Do the rules permit adding content on a Phriday?
Re BEgles pic at #23. We had 3 aircraft at the time I was involved. I can't remember which one it was but one had an extra frame in the tail cone area just aft of the back hatch. It was at least 6" longer. and not recorded on the BAe type records or drawings. This came to the fore when we were doing a waveguide installation so ended up with a set of templates for all 3 aircraft. I think the hole had been cut between two frames for the horn to poke out through a little window (too small to see in any pictures) and the wave guide that had all been brazed up and silver plated would not reach. Thank the lord for the short flexible bits!
The TuRD installation was also impacted by this difference and covered by a note on the drawings "fettle to fit". I don't think TuRD was fitted at the time of BEagles picture. It would have been a few weeks later.
