It is unlikely that MD would discontinue all but the N model of the 369 series. It is likely based upon Kaman's recent SEC filings that a deal with MD was close to being finalized which is a major stumbling block to a restart of production.
Given the loss of the ARH contract and the competition related to the LUH contract, in the event the LUH contract does not go to MD, Patriarch's investment is contingent upon a component overhaul/service business and sales of as many new models as necessary. To limit themselves to N models of the 369 would be unduly constraining.
Boeing owns the ability to sell the 369 series for military purposes which limits the market for new product placement of this aircraft to commercial.
Patriarch spent a lot of money and management has continued to be evasive with respect to an actual date that parts, components and support will improve. My bet is that things will continue to improve but that they are spending a considerable amount of resources on the LUH contract.
Even though the statistical probablility of winning LUH is not very high, in the event they win the contract, the resources necessary to improve support and service for the 369 series will continue to be limited. If you operate 900 series aircraft, hope for a LUH win as that will result in substantial product improvement. In the event you operate 369 series aircraft, hope they lose so you can become the most important customer to their business.
