## Key points

- The LRD on Boeing 737 Max twice filled cabins with smoke after bird strikes in 2023.
- FAA accident investigators claim the risk assessment for the LRD relied too heavily on human judgment.
- Flight simulators did not adequately train pilots on LRD activation or simulate cockpit smoke scenarios.
- A software fix will auto-close the pressure regulating valve after LRD activation, planned fleetwide by 2028.
- Both Airbus A320/A321neo and Boeing 737 Max models with LEAP engines have the LRD installed.

**Companies:** Boeing, CFM International
