               1. For all applicable aeroplanes, except those equipped with an anti-skid/power brake system, replace each brake shuttle valve with part number (P/N) MS28767- 4 brake shuttle valve in accordance with the ACCOMPLISHMENT INSTRUCTIONS section of Fairchild Aircraft SB No. 226-26-003 Revision 4, or Fairchild Aircraft SB No. 227-26-002, as applicable.

               2. For all applicable aeroplanes, install a shield over the hydraulic lines in accordance with the ACCOMPLISHMENT INSTRUCTIONS section of Fairchild Aircraft Service Bulletin No. 226-26-003 Revision 4, or Fairchild Aircraft SB No. 227-26-002, as applicable.

3.        For all aeroplane models within the SA226 series, replace the rubber fuel hose with a metal device in accordance with the ACCOMPLISHMENT INSTRUCTIONS section of Fairchild Aircraft SB No. 226-26-003 Revision 4.

4.        No person shall install any brake shuttle valve that is not a P/N MS28767-4 brake shuttle valve or a fuel hose that is made of rubber.

           Note: FAA AD 2002-08-02 refers superseding FAA AD 2001-20-14.

           Compliance: For Requirement 1, 2 and 3: Unless already complied with in accordance with the original issue of this Directive; within 500 hours time- in-service (TIS) from the effective date of this Directive, or within 6 months from the effective date of this Directive, whichever occurs first.

           For Requirement 4: From 6 March 2002, the date of original issue of this Directive. This Amendment becomes effective on 3 July 2002.

           Background: This Directive has been amended to reflect the contents of FAA AD 2002-08-02 which removes the applicability of the Model SA226-T(A) aeroplane and adds certain Model SA226-T and Model SA227-AC serial numbers to the applicability.

           The manufacturer issued Service Bulletins (SB) 226-26-003 and 227-26-002 on 1 March, 2000, that indicated a potential problem for a brake assembly to overheat due to a faulty brake shuttle valve causing the brake assembly to drag and overheat.
           Should this occur, there is a further potential for hydraulic or fuel line damage to occur if a overheated brake assembly is retracted into the main wheel well, with the possibility of a fire occurring if a hydraulic or fuel line is ruptured. This Directive is therefore issued to reduce the potential of a main gear wheel well fire occurring.

           The original issue of this Airworthiness Directive became effective on 6 March 2002.
