Delta, correct me if I'm wrong, bit isn't the whole Bolkow-is-best-for-Trinity thing a bit academic? I heard that even if Bond had won the contract they were going to use the 135T2+, so the Bolkow would've been retired come Dec anyway.

Yes, absolutely, the Bolkow is about to be recycled. I only have an issue with the replacement choice. I personally, wouldn't have picked an Explorer to do that role, as it is untested in that kind of environment. I'm sure I will be proven wrong and it will be highly successful. However, I personally would rather have something with a rigid rotor head, and a more conventional yaw control system. But that's only me.
Wallsend,
You are quite correct... long live the king (105) the king is dead and we have to move on...
As a former 7 year veteran of Trinity ops, I hope the new plastic pigs measure up...
However, it's still bugging me slightly that the notar system will struggle in the more extreme conditions that the lights throw at you on occasions.
Time will tell, and good luck to the new generation........ times change and we have to change with them. ****, I used to be a Bell man through and through but now fly a multiple computer screen
As the yanks say.. go figure

BO 105's importing in to NZ
Hi
Found your post form a few years ago, we are importing a number of BO 105's into the country and one is already here. I am looking for rated instructors. Do you know of any? Regards Jonathan - Oceania Aviation Ltd.

What exactly needs to be done to a 105 LS-A3 to change it to a "Superlifter" and where would I be able to purchase the kit? (if it comes in kit form)

JB66,
Can,t help with the instructor bit, but you Kiwis standby to have fun....
The 105 is a 500 on steroids and the old hughes drivers are going to love it..
Good luck,
GTF.

For those out there that have flown the LS and CBS5, could you enlighten us on the main differences in flying them please? We're looking at a 105 in the utility role in average temps of 30deg C during summer.Mostly external loads.Will also need a rescue hoist.

The stretched version tends to be a little more unstable in pitch although this is really is only noticeable when instrument flying. For lifting, I flew both short and stretched versions and there tends to be very little difference. I can't comment on operating in higher temps as we unfortunately didn't have this problem suffice it to say that no Bolkow has a great surplus of power! We use to lift up to about 450kg but you won't have much fuel in the main tank to do this - the low fuel light in the supply tank will become well used. We had floats on ours which will of course have reduced the payload a bit.
I loved the machine even though it did try to kill me on one occasion! Make sure the hydraulic change over is spot on.

Sorry for the thread creep, but does anyone have any feedback on how the 902 is doing on Trinity house ops, or have they not started yet?
Bit out of touch these day's on UK ops......

Ahhhhh the Bo105. Loved flying it for the Police in UK in the early 90's. I flew a few of them but as usual I have no idea what the differences were apart from one being a bit longer than the other.
Do remember being on approach to an LZ one night and thought that I was moving the Nitesun in azimuth but had the wrong switch and was actually mismatching the torques giving me symptoms of an engine malfunction.
Exciting times.

Bolkow 105 Shufffle
I have recently started flying the Bolkow 105. We have CBS 4 and 5 and use it for Aeromedevac and Flying Doctor Service in the remote Interior of Sarawak. I have a few thousand hrs on maritime lynx but less than 100 on this. I recently had an 'event' (actually several) whereby the aircraft seemed to gently yaw and roll from side to side almost describing a horizontal orbit while flying forwards. Quite uncomfortable at 110 kts but I was told not to be too concerned! It seemed to happen fairly randomly but always at speeds below 60 kts. Above that it would sometimes start and then without any reason just stop. I got them to change the blades and the problem stopped. I was told by one of our Filipino engineers that it was the Bolkow shuffle, but no one could adequately explain how and why it occurs - even our Filipini pilots with a few thousand hours on type could not explain it.
Can anyone explain what has happened to the MRBs and how this is manifested as a "shuffle'. Is it something to be worried about?
I am out on a bit of a limb here and got a lot more questions depending on how I get on with this one.

I think that you might need to grease your balls.
Sorry, cheap shot at this time of the morning. The balls in question are the counterweights on the MRH. If they don't quite get to the top (or at least one of them) then this can cause a vibration.
I could be talking out of my (****) I hope that ppruner 'tbc' comes up and benefits us all with his wisdom on the Bo 105. He has several thousand on type whereas I only have about 300.
I recall one aircraft that I flew which had a massive vibration on translation to the hover with some weird control inputs to keep it S&L. I was told it was normal but when I snagged it they found that the control rigging was 'well' out.
Good luck
btw, condolences on your few thousand on the Lynx, I survived intact with 1500!

You don't get it with the Lynx because the AFCS stops it.

Balls and Dutch Roll
I thought that it may be a sticky vibration damper (balls) and I got the technicians to check them but all were ok. One engineer here said that it was the resin at the blade root breaking down allowing the blade to move within its root sleeve where it blots onto the head. Maybe?
I also thought about Dutch Roll and remember my old ground school instructor telling us about it during flying training at RAF Leeming - he was a Halifax pilot during the war. But dont recall how it happens in a Halifax let alone a helicopter. Also this particular helicopter was really bad compared to the others where it was hardly noticeable at any speed. They all tend to 'nod' a bit if you look hard but it is usually not noticeable although more so at low speed.
The porpoises along in pitch - actually a very similar effect only much less pronounced but more noticeable if you sit in the back.
Thanks you for the replies.

Daddylynx,
This sounds like a classic example. Buy that engineer a beer (or 2). The blade root "wraps" around the area of the primary blade bolt inside the titanium fittings. This area has a potting compound added for a zero gap fit. This potting can eventually break down somewhat, usually after 3500 -5000 hours. Not a big deal for the blade shop to re-do. If I recall correctly, once upon a time it could be repaired by the operator if carried out 1/4 of the area at a time.

Rigidhead

Thank you for that - we have robbed the blades of another which needs an engine change and some sheet metal work. Shuffle has gone now. We have packed up the blades and they are now on the way to Singapore to a blade repair shop called Composite Technology. Hopefully should get them back before the other one we robbed gets fixed!
So the shuffling is just a aerodynamic effect of the blades moving in the root sleeve. Would this be mainly in drag plane or flapping plane?
