I had the same problem and needed to reduce the tube length about 1/4 inch on each side. As the flaps extend they travel inwards and there is a potential for them to foul and make it dificult to finish the gear up cycle. With load on the wings (slight ) extra diheadral is there so I applied an upload about mid span before I could find what was happening.

Retraction commences easily enough but resistance rapidly builds and near the end of the stroke resistance builds to a point where I end up with max effort about three mm short of the uplock shoulder. This difficulty has been growing over a period of time--but in the past overcome by pushing harder. Gear extension is easy with no problems. Is this simply a bungee problem? Have others experienced a bungee age problem where the bungee had to be replaced? If so, how does one attack the replacement procedule? Would a slightly thicker bungee be better? Looks like the job will be quite involved. Or, if the bungee should still be good, could there be some mechanical or misalignment problem?

I replaced mine at 300 hours when on the annual inspection it was impossible to get the gear up with the aeroplane jacked. On a Classic the job involved removing the exhaust and the stainless centre firewall. After that it was straight forward and took less than an hour. Using the standard Europa supplied bungee worked well for me.

So how about a DOTH?. There is a voucher for Conington ( Peterborough) in Pilot - it is pretty central and has 2 hard runways. Food should be available, tho' I've never been there, so don't know how good it is. 1200ish as usual.

We had a similar problem (our A/C has been flying about 5yrs). We raised the plane on a hoist (suspended from engine mounts) and removed wheel and removed/ cleaned rubber block and shock absorbers. We found there was considerable stiffness in the bearings on the landing frame. These were freed by lubricating with teflon spray/ light oil and the U/C cycled a couple of dozen times to work the lube in. We also replaced the rubber block. The gate through which the operating lever protrudes also needs a light greasing (eg: vaseline). This has pretty much cured the problem so there is currently no need to tighten up the bungee cord. If this does become necessary it might be easier just to add a couple of lengths of luggage cord using the hook ends to attach to the landing frame and bar on the swinging arm. This could be accessed from the underside. Replacing the original cord is almost certainly an engine removal (and firewall) job. Hope this helps resolve your problem.

Ian asked for my comments on the Zaon MRX PCAS. I wouldn't be without it, although the lack of mode C on so many aircraft in the UK is quite alarming. However, awareness of this shortcoming hopefully improves the quality of my visual scan, which further increases when the MRX starts shouting! I am saddened that none of the European aviation authorities saw fit to consider TIS uplink when mandating Mode S. Banging on how mode S was necessary for aviation safety, and then not including the one item that might save us in uncontrolled airspace (and convince us to spend the St2000) beggared belief.

I had a similar problem and resolved it by replacing the bungee with same diameter but adding 1 more wrap to the schedule. I believe the drawing shows 6 or 6-1/2 turns, just add one more complete wrap and that should fix it. Replacing the bungee is a bitch but if you use wedges between the cord and the firewall to jam the wraps on the upper cross member it will be easier. Hope this helps! kp ________________________________ Message 12 ____________________________________ Time: 02:03:18 PM PST US From: "David Joyce" Subject: Re: Europa-List: GPS antennae siting Willie, It sounds from your replies that top of instrument panel gives OK results, but I wonder whether the fuselage top between your doors may give even better results, as I can imagine that pilot and passenger will blank some satellites for a panel aerial in some situations. Everyone I have flown with on the trips I have done in Italy have lost GPS signal at some point, but I never did. I had tended to put this down to superior performance of my Garmin 295 as opposed to most people's Skymaps, but it may be because I have my aerial above head level. The cable supplied by Garmin and by Blue Mountain is plenty long enough to reach there, and otherwise gets coiled up behind the panel where it could possibly be subject to electronic interference.

Presumably, as well as avoiding the shielding effect of the crew, antenna height relative to the engine and the metalwork in the panel itself would help comms with satellites close to the horizon. On our last French trip in October, (Paddy Clarke, Alasdair Milne, myself) we all lost GPS signal at various times as well. In addition, my "Old Faithful" 295 died peacefully (so peacefully that there was only a frozen display with no explicit warning that it was meaningless - charming).

This is much more significant in northern Europe (London 51 29' N, Paris 48 49' N, for example) where the satellites are near (or below) the southern horizon most of the time. I suspect that eastbound and westbound flights will get better reception than northbound and southbound flights if the antenna is within the panel since both the crew and the engine will tend to shadow the antenna. Can anyone confirm or refute this hypothesis from in-flight experience?
