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 1977, and was based on the known fatigue history of the "bathtub" fittings.

               Amdt 1 was issued by Telex on 24 May 1979, and reduced the inspection threshold and interval for most models following an in-flight failure of an outer wing fitting on a King Air 65-90 aeroplane in Canada, and issue of Canadian emergency AD
               CF 79-06.

               This Amendment results from a review of the AD which confirmed the need for the requirement and the appropriateness of the inspection intervals. It consolidates AD/BEECH 90/47 and AD/BEECH 90/48 Amdt 1 into a single AD. The applicability has been curtailed to exclude later production aircraft which have clevis fittings in lieu of the "bathtub" type fittings. The requirements have been aligned with the Beechcraft SIRM to the extent possible; and the use of eddy current inspection of the "bathtub" is allowed as an optional alternative to fluorescent dye penetrant, with a corresponding increase in the repetitive inspection interval. Since the E90 shares the same fittings as the earlier models, the same inspection intervals also apply; this was overlooked when Amendment 1 was issued. The model F90 has also been added, it uses different fittings for which the SIRM inspection procedures and intervals have been adopted.
