Airworthiness Directive · Amendment 39-15001 · Airbus Model A300 B4-600, B4-600R, and F4-600R Series Airplanes, and Model C4-605R Variant F Airplanes (Collectively Called A300-600 Series Airplanes)
Airbus Model A300 B4-600, B4-600R, and F4-600R Series Airplanes, and Model C4-605R Variant F Airplanes (Collectively Called A300-600 Series Airplanes)
This AD applies to Airbus Model A300 B4-600, B4-600R, and F4-600R series airplanes, and Model C4-605R Variant F airplanes (collectively called A300-600 series airplanes); certificated in any category; as identified in Airbus Service Bulletin A300-27-6057, dated May 17, 2005.
The FAA is adopting a new airworthiness directive (AD) for certain Airbus Model A300-600 airplanes. This AD requires an inspection to determine if certain spoiler actuators having certain part numbers are installed, and eventual replacement of all affected actuators. This AD results from failure of a distribution block, which was detected during fatigue qualification tests of certain spoiler actuators. We are issuing this AD to prevent failure of the distribution block, which could result in leakage of the hydraulic fluid that supplies those actuators. This failure could cause failure of one of the three spoiler actuators and the associated hydraulic circuits, which could result in loss of those hydraulic circuits and consequent reduced controllability of the airplane.
You are responsible for having the actions required by this AD performed within the compliance times specified, unless the actions have already been done.
Within 700 flight hours after the effective date of this AD: Inspect to determine if a spoiler actuator with part number P376A0002-04 or P376A0002-08 is installed, by doing all the applicable actions in accordance with the Accomplishment Instructions of Airbus Service Bulletin A300-27-6057, excluding Appendix 01, dated May 17, 2005. If the part number cannot be found on the spoiler actuator: Operators may inspect the distribution block on the spoiler actuator to determine if part number P376A0089-00 is installed (distribution blocks having this part number are only on actuators with the affected part numbers).
(1) If no actuator with any part number identified in paragraph (f) of this AD is installed, no further action is required by this paragraph.
(2) If any actuator with any part number identified in paragraph (f) of this AD is installed and the three associated hydraulic circuits are affected (at least one actuator supplied by the yellow circuit and at least one actuator supplied by the blue circuit and at least one actuator supplied by the green circuit): Within 100 flight hours after accomplishing the inspection required by paragraph (f) of this AD, replace all affected actuators on one of the hydraulic circuits with new actuators in accordance with the service bulletin. Within 12 months after accomplishing that replacement, replace all the remaining affected actuators with new actuators in accordance with the service bulletin.
(3) If any actuator with any part number identified in paragraph (f) of this AD is installed and one or two of the associated hydraulic circuits are affected: Within 12 months after accomplishing the inspection required by paragraph (f) of this AD, replace all affected actuators with new actuators in accordance with the service bulletin.
After the effective date of this AD, no spoiler actuator with part number P376A0002-04 or P376A0002-08 may be installed on any airplane.
Although Airbus Service Bulletin A300-27-6057, excluding Appendix 01, dated May 17, 2005, specifies to submit an inspection report to the manufacturer, this AD does not include that requirement.
The aircraft, engines and makers this AD names, by the model designations in its text. A model listed here may still be outside the AD's serial ranges.
