Airframe Airworthiness Directives (AD) Watchlist

Mandates visual and tactile inspection of upper guide track fittings, hinge fittings, and four retention pins to prevent rapid mid-flight decompression.

Operating limitation restricting engine anti-ice system use in dry air to prevent overheating of composite engine inlet cowlings and potential structural failure.

Accelerated ultrasonic and eddy current inspection of powdered metal high-pressure turbine disks and compressor hubs manufactured with microscopic contaminant inclusions.

Mandatory reinforcement of underfloor insulation and fire protection surrounding the permanently integrated Rear Centre Tank to protect against crash survivability fire risk.

Requires repetitive operational checks and power cycles to avoid potential un-commanded reset of Common Core System (CCS) and transient blanking of primary flight displays.

Inspection of Halon discharge pipe clamping brackets in the lower cargo hold to eliminate chafing risk against adjacent high-voltage electrical harnesses.

Redesigned titanium thrust reverser inner cowls and containment shields following Pratt & Whitney PW4000 fan blade separation events.

Repetitive non-destructive ultrasonic testing (NDT) of wing rear spar joints and rib feet to detect stress corrosion micro-cracking following prolonged desert storage.

Mandates repetitive ultrasonic and eddy current inspections of titanium fan blade dovetail roots to detect subsurface fatigue cracks before fan blade separation.

Detection of internal spring binding in the emergency RAT ejection mechanism during ground deployment testing, risking loss of emergency hydraulic power.

Inspection and re-rigging of cargo door proximity sensors and locking cams to ensure positive cockpit indication of full latch engagement.

Software update and mechanical inspection to prevent rotor blade rubbing against stator seals in the low-pressure turbine during rapid high-altitude thrust transitions.
