Unsafe Condition
Metal fatigue failure of the flap drive link assembly (P/N 5644642 or 5751152) could cause loss of airplane control in a critical flight regime.
AI-generated summary from the source AD text. Verify against the official source before acting.
Required Actions
Inspect for fatigue cracking of the flap drive link assembly in accordance with SB A27-269 Figure 2. Repeat inspections at intervals not exceeding 750 landings if no cracks found. If cracks are within blend limits, rework per Figure 3 and repeat inspections every 300 landings. If cracks exceed limits, replace with new part per Figure 4.
AI-generated summary from the source AD text. Verify against the official source before acting.
Compliance Time
Prior to the accumulation of 6,250 landings on the inboard flap drive link assembly or within the next 375 landings after the effective date (May 25, 1988), whichever occurs later, unless already accomplished within the last 375 landings.
