Airworthiness Directives; Cirrus Design Corporation Model SR20 and SR22 Airplanes
AGENCY: Federal Aviation Administration (FAA), Department of Transportation (DOT).
ACTION: Notice of proposed rulemaking (NPRM).
SUMMARY: The FAA proposes to adopt a new airworthiness directive (AD) for certain Cirrus Design Corporation (CDC) Model SR20 and SR22 airplanes. This proposed AD would require you to inspect the fuel line and wire bundles for any chafing damage; if any chafing damage is found, replace any damaged fuel line and repair any damaged wires or sheathing of the wire harness; and install the forward loop clamp, fuel line shield, aft loop clamp, and anti-chafe tubing. This proposed AD results from reports of fuel line leaks resulting from wire chafing on the fuel lines. We are issuing this proposed AD to detect and correct damage to the fuel line and wire bundles, which could result in fuel leaks. This failure could lead to unsafe fuel vapor within the cockpit and possible fire.

Discussion
What events have caused this proposed AD? The FAA has received two reports of fuel line leaks within a compartment in the center console of Model SR22 airplanes. This compartment is drained to the belly of the aircraft. Investigation found that the leaks resulted from wire chafing on the fuel lines.
What is the potential impact if FAA took no action? This condition, if not corrected, could result in unsafe fuel vapor within the cockpit and possible fire.
Relevant Service Information
Is there service information that applies to this subject? We have reviewed Cirrus Design Corporation Service Bulletin SB 2X-28-04 R1, Issued: November 1, 2005, Revised: November 8, 2005.
What are the provisions of this service information? The service information describes procedures for:
Fuel line chafing inspection; and
Protective measures to prevent a potential chafing condition.
FAA's Determination and Requirements of the Proposed AD
Why have we determined AD action is necessary and what would this proposed AD require? We are proposing this AD to address an unsafe condition that we determined is likely to exist or develop on other products of this same type design. The proposed AD would require you to inspect the fuel line and wire bundles for any chafing damage; if any chafing damage is found, replace any damaged fuel line and repair any damaged wires or sheathing of the wire harness; and install the forward loop clamp, fuel line shield, aft loop clamp, and anti-chafe tubing. The proposed AD would require you to use the service information described previously to perform these actions.
Costs of Compliance
How many airplanes would this proposed AD impact? We estimate that this proposed AD affects 2,135 airplanes in the U.S. registry.
What would be the cost impact of this proposed AD on owners/ operators of the affected airplanes? The manufacturer will cover parts and labor costs if the work is done within the standard airplane warranty period and the work is done at any of the manufacturer's authorized service centers.
Authority for This Rulemaking
What authority does FAA have for issuing this rulemaking action? 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 rulemaking action.
Regulatory Findings
Would this proposed AD impact various entities? We have determined that this proposed AD would not have federalism implications under Executive Order 13132. This proposed AD would 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.
For the reasons discussed above, I certify that the proposed regulation:
-
Is not a ``significant regulatory action'' under Executive Order 12866;
[[Page 72947]]
-
Is not a ``significant rule'' under the DOT Regulatory Policies and Procedures (44 FR 11034, February 26, 1979); and
-
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 regulatory evaluation of the estimated costs to comply with this proposed AD. See the ADDRESSES section for a location to examine the regulatory evaluation.
