Societe de Motorisations Aeronautiques (SMA) SR305-230 and SR305-230-1 Reciprocating Engines
This AD applies to SMA SR305-230 and SR305-230-1 engines equipped with an electronic control unit (ECU) having one of the following part numbers (P/Ns): SF01160009-0, SF01160011-0, SP01160013, SP01160051-0, SP01160051-1, SP01160051-2, SP01160051-3, SP01160051-4, SP01160051-5, SP01160089-0, SP01160089-1, SP01160089-2. These engines are installed on, but not limited to, Cessna 182 series airplanes with Supplemental Type Certificate SA03302AT applied.
We are superseding an existing airworthiness directive (AD) for the products listed above. This AD results from mandatory continuing airworthiness information (MCAI) provided by the European Aviation Safety Agency (EASA) 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) Before further flight, check if the ECU has a P/N listed in the Applicability section of this AD and a serial number (SN) of 131 or below, except SNs 70, 71, 83, and 88. If it does, then do not operate the engine.
(2) Remove and replace the ECU with an ECU P/N SP01160089-3, using SMA Service Bulletin (SB) No. SB-01-76-005, dated December 15, 2006.
(3) No later than 30 days after the effective date of this AD, replace all remaining affected P/N ECUs with an ECU P/N SP01160089-3, using SMA SB No. SB-01-76-005, dated December 15, 2006.
(4) After the effective date of this AD, do not install a spare ECU having a P/N listed in the Applicability section of this AD as a replacement part on any SMA SR305-230 or SR305-230-1 engine.
This AD differs from the Mandatory Continuing Airworthiness Information (MCAI) and/or service information as follows:
(1) EASA AD No. 2007-0033 requires compliance with the AD by March 31, 2007.
(2) This AD, written later, requires compliance within 30 days after the effective date of the AD.
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.
