Animosity2k Posted May 13, 2021 Report Share Posted May 13, 2021 So whenever I'm sitting on the ramp even with my B20 on with noise cancelling I can here a vibrating noise from the passenger side door. Yesterday I narrowed it down to the sliding window. Whenever I push it outwards (as the springs should be doing) the vibration noise stops. Has anyone else encountered this problem? Any idea for a fix? Quote Link to comment Share on other sites More sharing options...
FlyingMonkey Posted May 13, 2021 Report Share Posted May 13, 2021 Maybe pull it off the track and bend the metal tensioner tabs out a bit to provide more tension? That would be my first thing to try. I think you'll have to disassemble the window by taking a couple of screws out. Quote Link to comment Share on other sites More sharing options...

Tom Baker Posted May 14, 2021 Report Share Posted May 14, 2021 There are two different vent window installations. Mecaplex is one, and I don't remember the name of the other. I ran into this when I needed to replace one a couple years back. One uses the metal leaf, the other uses a coil spring with blocks. Quote Link to comment Share on other sites More sharing options...

I assume the attached photo is that off a leaf spring (mecaplex window). I have the blocks and little coil springs. I'll see if I can find out who makes the window.

Maybe I just need stronger coils/springs between the window and the rail. Quote Link to comment Share on other sites More sharing options...
Jim Meade Posted May 14, 2021 Report Share Posted May 14, 2021 The leaf springs are glider parts. I don't' know about the block and coil springs. Can you change to the leaf type? https://wingsandwheels.com/aircraft-parts/canopies.html Otherwise call Tom Gutman, Jr at Airtime Aviation and see if he has any used one.

Tommy Mc Posted May 15, 2021 Report Share Posted May 15, 2021 Also Dynamic balancing the Prop, if it has never been done it makes a difference. Quote Link to comment Share on other sites More sharing options...

FlyingMonkey Posted May 17, 2021 Report Share Posted May 17, 2021 I think the implication is that any issue that increases vibration/harmonics can rattle unrelated components in the airframe. Quote Link to comment Share on other sites More sharing options...

I see, and is dynamic balancing of a prop something that can typically be done the same day fly in / fly out type thing if I were to find somewhere to do it?

Yeah, takes less than an hour. I had Lockwood do mine several years ago. Made a very noticeable difference, they said mine was close to the allowable limits.

Tom Baker Posted May 17, 2021 Report Share Posted May 17, 2021 Ask the person you use for maintenance for a starter. They should know who does that locally. I would suspect that Zone offers that service. Quote Link to comment Share on other sites More sharing options...

Tommy Mc Posted May 18, 2021 Report Share Posted May 18, 2021 Sometimes you may find a local Person with the Instrument if you ask around. Most people require this service at some stage whether they know it or not. Once a mounting bracket was made it took approx 70 mins to complete the Job and the guy charged me €100.

Tom Baker Posted May 18, 2021 Report Share Posted May 18, 2021 He has a fuel injected engine, so no carb balance. Animosity, take a close up picture of the offending window and post it please. Quote Link to comment Share on other sites More sharing options...
Roger Lee Posted May 19, 2021 Report Share Posted May 19, 2021 If it's an 912iS engine it could easily be the gearbox even if the engine only had 200 hrs. depending on the year Mfg. If it's been in the last year he's probably okay with the new oiler gearbox. If it's older then it could very well be the gearbox. Quote Link to comment Share on other sites More sharing options...
Animosity2k Posted May 20, 2021 Author Report Share Posted May 20, 2021 It's a 2012 CTLSi. What would the issue with the gearbox be? So I guess the consensus is here a normal working plane should not cause enough vibration to cause the sound in the window? Quote Link to comment Share on other sites More sharing options...
Tom Baker Posted May 20, 2021 Report Share Posted May 20, 2021 If the widow is correct it shouldn't rattle, unless everything is shaking fairly bad. Post a picture of your window. Quote Link to comment Share on other sites More sharing options...
