Societe de Motorisations Aeronautiques (SMA) SR305-230 and SR305-230-1 Reciprocating Engines
This AD applies to Societe de Motorisations Aeronautiques (SMA) SR305-230 and SR305-230-1 reciprocating engines with exhaust collector assembly part number (P/N) SF01080014-0. These engines are installed on, but not limited to, Cessna 182 series airplanes modified to supplemental type certificate AS03302AT.
We are adopting a new airworthiness directive (AD) for the products listed above. This AD results from Mandatory Continuing Airworthiness Information (MCAI) provided by the aviation authority of France to identify and correct an unsafe condition on SMA SR305-230 and SR305-230-1 reciprocating engines. The MCAI states the following:
Unless already done, do the following actions.
(1) Within 30 hours time-since-new (TSN), visually inspect the exhaust collector assembly, P/N SF01080014-0 in the area of the TIT probe mount weld for cracks.
(2) Before further flight, replace exhaust collector assemblies found cracked with a serviceable part.
(3) Within 10 hours time-since-last inspection (TSLI), repeat the actions specified in paragraph (e)(1) and (e)(2) of this AD.
(4) Within 50 hours TSN, replace the exhaust collector assembly with a serviceable part.
(5) Continue to inspect and replace exhaust collector assemblies as specified in paragraphs (e)(1) through (e)(4) of this AD.
(6) For the purpose of this AD, a serviceable exhaust collector assembly is a new exhaust collector assembly, or an exhaust collector assembly with fewer than 50 operating hours and no cracks.
This AD differs from the Mandatory Continuing Airworthiness Information (MCAI) and/or service information as follows:
(1) We require the initial inspection within 30 hours TSN instead of at 30 hours TSN.
(2) We require the repetitive inspections within 10 hours TSLI instead of at 40 hours TSN.
(3) We define a serviceable part.
The aircraft, engines and makers this AD names, by the model designations in its text. A model listed here may still be outside the AD's serial ranges.
