AD/SB Support for Part 121, 125, and 135 Operators

---

KRD Aviation helps operators address AD/SB gaps, implementation risk, documentation exposure, and method-of-compliance questions before they become operational, regulatory, or ownership-level problems. 

AD/SB compliance issues often require more than a records check. Operators may need to interpret requirements, evaluate exposure, determine whether documentation is sufficient, translate requirements into executable maintenance actions, and communicate the path forward to leadership.

KRD Aviation supports operators with AD/SB interpretation, implementation planning, SB incorporation, compliance strategy, maintenance execution documents, and method-of-compliance support where needed.
