Notice of proposed rulemaking (NPRM).

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.
