## Summary

This document proposes the adoption of a new airworthiness directive (AD) that is applicable to all BAE Systems (Operations) Limited Model ATP airplanes. This proposal would require a one-time inspection of the fuel pipes within the fuel "float switch" test pipelines in the left and right inner wings for evidence of damage, cracks, misalignment, or fuel leakage; follow-on corrective actions, if necessary; and repetitive replacement of the fuel pipes at regular intervals. This action is necessary to prevent fuel vapors from collecting in the dry bay of the wing torsion box and consequent risk of an explosion due to fuel leakage. This action is intended to address the identified unsafe condition.
