109. Elementary my dear Watson…

27/05/2014

Well, that was interesting, and goes to show why we should none of us be detectives. Our powers of observation are nil.

Encouraged by my wife Sue, I started looking back to see if we could identify when the damage to the cable occurred. We looked further and further back, and we can clearly see that it occurred some time between the 14 July, when it was okay, and 30 July when it wasn’t.

Here’s the evidence on 14 July…

No mark at all. Yo're looking at the cable running from top left to bottom right, roughly in the middle.

And on 30 July, you can make out the discolouration.

The fuselage is upside down in this picture, so you're looking at the cable running from bottom left to top right.

And in case you think it might be a shadow cast by the cable on the other side, here it is again a couple of days later…

A bit out of focus, but it's the cable running top left to bottom right, and you can clearly see the discolouration roughly in the middle...

We see what we want to see…

The fix? Well, the cable is spliced directly to the fitting at the bottom of the last picture, which means that the fitting itself will have to be taken off the aircraft. It’s the one that has the socket for the undercarriage leg on it, and of course there’s a risk that the actual fuselage all comes apart when at that point, so we’ll have to run a couple of ratchet straps round the fuselage in front and behind, then remove the undercarriage, then undo all the carefully adjusted cables that are connected to the fitting. Then the fitting will have to go to Theo to replace the cable (we were just congratulating ourselves on the fact that we’d ordered exactly the right amount so we’ll need to order more).

Then it will have to be load tested before we bring it back up here and reassemble, then realign the fuselage again.

Ho hum.
