AD 2007-24-06 Airworthiness Directives; Societe de Motorisations Aeronautiques (SMA) SR305-230 and SR305-230-1 Reciprocating Engines
Applicability*9
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. Reason (d) European Aviation Safety Agency (EASA) AD 2007-0033, dated February 13, 2007, states: Over a period of time, the alteration of one electronic control unit (ECU) electronic component can cause a rapid uncontrolled power increase. Several occurrences have already been reported during engine start or during engine warm-up. This condition, if not corrected, could result in the loss of control of the aircraft if the pilot fails to react appropriately by switching to the mechanical backup mode. We are issuing this AD to prevent a rapid uncontrolled power increase and possible loss of control of the airplane.
Compliance
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. FAA AD Differences (f) 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. Other FAA AD Provisions (g) Alternative Methods of Compliance: The Manager, Engine Certification Office, FAA, has the authority to approve alternative methods of compliance for this AD, if requested using the procedures found in 14 CFR 39.19. Related Information (h) Refer to EASA AD 2007-0033, dated February 13, 2007, for related information.
