Summary
We propose to adopt a new airworthiness directive (AD) for all 328 Support Services GmbH Model 328-100 airplanes. This proposed AD was prompted by a report indicating that undetected cracks may develop at the roll spoiler bearing arms. This proposed AD would require a one- time non-destructive test (NDT) inspection for cracks in the roll spoiler bearing arms and, if necessary, corrective actions. We are proposing this AD to address the unsafe condition on these products.
