Chris, I like the idea of the 90Deg AN fitting, and that it keeps the line flush with the side of the fuselage. Did you run hard line ( I presume you mean ¼” 5052 Al line) all the way to the panel, of did you change to nylo-seal at some point? If so, how did you join them together? Thanks for your comment reference the static ports. I am intending to operate my aircraft IFR, and will therefore need a pair of “balanced static ports” according to my research of our Australian rules. Not sure if that applies in the USA. Rob.

Subject: [LML] Re: L360 static ports I bonded a 90 degree AN fitting into the fuselage skin. The attached hard line then sits flush against the inside of the fuselage. Also, I found that two ports were not needed so flew for the first 12 years on one. I added a second port for the autopilot. Mechanical VSIs generate some flow in the static line which the auto pilot will interpret as a small pressure difference until the VSI reaches equilibrium. A question for those who have gone before me. I am just getting to the stage of planning my static system. I plan on putting in two static ports, one on either side of the fuselage, as suggested in the manual. The recommended position is about half way along the sides of the baggage area. They suggest using a Nylon Nylo-seal 268N fitting bonded into the honeycomb of the side panel. This would protrude what looks to be about an inch into the baggage area. The Nylo-seal tubing then attaches to the fitting, which will result in the whole connection protruding at least 2” into the baggage area. Whilst I am sure this will work well as far as the static system is concerned, it seems to me that it will only be a matter of time before an errant piece of baggage being placed into the baggage area will land on the protruding tubing and damage and/or break the nylo-seal fitting. What have others done about this? I thought of using a Nylo-seal 269N elbow fitting, but it is not clear (at least to me!) from the specifications that this will work. I am interested in what others have done. Perth, Western Australia. |
