Federal Aviation Administration (FAA), Department of Transportation (DOT).
Final rule.
We are adopting a new airworthiness directive (AD) for certain Cessna Aircraft Company (Cessna) Models 182Q and 182R airplanes that are equipped with Societé de Motorisations Aéronautiques (SMA) Aircraft Diesel Engine (ADE) Model SR305–230–1 or Model SR305–230 converted to Model SR305–230–1 installed under Supplemental Type Certificate (STC) SA03302AT. This AD requires you to remove the intercooler and the intercooler inlet and outlet hoses, install a reworked intercooler and new intercooler inlet and outlet hoses, inspect hoses and clamp torques, repetitively inspect installation of the intercooler outlet and inlet hose assemblies for any displacement or damage of clamps or hoses, and, if necessary, replace any damaged clamps or hoses. This AD results from a report of two instances of induction hose disconnection occurring while in service, resulting in a loss of turbo boost and a significant loss of engine power. We are issuing this AD to detect and correct improper intercooler outlet and intercooler inlet hose assembly installations, which could result in loss of turbo boost and a significant loss of engine power. This failure could lead to an inability to maintain constant altitude in flight.
This AD becomes effective on March 27, 2009.
On March 27, 2009, the Director of the Federal Register approved the incorporation by reference of certain publications listed in this AD.

On November 6, 2008, we issued a proposal to amend part 39 of the Federal Aviation Regulations (14 CFR part 39) to include an AD that would apply to certain Cessna Models 182Q and 182R airplanes that are equipped with SMA ADE Model SR305–230–1 or Model SR305–230 converted to Model SR305–230–1 installed under STC SA03302AT. This proposal was published in the
We provided the public the opportunity to participate in developing this AD. We received no comments on the proposal or on the determination of the cost to the public.
We have carefully reviewed the available data and determined that air safety and the public interest require adopting the AD as proposed except for minor editorial corrections. We have determined that these minor corrections:
• Are consistent with the intent that was proposed in the NPRM for correcting the unsafe condition; and
• Do not add any additional burden upon the public than was already proposed in the NPRM.
We estimate that this AD affects 7 airplanes in the U.S. registry.
We estimate the following costs to do the replacements:
We estimate the following costs to do any inspection of the installation of the intercooler hose assembly that would be required:
We have no way of determining the cost of any necessary replacement that may be required as a result of any inspection.

Title 49 of the United States Code specifies the FAA's authority to issue rules on aviation safety. Subtitle I, Section 106 describes the authority of the FAA Administrator. Subtitle VII, Aviation Programs, describes in more detail the scope of the agency's authority.
We are issuing this rulemaking under the authority described in subtitle VII, part A, subpart III, section 44701, “General requirements.” Under that section, Congress charges the FAA with promoting safe flight of civil aircraft in air commerce by prescribing regulations for practices, methods, and procedures the Administrator finds necessary for safety in air commerce. This regulation is within the scope of that authority because it addresses an unsafe condition that is likely to exist or develop on products identified in this AD.
We have determined that this AD will not have federalism implications under Executive Order 13132. This AD will not have a substantial direct effect on the States, on the relationship between the national government and the States, or on the distribution of power and responsibilities among the various levels of government.
1. Is not a “significant regulatory action” under Executive Order 12866;
2. Is not a “significant rule” under the DOT Regulatory Policies and Procedures (44 FR 11034, February 26, 1979); and
3. Will not have a significant economic impact, positive or negative, on a substantial number of small entities under the criteria of the Regulatory Flexibility Act.
We prepared a summary of the costs to comply with this AD (and other information as included in the Regulatory Evaluation) and placed it in the AD Docket. You may get a copy of this summary by sending a request to us at the address listed under

49 U.S.C. 106(g), 40113, 44701.
(a) This AD becomes effective on March 27, 2009.
(b) None.
(c) This AD applies to Models 182Q and 182R airplanes, all serial numbers, certificated in any category, that are equipped with:
(1) Societé de Motorisations Aéronautiques (SMA) aircraft diesel engine (ADE) Model SR305–230–1 installed under Supplemental Type Certificate (STC) SA03302AT; or
(2) SMA ADE Model SR305–230 converted to Model SR305–230–1 (by incorporation of SMA Service Bulletin SB–01–76–002) installed under STC SA03302AT.
(d) This AD results from a report of two instances of induction hose disconnection occurring while in service on the air inlet manifold circuit, resulting in a loss of turbo boost and a significant loss of engine power. We are issuing this AD to detect and correct improper intercooler hose assembly installation, which could result in loss of turbo boost and a significant loss of engine power. This failure could lead to an inability to maintain constant altitude in flight.
(e) To address this problem, you must do the following, unless already done:
(f) Under 14 CFR part 39.23, we are limiting the special flight permits for this AD by the following conditions:
(1) Before flight, an inspection of hoses and clamps by a properly certificated mechanic reveals no damaged or disconnected hoses or clamps; and
(2) You fly by the most direct route to the site where the AD can be performed.
(g) The Manager, Atlanta Aircraft Certification Office (ACO), FAA, has the authority to approve AMOCs for this AD, if requested using the procedures found in 14 CFR 39.19. Send information to ATTN: Don O. Young, Aerospace Engineer, ACE–118A, Atlanta ACO, One Crown Center, 1895 Phoenix Blvd., Suite 450, Atlanta, Georgia 30349;
(h) You must use SMA SAFRAN Group Service Bulletin SB–C182–75–004, Revision No. Basic Issue, dated July 8, 2008, to do the actions required by this AD, unless the AD specifies otherwise.
