This looks to me like the ultimate solution
This is of course the proposed response after the Embry Riddle Piper Arrow lost a wing.
I can think of only one thing which EASA has done (and delivered on) since it got going about 10 years ago: the grandfathering of modifications. For example if somebody in Germany got a German CAA approval for some exhaust system (a Major mod, of course) this exhaust can now be installed on any EASA-reg plane.
But there is no central database of modifications, so this is partly useless.
The UK CAA has a database here. If you type in e.g. TB20 in the aircraft type, you get what is obviously a miniscule % of what has been actually done, so the database is obviously very incomplete. It stopped being updated at EASA-time; approx 2003.
I believe Germany has one too. Does anybody have the URL?
Otherwise, one might try contacting the (usually American) manufacturer of the equipment and ask if they sold any to Europe, and then try to extract information as to who, and then try to extract information from the (usually) avionics shop which did the mod, and they will want some money for the stuff… anything up to 4 figures if they did any real work on it.
Since I had a bit of a hard time starting the Cherokee 180 yesterday, I started to wonder about the aux fuel pump.
According to the (50 year old) owners handbook:
No mention of engine starting.
In the checklist section, it however shows aux fuel pump “on” before engine start.
Yet, in that manual, they never advise to switch it off after starting, and then back on before takeoff (as they do in later POHs, say for the Archer II). I actually dislike that, since if followed strictly, it means not checking at all whether the engine will run on the engine driven fuel pump alone.
Anyway, that’s what the “book” says, and leads me to believe that the only reason for switching it on before starting is to not have to do it before takeoff.
Got me wondering: does the aux fuel pump on these carburetted Cherokees actually do anything to aid in cold starting? (I obviously has a manual primer for priming the engine.) Does someone know?
