Just checked on Europa's website and discovered yet  another mandatory mod.

 This is Mod No. 72 and involves nearly all aircraft  and involves a check of the landing frame for cracks before next flight and  then fitting sleeves to the frame before next permit renewal or 25 hours. This  operation needs the engine to be removed.

Given that this has been made mandatory for UK aircraft by the PFA, has anyone had any notice of this from the PFA?

You've just ruined my and many Europa pilots new  year!

 Looks straight forward though, thanks for drawing  our attention to it Geoff,

Hi! Mike   

Removing and replacing your engine is straight forward ?  

 I’d describe it as something different ! I guess if you say anything quickly it can be considered “straight forward”!  

But I put tubes in on my initial build probably not quite to the control standard specified now though .  

Perhaps our Mod Committee may like to pass comment?

If its a mandatory mod, why havent Europa written  to us and why havent we been sent the requisite parts. BTW are we talking about  monos or trigears or both???

  

 We had enough of this aggro when we were building  the aircraft - about 60 or so mods from memory (yes, we were one of the early  ones (no49!!!).

  

 Now not so happy G-LABS.

All Europas except those with the classic  engine installation 

(radiators each side of the spinner) with the  Rotax 912 or 912S 

engine and Warp Drive ground adjustable  propeller or other 

propeller weighing less than 25lb (912S  engine) or 28lb (912 

engine) and no cracks found in the landing  gear frame, or those 

with landing gear frames supplied by Europa  after January 2007.

  

  

 Straight from the Mod leaflet.

I think we will all be notified in due course both  by the PFA and Europa. Parts have to be purchased from Europa either a repair  kit if no cracks found or a new complete frame if original is cracked. This mod  affects all europas except some classic installations with lightweight props  fitted. I suggest everyone reads the mod on Europa Aircraft website

Hi All,

 I have the classic engine installation with the  Rotax 912S.

 Interesting specs, as my Airmaster Prop weighs in  at 26lbs!!! except I kept the glass spinner which weighs 1 lb less than the  metal one!

 So that is within the specs as the cracks are  not there!! Already checked it long ago when the fault was first observed  .

 Will do it anyway, in time.

 My 1 lbs worth.

 Cheers,

 Tim

Hi Tim  

   

The way I read the mod the 28 lb limit applied to the 912 and the limit for the 912s was 24lbs.  

   

I am just trying to find the weight of the NSI CAP140 – it is not mentioned in the manual or any of the paperwork that came with the prop.  We may end up having to weigh it.  

   

Regards  

   

Pete

Surprising that there is no recommendation to turn  over the mount rubbers, swap top for bottom or replace.

 The weight of the engine would be borne principally  by the lower two of the four mount points; the upper arms would (because they  yield more under load) take the "nodding" loads of the engine, plus a lesser  contribution of the engine weight.

  

 As the more heavily loaded (bottom) rubber mounts  yield/creep over time, progressively more weight would be borne by the top  arms.

  

 In any case, if the spinner line has sunk below the  cowl line (as is normal with time), this would be usefully reset.

I've received no notice and will continue to  consider the mod as non mandatory until notified by the design authority, i.e.  the PFA.

  

 The PFA's website  (TADS) also does not currently list this mod.

Good thinking, but should we not as a matter of good practice be replacing

all rubber parts every 5 yrs? If so this would be a smart time to replace

the engine mounts. Regards, David Joyce, G-XSDJ

My sentiments entirely. I always assumed that the original designers knew 

what they were doing, but we are being informed at regular intervals about 

one failure after another of major components.

What exactly is the point of having the PFA. They passed the Europa with 

flying colours, and yet, some of the parts were obviously underdesigned. I 

always thought that the engine frame looked kind of flimsy, and I guess the 

nosegear frame will be next to bite the dust.

Has anyone got more details about the aircraft where this failure occurred ? 

  Was it a trigear, and what suspension did it have ?



Karl

Hi All

When the Europa was designed it was done by people like us, with a lot 

of enthusiasm, quite a bit of experience ( think Don Dykins!) but it was 

still a very steep learning curve. The early builders were sometimes 

ahead of the company, at least one of them wrote parts of the manual.

Just remember very few airplanes can do what a Europa does well and 

there aren't as many ADs as there are on a Boeing.

Some of these ADs, possibly Mod 72, I don't know yet, are written to 

save the butts of the PFA first, Europa second, but the main reason is 

to line the butts of the lawyers with even more fat at our expense. So 

imho, blame the US legal system which will eventually kill most 

everything it touches. Our UK lawyers are a few miles behind but 

catching up.

Here in Europe nobody in a position of responsibility won't make a 

decision in case someone sues them.

We might be watching the end of western civilization. Race against time, 

will the planet kick us off before we wreck it?

Apologies for being cinical but that is the effect govmint has on me.

Graham

I have to assume that it is if the same type of failure which occurred

about 1 year ago (!), and was actually posted to this list (email

below). Nobody appeared to take notice at the time.  I followed up with

an email to Sam requesting a Pic, which I have attached.

I always considered that stress-point at the bracket a weak point, and

am glad that they are addressing it (if it is the same defect!).

During preflight today I noticed that the spinner was a little offset

hanging a bit low,after removing the cowl I found that the l.g. frame

had cracked 

& separated just behind the port upper motor mount. I believe the crack 

occured when the manifold cross-over tube was disconnected during  carb

several months ago and the 914 ran so rough (with the cross-over

that it was shut down for fear of breaking a motor mount. If anyone

The pic shows the tube failed just behind the weld.

I will insert another 4130 tube/rod inside obout 4" long & tig weld the

separated member and the new reinforcment will be welded at the open end

of repaired tube. I will also do this to the starboard side.

Ron and Peter,



This looks like another incident, caused by excessive vibration, as the mod 

seems to exclude 914 installations. I wonder why the propeller weight is so 

important. My original standard Warp Drive weighed a lot less than 25 

pounds, and even my new cs Woodcomp weighs less than 25 pounds.

Vibration is always a potential problem; I experienced it a few times when 

cold starting with the old starter motor., and the frame and bolts should be 

strong enough to take that kind of punishment.

I am sure E04 will give us an update next week.

                 Wow ! You guys keep hitting

                   my fear buttons lately ....



clogged fuel filters and

                   broken engine mounts. Whenever I

                   was about to fall

asleep during my ocean crossings in

                   N81EU the visualisation of a cracked

welding in the mount and both fuel filters closed

                   shut kept a poor soul

awake. For the fuel filters I had

                   prepared though ... 2 more new filters and

several screens

                   for in-cockpit replacement.



1 Filter has actually

                   clogged up once, but the second took over.



Worst was

                   the failure of the entire fuel lines provided with the 

kit.

                   They

were simply leaking with the rubber part dissolving

                   during a flight.

Fortunately it was over land and ALL fuel

                   lines were replcaed within 2 hrs

and have kept up since.

W H A T E L S E C A N G O W R O N G ? ? Anybody needs

                   my wife's

eMail adress ?



happy landings,

Which underlines a point that the description given in the E04 text for Mod 

72 is off the mark. It tries to be clear about the effected area but, if 

this is it, fails.

Would make inspection easier though!

That's what Rotax recommend on the engine and is recommended generally for

things like fuel lines, but other rubber components (eg engine mounts which

have a fail safe mode) could be changed merely on condition.



I'm not changing my tyres every 5 years in the absence of any defects

otherwise!
