Airworthiness Directive · Amendment 39-13828 · Cessna Aircraft Company Models 190, 195 (L-126A,B,C), 195A, and 195B Airplanes
Cessna Aircraft Company Models 190, 195 (L-126A,B,C), 195A, and 195B Airplanes
Superseded. A later AD replaced this one: AD 2004-21-08 R1. Comply with the one in force.
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.
The FAA adopts a new airworthiness directive (AD) for all Cessna Aircraft Company (Cessna) Models 190, 195 (L-126A,B,C), 195A, and 195B airplanes that are equipped with certain inboard aileron hinge brackets. This AD requires you to repetitively inspect the affected inboard aileron hinge brackets for cracks or corrosion and replace them if found cracked or corroded. Replacement with aluminum brackets would terminate the need for the repetitive inspections. This AD results from 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.
To address this problem, you must do the following:
| Actions | Compliance | Procedures |
|---|---|---|
| (1) Inspect each P/N 0322709 and P/N 0322709-1 inboard aileron hinge bracket or any other bracket made from magnesium for cracks or corrosion | 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. |
| (2) Replace any cracked or corroded inboard aileron hinge bracket (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 | Use the procedures included with the FAA-approved replacement and the FAA-approved maintenance manual. This could include Cessna parts, supplemental type certificate (STC) parts, or parts manufacturer approval (PMA) parts, etc. |
| (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 | Use the procedures included with the approved replacement and the FAA-approved maintenance manual. This could include Cessna parts, STC parts, or PMA parts, etc. |
The aircraft, engines and makers this AD names, by the model designations in its text. A model listed here may still be outside the AD's serial ranges.
