“ACCUTE SKYHOOK FALIURE” is a common occurence in pre-2009 planes, that have not been fitted with the new improved, mark 47.6 GLASS HAMMER.
These are normally activated by a low fitted lever named a “LEG PULLER”, it is quite distinguisable as it is painted with M.O.D issue TARTAN PAINT.
Or so i have always been led to believe.;)
