The forward outboard, lower wing spar caps were found cracked. The cracks-on both left and righthand assemblies-radiated out from the fourth Huck rivet forward, passing through the wing attach hinge. This aircraft was inspected 15 months /404.2 hours ago by eddy current. No cracks were found at that time. Wing lower spar cap part numbers: l/h: 000-110012-1; r/h: 000-110012-2.

Key Takeaways:
Structural integrity issues were identified in Beechcraft King Air (cracked wing spar caps, previously undetected) and Piper Seminole (cracked nose cone spar, not covered by current ADs).
Component reliability concerns included recent "weather checking" failures in new Cessna 172R tire tubes and a loose turbocharger oil line on a Cirrus SR22.
Cessna turbocharged piston twin exhaust systems remain a critical safety concern, with a history of failures and current FAA reports of improper inspections despite an existing AD.
