I mean look, I'm a new mooney owner, I know nothing of the struggle.
But I do ok with business...
Why even talk about new planes. Thats R&D dollars and theres no way to cover those expenses now. New planes wont make money. Massive capital tie up, no production ramp, demand is too low, etc.
Step one is what I see happening: Get the high margin business on solid footing; parts and Service. Parts production has to go up. Inventory is going to tie up all capital for the next 3-5 years. The fleet must stay in the air, or the game is over. Point, peroid, end of that topic.
Step two: Only after profitability with parts and service; New developements on existing platforms. If you are going to spend development dollars, make sure its where the fleet needs it. What thing does everyone know is worng, or know how to make better, but doesnt have the development / regulatory power to push through.
Step three: new training platform. When the team grows, develop a training platform. Low wing, fixed gear, hearty mooney for the training market, needs to be TAA to cover the commerical requirement in lieu of RG because no flight schools are buying an RG ever again.
Step four: continuous improvement on prior platforms. Stay current with Acclaim / Ovation (premium tier), Relaunch the J/K with 4banger, and continued trainer.
There is really no reason to go beyond a simple product offering and do it well. But it all starts with the high margin offerings which is parts and service. Getting past step 1 could take 5-10 years, just is what it is.
