The Chief Inspector of Air Accidents, Mr. Jurgen Whyte, in conjunction with the appointed Investigator-in-Charge, Mr. Paul Farrell, say there were 'no mechanical anomalies' identified during the initial analysis of data retrieved from the Coastguard Helicopter that crashed off the Mayo coast last month, killing all four crew.

The statement issued yesterday says: The AAIU is keenly aware of the loss and grief of the families, friends and colleagues of the crew of R116 and extends its condolences to all concerned. The AAIU continues to work with other agencies to locate and recover the two missing crew members.

The AAIU is mindful that Sikorsky S-92A helicopters are in operation around the world in a variety of roles, including Search and Rescue. Following an event such as this, many operators and agencies are anxious to learn if any matters are identified during the ongoing investigation that may require immediate safety actions.

The Investigation is still at a preliminary stage. However, an initial analysis has been conducted of the data retrieved from the helicopter’s Health and Usage Monitoring System (HUMS) and the Multi-Purpose Flight Recorder (MPFR). No mechanical anomalies have been identified during this initial analysis.

The AAIU Investigation is ongoing and a Preliminary Report will be issued in the near future.

The Half Ton Class was created by the Offshore Racing Council for boats within the racing band not exceeding 22'-0". The ORC decided that the rule should "....permit the development of seaworthy offshore racing yachts...The Council will endeavour to protect the majority of the existing IOR fleet from rapid obsolescence caused by ....developments which produce increased performance without corresponding changes in ratings..."

When first introduced the IOR rule was perfectly adequate for rating boats in existence at that time. However yacht designers naturally examined the rule to seize upon any advantage they could find, the most noticeable of which has been a reduction in displacement and a return to fractional rigs.

After 1993, when the IOR Mk.III rule reached it termination due to lack of people building new boats, the rule was replaced by the CHS (Channel) Handicap system which in turn developed into the IRC system now used.

The IRC handicap system operates by a secret formula which tries to develop boats which are 'Cruising type' of relatively heavy boats with good internal accommodation. It tends to penalise boats with excessive stability or excessive sail area.

Competitions

The most significant events for the Half Ton Class has been the annual Half Ton Cup which was sailed under the IOR rules until 1993. More recently this has been replaced with the Half Ton Classics Cup. The venue of the event moved from continent to continent with over-representation on French or British ports. In later years the event is held biennially. Initially, it was proposed to hold events in Ireland, Britain and France by rotation. However, it was the Belgians who took the ball and ran with it. The Class is now managed from Belgium.
