Boeing holds test flights for 737 MAX fix: sources
Washington: US aviation authorities will defend their certification methods for new planes before lawmakers Wednesday, two weeks after grounding the Boeing 737 MAX over two deadly crashes in less than five months.
Boeing has flown test flights of its 737 MAX to evaluate a fix for the system targeted as a potential cause of the crashes, two sources familiar with the matter said Tuesday.
The aviation giant, which has been under fire and has seen its flagship narrow-body planes grounded since March 13, tested the system upgrade on Monday, two days after pilots from American and Southwest Airlines did simulation flights in Renton, Washington, the sources said.
Boeing needs authorization from the Federal Aviation Administration (FAA) before the MAX can return to service. But the company still has not submitted its proposed software patch to the FAA, a government source told AFP.
The aircraft was grounded following two deadly accidents involving Ethiopian Airlines earlier this month and Lion Air in October that together killed 346 people.
A Senate Commerce Committee panel will hold a hearing Wednesday to question FAA Acting Administration Daniel Elwell and Transportation Department Inspector General Calvin Scovel.
The session is set to be followed by a second hearing at a later date with Boeing, airline pilots and other stakeholders.
The officials are expected to face questions from lawmakers on the FAA's certification of the 737 MAX -- and whether regulators have become too cozy with the company and fast-tracked some approvals.
Engineers have been focusing on problems with the Maneuvering Characteristics Augmentation System (MCAS), a stall prevention system designed to point the nose of the 737 MAX 8 downward if it is in danger of stalling, or losing lift.
The system has been criticized since it can malfunction and make it difficult for pilots to control the aircraft. Both of the recent crashes occurred moments after takeoff.
Boeing said it will be "carefully monitoring" the aviation officials' testimony, adding that "safety is our top priority." The FAA was "directly involved in the system safety review of the Maneuvering Characteristics Augmentation System (MCAS)," Elwell will tell lawmakers, according to prepared remarks seen by AFP.
"FAA engineers and flight test pilots were involved in the MCAS operational evaluation flight test," the remarks read.
"The certification process was detailed and thorough, but, as is the case with newly certified products, time yields more data to be applied for continued analysis and improvement."
However, Elwell is set to acknowledge that with increasingly complex systems, "our oversight approach needs to evolve to ensure that the FAA remains the global leader in achieving aviation safety." The FAA is expected to defend its practices, including the delegation of key testing and certification to Boeing in light of tight government budgets, said Scott Hamilton, an aviation expert with Leeham Company.
Lawmakers could push the FAA to pledge rigorous oversight before allowing the 737 MAX to return to service.
Elwell was set to concur, saying authorities will only allow the aircraft to fly again "when the FAA's analysis of the facts and technical data indicate that it is appropriate."
Preliminary results in the investigation into October's Lion Air crash in Indonesia indicate a single "angle of attack" sensor, which feeds data to the MCAS, malfunctioned but continued transmitting data to the plane's flight systems, including the MCAS.
Among the changes to the system, the MCAS would automatically be disabled in cases where there is disagreement between two sensors, the sources told AFP.
Boeing also intends to make standard on planes a "disagree light," to signal when the MCAS malfunctions. The feature currently is only available to airlines for an additional charge.
"Frankly, I think Congress itself should be testifying on its decades of underfunding the FAA to do its job of overseeing the aerospace industry (as well as modernizing Air Traffic Control)," said Hamilton. "But it won't take this responsibility." Scovel likely will be asked what he has learned so far in the Transportation Department's investigation into the FAA certification of the 737 MAX, which was requested by Transportation Secretary Elaine Chao.
Chao sought the audit to develop "an objective and detailed factual history" of the process of certifying the aircraft," she said in a memo to Scovel last week.
The MCAS was installed in the MAX because the engines are heavier than in the previous version of the 737.
Meanwhile on Tuesday, a Boeing 737 MAX aircraft operated by Southwest Airlines made an emergency landing after experiencing an engine problem as it was being ferried from Florida to California, the US Federal Aviation Agency said.
Southwest said the plane experienced an engine problem "shortly after takeoff." "The crew followed protocol and safely landed back at the airport" around 3:00 pm (1900 GMT), spokesman Chris Mainz said.

Telangana CM urges Amit Shah to increase sanctioned strength of IPS officers in state
Hyderabad (PTI): Telangana Chief Minister A Revanth Reddy met Union Home Minister Amit Shah in Delhi on Wednesday night and urged him to increase the sanctioned strength of IPS officers to the state in view of its growing administrative and security needs.
The two leaders also discussed the recent surrender of several senior Maoist leaders before the Telangana Police and other issues.
"During the meeting, the two leaders discussed the issue of Maoist surrenders and their rehabilitation. The chief minister informed Shah that significant improvements in policing have taken place in Telangana over the past two years," an official release here said.
Highlighting that 591 Maoists have laid down their arms and joined the mainstream of society during this period, the chief minister said the state government was providing them compensation and rehabilitation assistance as per the rules.
He requested the Union home minister to extend financial support from the central government for development works in the backward regions of the state.
Reddy also urged Shah to increase the sanctioned strength of IPS officers to the state from 83 to 105 in line with the state's growing administrative and security needs, the statement said.
The first cadre review after the formation of Telangana was conducted in 2016, while the next review, due in 2021, was delayed and finally carried out in 2025. Even then, only seven additional IPS officers were allocated to the state, the chief minister informed Shah and requested that the third cadre review be conducted in 2026 as per the schedule.
Reddy explained that Telangana, like the rest of the country, is facing several modern challenges, including cybercrime, drug trafficking, white-collar crimes, and other emerging security threats.
He highlighted the reorganisation of the Hyderabad, Cyberabad, and Malkajgiri Police Commissionerates, the proposed formation of the Future City Commissionerate and the rapidly growing population in Hyderabad to underline the increasing administrative requirements of the state.
