The Australian Transport Safety Bureau (formerly the Bureau of Air Safety Investigation) recommends that the United Kingdom Civil Aviation Authority notify all operators under their jurisdiction using Rolls Royce RB211-524D4 or similar engines, of the possibility of failure of the cold stream nozzle during operation.

Initial response
Date issued: 03 March 2000
Response from: Civil Aviation Authority (UK)
Action status: Closed - Accepted
Response text:

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.
