On Friday a Boeing 737 MAX 9 suffered a door plug blow out on an Alaska Airlines flight. The depressurized plane, carrying 171 passengers and 6 crew members, returned safely to Portland International Airport with no serious injuries.

  • Alaska Airlines grounded all of its Boeing 737 Max 9 planes on Sunday
  • US federal officials indicated further maintenance might be required to assure that another inflight blowout like the one that damaged one of its planes doesn’t happen again

Boeing will hold a company-wide webcast on safety on Tuesday to address its response.

Goldman Sachs:

  • The incident is alarming
  • a grounding of a fleet of an aircraft type leaves open questions as to what corrective actions will be required and how long they will take to perform
  • Any quality control issues introduce risk to production and delivery cadence
Reuters report on the fix that will allow MAX to return to flight after being halted in early April.
