The CASA Maintenance Schedule requires inspection of empennage to fuselage attachments, and surrounding structure. This inspection no longer justifies an AD. |\n\n![](image.001.png)\n\nDavid Villiers  \nDelegate of the Civil Aviation Safety Authority\n\n20 May 2008","sortOrder":0},{"sectionNumber":"AD/PA-28/87","sectionType":"part","heading":"AD/PA-28/87","content":"## AD/PA-28/87","sortOrder":1},{"sectionNumber":"Stabilator Attach Fitting Corrosion","sectionType":"part","heading":"Stabilator Attach Fitting Corrosion","content":"## Stabilator Attach Fitting Corrosion","sortOrder":2},{"sectionNumber":"7/2008","sectionType":"part","heading":"7/2008","content":"## 7/2008","sortOrder":3}],"analysis":{"kimi_summary":{"_metrics":{"model":"kimi-k2.5","source":"moonshot-batch","completionTokens":2066},"content_quality":"ok","complexity_score":1,"scope_assessment":{"changed":true,"description":"This instrument eliminates the mandatory inspection requirements previously imposed on Piper PA-28 aircraft operators.

The Civil Aviation Safety Authority (CASA) determined that this specific inspection is now adequately covered by the standard CASA Maintenance Schedule, so the separate mandatory directive is no longer necessary.
