## Abstract

The FAA is superseding Airworthiness Directive (AD) 2025-07- 04, which applied to all Airbus Canada Limited Partnership Model BD- 500-1A11 airplanes. AD 2025-07-04 required a review and disposition of all existing repairs and damage assessments for affected structure, corrective actions if necessary, and the prohibition of certain repair engineering orders (REOs). Since the FAA issued AD 2025-07-04, the FAA determined that the list of acceptable generic repair engineering orders (GREOs) specified in table 1 to paragraph (h)(3) of AD 2025-07- 04 was added in error. This AD continues to require review and disposition of all existing repairs and damage assessments for affected structure, which includes GREOs that were identified in AD 2025-07-04, corrective actions if necessary, and the prohibition of certain REOs. The FAA is issuing this AD to address the unsafe condition on these products.
