I have the hinge/lock installed on the right door as we purchased a T2+ cancelled order from the Spanish Rescue services

Having done filming with the right door opened and locked, I can tell you that the wind sound above 60 knots is absolutely horrible; sounds like being in a loud live concert with the drums being the major player.... The only slight relief from it is to open both front sliding windows to equalize of some sort, but really not my preferred filming ship and the filming crew hate it

How they reckon you can fly up to 110 knots like that is beyond me....

FLM rev. 9
 
Having a quick look at the latest revision I noticed Cyclic Trim System Check was withdrawn from normal procedures checklist (4.4.1.3 System checks).

Any idea on the background?

Fortyodd2 27th Jun 2012 20:42

Probably a typo which gives them something to put in Rev.10 :E

handysnaks 27th Jun 2012 20:46

Or a way of avoiding the sort of stress on the main rotor head that may lead to cracks appearing......

Phoinix 27th Jun 2012 20:52

I doubt this, the revision was approved more than 3 months ago, before the cracks.

SilsoeSid 27th Jun 2012 21:04

Do you think the cyclic trim check was more stressful than the hydraulic checks?

handysnaks 28th Jun 2012 01:46

No. Just thought I'd throw it in there. Any objections?

SilsoeSid 28th Jun 2012 07:30

EC135 transmission & engine upgrade
 
Word on the streets has it; EC is working on an upgraded Transmission and Engines (1000hp each) for the EC 135 suppose to improve the hot/high performance. It’s not the EC135 i, +, or e upgrade. Like I said, I heard it thru the grapevine.
Anybody in the know what they’re up to?

Thanks,

RVDT 3rd Jul 2012 11:36

I did notice on the CS lists on the PWC e-portal reference to a PW206B3 engine but who knows?

Aucky 4th Aug 2012 08:18

Does anyone know whether the EC135 is suitable for aerial photography (as a secondary role) in the standard configuration without the sliding door & locks. Is there a reasonable sized sliding window in most? or the possibility of 'popping out' a window thats easily replaceable after the flight like in the AS355?

RVDT 4th Aug 2012 08:40

Sliding window in some. Too small I would say.

Rear door window is retained the same as the 355 and is part of Emergency
Exit.

Problem would be FM Supplement - Flight with rear sliding door window removed.

Not aware of it on 135 or 355 for that matter which is not to say it doesn't exist
as a local approval.

Brilliant Stuff 4th Aug 2012 09:55

I see Bond have the first e in country as G-HEMN for East Anglia. I wonder how that will feel..

MightyGem 4th Aug 2012 21:33

The 135s that I'm associated with have a sliding window in the rear cabin door that we use for photography.

Photography Window
 
Aucky - Have a look at photos of quite a few of the UK Police aircraft, as mentioned by MG. Many of them have a sliding window (mostly left hand, although it can be fitted either side) which opens, without speed restriction, to provide a clear area of 18" high by 10" fore/aft. (480X320mm)
I don't know the make I'm afraid and, whilst it's not big, it's as large as the window can fit. :ok:

Helitech - a couple of years ago:

EC135 - 1006-01

Aucky 6th Aug 2012 00:13

Thanks to Mighty, Zorab & Silsoe, does that swap with the window of the sliding door of any 135 with relative ease? It looks perfect as a preference over the hassle of sliding door locks, spoilers & VNE restrictions, and safer too :ok: I know the photographer would be more restricted than no door, but the stills are not the primary role. Thanks again, this is very interesting :O

SilsoeSid 6th Aug 2012 19:46

Aucky,
I guess the next step is talking to someone at Tech Tools/EC/Bond directly. As you can see from this pic, the sliding window is simply an adaptation to the standard window that fits in the hole. Much like ordering a bubble type window, an add on accessory.

RotaryWingB2 6th Aug 2012 19:47

Why not submit a RFI (request for information) to EC UK, they have fitted many of these to UK aircraft.

pm me if you would like a specific email address.

zorab64 8th Aug 2012 00:23

Aucky - to your question "does that swap with the window?", the answer is effectively "yes", although the "with ease" bit may be more of a challenge. It's effectively a one for one swap, just the skill of the engineer that dictates how long it takes them to get the rubber strip back in, as either window tend to be a bit of a b**tard to re-fit.

Just beware that if you intend to practice an emergency push out of a sliding door window, and you have the choice, use the one without the sliding insert. I heard on the (good authority) grapevine that someone tried pushing out one with the insert but, owing to the small amount of original plastic (frame) around the sliding insert, one good thump split the plastic and effectively wrote off the window! :eek: Didn't learn if the insert was able to be re-used?

