Summary
We propose to revise an existing airworthiness directive (AD) that applies to 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. The existing AD currently requires you to repetitively inspect the affected inboard aileron hinge brackets for cracks or corrosion and replace them if cracks or corrosion is found. Replacement with aluminum brackets would terminate the need for the repetitive inspections. Since we issued AD 2004-21-08, the FAA, in recent months, has received reports of confusion between the casting number on the aileron hinge bracket and the part number (P/N) called out in the AD. This proposed AD would retain the actions of AD 2004-21- 08 while requiring future compliance following a revised service bulletin that clarifies the casting numbers and part numbers to be inspected. We are proposing this AD to correct the unsafe condition on these products.
