Boeing device because of the problem of aircraft 737 MAX continue to be under pressure. An independent investigation of both the aerospace giants, as well as the US authority FAA look bad. The Jets continue to start.
It’s not the end of the 737-MAX debacle is in sight. After two crashes, the controversial Boeing remain the Jets probably even longer on the ground than I thought and the manufacturer remains in the criticism. How could it come to this? An independent panel has presented an analysis of. Were commissioned to the experts by the US aviation authority FAA. Result: Boeing have not stated the supervisors of the function of the control software used is sufficient.
The “Maneuvering Characteristics Augmentation System” is considered to be an important cause of the disaster in the crash of the two 737 MAX Jets from Lion Air, a year ago, and from Ethiopian Airlines in March. The Cockpit Software will actually prevent machines of the type involved dangerous flight situations and automatically take countermeasures. Probably fed up with faulty Sensor data, the MCAS maneuvered however, the two Unglücksjets apparently, in the disaster. Both machines were nearly perpendicular, and unrestrained crashed to the ground.
Possible reason: The extra for the latest and fuel-saving 737-models-written control software was revised by Boeing during the design apparently – apparently without the Knowledge of the Supervisory authority. The judgment of the examination Board: The aircraft manufacturer had not informed the FAA adequately informed of ongoing changes to the MCAS-automatic. Boeing had not concealed the supervisors of the installation of the system. However, the information flow was fragmented and separate groups within the FAA, so that they can assess, have the actual function and effect is difficult.
Criticism of licensing authority
The investigation body with the authority itself of jurisdiction in this area. So, the experts doubt about whether or not all the 737-MAX certification, responsible FAA officials had sufficient experience and expertise for the task. The authority had also not enough staff for the approval of new aircraft. The accusation still stands that the FAA should have left essential parts of the certification even Boeing itself.

The investigation Committee, the experts from America, Europe and Asia belonged to, made a total of twelve proposals for improving the FAA certification process for new aircraft types. So should inform the supervisors, among other things, a greater focus on how pilots deal with an increasing automation in the Cockpit.
“As automation becomes more complex, it is unlikely that the pilots fully understand them,” says the Chairman of the examination Board, Christopher Hart. Most of the pilots could deal with problems that occur in automated systems, said Hard, but if some don’t, it could lead to a crash. The international experts recommend that the FAA should use scientific studies to check their assumptions about pilot behavior.
Pilot associations praised the report. They had criticized Boeing, because the aircraft manufacturer had informed only after the first 737-MAX-crash about to Board the machine, the used Software was installed. FAA chief Steve Dickson thanked the Commission and announced to review the results of the independent investigation and to draw appropriate conclusions.
Removal of the Boeing-heads
Only hours after the publication of the report, Boeing announced an important personnel decision: The aircraft manufacturer, has separated the so far, from Dennis Muilenburg in a personal Union, held senior posts in the management Board and the Board of Directors. Muilenburg stay the boss of the group, to give up the chairmanship of the Board of Directors, however, said Boeing.

The task of the Chairman is to take over David Calhoun, a senior Manager of the investment company Blackstone. Due to the separation of the Offices Muilenburg was able to concentrate fully on day-to-day business. He should be able to full – time to the intended re-authorisation of the 737 MAX, as well as to the needs of the customer and the product-and Service-safety care.
If and when the 737 MAX is allowed to lift it again, is currently unclear. In the light of Boeing’s ongoing difficulties at the desired re-admission some of the affected airlines consequences. So United Airlines plans this year with the use of the problem plane. The machines are up to 6. January from the United flight plan cancelled, as the company announced. As a result, many flights are in addition-and even in the operating travel slow around Christmas and the new year. Originally United with a failure to 19 had. December expected.
On Wednesday already American Airlines flights with Boeing Krisenjets to 16 had. January is deleted. The third large U.S. airline with a 737-MAX-planes in the fleet, Southwest Airlines, omitted in your flight plan up to 5. January on the machines.
Boeing even confirmed yet, is expected in the fourth quarter of the current year with a renewed operating permit. At the beginning of the week, the Reuters news Agency reported, however, that the ultimate certification test flight, not before the 1. November can take place. Thus, it is unlikely that the re-approval of the type of aircraft, prior to December of to. Also many observers, the Boeing forecast is fairly optimistic, especially since there could be inconsistencies between the FAA and international regulatory authorities. The 737 MAX at least remained outside of the United States still on the ground.
