I have to say that I've never known an AOG go on for so long. Structural damage caused by a landing incident, yes - viz 757s at Funchal, Gib etc - but for an AOG, it is taking a huge length of time to get it fixed. I appreciate that it isn't your every-day AOG, but I've known whole undercarriage legs get replaced and even a heavily corroded wing spar repaired quicker than this.
