Briefing

What Hype is tracking

  • Southwest’s first in-service 737-8 with an Installed Physical Secondary Barrier marks the start of operational rollouts and signals how airlines may implement cockpit-protection hardware across active fleets.
  • The move comes amid the FAA’s recently announced one-year delay to the secondary-cockpit-barrier compliance deadline, affecting fleet upgrade schedules and certification planning (see the FAA's one-year delay).
  • Carriers had petitioned the FAA for further deadline relief citing supply-chain and certification constraints, a context that will shape how quickly operators choose to retrofit additional aircraft (see carriers' petition to delay).
