SOCATA

§ cost of compliance : It is specfied in the proposed AD: -"it would take about 3 work-hours per product to comply with the basic requirements of this proposed AD........any necessary follow-on actions would take about 15 work-hours". according to SOCATA, inspection would take 0.5 work-hour. if necessary, rivets replacement would never take more than 5 work-hours. -"Required parts would cost about $300 per product......and require parts costing $2,000 for a cost of $3,200 per product" If parts are necessary, only rivets and shims are required and their cost is negligible. The costs of compliance of the AD2007-03-71 linked to the SB70-129 original issue are : "We also estimate that it will take 6 work-hours per product to comply with this AD........Required parts will cost about $5 per product" We agree with the rest of the AD.
