AD 2013-08-14 78 FR 27005 Active

We are superseding an existing airworthiness directive (AD) for certain Revo, Incorporated Models COLONIAL C-1, COLONIAL C-2, LAKE LA-4, LAKE LA-4A, LAKE LA-4P, and LAKE LA-4-200 airplanes. That AD currently requires a one-time, dye-penetrant inspection of the horizontal stabilizer attachment fitting and repetitive visual inspections of the fitting for any evidence of fretting, cracking, or corrosion (with necessary replacement and modification); replacement of the fitting upon reaching the 850-hours time-in-service (TIS) safe life; and reporting to the FAA the results of the initial inspection and any cracks found on repetitive inspections. This new AD requires the same actions of AD 2005-12-02 except using revised service documents and procedures, adds Model COLONIAL C-1 airplanes to the Applicability, and adds an optional terminating action for the requirements. This AD was prompted by a report from Revo, Incorporated that, while the drawing numbers are different, the attachment fittings on the Model COLONIAL C-1 airplanes are identical in every other respect to those installed on the airplanes referenced in AD 2005-12- 02. We are issuing this AD to correct the unsafe condition on these products.
