Boeing 737s need more frequent crack checks after earlier fixes failed
What happened
US aviation regulators are ordering more frequent inspections for cracks on certain Boeing 737 airplanes. This means airlines must check specific frame fittings and failsafe straps more often, and repair them if cracks are found.
Why it matters
Aviation regulators previously ordered inspections for cracks on these planes. But more cracks appeared, so the old fix was not enough. This new rule means airlines will have to spend more time and money inspecting and repairing these planes, which could lead to more grounded aircraft.
The signal
Watch for reports of increased maintenance costs or grounded planes from airlines operating these Boeing 737 models.
