Honestly, the engines and props are a pass through business for Van's. They likely mark it up a bit and resell it to the user, or more likely, simply act as an agent for the manufacturers, and never actually own the engine/prop inventory. That transactional pass through business (and price) likely won't be affected by the bankruptcy filing (unless I'm way off base). At least that's the way I would set it up if I was in Lycoming/Hartzell's position.
Here's the notice on Van's website:
Customers with deposits on engines/powerplants, propellers, and avionics
We are working with our engine, propeller, and avionics partners to develop our plans for these products and customers as soon as possible. We will update customers with these orders when we have been able to establish specific plans with each partner. Due to the volume and nature of these orders, we do not expect to have answers for these customers before mid-January. If we have meaningful information to share, we will update you sooner.
