## Summary

We are revising an earlier proposal for all Airbus Defense and Space S.A. Model CN-235, CN-235-100, CN-235-200, and CN-235-300 airplanes; and Model C-295 airplanes. This action revises the notice of proposed rulemaking (NPRM) by reducing a certain compliance time, adding repetitive inspections and operational checks of the affected fuel valves, and providing corrective action if necessary. We are proposing this airworthiness directive (AD) to address the unsafe condition on these products. Since these actions impose an additional burden over those proposed in the NPRM we are reopening the comment period to allow the public the chance to comment on these changes.
