ACK 406 ELT Still Backordered
I just spoke with Aircraft Spruce and I'm #458 on their backorder list (order placed 4/19/11). They aren't expecting any to arrive until July, and it didn't sound like they were going to get enough then to fill the existing orders. They said that they've had orders on the books since '09, but they've only shipped 10 units so far (received 4/13/11). They also said that they will be calling all customers with outstanding orders before shipping to confirm that the unit is still needed.
I also called Gulf Coast Avionics and got on the waiting list there (today). They spoke with ACK last week and expect to get enough stock within the next two weeks to ship all outstanding orders. I'm dubious, but there's no harm in having an order in there since ACS will call before shipping the backordered unit.
