SASless: conflict of interest because the wife of the NTSB investigator was responsible for the security of the parts (that have gone missing).
Secondly the Materials report caused the NTSB to shift the investigation to the paperwork discrepancies (Carson) and away from the engine fuel control issue (and the missing parts). Don't you think the NTSB were getting hot under the collar about these (missing) parts?
The mod that changed the 40 micron to the 6 micron filter undertaken by the mil appears 'not' to have been undertaken by this operator on these engines?
Have the fuel control modules/units for these engines ever been found or stripped and investigated??
