Narrative:
I was assigned to train several new mechanics on the task of engine rigging work card. Upon completion of the task; the trainees; quality assurance (qc) and I failed to notice the condition rod coming from the nacelle quadrant to the mechanical fuel controller (mfc) was installed on the opposite side of the mfc condition arm. The engine was trimmed and ran fine and flew for two months without any problem. At heavy check; the error was discovered and the supervisor was notified. The rod end was repositioned to its correct location. I overlooked the rod being installed on the opposite side. Avoid training several mechanics at one task and pay attention to detail of work being performed.

Title: An Aircraft Maintenance Technician Trainer was informed; after training several new mechanics on DHC8-300 Engine Rigging; that he; the trainees and Quality Assurance failed to notice a Condition Rod from the # 2 Engine nacelle quadrant to the Mechanical Fuel Control Unit; had been installed on the opposite side of the MFC Condition arm.
Narrative: I was assigned to train several new mechanics on the task of Engine Rigging Work Card. Upon completion of the Task; the trainees; Quality Assurance (QC) and I failed to notice the Condition Rod coming from the nacelle quadrant to the Mechanical Fuel Controller (MFC) was installed on the opposite side of the MFC Condition arm. The engine was trimmed and ran fine and flew for two months without any problem. At Heavy Check; the error was discovered and the Supervisor was notified. The rod end was repositioned to its correct location. I overlooked the rod being installed on the opposite side. Avoid training several mechanics at one task and pay attention to detail of work being performed.
