The modification must follow instructions in **Pitts Service Bulletin No. 5 and its Supplement No. 1**.\n\n**Who it affects:** Anyone who owns, operates, or maintains a Pitts S-2A aircraft with serial numbers between 2001 and 2025.\n\n**Why it matters:** The aileron inter-connect tube is critical for safe flight control. This AD addresses a known safety defect that could affect the aircraft's ability to roll or manoeuvre safely. The deadline for compliance was **before 30 September 1973**.\n\n**Key point:** This is a **historical directive** from 1973. If you own one of these aircraft today, this modification should have been completed decades ago, but maintenance records must show it was done."},"flash_summary":{"complexity_score":2,"scope_assessment":{"changed":false,"description":"The directive as presented applies only to Pitts S-2A aircraft with serial numbers 2001–2025 and requires a modification per Pitts SB No. 5, Supplement No. 1 to be completed before 30 September 1973 unless already done.
