APU?
JJ:
[1] APU normally not used in flight (so no reason it would take the tail off near TOC).
[2] The AD you refer to was issued in 2005, so 10 years have elapsed for the directive to have been complied with.
[3] Russia now acknowledging explosive residue - quite distinct signature from fuel-fed detonation.
