This directive mandates specific safety work to prevent that.\n\n**Who must comply:** Anyone operating Fokker F28 aircraft in Australia. The technical details of exactly which aircraft and what work is required are found in **Fokker Service Bulletin F28/53-54** (referenced but not reproduced here).\n\n**Deadline:** The work had to be completed **before 1 January 1976** — meaning this is a historical directive that would only be relevant today for historical aircraft operations or archival purposes."},"flash_summary":{"complexity_score":3,"scope_assessment":{"changed":false,"description":"The source text provides a single, self-contained AD requiring inspection and modification per a referenced service bulletin with a set compliance date.
