From FAA SDR — directional buying signal, not a failure rate

Part #	Description	ATA	Propensity	SDRs	Confidence
CC670340941S	FLOOR SUPPORT	53	98%*	50	high
SH67036600	DOOR FRAME	52	96%*	48	high

* 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.
