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.

Robin Aviation Series Aeroplanes
AD/ROBIN/27 Amdt 2  Rudder Pedal Bars  1/2008

Applicability:  Model R 2100, R 2100 A, R 2112, R 2120 U, R 2160, R 2160 D, and R 2160 I aircraft, serial numbers 1 through 378; and aircraft not fitted with reinforced rudder bars part number (P/N) 27.40.31.010 and P/N 27.40.31.020.

                Model HR 200/100, HR 200/100S, HR 200/120, HR 200/120B, and HR 200/160 aircraft, serial numbers 1 through 378, and aircraft not fitted with reinforced rudder bars part number P/N 27.40.31.010 and P/N 27.40.31.020.

                Note 1:  This Directive is not applicable if reinforced rudder bars are already installed in accordance with a previous issue of this Directive.

                Note 2:  This Directive is not applicable to the R 2000 series aircraft manufactured by Alpha Aviation.  These aircraft are fitted with reinforced rudder bars at manufacture.
Requirement:       1. For Model R 2000 series aircraft, replace the left rudder bar P/N 27.23.05.010 and the right rudder bar P/N 27.23.05.020 with reinforced rudder bars part number P/N 27.40.31.010 and P/N 27.40.31.020 respectively, in accordance with Alpha Aviation Service Bulletin AA-SB27-003.

                   2. For Model HR 200 and R 2120 U aircraft, check the geometrical shape of both the rudder bars in accordance with Figure 1.  Maintain the rudder bars in the neutral position and measure distances G1, G2, and D1, D2 (the distance between the foot tubes and the front face of the frame box located under the seats).  The difference between G1 and G2, or D1 and D2 is the distortion.

                     a. If D1=D2 and G1=G2 (+/- 5mm), there is no significant distortion and no action is required, re-inspect at intervals not to exceed 500 hours time in service.

                     b. If the distortion is between 5mm and 10mm, re-inspect at intervals not to exceed 100 hours time in service, until replaced with reinforced rudder bars part number P/N 27.40.31.010 and P/N 27.40.31.020 in accordance with
                     AA-SB27-003.

                  c. If the distortion is equal to or greater than 10mm, replace both rudder bars in accordance with AA-SB27-003.
