When Does This AD Become Effective?
(a) This AD becomes effective on November 30, 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 (L-126A, B, C), 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.
What Must I Do To Address This Problem?
(e) To address this problem, you must do the following:
Actions

Initially inspect within the next 100 hours time-in-service (TIS) after November 30, 2004 (the effective date of this AD), unless already done. Repetitively inspect thereafter at intervals not to exceed 100 hours TIS until each bracket is replaced with an FAA-approved bracket that is made with aluminum.
Follow the procedures in Cessna Single Engine Service Bulletin SEB04-1, dated April 26, 2004.

(i) If replacement is with a bracket made from magnesium, do the 100-hour TIS interval repetitive inspections as required in paragraph (e)(1) of this AD.
(ii) If replacement is with an FAA-approved bracket that is made from aluminum, then no further inspections are necessary. These can be Cessna parts or non-Cessna parts.
Prior to further flight after any inspection where any cracked or corroded bracket is found. You may terminate the repetitive inspections required by this AD when all brackets are replaced with FAA-approved brackets that are made with aluminum, as specified in the service information.

(3) As terminating action for the repetitive inspections, you may replace all inboard aileron hinge brackets with FAA-approved brackets that are made from aluminum (as specified in paragraph (e)(2)(ii) of this AD) regardless if any corrosion or crack is found.
You may do this replacement at any time, but you must replace any corroded or cracked bracket prior to further flight after the applicable inspection where any corrosion or crack is found.
