The AAIB are positively meteoric in their response compared to some boards, e.g. Report on serious incident near Gullfaks B at Tampen HTZ 1. April 2010 with Sikorsky S-92A, LN-OQE operated by CHC Helikopter Service AS | aibn
5 years to report that: "It was discovered that the seat had detached from the rails because the forward slide stops were missing"
Given the fact that the total number of staff of the AIR part of the Norwegian AIBN is - 8 - .......I think they do well. There has not been a shortage of helo accidents and incidents the last few years unfortunately. That the Tampen case got put on the back burner is not surprising.
