brush. This will simplify penetrant removal and minimise false indications. Care should be taken to ensure full coverage of the fillet radius and a similar distance (at least 5 mm) into the cylindrical portion of the counterbore, in particular on the side of the hole adjacent to the "bottom of the bathtub".
 COMMONWEALTH OF AUSTRALIA (Civil Aviation Regulations 1998), PART 39 - 105 CIVIL AVIATION SAFETY AUTHORITY
 SCHEDULE OF AIRWORTHINESS DIRECTIVES

           Note 4: No attempt should be made to polish out suspect indications, as this has led in the past to the obscuring of large cracks. Where suspect indications need to be confirmed, seek specialist NDT advice.

           Note 5: Inspection of the bolts and nuts is detailed in the current issue of AD/BEECH 65/57.

           Compliance:  Prior to exceeding the component hours' time in service listed in column (3) of the Inspection Schedule below, and thereafter at intervals not to exceed the component hours' time in service listed in column (4). Where the eddy current procedure is used the repetitive inspection interval in column (4) may be doubled.

           For models not listed in the Schedule, the Authority must be contacted.

           Note 6: Inspections carried out in accordance with previous issues of this or related ADs, satisfy the initial inspection requirements of this amendment.

           This Amendment becomes effective on 2 November 2000.

               Background:  The original issue of this Airworthiness Directive became effective on 30 June 1980, when a number of similar ADs were issued to cover the different Queen Air models. The inspection requirement was based on the known fatigue history of the "bathtub" fittings.

               Amendment 2 became effective on 22 March 1990, and resulted from the consolidation of the Beech 65 and 70 series Airworthiness Directives. The requirements were unchanged.

               Amendment 3 became effective on 12 January 1992. It consolidated AD/BEECH 65/22, 23, 24, 25 and 26, and aligned the requirements with the Beech SIRM to the extent possible. The repeat inspection interval was reduced for the Model 65-B80, and extended for most other models, based on a review of the fitting stress levels and service experience.

               This Amendment results from a review of the AD which confirmed the need
