Unsafe Condition
Some Allowable Damage Limits and Repairs published in SRM Chapters 57-61-12 PB101 and 57-61-12 PB201 were de-validated starting from the SRM revision issued on January 2009. This may result in failure or disbonding of the repairs on the inner aileron panels, leading to flutter coupling of the free aileron part.
