    Subject: Rotax 912S
    From: Richard Holder <rholder@avnet.co.uk>
    --> Europa-List message posted by: Richard Holder <rholder@avnet.co.uk> Nigel In respect of the positioning of the banjos on a factory fresh engine. I went to see another builder yesterday, Peter Field in Windlesham. He has just hung his 912S. I took the opportunity to look at his carb banjos. They both pointed forward towards the exhaust manifold. And they were sealed to discourage changing their position. I therefore repeat my suggestion that the factory should be told and discouraged from doing this ! By copy of this email I am letting Europa and the Matronics Europa List know that some 912Ss have been delivered with the banjos pointing forward and that I have had a fraught time finding the resulting top-of-the-climb misfire.

    From: "Alan Burrows" <alan@kestrel-insurance.com>
    --> Europa-List message posted by: "Alan Burrows" <alan@kestrel-insurance.com> This would perhaps make a nice change for anyone wanting to fly over the holiday period. Anyone fancy going? (Click at the bottom line if you want added to the RFFCC mailing list) Many happy Festive Season landings to you all Alan G-CBWF If you have received this as an e-mail click here for the latest version of www.rffcc.com/041229 A Real Feast to celebrate The Days Getting Longer A Feast that won't be cancelled On 29th December 2004 the first half of the first decade of the new Millennium will be almost over, the days will be getting longer - and the Real Flying and Feasting Club of Caledonia will be facilitating a real Feast to celebrate. If you are interested in receiving an invitation click here. The Feast will be at one of these locations - every one of which is friendly: The Isle of Bute; Castle Kennedy; Fife; Oban; or Dundee (only if none of the above airports is VFR). commencing at 11:30am. The actual location will be chosen on the day itself according to the weather and invitees notified by text message or e-mail. Anyone planning to arrive in a Learjet without thrust reversers may find it of benefit to review the runway characteristics at Bute prior to landing. Should you decide against landing at Bute, Glasgow is only 15 miles away and we'll pick you up from there. Dundee is our port of last resort on this occasion but it has an excellent ILS approach - and if Dundee is selected the Feast will be at the Marmalade Pot public house. If you are a pilot we want you to come - see www.rffcc.com/basics for the details. Remember - RFFCC's Feasts are NEVER cancelled. Normally RFFCC's Feasts are entirely BYO but on this occasion, in recognition of the extreme cold and of the weather conditions generally, we will provide hot non-alcoholic toddies and pieces of haggis. But it is still BYO - all we are providing is a sip and a snack. If you are flying from outside Scotland, the classiest way to do it is to fly to either Dundee or Strathallan on the 28th and stay at Gleneagles Hotel (phone +44 1764 66 2231) the night before the feast. Gleneagles really excels itself in the festive season, and as at noon GMT on 9th December there were still rooms available for the 28th and the 29th December 2004 (mind you, Gleneagles is not cheap!). Gleneagles is only 5 miles from Strathallan and they'll pick you up there - and the Real Flying and Feasting Club of Caledonia can arrange permission for you to land at Strathallan at your own risk. Or you can land at Dundee and take a taxi to Gleneagles. Or, if you are in a helicopter, Gleneagles has a helipad. Read about our Feast on Sollas Beach Airfield in September 2004 at www.rffcc.com/04sollas Order of the day - 29th December 2004 10:30am The RFFCC barbecue is lit - fuelled by the finest Australian Red Gum 11:30am Celebrations commence with the heating of the Strathallan Haggis 12:00noon Presentation of Exceptional Flying Feat Certificates to those who landed on Sollas beach in September 12:15pm Serving of the Strathallan Haggis 12:30pm Telling of tall tales of aviation derring-do 13:00pm The homeward journey or revelry or a nap (at individual discretion) 18:00pm The evening Feast commences Please inform others about this classy event Please inform other people by printing this out and putting it on the notice-board, or forwarding it to other pilots you know. According to the event calendars on pilotweb.co.uk and flyer.co.uk and ukga.com there is not one other Real Flying event anywhere in Britain between Christmas and New Year - let alone a Real Flying and Feasting event. ---------- Rolling out onto final, runway 25 at Fife, 2nd December 2004 Mount Stuart House, Bute, 4th December 2004 If you you wish to update or view your details in our email list please click here If you wish to unsubscribe from this email list please click here If would like to receive this email in text format and not HTML please click here If this e-mail has been forwarded to you, and you wish to be added to the list in your own name, click here

    Subject: Fuel Tank access hole.
    --> Europa-List message posted by: "R.C.Harrison" <ptag.dev@tiscali.co.uk> Hi! All After my fuel line blockage and discovery of the obstructed tank outlet connectors I have decide to put a top of tank access hole for inspection and clean out purposes and maybe at a later date the use of a fuel gauge sender. I=92m given to understand that there is a requirement for about =BD metre of 10mm wide x 3mm thick PTFE Foam Sealer Strip. RS catalogue has this stuff at =A355.18 plus VAT in 8 metre rolls. Which is making my eyes water ! Does anyone have some left over from such a job or is there anyone wishing to share in the purchase of a roll? Regards Bob Harrison G-PTAG Europa 337 MKI/Jabiru 3300

