Remove/inspect tailpipes for cracks, corrosion, holes or distortion every 12 months. Inspect/pressure test exhaust system every 12 months. Replace multi-segment V-band clamps every 500 hrs of operation. Remove exhaust system from slip-joints aft to all turbo- charger components every 2500 hrs of operation or 12 yrs whichever occurs first and send to approved repair facility. Inspect tailpipes for internal pitting and wall thickness especially at the outside radius, which is the thin section, and at support bracket. Inspect joints for freedom of movement and distortion. Inspect turbo header for internal pitting, warped and or cracked flow divider and thin sections. Some of the parts for this aircraft are Inconel. Although Inconel is a far superior metal, it is more difficult to inspect. Inconel tends to corrode from the inside without showing signs of flaking or bulging like stainless steel. The carbon on the inside of the exhaust parts should be removed to properly inspect the components. If the welds are developing pinholes the component may not pass an internal inspection. Slip fit stacks should be ordered as a complete assembly to ensure good joint integrity with smooth slip fits.
