Topic-icon SENECA I in Argentina

Hi Diego;
My research shows that the 4th window was installed when the Seneca II was released. The Seneca II had club seating (the second and third row seats faced each other) and a 4570 pound maximum take off weight (MTOW) instead of the 4000 or 4200 pound MTOW for the Seneca I.
The II incorporated quite a few upgrade/changes including the higher MTOW, the club seating, turbocharged engines, redesign of the ailerons, addition of a rudder anti servo tab and the addition of a stabilator bob weight.

Thanks Steve, I understood the same about the Seneca II. I believe this fuselage might have been designed for a Seneca II, but fitted into one of the last Seneca I on the production run. I could not find any evidence of adding that 4th window after the plane was manufactured.

This Seneca has club seating, but also do the other 2 Seneca I that are siblings to this one (which were part of that smuggling run I mentioned), which have just 3 windows per side (LV-LIL and LV-LCW. But all these planes retain the standard MTOW of 4000/4200 pounds with the naturally aspirated Lycs.

LV-LIL has a nice mod on the engine cowlings, with 2 landing lights, one per side. See picture attached.

So far still pulling things apart on my plane. Next week I will put the order for all engine + landing gear spares with Aviation Parts. ELT will also be installed next week and the painter might start cleaning and polishing ... hopefully that will bring back some of the colors.

Best,

Diego

Another week went by and -LCZ is getting further ahead into overhauling. I also managed to talk to an old A&P mechanic that used to work on this plane and he told me that the 4th window we discussed earlier was added to the plane some 14 years ago. Still no entry on the logs can be found ... this is how we do things down here :ohmy:

So, the Seneca is up on jacks and landing gear will come out. All bolts will be replaced, new braking pads installed and both hydraulic hoses will be replaced. Corrosion mitigation will be done on the wells. New tires and tubes will also be installed.

All 4 fuel tanks have been unscrewed from the wings (took some real effort) and next week they will be taken off for cleaning and inspection. All structural screws from the tanks will be replaced too. Inspection plates were open and I got some good pictures from the pipes and aileron actuator.

2 painters also visited and I expect to get quotes from them next week. The idea is to do a deep cleaning/polish and then repaint the cheat stripe that was burnt by the sun (but in silver, not gold). I will probably paint the 2 cowls on each engine ... they are in bad shape. I will also paint a dark stripe on the leading edge of both wings (similar to de-icing boots) since the paint there is cracked.

We will also take down ailerons and flaps; bolts, uni-balls and some screws will be replaced.

Fun never ends ...

Diego

I'm not sure what I'm looking at but it sure looks like there is displacement of the black tube that has caused deformation of the bulkhead.
What is that part? LG actuator? Flap actuator tube??

Hola Steve ... is this the picture you are talking about:



... then it is the left wing aileron actuator. The black tube runs vertical inside the wing. I am getting concerned now ... where do you see the deformation?

Thanks!

Diego
