October 28, 2019, ©. Leeham News: Tomorrow it’s one year since the crash of Lion Year JT610 into the sea in Indonesia. The aircraft which went down was a brand new Boeing 737 MAX 8 and the world was stunned how such a new aircraft could crash.
The crash triggered the deepest crisis in Boeing’s 100-year history and revealed shortcomings in Boeing’s and FAA’s airworthiness work and supervision. The Lion Air JT610 final report was issued Friday and we now know what happened.
The report is giving detailed information about what happened and also investigates the chain of events that led to the crash. Based on these investigations it points to deficiencies and makes recommendations in the following areas:
Boeing issued a press release Friday where it said it has cooperated with the investigation and have done changes to the aircraft in the areas recommended in the report and that the verification of these changes have undergone “an unprecedented level of global regulatory oversight, testing and analysis”.
The tone in the press release is very different from earlier Boeing communication regarding MAX and the crashes:
“We commend Indonesia’s National Transportation Safety Committee for its extensive efforts to determine the facts of this accident, the contributing factors to its cause and recommendations aimed toward our common goal that this never happens again. We are addressing the KNKT’s safety recommendations, and taking actions to enhance the safety of the 737 MAX to prevent the flight control conditions that occurred in this accident from ever happening again.”
No comments about Pilot proficiency or Lion Air’s questionable maintenance work around the MAX problems, even though these areas are pointed out as lacking in the report.
The changed tone is coming over as more convincing and more appropriate, a Boeing focusing on the problems in their own domain. It took a long time coming though.
We will run a series of Bjorn’s Friday Corner articles where we go in detail in all the areas listed above. The report clears a number of areas where there wasn’t enough information before. It will also analyze Boeing’s change work around MCAS in more detail.
