In the circumstances it is my statutory duty to report those concerns to you: _ (I) Suspension issues: During the course of the Inquest heard how Ridgeback had been introduced into UK operational service as part of an urgent operational requirement to provide greater protection to UK service personnel on operation Afghanistan due to the ever increasing threat that had been developing from improvised explosive devices. heard how the original shell vehicle provided by the US manufacturer was modified to UK specifications by UK Government contractors and heard that the resultant additional weight appears to have in particular resulted in an unusually large number of failures to the front spring hanger assembly, mounting bracket as well as leaf spring failures with normal usage. Morgan Advanced Materials have been contracted to remedy the problem and understand that additional information following the involvement of and members of the team of 710 Naval Squadron will be helpful in trying to find a solution_ have been provided with a timetable in respect of which various steps will be covered leading to a solution found and rolled out which will exceed the usual 56 time period to respond to a Regulation 28 Report: As part of my Regulation 28 duty would like to monitor the resolution of the issue relative to the failures in the front suspension area and am sure that the families of the four who died on 23 June 2010, even though that the failure to that particular vehicle (Spring hanger bolt failure) did not cause or contribute to their deaths, would also like to be appraised of developments insofar as sensitive material is not disclosed. am however still concerned that the focus appears to be solely on the front suspension where the vast majority of the failures occurred. would therefore ask for confirmation that given the modifications affected the overall operational load of the vehicle that the whole suspension system is reviewed with a view that ultimately it is fit for purpose having regard to the additional operational load that UK specification vehicles are required to deal with as compared to its American counterparts_ In this respect have suggested quarterly updates as a way forward. For the avoidance of any doubt although the inquest focussed on the Ridgeback, am aware from the same Cougar family that the problem affected Wolfhound and Mastiff as well which of course the UK Government purchased as well (II) Height restrictions. During the course of hearing evidence, heard that there were height restrictions relative to the driver of Ridgeback vehicles as well as the designated Commander of the vehicle. Ordinarily both the driver and Commander sit in the two front seats of the vehicle_ The vehicle involved in this particular incident was a remote weapon system variant Ridgeback and unlike other variants, the right hand seat is occupied by the remote weapon gunner and the Commander is moved to a position sitting at right angles to the driver who of course is occupying the left hand front seat, Depending on operational assessment; am concerned that if there is a height restriction for a driver and Commander that if a gunner is required to occupy the front right hand seat; as is the case in the remote weapon system variant, that a height restriction ought to apply to the gunner as well: In this particular tragic incident found no evidence that the height of Private Alexander Isaac contributed to his inability to escape from the stricken Ridgeback once it had entered the canal as he was able to remove his helmet and body armour and in fact was one of the first bodies to_have_been recovered through the top hatch: Wiltshire & Swindon Coroner's Office, 26 Endless Street; Salisbury; Wiltshire, SP1 1DP Tel 01722 438900 Fax 01722 332223 Alex) being day

(III) Lighting At the end of the day a Commander of a vehicle has overall control and a driver is required to use his Or her skill and judgement relative to road conditions and the vehicle capabilities to drive at an appropriate speed taking into account speed limits When responding to an emergency such as in the QRF (Quick Reaction Force) role as is the case when UK civilian emergency response vehicles are responding to a legitimate emergency, speed limits may not ordinarily be adhered to and very much take the view that it should be a matter of military judgement taken by those who have situational awareness at the time The evidence heard was that operationally drivers could realistically only see using white light approximately 10-15 metres in front of the vehicle. There was an issue with the Ridgeback involved in this incident in that for some reason the main head lights had a lower specification bulb fitted 75/70 watts as opposed to the specified 100/80 watt bulb: The Ridgeback is also fitted with 70 watt lamps and set of 70 watt additional lights which were moved following the incident to the outside of the bar armour. The main lights however still lie behind the bar armour and that must impede their effectiveness would like you to review the