Cracking, if undetected could lead to catastrophic structural failure.Amendment 1 is issued in response to a new, revised EASA AD, which retains the inspections, repair and rework requirements of UK CAA AD G-2005-0019; requires the additional accomplishment of ISB 53-182 Revision 1. This revision to the ISB adds an eddy current inspection of the frame outer flanges and door hinge bosses which have also been found to be susceptible to corrosion. |\n\n![](image.001.png)  \nDavid Villiers  \nDelegate of the Civil Aviation Safety Authority\n\n22 May 2008","sortOrder":0},{"sectionNumber":"AD/BAe 146/116 Amdt 1","sectionType":"part","heading":"AD/BAe 146/116 Amdt 1","content":"## AD/BAe 146/116 Amdt 1","sortOrder":1},{"sectionNumber":"Fuselage Door Frames","sectionType":"part","heading":"Fuselage Door Frames","content":"## Fuselage Door Frames","sortOrder":2},{"sectionNumber":"7/2008","sectionType":"part","heading":"7/2008","content":"## 7/2008","sortOrder":3}],"analysis":{"flash_summary_failed":{"failed":true,"reason":"Unauthenticated.