ASB EC135 62A-029
 

ASB62-029 MAIN ROTOR SYSTEM – Main Rotor Hub-Shaft - Visual inspection of the upper and lower hub-shaft flange for cracks - Rev3

With Revision 3 of this Alert Service Bulletin Part 3 of the Alert Service Bulletin is no longer required.
:D

Part 3 being

(a) Accomplish the visual inspection in the area of the blade bolts i.a.w. Section 3.B. Part 3 within the next 10 fh after receipt of this Alert Service Bulletin and repeat every 10 fh.
Note: The preflight visual still remains

That removes a serious logistics headache for now at least!

RotaryWingB2 9th Aug 2012 10:05

Still a requirement for the engineer to visit every 10fh, just no removal of the nuts necessary.

It's a step in the right direction though.

Brilliant Stuff 9th Aug 2012 12:18

Rotary Wing,
my sarcasm didn't come across me thinks.

Amazing how well they work.Not.

We have made sure the arm on which the screen is bolted on to is taken out as well when the screen is u/s because you couldn't really call it safe in case of an incident......

Phoinix 14th Aug 2012 16:11

Does anybody fly their 135 with cargo net fitted in the rear?

What is the part number of the net and approx. price?

Any problems installing the net beside flir guts?

WLM 5th Oct 2012 11:01

Phoinix, I was quoted EUR3000 for that cargo net, in South East Asia... Part number is L850M4807053 from IPC EC135 :(

Stretcher for 135
 
Hi,

Can you recommend a supplier for a simple stretcher kit that would fit in the internal cabin rails? we are not a medevac operator, but a private timber operator in the South East Asian jungle.

I need to be able to do a quick change from a rear 4 seats corporate cabin interior to only keeping 2 rear seats and a stretcher whenever there is an emergency evacuation required

Rgds

Phoinix 5th Oct 2012 12:05

Thank you WLM!

Brilliant Stuff 5th Oct 2012 13:05

We use the Bucher stretcher which folds in half when stowed and uses the rails to secure itself.

http://apps.singaporeairshow.com/sto...mgs/10477.jpeg is another option as well.

Phoinix 5th Oct 2012 17:32

A question for which TM didn't have an answer. On Pratt, you get a fadec fail at very low power setting. With twistgrip in neutral you flip out the pins and rotate the twistgrip past neutral to high setting. Doest the rate of twistgrip ensure that even at very low power fadec fail, the twistgrip can still deliver max power if needed?
These fadec/twistgrip governing ranges are a bit unclear to me.

echelipilot 5th Oct 2012 20:02

Foldable stretcher
 
Hi WLM,
we also use the foldable Bucher-stretcher which works very well for as as we fly transports of injured persons only occasionally.
Sent you a PM.

Kind regards

Tom

RVDT 5th Oct 2012 23:31

Phoinix,

From what has been shown to me if you set the offending engine at ~ .7 VEMD or thereabouts you can fly the full flight envelope without the other good engine exceeding OEI limits.

The training policy at ECD these days is you can chase numbers all over the place yet the reality is you don't need to.

Apparently you do not get "FULL" power in manual. Whatever FULL means.

And you will not get it on a Bell 205 or 212 or 412 either so....................:eek:

WLM 6th Oct 2012 03:56

Thank you for the replies concerning the stretcher, I will check them all
Regards
WLM

Phoinix 9th Nov 2012 11:56

Just a feedback from a ECD test pilot... twist grips give you twice the range needed, so if FADEC is stuck in minimum position, you are able to get the whole twist for full power if needed.


And a really serious question I couldn't find a solution for on T.I.P.I.

The modification for tail mounted balancing weights. Where can we (our company) get the modification done (Other than ECD).

Is the modification really an airframe modification, or is it just "light upgrade work". - I'm not up to maintenance phraseology.

Dragstay 9th Nov 2012 17:28

Tail balance weights mod
 
Hi Phoinix,
If your company is situated in Slovenia.
You can look if some big operator in Germany (ALT, DRF...) can perform this modification for you.

I think you can call this a modification because the aft structure of the fenestrone body is modified with a mounting bracket, weights and an access panel. Also your weight and balance is affected.
Its not an afternoons job...

Some of my own experience. We have the weights also installed but the brackets tend to crack after time. We received the upgraded brackets which are from thicker material but also these have cracks reported.

Hope you can use this info.
