Note: Socata Technical Instruction Nr 9081 is identical to kit OPT10 908100. Modification to aircraft in this serial number range, according to Technical Instruction Nr 9081, was directed under Requirement 3 of AD/TB10/1, Amdt 2 or earlier.
4. Modify, in accordance with Requirement 4, before 12000 flights or 8000 hours time in service, whichever occurs first.
Replace the modification at intervals not to exceed 12000 flights or 8000 hours time in service, whichever occurs first.
The technical requirements of the original AD remain unchanged. This amendment is effective from 14 September 1995.
Background: Modification and replacement of components in the wing to fuselage attachment structure is necessary to ensure the continued structural integrity of the joint. Repair of cracked structure is achieved by installing the appropriate modification.
Amendment 1 is made to allow for aircraft which have previously been modified according to the requirements of AD/TB10/1 Amdt 2 or earlier. The applicable kit for early production aircraft, which do not have a wing rear attachment, has been re- designated as OPT10 919800. There is, at present, no technical difference between this kit and kit OPT10 908100, applicable to later production aircraft.
