The design of the refuel/defuel panel illuminated placard was changed during 1997 from its original specification, to fill the cavity inside the placard with silicone to avoid moisture/fluid ingress. SAAB has reviewed the working procedure and has developed a placard filled with a bi-component silicone-based material to minimize the cavity inside the panels.                                                                                 |\n|             | The original issue of this Directive required the identification of the manufacturing date of the affected placard, a visual inspection of the placard for heat and/or burn marks and the installation of a new placard.                                                                                                                                                                                                                                                                                                                                           |\n|             | Following a request from an Australian operator and SAAB, EASA has revised AD 2008-0127 to identify the affected Vibrachoc (the part manufacturer) placard with P/N C4FL5031C001, instead of the corresponding SAAB P/N 9303719-001, which was (also) quoted inaccurately. In addition, EASA recognised that the original Directive did not allow installation of placards with a manufacturing date before 31/97; that has now been corrected. This Amendment reflects the EASA changes and recognises prior compliance with Requirement 1 of the original issue. |\n|             | The original issue of this Directive became effective on 28 August 2008.                                                                                                                                                                                                                                                                                                                                                                                                                                                                                           |\n\n![](image.001.png)  \nCharles Lenarcic  \nDelegate of the Civil Aviation Safety Authority\n\n15 August 2008","sortOrder":0},{"sectionNumber":"AD/SF340/107 Amdt 1","sectionType":"part","heading":"AD/SF340/107 Amdt 1","content":"## AD/SF340/107 Amdt 1","sortOrder":1},{"sectionNumber":"Fuel System - Refuel/Defuel Illuminated ","sectionType":"part","heading":"Fuel System - Refuel/Defuel Illuminated Placard","content":"## Fuel System - Refuel/Defuel Illuminated Placard","sortOrder":2},{"sectionNumber":"10/2008","sectionType":"part","heading":"10/2008","content":"## 10/2008","sortOrder":3}],"analysis":{"flash_summary_failed":{"failed":true,"reason":"A positive credit balance is required for all requests, including BYOK, so fallback providers remain available.
