SUPPLEMENTARY INFORMATION:

Background

    The final regulations that are the subject of these corrections, 
revised the bird ingestion type certification standards for aircraft 
turbine engines to better address the actual bird threat encountered in 
service, and established nearly uniform bird ingestion standards for 
aircraft turbine engines certified by the United States under FAA 
standards and by the Joint Aviation Authorities (JAA) countries under 
JAA standards, thereby simplifying airworthiness approvals for import 
and export.

Need for Correction

    As published, the final regulations contain errors that may prove 
to be misleading and need to be clarified.
