Narrative:
As far as I know, I have not installed any parts wrong, and will work with air carrier/FAA to resolve this matter. Callback conversation with reporter revealed the following information: the reporter stated when the problem was discovered the engine had been in service for greater than a yr and was removed for another mechanical problem. The reporter said the shop dismantled the engine and discovered 3 incorrect lever arms installed. The reporter said it was believed the arms were installed at a line station during a stator vane rig job.
