Now The Boeing 737 MAX Has An Autopilot Problem

The beleaguered Boeing 737 MAX is now facing another headwind. This time, there are safety concerns regarding the autopilot. Autopilot issues are a new concern as the aircraft undergoes additional scrutiny before being allowed to return to service. The problem The European Union Aviation Safety Agency, or EASA for short, identified key details they wish to see remedied before allowing the 737 MAX to return to service. Most of these details were previously known issues with the aircraft. Here is the list, as reported by Bloomberg, of issues Boeing needs to fix with the 737 MAX: The potential difficulty pilots have in turning the jet’s manual trim wheel

The unreliability of the angle of attack sensors

Inadequate training procedures for pilots Software issue regarding a lagging microprocessor (the FAA identified this issue recently)

Failure of the autopilot to disengage in certain emergencies

Judging from the list, it seems that the 737 MAX will require a fair bit of work before returning to the sky. Whether or not the FAA agrees with the EASA is a different story. The autopilot problem The EASA discovered that the autopilot does not always disengage properly. In the case of an emergency, this could lead to an unfortunate incident if pilots do not have the time to take over from the autopilot. The FAA has been tight-lipped about all of this. Currently, the FAA faces multiple questions about their certification process that has diminished their credibility as a worldwide aviation safety regulator. Thus, the EASA is likely to wield significant influence for the rest of the world’s aviation agencies. Boeing’s statement Simple Flying reached out to Boeing. A Boeing representative provided the following statement: “We continue to engage with regulators and are providing information as we work towards the safe return to service for the MAX.”

Boeing has not revealed any details regarding this new concern from the EASA. Nor has any information been revealed as to how Boeing will fix the additional issue the EASA raised.

Timeline Boeing is maintaining their timeline of reentry to be September of 2019. Some airlines have removed the 737 MAX through October. Furthermore, some countries have banned 737 MAX flights through 2020. Ultimately, regulatory agencies will play a big role in determining when the 737 MAX will be recertified for passenger flights. Will the public fly on the 737 MAX? Civil aviation regulatory agencies and agencies definitely have this question on their mind. It is not just important for the aircraft to be recertified, but it has to be recertified with complete confidence in the aircraft. Another major source of support will be unions. If unions sign off on the aircraft and are satisfied with the changes, this can be a huge boost of confidence for both airlines and Boeing. As of now, however, the 737 MAX still has to receive certification from the regulatory agencies.
