No Bounce?

[Capair]

I'm thinking of taking out the no bounce oleo and putting standard oleo's in. What are the thoughts. I'm just not a big fan of the no bounce. I am aware of the decrease in the gross weight. What about log entries? Any input would be helpful.

If they were installed as part of a Service Letter model change you would need to remove all items required to make the change and return it to the original un-modified state.This would be a log entry.
If they were installed as a STC or major repair/alteration a 337 will be required to document the removal.
If they were put on with a log book entry that is all that would be required for their removal.

Sean,

Many people try them and do not like them, so there are not a lot of them in use. You can sell them for some $$$ but who knows how much.

The nice thing is that since you are returning it back to factory TCDS specs the paperwork should be minimal.

It was a tri champ, so it came with them. How do I handle that?

[Paul Agaliotis]

You won't be able to remove them unless you can convince the FAA that the standard oleo can operate at 1450lbs GW or reduce the GW to 1320lbs.

There must be a 337 on it somewhere when it was changed from a 'tri champ'. What does it list the GW at or rather, should I ask, was it ever changed from the tri gear weight?? 1450 as Paul suggests.

337 just says aircraft weighed. Weight and balance shows 1500 max. Reference manual shows 1450. I'm confused. I'm sure 1450 is correct.

Never say die but I think (due to the weight factor) I think you might be out of luck on installing the regular oleo struts. Maybe you can find a friendly FAA type that could help you out but I kind of doubt it. Sometimes things are better left alone rather than kick over the bee hive.

The 7FC can be operated at 1500 if it is equipt with wide track gear and is serial number 406 and above. The earlier serial numbers (7FC-347 thru 405) can be operated at 1500 if Champion Service Letters 45 and 46 are completed.
Make sure the oleo's are serviced correct. I have both type and the airplanes land the same. When the fluid gets low they land harder and wallow around during taxi.

What is a good reference for servicing the no bounce. 8.5 ounces exactly?
