AS 33

Where to start?

AS-W20 wing angle of incidence wrong on many brand new ships. Many -20's required new control surfaces.

Numerous modern ships of all flavors with significant "spar waves". Same with gel coat that was failing from when shipped. If gliders were pickups, there would be class action lawsuits over these issues.

Recent bolt issues in Wankel engines.

Numerous examples of all brands where the as-built ship does not match the blueprints in either the composite structure or the hardware install.

Not that i could ever afford it, but I would never buy a brand new ship. All are one-off handbuilt with lots of opportunity for operator error.
