Mandatory inspections for Boeing 737 floor beams

The FAA proposes a new airworthiness directive for all Boeing Model 737-600, -700, -700C, -800, -900, and -900ER airplanes. It would require repetitive inspections for any cracks in the stub beam straps at certain stations and require repairing any crack found to address an unsafe condition. This affects operators and maintenance personnel who must perform the inspections and repairs.
