## Discrepancy

IN RESPONSE TO AD 2005-26-10 ISSUED BY THE FAA, INSPECTED AIRCRAFT TO DETERMINE IF ANY OF SUSPECT SN CYLINDERS INSTALLED.  FOUND 2 CYLINDERS ON LT ENGINE WERE PART OF THE AD REQUIREMENT FOR REPLACEMENT. ON CLOSER EXAMINATION OF ONE OF THESE CYLINDERS (NR 3), FOUND A CRACK EXTENDING FROM THE SPARK PLUG HOLE AROUND THE EXHAUST PORT AND PARTIALLY AROUND THE BARREL.  THERE WAS A SIGNIFICANT LEAK OF COMPRESSION.  BOTH CYLINDERS ARE PRESENTLY BEING REPLACED.  ALL OTHER CYLINDERS MADE BY ECI AND ON OUR AIRCRAFT WILL BE MONITORED CLOSELY AS REPLACE THEM ALL PER THE AD SCHEDULE.
