The incident signal was circulated around the Lynx fleet within British forces, I am afraid that I don't have one to hand but it does not really shed much more light on the matter.
Lynx at 1000' over the Lee valley waiting to enter the heli lanes and initiating a right hand turn to orbit whilst waiting for clearnace from Thames Radar. LHS was minding his own business lokoing at the maps for the next lane. When he noticed that the AOB was exceeding 40 degrees or so he looked towards the RHS as if to say 'cut that out!', or words to that effect! It was then that the RHS declared a hydraulics malfunction and LHS immediately de-selected the Hyd 1. Recovery was not an instantaneous jerk but a gradual one. Height loss was 300', AOB was in excess of 70 degrees and it had turned through 180 degrees.
Urgency declared and recovered to nearby Stapleford due to built up areas and nature of terrain.
The cyclic was continuing to ramp over to the right and the RHS insists that there was absolutely nothing that he could do about it, despite his best efforts!
The investigation was delayed for a few months as it went straight to Fairoaks for a mod. Cause was not identified although the servos were replaced with Faireys.
All good stuff. There is one thing you can guarantee with the widow maker, it will keep you on your toes!