effectiveness of Ridgeback lighting and arguably as it is part of the Cougar fleet; the lighting of the Mastiff and Wolfhound also as they are similar vehicles with the addition of an additional axle, as regards operational effectiveness especially if such vehicles are intended to be used in a QRF role or when operational requirements dictate a need to travel at speed: An operational limit of only 10-15 metres in front of the vehicle is in my view restrictive and significantly restricts the safe speed of the vehicle allowing for reaction and stoppage time. (retired) attempted as part of the LAIT investigation to carry out tests on Salisbury Plain, although do have some concerns in relation to the accuracy and usefulness of the data obtained from those tests_ (IV) Tyre pressures: The Ridgeback in question following recovery was found to have under inflated rear tyres some 13% less than the recommended PSI which believe is 110. During the course of the evidence heard that the REME maintenance crew at MOB Price did not have equipment to inflate tyres to that pressure and the on board compressor again did not have the necessary capability t0 inflate tyres over and above 100 PSI: was told that if the required tyre pressure was to be achieved that the only equipment available was at Camp Bastion and of course the vehicles were not regularly, when on operational service in Afghanistan, travelling to Camp Bastion. would ask that you review this concern: Tyre pressures are important. Both under inflated and over inflated tyres can materially affect the handling of the vehicles and if there is a specification for a certain tyre pressure then those operating or maintaining the vehicle ought to have the ability to ensure the correct tyre pressure is achievable. Again this potentially is applicable across the Cougar family fleet AESP Torque references. During the course of the evidence heard that the maintenance of _the Ridgeback vehicle was governed by AESP documentation. was told by Craftsman Ithat regularly at MOB Price during Herrick 12 whilst maintaining these vehicles that he was unaware of the correct torque settings in relation to the front spring hanger assembly bolts and would ensure in the circumstances that the bolts, to quote him, were "fucking tight" There were however torque settings but those settings appear to have been contained in the repair section of the AESP documentation in Section 5 as opposed to the maintenance section in Section 6. fully accepted the evidence heard that the AESP documentation is voluminous but am concerned and believe that it would be of assistance to REME personnel and those responsible for the maintenance of the vehicles that consideration be given to ensuring mention of a cross reference pointing in Section 6 at the relevant section to where the torque settings can be found in Section 5 rather than repeating the verbatim the torque settings again: would ask that you give consideration to this SO as to ensure correction maintenance procedures are carried out. (VI) Ridgeback emergency lighting_ was pleased to hear that the luminescent tape that was introduced following this incident is in the process of being replaced by an emergency lighting system called VELS_ believe that the additional work and installation of this system has only just started to be rolled out and would be grateful for a timetable as regards its completion and also given the similarity between Ridgeback, Wolfhound and Mastiff as to whether or not it will include the other members of the Cougar family (VII) Component failure awareness. It was clear in 2010 that failures associated with the front suspension and spring hanger assembly in the Cougar fleet were starting to develop and following an incident involving a Ridgeback vehicle_in Bovington in 2012,Qinetiq_were _instructed Tel 01722 438900 Fax 01722 332223 fog to analyse these failures_ During the course of the evidence heard from those that were maintaining these vehicles back in 2010 that the bolts on the front spring hanger assembly were in need of regular tightening and the vehicle was subject to 21 inspection checks_ The joint opinion of bothl and members of the team at 1710 Naval Squadron was that it should not be necessary 10 repeatedly have to tighten the bolts relative to a component such as the spring hanger assembly. The need for the retightening of bolts was in their view indicative of a component issue and would ask that you review from learning point as regards raising the awareness of Craftsmen Technicians and not just in relation to Ridgeback or Mastiff but in relation to any component across the services, that if an issue arises requiring regular Or unusually frequent tightening of component bolts that that matter ought to be highlighted as concern warranting proportionate investigation relative to other similar pieces of equipment experiencing the same issue, such a8 was the case here with the Cougar fleet of vehicles. The retightening of bolts on a regular basis was something that was not captured as an issue in itself:
