## Discrepancy

PILOT WAS TAKING OFF. THEY HEARD A LOUD BANG. ENGINE LOST POWER AND VIBRATED. PILOT TURNED AIRCRAFT AROUND AND LANDED PLANE ON RUNWAY. SHUT DOWN ENGINE AFTER LANDING. FOUND NR 1 CYLINDER BLOWN. THREE QTS OF OIL STILL IN ENGINE. CYLINDER IS AN ECI CYLINDER. IT DOES NOT APPLY TO AD 08-19-05 DUE TO THE SERIAL NUMBER BEING OUT OF RANGE AS CALLED OUT BY THE AD. THIS IS THE SECOND BLOWN ECI CYLINDER WE HAVE HAD THAT IS OUT OF THE SERIAL NR RANGE OF THE AD. I RECOMMEND THAT A REVISION BE MADE TO AD 08-19-05 THAT WILL COMPRISE OF A WIDER CYLINDER ASSY SERIAL NR RANGE.
