§ Mr. McLoughlin
The statutory responsibility for the safety regulation of United Kingdom civil aviation rests with the Civil Aviation Authority (CAA). I am advised by the CAA that all air traffic control units within the United Kingdom have been informed that a scheme to regulate controllers' hours based on the CRATCOH report, will be implemented on 1 October 1991. A letter of intent to276W implement such regulations was despatched by the CAA in September 1990. One year has been allowed in order that ATC may bring their staff levels up to the strength recommended in the report.
