Mr. Maurice Quinn:

-----but we have certainly done a huge amount of research on this in preparation for today's meeting. Before one puts a piece onto an aircraft, whatever work needs to be done must be done and it is done on a just-in-time basis. One would not do it on an ongoing basis. When we did not give certificates, we also did not want any liability attaching to the State for the parts. That is where there was an as-seen basis of sale.
