The Boeing Company Proposes New Airworthiness Directive for 737-100 to 737-500 Series Airplanes

Summary

The Boeing Company is proposing a new airworthiness directive to address cracking in the webs of the stub beams at certain fuselage stations on its 737-100 to 737-500 series airplanes, which is a result of fatigue caused by cyclical loading from pressurization, wing loads, and landing loads.
