The Authority accepts this Recommendation.

Rolls Royce with the agreement of the Authority, issued a telex to all affected operators on the 7th January 2000. The telex informed operators about the incident, the area of concern and the means to commence their own inspections until a non modification service bulletin (NMSB) was issued.

Mandatory inspection has now been put in place by CAA Airworthinees Directive (AD) and Rolls Royce NMSB 78-C955 for affected RB211-524D4 engines.

The Authority has asked Rolls Royce to review other engine designs with respect to this problem.
