Plt i think you are mistaken duplicate and independent several years ago I was the QAM of a now defunct small airline and whilst auditing a work pack noticed that the same engineer was indeed duplicate inspecting his own work when I pulled him up on it and I quote 'we can do this as long as we go for a coffee after the first inspection' the job was fitting a propeller.So unless things have changed in recent years the original quote was correct.
@roundwego: How many fasteners attach the BBQ plate to the transmission deck?
Also: just FYI, three of the four office chairs in my house, and most of the office chairs in the office where I work, have five rolling wheels. It appears to have become a standard among certain office furniture manufacturers.
For lowfat: link was very informative/useful.

Ref. Office chairs, I guess you are talking about the single leg with five feet ones.

Office chairs with five legs !!!! What office do you work in?
Three legs provide perfect stability. Have you never been in a restaurant at a table which rocks from side to side? Chances are it had four legs. Remove one leg and it will be rock steady.

Also, I've yet to see someone on here who uses there real name! Someone must have? Chances are a lot of us know each other already or heard the name. Plus there probably wouldn't be as much criticsim amongst eachother!! It would be interesting though

As long as a break is taken between the original and duplicate inspection then the same person can carry out both according to Norwegian regs. Unless this has changed recently then that is still the case.
3 legged chairs don't rock but the legs need to stick out much further to give stability against tipping over. 4 legs don't need to stick out as far and 5 legs can stick out less again, for the same stability. It's all about the size of the footprint and the amount of material used in the construction. After that the number of legs starts to add to the amount of material used and is less cost effective. Having more legs does not mean that each leg can be less solid as any 2 legs need to be able to support the weight at the point of tipping over. Of course, once you get more than 3 legs you need to have a flat floor to stand it on to prevent rocking.

@Beaucoup Movement: Truss elements are characterized by being fixed at both sides. Sad to say this will differ sometime in helicopters. We are debating applications of forces, bending loads, shearing forces, vibrations and redundancies (!!!) and no coasters under a table-leg.
Regardless to your graspable sense of humour, your theory is misleading in Newtonian mechanics. But not only by Newton I insist in a ’Penta-pod’; for each rotor blade one leg (suspension bar)

Norwegian and UK CAAs extend restrictions to L2
Following the tragic Norwegian Super Puma helicopter accident on Friday 29 April, the UK and Norwegian Civil Aviation Authorities have been collaborating very closely and are united in their approach.
Shortly after the accident, both organisations introduced restrictions to the Airbus EC225LP helicopter to prevent operators using it for commercial flights. Both organisations have now also agreed to extend the scope of the restriction to include the AS332L2 Super Puma helicopter until further information is available. The decision to extend the restriction is based on the close similarities between the two types of helicopter and neither helicopter can be used by either UK or Norwegian operators for commercial flights.
The restrictions do not apply to search and rescue flights.
The accident remains under investigation by the Norwegian authorities and we remain in close contact with all offshore helicopter operators to continue to assess the situation.

Strange but True: Turning a Wobbly Table Will Make It Steady - Scientific American
I have read the entire thread with great interest (fixed wing transport pilot, (ret'd), not a heli pilot), and have a basic question in re the missing pin theory - has the presence of all three (six, really) suspension rod-end pins with their two "nappy" retaining pins been confirmed yet? Are there any remnants of the barbecue plate attached to any of the three rods?
Re the loss of one of the three points of suspension and retaining control over the machine, the chair examples are, of course, in compression - if we are suspending a load from three points and one point breaks, the "system" will take up a new physical position defined by the two remaining points of suspension and the vertical loads, (plus the complex mixture of loads offered by the rotating mass as the rotor "disc" changes position), unless some vertical load-bearing capability is retained, if even for a short while, by the MRH/MRG structure, (familiarity with these components only gained by the descriptions of the structure as posted or linked on the thread).

@Fareastdriver: Do you want to tease me, do you? Or would you even tell me the five pontons of the “penta-platform Alexander L. Kielland“ had been fixed non-positive (by mechanics, e.g. by bolts & nappy pins) direct to the ocean bottom?
Please take notice: For AS332L2 Super Puma I insist as optimum in a ’quatro-pod’. Don’t wonder why? Mnemonic might be the answer.
@212man:
Congratulations to both organisations for their hard-line posture.

Sorry, I am abit confused.
Isn't Norway part of EASA ? and the maintenance carried out iaw Part145
Therefore how come you have different regulations relating to Independent Inspections !
I have heard of this practice in the USA but never in EASA Land
Can someone please explain
Sorry, I retract my above comment, I thought Norway was under EASA Regs. My apology.

Can't be a Sus Bar failure because the Gearbox split in 2 parts.
Sus Bar or Pin failure would see the Barby Plate and whole gearbox leave the scene. Almost has to be major Gear failure internal to the Gbox.
I bet my bottom dollar they are the bits they want to still find.

Keepitup, you can only understand my confusion on this especially concerning when I asked the UK CAA for guidance which was duly sent which I showed the accountable Manager who advised 'thats not how it is done here' I left shortly after that.

But how could that possibly be controlled again think difference between duplicate and independants and more concerning how the NCAA can bypass top level requirements of EASA

…. you don't know whether to cry or to curse in rage?
Berlin/Oslo (dpa) - Der Absturz eines Eurocopter-Hubschraubers an der Küste Norwegens hat nach Angaben der deutschen Luftwaffe keine Auswirkungen auf die Flugbereitschaft der Bundeswehr. «Das in Norwegen eingesetzte Modell H-225 Super Puma - auch Eurocopter EC 225 - haben wir nicht im Bestand», sagte ein Luftwaffensprecher am Samstag [30. April 2016] der Deutschen Presse-Agentur in Berlin. «Es ergeben sich daher keine Konsequenzen, irgendwelche Überprüfungen an unseren Helikoptern [Cougar AS-532-L2] durchzuführen oder gar den Flugbetrieb mit Hubschraubern der Flugbereitschaft einzustellen.»
Translation: Berlin / Oslo (dpa) - According to the German Air Force, the crash of a Eurocopter helicopter on the coast of Norway, does not affect the Special Air Mission Wing of the German Ministry of Defence (BMVg) to the Bundeswehr (German armed forces). «The Model H-225 Super Puma - Eurocopter EC 225 operated in Norway we do not have in stock,» an Air Force spokesman said on Saturday [30th of April, 2016] to the German Press Agency in Berlin. «Therefore no consequences are resulting to execute any savety inspections on our helicopters or even suspending flight operations with helicopters [Cougar AS-532-L2] of the the Special Air Mission [and VIP-] Wing of the German Ministry of Defence to the Bundeswehr»
