January 2015. While performing the preliminary inspection on a Cessna CE560EP aircraft; I found the inboard end of the L/H aileron contacting the wing rib directly inboard of the aileron. The rivets and screws retaining the balance weight cover were gouging into the rib. I notified Maintenance Control. I recorded the damage and contact between the aileron and structure. The aircraft was outside in -8 degree temperatures and snow. The initial response for Maintenance Control was to grind the aileron to get clearance; because it was the busy season and our operator really needed the aircraft. That was not even an option in my opinion. Maintenance Control had a Contract Engineering company draft an Engineering Order (E/O) in which we were to grind down the rivet contacting the rib; and grant the aircraft 300 hours flight time before the repair was made. I forwarded the information to our company Safety Representative Mr. X. I also discussed this E/O with a senior inspector and we both agreed that this was not a safe option. The later E/O was to grind the rivet down; and fly the aircraft under Ferry permit to get repaired properly. Two days later we performed the repair per the E/O to ensure the rivet could not impede the movement of the aileron and performed a Ferry Flight inspection. Three days after that; I was notified by Safety Representative Mr. X that the aircraft had flown to our Base Station for repairs and the aileron was found to be the wrong part number installed three years prior. The CE-560 Illustrated Parts Catalog (IPC) has had many changes over time with the 560 series aircraft. I don't understand how the paperwork was missed during initial install of the aileron. Are the pre-flight checklist procedures incomplete? How was this missed? Excessive cold. Aircraft damage. Flight cancelled.
A Line Aircraft Maintenance Technician (AMT) reports finding the inboard end of a left aileron contacting a wing rib directly inboard of the aileron on a Cessna CE-560EP aircraft. Rivets and screws retaining the balance weight cover were gouging into the rib. Aileron had been installed three years earlier; but was found to be incorrect for the aircraft.
