendations in the coming weeks.
Chaired by former National Transportation Safety Board Chairman Christopher A. Hart, the JATR is comprised of technical safety experts from nine civil aviation authorities worldwide, as well as the FAA and NASA. The team received extensive overviews and engaged in subsequent discussions about the design, certification, regulations, compliance, training, and Organization Designation Authorization activities associated with the 737 MAX.
The JATR’s focus on the certification of the aircraft is separate from the ongoing efforts to safely return the aircraft to flight. The FAA continues to follow a thorough process, not a prescribed timeline, for returning the aircraft to passenger service. While the agency’s certification processes are well-established and have consistently produced safe aircraft designs, we welcome the scrutiny from these experts and look forward to their findings.
We will carefully review all recommendations and will incorporate any changes that would improve our certification activities.
6/26/2019 4:45 p.m. Update
The FAA is following a thorough process, not a prescribed timeline, for returning the Boeing 737 Max to passenger service. The FAA will lift the aircraft’s prohibition order when we deem it is safe to do so. We continue to evaluate Boeing’s software modification to the MCAS and we are still developing necessary training requirements. We also are responding to recommendations received from the Technical Advisory Board (TAB). The TAB is an independent review panel we have asked to review our work regarding 737 Max return to service.
On the most recent issue, the FAA’s process is designed to discover and highlight potential risks. The FAA recently found a potential risk that Boeing must mitigate.
Boeing has informed the FAA that certain 737NG and 737MAX leading edge slat tracks may have been improperly manufactured and may not meet all applicable regulatory requirements for strength and durability.
Following an investigation conducted by Boeing and the FAA Certificate Management Office (CMO), we have determined that up to 148 parts manufactured by a Boeing sub-tier supplier are affected. Boeing has identified groups of both 737NG and 737MAX airplane serial numbers on which these suspect parts may have been installed. 32 NG and 33 MAX are affected in the U.S. Affected worldwide fleet are 133 NG and 179 MAX aircraft.
The affected parts may be susceptible to premature failure or cracks resulting from the improper manufacturing process. Although a complete failure of a leading edge slat track would not result in the loss of the aircraft, a risk remains that a failed part could lead to aircraft damage in flight.
The FAA will issue an Airworthiness Directive to mandate Boeing's service actions to identify and remove the discrepant parts from service. Operators of affected aircraft are required to perform this action within 10 days. The FAA today also alerted international civil aviation authorities of this condition and required actions.
FAA Acting Administrator Dan Elwell's Closing Remarks at Directorates General Meeting
Thanks for joining us. Today’s meeting was both comprehensive and constructive. While the tragic circumstances that brought all of us together might be considered extraordinary—there is nothing extraordinary about the level of commitment to safety shared by all of us. Our sense of mission—that makes aviation the safest form of transportation—runs strong and deep, and binds all of us. If not in one meeting in Ft. Worth, we are comparing notes in symposiums around the world, we’re in web-based conferences, or we simply pick up the phone.
So, let me give you a short recap of what we covered today:
- How the FAA responded to the MAX accidents and how we’re supporting the two international accident investigations
- How we plan to certify Boeing’s MCAS changes and how we’ve been sharing information with all the regulators here.
- The latest status on the Technical Advisory Board, or TAB, which is reviewing Boeing’s MCAS software update and system safety assessment. As you know, the TAB is tasked with identifying any issues where further investigation is recommended before we approve the MCAS design change.
- Details of the Boeing’s proposed changes to the MAX – both to the flight control system and pilot training
- A review of the technical steps and sequence of events that we anticipate would be involved in ungrounding the MAX fleet here in the United States
- A discussion of international considerations for returning the MAX to service outside the United States
What happens next is that, here in the U.S., we await Boeing’s completed for changes to the MAX. Once received we perform our final risk assessments and analyses, taking into account findings of the TAB and any information we receive from our international counterparts. We’ll also take part in test flights of a modified 737 MAX and weigh all the information together before making the decision to return the aircraft to service.
Internationally, each country has to make its own decisions, but the FAA will make available to our counterparts all that we have learned, all that we have done, and all of our assistance under our International Civil Aviation Organization commitments.
As all of us work through this rigorous process, we will continue to be transparent and exchange all that we know and all that we do –to strengthen the public’s confidence that the aircraft will meet the highest safety standards.
FAA Acting Administrator Dan Elwell's Opening Remarks at Directorates General Meeting
Good afternoon and welcome to the FAA’s Southwest Regional office here in Fort Worth. As you know, tomorrow we’ll be meeting with dozens of regulators from across the globe to discuss our ongoing efforts aimed at getting the Boeing 737 MAX back into service.
We’ll be sharing with them the safety analysis that will form the basis for our return-to-service decision process here in the United States, and we’ll offer the FAA’s assistance in helping them with their individual decisions on returning the aircraft to service in their countries. We’ll also welcome their feedback to help us with our shared goal of keeping aviation’s safety record the envy of other transportation modes.
The FAA and our colleagues around the world know that the success of the global aviation system rests squarely on our shared commitment of safety and our common understanding of what it takes to achieve it. It’s because we have a common framework through the International Civil Aviation Organization for how we design, build and operate airliners.
Under that framework, The State of Design – which is the United States for the MAX – has the obligation to provide all States that operate an aircraft with the information that assures its safe operation. For the MAX, Boeing has not yet submitted its final request to change the MCAS, but we can share what information we do have to contribute to our safety evaluations.
So that’s what we’ll do tomorrow – explain our understanding of the risks that need to be addressed, the steps we propose to address those risks, and how we’ll propose to bring the 737 MAX back to service. And let me be very clear about that – the FAA will return the 737 MAX to service in the United States only when we determine based on facts and technical data that it is safe to do so.
We’ll also discuss how making the entire process transparent toward strengthening public confidence after two accidents. We all want travelers to have the highest confidence in the aviation system when they fly.
Once the meeting is completed tomorrow afternoon, we’ll brief you again on the events of the day.
I’ll take your questions now.
