From FAA SDR — directional buying signal, not a failure rate
* Structural ATA chapters use FAA K-code change rate. Verb-based propensity is suppressed there because "REPAIRED" in the SDR text usually refers to the airframe being repaired around the part.

Directives linked to this airframe family in the FAA / EASA regulatory corpus we have processed — not a complete historical AD list. An AD is a compliance requirement that drives scheduled work (inspections, replacements, modifications) across the fleet; inspection directives are not replacement directives, and none of this is a prediction that any part will fail.
