As presented it prescribes applicability (all Piper PA-22 models not incorporating SL 362), references specific documents for the inspection procedure (Piper SB No. 174 or FAA AD 61-6-6), and sets a recurring inspection interval (100 hours TIS or 6 months) (Applicability; Document; Compliance). The source text does not include the pre-amendment wording, so the precise nature of the change from the original AD cannot be determined from this document alone; the presence of the \"Amdt 1\" designation indicates the AD has been formally amended."},"complexity_factors":["Clear, narrow prescription: single recurring inspection requirement with a single compliance interval (Compliance).","Applicability carve-out tied to the presence of SL 362—determining whether an aeroplane \"incorporates SL 362\" requires technical record checks (Applicability).","Procedural detail is deferred to external documents (Piper SB No. 174 or FAA AD 61-6-6), so operators must obtain and follow those documents to implement the AD (Document).","Recurring compliance frequency (100 hours TIS or 6 months) creates ongoing operational scheduling and cost requirements (Compliance).","The AD text does not include acceptance criteria, corrective action steps or alternative compliance pathways—those are in referenced documents or in Part 39 processes—adding a small interpretive step for implementers (Document; Part 39 header)."],"plain_english_summary":"This AD requires owners/operators of Piper PA‑22 (Tri‑Pacer and Colt) aeroplanes not incorporating SL 362 to inspect the fuselage fabric at the windshield top attachment channel.
