We are issuing this AD to prevent engine exhaust leaks, which could lead to uncontrolled engine fire, harmful exhaust gases entering the cabin resulting in crew incapacitation, and damage to the airplane. (f) Compliance Comply with this AD within the compliance times specified, unless already done. (g) Required Actions (1) For all engines, perform an initial exhaust system inspection within 10 hours time in service (TIS) after the effective date of this AD as follows: (i) Use the Required Action, paragraph 1. of Lycoming Engines Mandatory Service Bulletin (MSB) No. 627C, dated November 17, 2016, to do the inspection. (ii) For any part that fails the inspection required by paragraph (g)(1)(i) of this AD, before further flight, replace the failed part with a part eligible for installation. (iii) Use the Required Action, paragraph 3. of Lycoming MSB No. 627C, dated November 17, 2016, to submit a survey to LycomingEngines within 10 days of performing the inspection. (2) For all engines, perform an initial torque check of the exhaust system flange nuts within 10 hours TIS after the effective date of this AD, or within 100 hours TIS after the last exhaust system maintenance (ESM), whichever occurs later, as follows: (i) Use the Required Action, paragraph 2. of Lycoming Engines MSB No. 627C, dated November 17, 2016 to torque check the flange nuts. (ii) For any part that fails the check required by paragraph (g)(2)(i) of this AD, before further flight, replace the failed part with a part eligible for installation. (iii) Use the Required Action, paragraph 3. of Lycoming MSB No. 627C, dated November 17, 2016, to submit a survey to Lycoming Engines within 10 days of performing the check. (3) For all engines with 1,000 hours TIS or less since the last ESM: [[Page 26985]] (i) Repeat the actions required by paragraphs (g)(1)(i) through (iii) of this AD inclusive, every 25 hours TIS since the last ESM, or exhaust system inspection, whichever occurs later. (ii) Repeat the actions required by paragraphs (g)(2)(i) through (iii) of this AD inclusive, every 100 hours TIS after the last ESM, or torque check of the exhaust system flange nuts, whichever occurs later. (4) For all engines with more than 1,000 hours TIS since the last ESM: (i) Repeat the actions required by paragraphs (g)(1)(i) through (iii) of this AD inclusive, every 50 hours TIS since the last ESM, or exhaust system inspection, whichever occurs later. (ii) Repeat the actions required by paragraphs (g)(2)(i) through (iii) of this AD inclusive, every 100 hours TIS since the last ESM, or torque check of the exhaust system flange nuts, whichever occurs later. (h) Definitions For the purposes of this AD, ESM is any maintenance that requires the removal and replacement of any exhaust system pipe or turbocharger mounting bracket, or the re-torqueing of the exhaust flange mounting nuts.(i) Terminating Action The requirement in Required Action paragraph 3., to submit a survey to Lycoming Engines ends one year after the effective date of this AD, but, the exhaust system inspections in Required Actions paragraph 1., and torque checks of the exhaust system flange nuts, in Required Actions paragraph 2., are still required.
