ACTION:

Notice of proposed rulemaking (NPRM).

SUMMARY:

We propose to adopt a new airworthiness directive (AD) for certain Cessna Aircraft Company Models 172RG, R182, TR182, FR182, 210N, T210N, 210R, T210R, P210N, P210R, and T303 airplanes. This proposed AD was prompted by a report of a cockpit fire that appeared to originate from the area of the landing gear's hydraulic power pack system. This proposed AD would require you inspect the aircraft's hydraulic power pack wiring for incorrect installation, and if needed, correct the installation. We are proposing this AD to correct the unsafe condition on these products.

DATES:

We must receive comments on this proposed AD by October 26, 2012.

SUPPLEMENTARY INFORMATION:

Comments Invited

We invite you to send any written relevant data, views, or arguments about this proposal. Send your comments to an address listed under the ADDRESSES section. Include “Docket No. FAA-2012-0962; Directorate Identifier 2012-CE-033-AD” at the beginning of your comments.

Discussion

We received a report of an accident of a Cessna Aircraft Company Model 172RG airplane where a fire started in-flight on the cabin side of the firewall and rapidly accelerated. The fire originated from the area of the landing gear's hydraulic power pack system and resulted in a complete hull loss with reported injuries.

The investigation concluded that an in-flight fire may result from improper installation of the terminal lugs, improper installation of (or missing) terminal covers and associated wiring to the landing gear hydraulic power pack motor wiring, which was not properly protected or adequately secured. The cause for the rapid acceleration of the fire was indicative of the presence of flammable materials or a flammable material source near or in contact with the hydraulic power pack system within the aircraft's cockpit/cabin.

This style of hydraulic power pack is also used on Cessna Aircraft Company Models R182, TR182, FR182, 210N, T210N, 210R, T210R, P210N, P210R, and T303 airplanes.

This condition, if not corrected, could result in a fire in the aircraft's cockpit, damage and or loss of aircraft, and injuries and or fatalities.

Relevant Service Information

We reviewed Cessna Aircraft Company Service Letter MEL-29-01, dated July 14, 2012; and Service Letter SEL-29-01, dated July 16, 2012. The service information describes procedures for inspection of the aircraft's hydraulic power pack system for proper wire routing, protective cover, and hydraulic leaks, and if needed, installation of a protective cover and rerouting of wiring.

FAA's Determination

We are proposing this AD because we evaluated all the relevant information and determined the unsafe condition described previously is likely to exist or develop in other products of these same type designs.

Proposed AD Requirements

This proposed AD would require accomplishing the actions specified in the service information described previously.

Costs of Compliance

We estimate that this proposed AD affects 2,961 airplanes of U.S. registry.

We estimate the following costs to comply with this proposed AD:

Estimated Costs

ActionLabor costParts costCost per productCost on U.S. operators
Hydraulic power pack system wiring inspection1 work-hour × $85 per hour = $85Not applicable$85$251,685

We estimate the following costs to do any necessary hydraulic power pack terminal lug protective cap installation that would be required based on the results of the proposed inspection. We have no way of determining the number of aircraft that might need this installation:

On-Condition Costs

ActionLabor costParts costCost per product
Hydraulic power pack system wiring installation1 work-hour × $85 per hour = $85$29$114

Authority for This Rulemaking

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

We 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 this proposed regulation:

(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),

(3) Will not affect intrastate aviation in Alaska, and

(4) 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.
