Boeing 737s need new inspections for cracks in a key support beam
What happened
US aviation regulators are proposing new mandatory inspections for a specific part on all Boeing 737-600, -700, -800, and -900 series airplanes. This means airlines will have to repeatedly check for cracks in the stub beam straps and repair any found.
Why it matters
Airlines operating these Boeing 737 models will now have to add a new, repetitive inspection to their maintenance schedules. This change comes after reports that some support beams were not installed correctly and that current inspections are not good enough to find cracks. The goal is to prevent structural failures that could happen if these cracks go unnoticed.
The signal
Watch for the final rule to be published and then for airlines to announce how they will incorporate these new inspections into their maintenance routines.
