Unsafe Condition
Fatigue cracking of the bottom flanges of the longitudinal floor beams at frame 43 and fatigue cracking of the fastener holes in the longitudinal floor beams, which could result in reduced structural integrity of the airplane.
AI-generated summary from the source AD text. Verify against the official source before acting.
Required Actions
Perform a visual inspection for fatigue cracking of the longitudinal floor beams at frame 43 prior to 20,000 total flight cycles or within 1,000 flight cycles after the AD's effective date, whichever is later. Repeat inspections every 6,000 flight cycles if no cracking is found. If cracking is detected, repair before further flight. Additionally, perform a one-time eddy current inspection and modify floor beam fasteners before 32,000 flight cycles or within 1,000 flight cycles after the AD's effective date, whichever is later, which terminates the repetitive inspections.

Compliance Time
Prior to the accumulation of 20,000 total flight cycles, or within 1,000 flight cycles after the effective date of this AD, whichever occurs later (for part (a)) and prior to the accumulation of 32,000 total flight cycles, or within 1,000 flight cycles after the effective date of this AD, whichever occurs later (for part (b)).
