Requirement:	Onetime Visual Inspection of Turbocharger1. Carefully remove the "V'' band clamp from around the turbocharger turbine housing at the turbocharger exhaust outlet, taking care not to move the exhaust tube and tailpipe assembly.2. Visually inspect the area that was captured by the "V'' band clamp. Use a feeler gauge at the split line between the turbine housing flange and the exhaust tube flange all around the circumference.3. The maximum gap must not exceed 0.005 inch.4. Replace any turbocharger that exceeds the 0.005 inch maximum gap, with a serviceable turbocharger.5. If the maximum gap is not exceeded, metal stamp a 1/8'' upper case "I'' on the side of the turbocharger discharge flange. Information on the stamping location can be found in the MSBs referenced in this Directive.Definition: For the purpose of this Directive, a serviceable turbocharger is one that is not listed in the suspect SN lists of the Lycoming Engines MSB or KAPS MSBs referenced in this Directive, or one that passes the visual inspection in this Directive.Note 2: FAA AD 2008-08-17 dated 10 April 2008 refers.
Compliance:	For Requirements 1, 2, 3 and 5: Within 10 hours time-in-service or at the next regular inspection interval, after the effective date of this Directive, whichever occurs first, unless previously accomplished.For Requirement 4: Before further flight.
	This Airworthiness Directive becomes effective on 13 May 2008.
