The AD requires that the action set out in the requirement section (being action that the delegate considers necessary to correct the unsafe condition) be taken in relation to the aircraft or aeronautical product mentioned in the applicability section: (a) in the circumstances mentioned in the requirement section; and (b) in accordance with the instructions set out in the requirement section; and (c) at the time mentioned in the compliance section.\n\n![](image.001.png)  \n\nAerospatiale (Socata) TBM 700 Series Aeroplanes\n\nAD/TBM 700/28\n\nAmdt 2\n\n  \nFuselage Skin Around the VHF1 Antenna 3/2004\n\nApplicability: Model TBM 700 aircraft, serial numbers 1 through 255, 257 through 267, and 270; equipped with a VHF antenna under the fuselage between frame C12 and C13.\n\nNote: Aircraft which have been reinforced in accordance with Socata Repair Sheet No. 70-017 or with change No. 70-150-53, depending on the serial number, as specified in Service Bulletin No. 70-111, are no longer affected by this Directive.\n\nRequirement: Inspect the fuselage skin around the VHF1 antenna in accordance with EADS Socata Service Bulletin TBM 700 No. 70-103 Revision 1, dated September 2003.\n\nAn amendment to the Aircraft Flight Manual is required.
