CESSNA AIRCRAFT COMPANY: Docket No. FAA-2004-18033; Directorate Identifier 2004-CE-16-AD.

Airworthiness Directives; Cessna Aircraft Company Models 190, 195, 195A, and 195B Airplanes

SUMMARY: The FAA proposes to adopt a new airworthiness directive (AD) for all Cessna Aircraft Company (Cessna) Models 190, 195, 195A, and 195B airplanes that are equipped with certain inboard aileron hinge brackets. This proposed AD would require you to repetitively inspect the affected inboard aileron hinge brackets for cracks or corrosion and replace them if found cracked or corroded with brackets that are not made from magnesium. Replacement would terminate the need for the repetitive inspections. This proposed AD is the result of several reports of cracks and corrosion found on the magnesium aileron hinge brackets. Magnesium is known to be susceptible to corrosion. We are issuing this proposed AD to detect and correct corrosion damage to the inboard aileron hinge brackets. Such damage could result in the brackets cracking across the bearing boss and could lead to the aileron separating from the airplane with consequent reduced or loss of control of the airplane

When Is the Last Date I Can Submit Comments on This Proposed AD?
   (a)     We must receive comments on this proposed airworthiness directive (AD) by September 10, 2004.
   
What Other ADs Are Affected by This Action?
   (b)     None.

What Airplanes Are Affected by This AD?
   (c)     This AD affects Models 190, 195, 195A, and 195B airplanes, all serial numbers, that are:
    (1)     certificated in any category; and
    (2)     equipped with at least one part number (P/N) 0322709 or P/N 0322709-1 inboard aileron hinge bracket.

What Is the Unsafe Condition Presented in This AD?
(d)    This AD is the result of several reports of cracks and corrosion found on the magnesium aileron hinge brackets. Magnesium is known to be susceptible to corrosion. We are issuing this AD to detect and correct corrosion damage to the inboard aileron hinge brackets. Such damage could result in the brackets cracking across the bearing boss and could lead to the aileron separating from the airplane with consequent reduced or loss of control of the airplane.
