ATTENTION has been focussed on aspects of helicopter airworthiness by the publication of the HARP Report. In this document, existing requirements for public transport helicopters were reviewed and recommendations made for improved safety standards and it has been stated that a series of accidents in recent years, some of them related to North Sea operations, are believed to be reason for the request to the ARB which led to the setting up of the Panel. A contributory factor was the realisation that these kind of public transport operations were in their infancy and enormous expansion can be expected.
