Response: In view of the dynamic structural testing conducted by general electric to demonstrate the effectiveness of the changes now being implemented by airworthiness directive, we do not believe that a requirement for further bird testing would be justified.

Response: notices of proposed rule making have been issued specifying that the modification of inservice engines commence immediately with a scheduled completion date of June 1, 1977, for CF6-50 model and July 1, 1977, for the CF6-6 model engines. The modification is being incorporated in all new production engines. We believe that the action described above satisfies the intent of the recommendations.

Response: This is to keep you apprised of developments with regard to your safety recommendations a-76-59 thru 64, as requested in your letter of April 9. As a first step, a general notice (genot - an FAA internal telegraphic message) was developed and transmitted to all regions to implement a 60-day special emphasis program designed to identify airports having bird problems and to initiate action directed at alleviating the hazards at these airports. The genot included a list of available publications to assist field personnel in the formulation of local programs. A copy of this gento is enclosed. We will keep you informed of further developments.
