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.003.png)AD/S-PUMA/39\n\nAmdt 1\n\n  \nPilot and Co-Pilot Cockpit Pedal Unit 13/2001\n\nDM\n\nApplicability: Model AS 332 C, C1, L, L1, and L2 helicopters equipped with pedal adjustment lever part number 332A27-2344-20 of the pilot’s and co-pilot’s cockpit pedal unit assemblies, and without Modification 0726179 incorporated (ASB 67.00.20).\n\nRequirement: 1.
