Engineering CHIRP~A progress report
Published April 21, 1998 by Royal Aeronautical Society in United Kingdom
The original confidential reporting scheme was set up in the UK in 1982 following the creation in the US of the Aviation Safety Reporting System (ASRS). This, in turn, was instituted following the investigation into the Controlled Flight Into Terrain (CFIT) at Washington Dulles airport in 1976 of an aircraft due to a misreading of a chart; the subsequent investigation revealed that the self-same mistake had been made by another aircraft, in clear weather, some six weeks earlier and the crew were able to take corrective action. They duly reported the incident both internally and to the FAA, however, the information was not passed on to other operators. The scheme in the US is run by NASA and the UK scheme differs in some respects from that of the US. In particular, the US scheme covers Mandatory Occurrence Reporting aspects, for which we in the UK have a separate scheme.
At first, the UK scheme was available to pilots only and was managed by the RAF Institute of Aviation Medicine, which, with its professionalism and perceived independence, resulted in its wide acceptance. In 1984 the scheme was made available to Air Traffic Controllers.
A Guild of Air Pilots and Navigators review was undertaken in 1994 as it was felt that the performance of CHIRP needed reassessment against its original objectives. This led to the relaunching of CHIRP under a new management structure and the recommendations that it should be extended, in time, to other groups in the industry and should participate in initiatives related to the development of international Confidential Reporting schemes.
In July 1997 the program was extended to cover Licensed and other Engineers and Approved Maintenance organizations.
