## Discrepancy

DURING ANNUAL INSPECTION, TAILPIPE REMOVED.  LARGE CRACK AT ONE OF THE UPPER WELDS NEAR TURBOCHARGER MATING FLANGE WAS NOTED.  CRACK WAS OPEN .1250 INCH WIDE AND EXTENDED THREE-FOURTHS OF THE WAY AROUND PIPE.  THIS PIPE IS PART OF STC SA2717S0 WHICH ELIMINATES REPETITIVE 50-HOUR DYE PEN. CHECKS OF STANDARD PIPER TAILPIPES PER AD 40-01-02.  STC RECOMMENDS SHAKING TAILPIPES BY HAND ON EACH PRE-FLIGHT.  THIS IS THE FIRST FAILURE OF THE MALLEN AEROSPACE TAILPIPES THIS AGENCY HAS SEEN SINCE STARTING TO INSTALL THEM IN MID-1990.
