“Multiple second stage planet gears in at least one of Era’s 225s exhibit characteristics of degradation and spalling associated with the design defect that has been identified as a causal factor in the catastrophic failures involving Super Puma helicopters,” the company claims in its petition.
“While there are indeed fundamental differences between the two planet gear configurations, the characteristics of degradation are evident on both the parts identified for replacement (i.e., the ‘bad’ parts) and the parts identified for retention (i.e., the ‘serviceable’ parts). Era has determined that even those parts identified by Airbus Helicopters as ‘serviceable’ exhibit the same symptoms of failure that have necessitated the immediate removal and disposal of the parts that Airbus Helicopters has now admitted are defective and unsafe.”
