Julie Andrews: Yes they do, for CHC they use FDM ( Flight Data Monitoring) to meet the requirements of HOMP.

Sasless - I don't think there is a difference - I was thinking about ground taxiing a 365 (castoring nosewheel) and how it rolls out of the turn when you yaw it. The same used to happen in the Wessex/Sea King (castoring tailwheel) - one Wessex student of mine many years ago got us up on two wheels (left main and tail) being a little spirited with his first ground taxiing!

Is the 92 operated to PC1 or still the PC2DLE fudge?
How would that be relevant to the incident?

Julie, obviously you have never flown one or looked at the RFM.

I can't see either, like 212man, how PC1 or PC2DLE in this case is relevant.

Edited to take out comment "terminus mos: you clearly don't know 212man's background do you?" because I misread his post. Thanks for pointing this out 212man.

I think you'll find he does (he may even have had dinner with me in Brunei ) and I think he was referring to Julie's comments

sorry gents - should have been a bit clearer.
I'm thinking about how different profiles require different applications of power and the individual's 'individualist' approach to applying them.
I have been sat in seat where pilot thought a quickstop and 'snatch' of power at the end was a good way of approaching and thought the geartrain would not 'like' it.
thank you for clarifying PC1 profile and HFDM following.

Breaking: Sikorsky grounds all S-92 helicopters after North Sea platform incident

Written by Lee McCann and Niamh Burns - 10/01/2017 10:09 am

All North Sea helicopter flights have been grounded today over safety fears.

Sikorsky S92 helicopters have returned to base following a probe into a recent incident on a North Sea platform.

It’s understood the request to ground the S-92s was at the request of Sikorsky.

A spokesman for Aberdeen International Airport said: “We are aware of a safety alert that has been issued for all S92 helicopters and are anticipating a potential impact on helicopteroperations over the next few days until essential maintenance has been carried out. We will support the operators as much as possible through this disruption.”

The move comes after an incident involving an S-92 on a North Sea platform last month.

The helicopter flight had been making a shuttle flight between Total’s Elgin platform facilities and West Franklin, around 130 miles off the coast of Aberdeen.

Images later emerged of the damage to the platform as the flight attempted to land with nine passengers and two crew on board.

A source at the time said the S-92 took “gouges out” of the helideck, damaged its wheels and spun on the deck of the West Franklin when it was forced to land.

The decision to ground S-92s comes after Super Pumas were banned in the wake of a North Sea helicopter crash off the coast of Norway which killed 13 people on April 29th last year.

And HUMS close monitoring of the Tail Rotor Pitch Change Bearing is now required.


Sikorsky taking the lead from Airbus?

Can we assume that this grounding includes SAR S92's ?

It's not a grounding - it's a once off inspection followed by increased HUMS surveillance (more frequent downloads). Yes, SAR aircraft must comply too.

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......

..upon receiving the bulletin took the decision ...
Not much 'decision making' available in the ASB

Compliance is essential.
