Summary

The document titled 'WITHDRAWN / CANCELLED - TRANSPORT CANADA AD CF-2007-21R1 AND FAA AD 2007-19-53 HAVE BEEN ADOPTED BY EASA' is an EASA Safety Information Notice 2007-25 issued on 2007-09-17. It addresses tail rotor blade safety issues on various Bell helicopter models including the 204B, 205 series, 206 series, 206L series, 212, 222 series, 230, 407, 412 series, 427, and 430. The notice references Transport Canada Emergency AD CF-2007-2L1 and FAA Emergency AD 2007-19-53, which require inspections and corrective actions for tail rotor blades with missing balance weight screws.

What changed

This notice informs that the referenced Transport Canada and FAA Emergency Airworthiness Directives have been adopted by EASA as safety information rather than formal ADs, since the unsafe condition results from improper repairs and does not affect type design. It clarifies that EASA does not issue ADs for issues unrelated to design approval but highlights the serious safety concern. The document withdraws or cancels previous Transport Canada AD CF-2007-21R1 and FAA AD 2007-19-53 in favor of this consolidated information notice.

Why it matters

This matters because missing balance weight screws on Bell helicopter tail rotor blades can lead to in-flight detachment of weights, posing a significant safety risk. Operators, maintenance organizations, and compliance teams must be aware of the issue to prevent potential accidents. The notice ensures harmonized awareness across jurisdictions and informs EU member states that they may adopt the referenced Emergency ADs under their registry responsibilities.
