  1. Was the tail rotor recently installed? If so try loosing and retightening the attachment bolt. It can load the hinge bearings up. If tail rotor was not recently installed check the laminated bearings. I have had both cause a big shutter through the airframe around 270-320rpm. It would be smooth at idle and at 100%. I think if you had messed up teeth in the MGB, I would hope you would have had a chip light
  2. Heard canadore maybe putting one on in may if there is enough interest.
  3. I don't think it is the power cables. We had tried connecting the unit straight to the ships batt with different wires and the problem was still there. The filter/shields helped, but I can not explain or understand why they did. If you have a latitude unit they can check your box/data from there computers and possibly see if something that s up. Our trackers don't have any interfaces or connect to any systems, just power and ground to the unit.
  4. We had a similar problem with a latitude tracker. Really messed the FM up when using a repeater. FM antenna was on the boom and tracker antenna on the roof. We had an avionics teck troubleshoot with not a lot of luck. When we disabled the tracker the FM worked properly. Latitude send us some filters I think they are called, those round magnets that wire goes through. We put them around the power wires, and it helped a lot. Didn't totally solve the problem, but make a big difference.
  5. I think the 412 is a great aircraft for what the coast guard needs. I would think the 412 is better suited then the 139 for the coast guard, because they do land in unprepared sites, and I would think skids are better for that. I am pretty sure the Canadian coast guard does not winch people so I am not sure they will even have a hoist on the aircraft. From a tax payer stand point it is Canadian made and supported, plus they should have most of the required tooling, ground handling support, and some spares from the 212.
  6. Just read helieagles post again and realized that he does not have dual electrical boost pumps, so this info will not help out very much.
  7. Have you checked the boost pump pressures are correct. If I remember right the l/h book pump is suppose to be higher then the r/h when you have dual electric boost pump. Also I have heard that if a check valve in the fuel manifold at the top of the hellhole is not working corrently that your boost pump can fill your r/h tank (where fuel quantity probe is) higher then your l/h tank ( where the low fuel switch is). I have never seen this but some thing I have heard. Open up both fuel cells and take a look while the boost pumps are on. That is correct that when you have the helitrades dual boost pump the low fuel switch is 1/4 or 1/2 inch taller then stock. If the flapper valve is assembled corrently, cross feeds are not blocked, jet pumps are clean and low fuel switch is working correctly not much else you can do. I think that this is the norm, not a bad thing to have the fuel light to come on early anways. what is 10 min fuel anyway 100-150lbs. Add a 150 lbs and see where the fuel level is in relation to the switch. probably see it have half way up the standpipe anyways. Have fun playing in the fuel. SW
  8. The flame outs are not caused by the control box. The control box detects an Np over speed of 108.8 which it then bleed off PY air which then causes engine to decel. There is a small orifice in the fuel pump, that if it is a certain size (which could still be limits), it can cause the engine to flame out when you do your EOS test. I have heard that the fuel pump manufacture is working on a modification to the fuel pump to stop that. Apprently they are being tested, not sure when they are going to be available. I believe that this is why soloy calls for the EOS to be done at the last flight of the day, as you are shutting down anyways. If you where to have an actual overspeed failure the EOS deceled the engine with out a flame out, as soon as your NG gets below 100%( i think that is the number)the engine would just overspeed agian and again. So you would throttle back to idle anyways in the event of an overspeed. This is on a 700D2 engine, a 600 A-3A uses a mechanical overspeed. Hope that helps. If you have any questions call Bob Southward at intermountain turbine. Guys a LTS 101 genius
  9. Jim do you know this as a fact? As an employee, we have not been told that we have been bought.
  10. I talked to one of the pilot about the alpine seat, and he didn't like it. He didn't like how the tilt worked. You can use your left elbow to tilt out the window, but when it came time to come back in the elbow button is below the window in the door. So he had to use his right hand and reach across to push the button to tilt back in. Also if you are a pilot that like his seat pushed all the way to the back you will have a hard time. The seat can only go so far back and still be able to tilt, as it will tilt into the door post. I don't think that will affect to many pilots. I saw an alpine machine this summer with the lumbar support cut back, don't think it completely solved the problem but made it a little better. The transwest seat, the pilots have loved it.
  11. If you are going to be working on Helicopters I didn't think you needed a M2?? I thought the M1 covered you on all helicopters even if they were in the M2 catagory? but I could be wrong.
  12. I am in Mexico at the moment, I have not heard anything down here. I didn't even hear that they had a machine down here.
  13. Can you they do that if it is privately registered? I guess they can if they are doing it for free.
  14. I saw an EC135 at the Kelowna airport this morning. C-FJRX. I didn't realize that there was more then the one VIH has, in canada. Any body know where it is based out of? I think that it is privately registered to shaw communications, a nice ride for the big wigs to fly around in. SW
  15. No, I don't beleive the doors are closed. They have laid off pretty much everybody, except the people required to run the flight school. I think that they are deffinatly hurting though, probably trying to down size like many other operators, and waiting for the flying season to get started again.
