While we're on the subject, It's worth mentioning the RAF had similar issues with the Puma prior to it's introduction. The issue surfaced in the media about twenty years ago but to my knowledge, no modifications were carried out as a result of the adverse publicity.
It lacked crashworthy seats, had only one fire bottle between two engines and similar issues to the "Herk" with its fuel tanks. It also lacked anticipators on the engines, causing a situation where the engines would not give sufficient repsonse just when it was most needed. The latter issue was a likely contributing factor in an accident a couple of years ago in Iraq, resulting in a fatal accident.
