Well I'd say it is a grounding - a short term one until some maintenance action is carried out. The aircraft is grounded in the interim.

I guess it depends on what sort of a spin you want to put on it. If it was a 225 in the frame, everyone would be clamouring "Grounding"!

Not sure it needs 'spin' - it's an ASB, so requires actions within a specified timeframe, like all ASBs......

Are these flights on hold, S92s, or is it weather?

Not much 'decision making' available in the ASB

BBC news today Sikorsky grounds S92 helicopters for safety checks after incident as a "precautionary measure".

I would say there is a decision process to be made. It is a given that on oil and gas these aircraft will be grounded. However a number of aircraft are engaged SAR and as bulletins are not mandatory even if given Alert staus I suspect that in a real emergency they will launch. At time of writing I cannot find an Emergency AD from either the FAA or EASA which would be mandatory.

Depends on the maintenance statement and the AMM.

Well, considering the microscope helicopters operate under nowadays and sensationalistic headlines in some media outlets, perhaps it was a wise idea to immediately cease 92 ops until the check had been completed.
Were any aircraft turned around and RTB while enroute offshore or did they complete their trips?

I suppose some would argue the 225 is not grounded currently....despite reality.

A very simplistic question from someone who has many pax hours in helicopters. Is it fair to say that mechanical failures are happening more on helicopters? If so, is this because of modern design - i.e. Lighter components to save weight/increase payload, etc, etc.

All my hours in Sea Kings, Pumas, I never remember a Main gearbox, bearing, or tail issues, ever - certainly not 'accident' or grounding issues.

JOKE. Well..for one thing...everytime we had a chip light..or a gen failure or any other minor issue it did not get immediately reported in the media as "Helicopter Emergency Landing barely misses local Orphanage, Hospital and house with cute puppy inside! 100s traumatized!" Film at 1100. END JOKE

Nowadays any issue gets reported in the media and, unfortunately "Perception is reality".

C52304, I think its fair to say that we are now entering a time when helicopters are going straight into civil use. Both the types you mentioned had many hours (and problems) with the military.When problems were found and corrected.

c53204, if you have never seen a problem with those older types then you have been a whole lot luckier than some of us.

Can I sit beside you next time?

I seem to remember two S61 gearboxes burning out. One on the North Sea and the other an SAR machine. Engine run down and settling onto the back of a supply boat. A calm sea state was regarded as a good 61 ditching day.

The S76 threw a blade at Aberdeen and we flew next day with tie wraps holding the blade bearings in. When the turbines started bursting a ring of armour plate was placed around them to stop them damaging the luggage.

The old Puma 330 had problems with pitch horn bearings, inclined shaft hinges and a fatal at Aberdeen where an engine run down when the other was pulled back for training.

For the inaugural flight of the 234 they placed tea and biccies for the passengers, there being a cabin attendant. At the appointed time the locker was opened and there was a sea of writhing crumbs. Again a calm sea was 234 water taxiing time to get to the Shetland basin. A 234 was also responsible for the greatest loss of life.

The 332 started going through gearboxes like a lottery winner. There must have been three in the air at the same time in the hanger. Rotor heads cracking offshore, innumerable spurious fire warnings and again an inclined shaft hinge pin coming out. It took about two years to solve all the problems.

Alan Bristow, an ex test pilot, used to create at the helicopters companies because he did not know why the users had to do all the advanced test flying for them; this covered all companies.

It happened so often in those days that it didn't make the papers.

C53204,

The types you have mentioned were no doubt during military time. As a passenger you are very much kept out of the loop of problems going on. You would never subsequently be informed not was there any intention to. It's a different game in the civilian world when someone's paying for the flying.

Morale of the story being you got away with a lot more in the military.
