Effective Date (a) This airworthiness directive (AD) becomes effective April 19, 2010. Affected ADs (b) None. Applicability (c) This AD applies to certain serial numbers (S/Ns) of Kelly Aerospace Energy Systems, LLC (KAES) rebuilt turbochargers listed by part number (P/N) in the following Table 1 of this AD. The affected S/Ns are listed in Table III of Kelly Aerospace Energy Systems, LLC Service Bulletin (SB) No. 039 A, dated February 10, 2010. Table 1--Part Numbers of Rebuilt Turbochargers Affected 406610-9005 406610-9015 406610-9018 406610-9019 406610-9020 406610-9021 406610-9025 406610-9026 406610-9028 406610-9029 406610-9030 406610-9032 407810-9001 406990-9004 408610-9001 409170-9001 409680-9011 465680-9001 465680-9004 465680-9005 465930-9002 465930-9003 465292-9002 465292-9004 465398-9002 407540-9003 466881-9001 466642-9001 466642-9002 466642-9005 466304-9003 600572-9000* 600573-9000* 600574-9001* 600575-9001* 600575-9002* 600576-9000* 600700-9001* 600803-9001* 600803-9002* N/A N/A * P/Ns with an asterisk may have a CF prefix. These rebuilt turbochargers are installed on, but not limited to, the engines and aircraft listed in Table IV of Kelly Aerospace Energy Systems, LLC SB No. 039 A, dated February 10, 2010. Unsafe Condition (d) This AD results from three reports of infant mortality turbine wheel failure in rebuilt turbochargers, since June of 2007. We are issuing this AD to prevent separation or seizure of the turbocharger turbine, which could result in full or partial engine power loss, loss of engine oil, and smoke in the airplane cabin. Compliance (e) You are responsible for having the actions required by this AD performed within 10 hours time-in-service after the effective date of this AD, unless the actions have already been done. Turbocharger Removal From Service (f) Remove from service the rebuilt turbochargers listed by P/N in paragraph (c) of this AD that have a S/N listed in Table III of Kelly Aerospace Energy Systems, LLC SB No. 039 A, dated February 10, 2010. Installation Eligibility of Removed Turbochargers (g) Removed turbochargers listed in Table III of Kelly Aerospace Energy Systems, LLC SB No. 039 A, dated February 10, 2010, are eligible for installation once they are overhauled by an FAA- approved repair station. That overhaul must include replacing the turbine wheels listed by P/N in Table II of Kelly Aerospace Energy Systems, LLC SB No. 039 A, dated February 10, 2010, replacing the turbine wheel mating bushings, and marking the attached Return To Service Tag with this AD number, which is AD 2010-07-08. Installation Prohibition (h) After the effective date of this AD, do not install any of the turbochargers listed in Table III of Kelly Aerospace Energy Systems, LLC SB No. 039 A, dated February 10, 2010, unless the turbocharger is overhauled as specified in paragraph (g) of this AD. Alternative Methods of Compliance (i) The Manager, Atlanta Aircraft Certification Office, has the authority to approve alternative methods of compliance for this AD if requested using the procedures found in 14 CFR 39.19. Special Flight Permits (j) Under 14 CFR 39.23, we are limiting the special flight permits for this AD by the following conditions: (1) Use of minimum crew. (2) Flight made during daytime, using visual flight rule conditions. (3) Maximum flight altitude of 12,000 feet mean-sea-level, based upon terrain.
