If the machine has had regular maintenance by a reputable engineer then the SIDs are no big deal just a little expensive for the first time.
We know this inspection will exceed the value of the aircraft.
Folks,
One thing we have found from experience is that even well maintained 100 series can have very difficult to detect corrosion. The area in question id in the main spar sandwich from the main fuselage attach point to the strut attach point.
Even with the tank out, it is very hard to detect, short of dismantling the multiple leaves of the spar t this point.
Having seen what I have seen, I would not buy a strutted Cessna unless the wings had been rebuilt, because this very insidious corrosion will happen to the best maintained aeroplane.
Does the SIDS doc. call up any particular inspection of the area, visual is not nearly good enough?
Tootle pip!!
