R66 4000hr Overhaul

[CRAN]

Chaps,

Have any operators got to the second overhaul on an R66 yet (on hours obvious not calendar time). If so is it significantly more expensive than the first overhaul?

Many thanks,
CRAN

No-one knows. Not many Robbies make it to that time hahaha

PPrune Rotorheads is the equivalent of a car forum where no one can ask a question about Fords – where any mention of the Ford name is met with “They’re sh*t”, I wouldn’t drive anything other than a Rolls Royce or Bentley”.

It’s a web forum, if you dislike Robinson helicopters then start you own thread on the that topic.

Most find these incessant and childish interjections on Robinsons in nearly every thread quite tiresome. If it your half-assed attempt at humour; you’re no comedian.

Lighten up Francis.
I fly them occasionally.

[Sir Korsky]

No, he's right. They are ****.

[Bell_ringer]

Comparing a Ford to a Robbie, outrageous.
Ford's stay in one piece and rarely catch fire :E

It seems today's task of the Computer Skills Class at the Learning Disability Centre was to hand out PPrune logins and let everyone talk with helicopter pilots.

You are all doing splendid. I applaud and support you; you can lead an independent and productive life.

Oh dear, someone's sense of humour seems to be on holiday........

Fords catch fire a lot in South Africa

Perhaps his sense of humour has gone up in smoke ?

[Hughesy]

Or fallen apart?

Be interesting comparing apples with apples....re 44"s and "others".

cost to buy
cost to run
cost to reset to zero
numbers sold
numbers of incidences...( private and commercial )

could go on here......let's see

I'm not going to take a cheap shot at helicopter pilots...really I'm not.

Ok let's see......Robinson... RMK.......mmmmm

Rotor Mast Katastrophy?

Joking aside, surely it will be a long time before any R66 hits 4,000 hrs?

They've only been in service for a relatively short period and I doubt if many, if any, have even hit 2,000 hrs.

[HeliHenri]

More than 800 produced.
Around 150 are operating for 6 or 7 years.
Quite a lot must have more than 4000 hours.


Sorry CRAN, I don't have the answer.

[Spunk]

Not an answer but a rough guess:
Chapter 4 of the Robinson MM only states TBOs and SLLs of 2000 hours (or 12 years in some cases). Furthermore there is only one overhaul kit offered by the factory as all life limited parts time out at 2000 hours, unlike the R44 where the tailcone, some antenna mounts and the horizontal stabilizer have to be replaced in addition at 4400 hours.
Couldn't find anything about the SLLs of the RR300 but TBO should be the same as the airframe (2000 hours/3000 cycles).

[CRAN]

Guys,

To those that have replied usefully, many thanks.

The R66 airframe is a 2000hr unit so that part of of the overhaul will be the same. However the engine requires some additional parts to be replaced at 4000hrs, so the engine part of the cost, listed as $167K will be more expensive the second time round...but how much.

Just wondered if anyone knows?

Thanks again,
CRAN

At least one in NZ that has had its 2k rebuild and is well on its way to its second.

[SuperF]

I know of at least one in NZ that is logging 100hrs / month and has been doing it for well over 2 years... must be getting close to 4000hrs by now.

[ec155mech]

SuperF : last I checked 2 year = 24 months


lets average it to 100 hours a month to account for maintenance and bad weather ect.


24x100 = 2400FH


4000-2400 = 1600FH / 100FH/PCM gives them another 16 months :D

[Bell_ringer]

Even the older machines would need to sustain 571 hours pa to reach 4000 hours in 7 years - not taking the downtime into account for maintenance and 2000 hour rebuild.
If the local register is anything to go by, the 66 seems to be used for lighter (often business or recreational) use.
There can't be many that have hit 4000 hours, given the relative youth of the type.

[Chris P Bacon]

There have been around 10 airframes reaching the 2000 hour overhaul (3 in Russia plus one crashing at 1995 hours, 2 in Nigeria and the remainder around the world).
The average engine 2000 hour PMI is $95,000 which includes the stage 1 and 2 wheel replacement. For the 4000 hour, you will need to factor in the stage 3 and 4 wheel replacement at $31,000 plus some additional wear and tear, the engine should be around $145,000 for the 4000 hour PMI.

Ok genius, "well over two years" lets say close to three years.

3 X 12 X 100 = 3600, so yeah must be getting close to 4000... at that rate 4 months to go, or maybe I'm not 100% on the dates, and they have done four years which would then be well over 4000!!! :D

Thanks Chris,

Just what I wanted to know.
