Applicability*9

This AD applies to SMA SR305-230 and SR305-230-1 reciprocating engines. These engines are installed on, but not limited to, Cessna 182, Maule M-7, and Piper PA-34 airplanes. Reason (d) European Aviation Safety Agency, (EASA), Emergency Airworthiness Directive No. 2006-0312-E, dated October 13, 2006 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. The event described in the EASA AD can also occur in flight which can result in loss of control of the airplane.

Compliance

Unless already done, do the following actions before further flight. (1) Determine the serial number (SN) of the ECU installed on the aircraft. Do not operate the engine if the ECU SN is 131 and below, except SN 70, 71, 83, and 88. (2) If the ECU SN is 131 and below, except 70, 71, 83, and 88, remove and replace the ECU with an ECU having a SN of 132 and above. FAA AD Differences (f) None. Other FAA AD Provisions (g) The following provisions also apply to this AD: (1) Alternative Methods of Compliance (AMOCs): The Manager, Engine Certification Office, has the authority to approve AMOCs for this AD, if requested using the procedures found in 14 CFR 39.19. (2) Airworthy Product: For any requirement in this AD to obtain corrective actions from a manufacturer or other source, use these actions if they are FAA-approved. Corrective actions are considered FAA-approved if they are approved by the State of Design Authority (or their delegated agent). You are required to assure the product is airworthy before it is returned to service. (3) Reporting Requirements: For any reporting requirement in this AD, under the provisions of the Paperwork Reduction Act, the Office of Management and Budget (OMB) has approved the information collection requirements and has assigned OMB Control Number 2120-0056.
