Cabin Door Lift Assist

[basloane]

This thread went sort of silent around the end of 2007. Does anybody have any updated information?

I also have been experiencing problems with my lift mechanism. The Seals and O-rings are standard items, totalling less than about $5.00, but I still cannot seem to get it to stay charged. Can't muster the nerve to spend 23,000 for a new assembly ( not going to comment on the Cessna Pricing Policy ).

I have been investigating suppliers of the Gas Springs that Mr. badboy82 speaks of in his first post. I believe I may have found a supplier in Germany with the quality worthy of use in aircraft. The website is www.stabilus.com.

Has anybody had experience with this company, or is there another company out there somewhere.

I would need to so some measureements on stroke travel, forces, etc. Are there any engineering guidelines out there with respect to additional safety margins to be applied to the lifting force required to lift the door?

Any information would be appreciated.
