Fatal R44 Crash In Nz

Recommended Posts

If you are talking about the AD on the long ranger blades. It started out as a blue dye inspection every ??? hours or an X-ray to eliminate the AD. Everyone started X-ray blades. Within a few months of them saying X-ray was fine they reissued the AD stating a serious of blades were limited to 1,400 hours then they were to be scrapped. Needless to say Bell had no blades in stock which grounded a pile of L series aircraft. The reason for this was a crash in Ontario were the blade came apart 10 ours from being at its life limit.

It was every 60 starts or less (Due to stresses on that portion of the blade during start up while rotor system spools up)

Apparently not everyone started X-raying (and it wasn't req'd by TC)

At least 2 fatal accidents occurred

The accident that occurred in Indiana: the blades had just under 800 hrs remaing (to 3600 hrs)

Bell later increased the life of unaffected blades by 400 hrs (to 4000hrs)
