No. 70-147 or later EASA approved revision.

                7. Do not install on any EADS SOCATA TBM700 series aeroplane, NLG actuator hinge pins coming from the three defectives batches identified as EUR BC 21344-000-01, EUR BD 21344-000-01 & EUR SF 21344-000-01 on Nose Landing Gear P/N 21130-001-02.

             Note:  EASA Emergency AD 2006-0271-E dated 4 September 2006 refers. This AD supersedes EASA AD 2006-0226-E.
Compliance:     1. Before further flight after the effective date of this AD.

                2. Before further flight after the effective date of this AD.

                3. Before further flight after the effective date of this AD.

                4. Before further flight after the effective date of this AD.

                5. Any out of tolerance pin, before further flight after the effective date of this AD.

                Any pin from the defective batches, with satisfactory dimensional check, before
                3 October 2006.

                6. After any "Pancake" or "three-point" landing after the effective date of this AD.

                7. From the effective date of this AD.
             This Amendment becomes effective on 8 September 2006.
Background:  This AD results from one report of a Nose Landing Gear (NLG) hinge pin rupture that caused an uncommanded NLG retraction.

             Investigations identified the unsafe condition as that resulting from an incomplete thermal treatment done on three hinge pin batches lowering their mechanical properties with a high risk of deformation under service loads.

             These AD requirements are first to identify the concerned NLG and second to detect the defective hinge pins on aircraft and subsequently carry out replacement of those pins prior to pin rupture.

             This amendment is issued to extend the landing gear applicability as listed in the original issue of this AD.

   The original issue of this AD became effective on 26 July 2006.