This is NOT right. My misfire was at the top of the climb AFTER levelling off and reducing power, while the exhaust was still very hot from the climb. I agree that in the climb the fuel flow could be 10 inches per second, but in the cruise it is a lot less. And with the s/s braiding heat would have been conducted underneath the insulation once a hole had been melted in the insulation. I have had no problems whatsoever at this stage of flight since I changed the fuel system. The hose now goes OVER the carb to a dash-pot that simulates the dashpot that is supplied on a certified engine. New straight unions have been fitted in place of the banjos. And the s/s braided pipe replaced by rubber pipe. The problem didn't happen every time, and was minimal last winter, but it often happened when banking left at the end of crosswind. The right hand fuel hose had the melted insulation and of course that side of the engine is likely to be warmer as the air flow is restricted by the oil dry sump tank and its piping. > Perhaps the cause was something else which you > inadvertently cured when working on the engine. I am not convinced as the problem IMMEDIATELY went away when I angled the banjos backwards, and has not re-occurred since the whole fuel system forwards from the fuel pump to the carb was re-made. > Carbs and fuel lines that get hot after engine shutdown are more likely to > give vapour lock problems making hot restart difficult, or causing engine > failure after takeoff (after hot restart if fuel bleedback is not > incorporated). I have the fuel bleedback, and have never had a hot start problem. > Perhaps you could pass my comments onto the Europa list. Sure. As an aside I notice that the standard installation is oil sump scavenge pump to dry sump tank, and then from dry sump tank via the oil radiator to the main pump and the bearings. This has left the dry sump tank containing very hot (pre radiator) oil. What was the logic for that rather than what I would have done on a rally car which would have been to put the radiator in the line between the scavenge pump and the dry sump tank, which would have given cooler oil in the tank. Richard PS I agree your figure of 10 inches/sec for 27 litres/hour through a 1/4 inch ID hose but that would be in the hose from the fuel pump. The fuel flow in the pipe to the carb would be half that (5 inches per sec) and at my cruise of 16 litres an hour around 3 inches per sec.

    --> Europa-List message posted by: Richard Holder <rholder@avnet.co.uk> Team I have just bought this kit - it was described as the Mark III version. Would anyone who bought this kit last year, or before, let me know : Whether there was a temperature probe and gauge included ? Whether there was a shut-off valve included ? If the price was any different to GBP 195. I ask because others on the list have mentioned both these items and neither came with my kit, yet I believe it is still advertised at GBP 195 currently on sale at GBP 175.

    Subject: Re: Exhaust troubles 912S on XS
    --> Europa-List message posted by: Terry Seaver <terrys@cisco.com> Hi Sven, We have an XS 912S with over 400 hours on it. This has been a problem for us on a number of occasions. If you watch the muffler during a startup, you will see that the engine rotates significantly on the motor mounts, with the muffler unable to completely follow that motion. The muffler separates from the header pipes at the muffler's ball joints, with the muffler springs taking up the slack, and then slamming the muffler back onto the header pipes. If all header pipes are not very, very tight at the head attachment, one or more header pipes will be pulled out of alignment by the spring pressure, rotating the header pipe at the engine head ball attachment. Then when the springs try to pull the muffler back into position, the header pipes no longer fit properly, and one or more muffler balls do not go back into their sockets. This problem is worse on hard starts, and can be made worse if the springs lose their tension, as a result of the engine compartment temps getting way too high. It was also made much worse when I mistakenly applied anti-seize compound to the header pipe ball joints at the head attach points. The only cure we know of is to loosen the header pipes at the heads and carefully realign the muffler/header ball joints, then tighten the header pipes (at the heads) very tightly. regards, Terry Seaver A135 / N135TD Sven den Boer wrote: > --> Europa-List message posted by: "Sven den Boer" <svendenboer@quicknet.nl> > > After starting the engine and a test run, the rh back exhaust pipe had left the muffler and was =B4=B4standing=B4 on the edge of the muffler. > This despite installation according to Service Bulletin, with all springs still attached. > Any comments and help welcome. > > Cheers > > Sven den Boer > PH-SBR > A168 > > > > >

    --> Europa-List message posted by: "Cliff Shaw" <flyinggpa@comcast.net> Sven I agree with Terry. Several time the same exact problem has occurred on my 914S. I now check the header pipe alignment often, by bushing down on the muffler and see if it pops up smoothly. I think that a misalignment will cause backfiring in flight. I have had this happen to me too. Cliff Shaw 1041 Euclid ave.

    Subject: Seat belts challenge......
    --> Europa-List message posted by: "R.C.Harrison" <ptag.dev@tiscali.co.uk> Hi! All. I'm under the impression that the improvement proposals to reduce/prevent spinal compression needs the shoulder contact with the belts eliminating by arranging for the belts to pass over the shoulders from a higher point? If this is the case I'm wondering if my installation of actual BMW head rests would serve as a likely aid to the cause by routing the belts through a guide over the top of the BMW head rest. If anyone who has seen my head rest set up would care to make a pronouncement as to the potential of the idea? ..I will put some pictures on the Matronics picture page when my digital /computer clever Son gets home tonight .
