But another thought,
Run the company through a bankruptcy, recapitalize it appropriately. Drop the 520n, 600n, keep the 902 as well as the E using the new RR500 and the F models with a C30R3.
To compete with Robinson and the R66, start the C model back up.
Re-invigorate the spares business raising volumes and lowering pricing and costs with a drive to increase hours flown.
Sell to larger player once fixed.
Buy another company, repeat process, retire at 72 or maybe 76 if things keep going as they are with respect to retirement plans in the world.
