AD/P68/17 superseded AD/P68/9 and mandated installation of switch 7.345-4 in accordance with SB No. 46. This latter switch proved to be electrically inadequate so in 1980 AD/P68/17 was amended to mandate removal and replacement with 7.345-1/M or an approved alternative. In 1982 Partenavia issued SB No. 55 superseding SB Nos 33 and 46 and specifying a new switch 7.2345D-1. The Italian RAI mandated SB No. 55 in AD 82-206. A review of AD/P68/17 Amdt 1 in 2008 determined that it should be amended to match the Italian AD. |\n| ----------- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |\n\n![](image.001.png)  \nJames Coyne  \nDelegate of the Civil Aviation Safety Authority\n\n17 July 2008","sortOrder":0},{"sectionNumber":"AD/P68/17 Amdt 2","sectionType":"part","heading":"AD/P68/17 Amdt 2","content":"## AD/P68/17 Amdt 2","sortOrder":1},{"sectionNumber":"Flap Actuator Switch - Inspectionand Rep","sectionType":"part","heading":"Flap Actuator Switch - Inspectionand Replacement","content":"## Flap Actuator Switch - Inspection  \nand Replacement","sortOrder":2},{"sectionNumber":"9/2008","sectionType":"part","heading":"9/2008","content":"## 9/2008","sortOrder":3}],"analysis":{"flash_summary_failed":{"failed":true,"reason":"Unauthenticated.
