About Updraft Cooling ... good!
In order to build some time and get more comfortable on the plane, I did a X-country of about 97 Nm,
On the way back it was just starting to get bumpy (28 C up there) and it flew just as nice, however, I did notice the performance slacking off some 15Nm to BaraG (FASY), no amount of leaning or fiddling could get it back, and it was not the wind ...
Anyway, came in a little fast to 31 at the drome and decided on a go around.
Soon as I took power the whole contraption started spluttering and coughing, so I did a shortish tight circle and put her down, what a snap, crackle and pop to get the show to the hangar (slight uphill)
On shutdown, I saw lots of oil on the prop and all over. Totally peeved, made it secure and left for home, not wanting to deal with any more problems on that day.
Sunday - pulled the cowlings and was surprised to find the # 02 spark upper plug lead had separated and was loosely in place - must have been an oversight in my checking, since I cannot believe that this can come adrift by itself.
Much more interesting was that the # 03 fuel injector pipe had broken and was held together by the rubber insulation, not quite right off, but a light jiggle and it came apart smartly!
The underside of the top cowl was blue from the fuel dye and must have had copious quantity of fuel go over this.
The updraft cooling must have saved the day, since it appears to have blown the fuel vapours right out, what with the opposite side having a sparking wire at the ready to create havoc.
Must have been my lucky day, what with not catching fire & such ... :-) But that is mostly due to the Updraft cooling!
