A Boeing flight-deck engineer who has previously raised a complaint alleging serious shortcomings in the development of the Boeing 737 Max has asserted that there are systematic problems with the design of the aircraft.


In a letter written to the Senate by a Boeing flight-deck engineer, Curtis Ewbank, he has mentioned that the systematic problem must be fixed before the 737 Max is allowed to return to service.

As reported by The Seattle Times, Curtis Ewbank is a 34 year old flight-deck systems engineer, who was involved when the Max was in early stages of development.

In the letter written by Ewbank to the US Senate and publish by The Seattle Times, he wrote:

“I have no doubt the FAA and lawmakers are under considerable pressure to allow the 737 MAX to return to service as quickly as possible and as soon as the public MCAS flaw is fixed.”

He argued that fixing only Maneuvering Characteristics Augmentation System (MCAS), which led to two fatal crashes in Indonesia and Ethiopia, killing a total of 346 people on-board is not enough.

Ewbank also suggested that similar shortcomings in the flight-control systems may affect the safety of Boeing's new 777X widebody jet, which is not yet in service.

In a recent Department of Transportation (DOT) advisory panel report on the Max crashes, he called the report as "a serious threat to aviation safety and the flying public."

He also faulted Boeing and the Federal Aviation Administration (FAA) for "allowing such reckless disregard of regulations and aviation safety."

Regarding the letter, a Boeing spokesperson said:

“We have not seen the letter."

"Accordingly, Boeing does not comment on the substance or existence of such internal complaints,” the spokesperson added.

However, earlier Boeing said that when the Max returns to service it will be one of the most thoroughly scrutinized aircraft in history.

Ewbank also said that investigators from the FBI and a U.S. House of Representatives committee had reached out to him after the Seattle Times published his internal ethics complaint last year.

Boeing 737 Max have been grounded for over a year. Over 400 newly built 737 Max are currently in storage. The Max's grounding costs has increased by $2.6 billion over the last quarter totaling just over $18 billion.

When do you think Boeing 737 Max will return back to service? Once re-certified will you fly on the Max series? Feel free to share your thoughts in the comments below:

  1. I hope Max can be back as quick as possible. I don't think it is good that some one magnifies some normal issues to prevent Max from returning back to the market.
