Airbus is sitting on more WIP than expected. The engine supply situation is vexing single-aisle deliveries. Cabin fixtures are slowing twin-aisle deliveries. We have been watching this for some time. The supply chain problem is industry-wide. What does this look like? Here's a model that lets you peel back the layers to see where the WIP stands and which operators are being impacted. The data is based on our production and delivery tracker. The table on the left allows you to drill down from family into model, operator, and tail number. Getting a handle on the engine supply situation can be accomplished by clicking on the A220 or A320 Family. This shows the split between these two programs on the overall GTF volume. Note the engine volume is 2X - twice the number of aircraft listed. This model will be updated daily. The refresh box will advise you when it was last updated.
