## Summary

We propose to supersede Airworthiness Directive (AD) 2011-21- 06 for all BAE SYSTEMS (Operations) Limited Model 4101 airplanes. AD 2011-21-06 currently requires revising the maintenance program. Since we issued AD 2011-21-06, we have determined that the life limit of certain main landing gear components must be reduced, and certain post- repair inspections of critical structure are necessary. This proposed AD would require a new revision of the maintenance/inspection program. We are proposing this AD to prevent failure of certain structurally significant items, including the main landing gear and nose landing gear, which could result in reduced structural integrity of the airplane; and to prevent fuel vapor ignition sources, which could result in a fuel tank explosion and consequent loss of the airplane.
