Airworthiness Directive · Amendment 39-13850 · Airbus Model A310 Series Airplanes; and Model A300 B4-600, B4-600R, and F4-600R Series Airplanes; and Model C4-605R Variant F Airplanes (Collectively Called A300-600)
Airbus Model A310 Series Airplanes; and Model A300 B4-600, B4-600R, and F4-600R Series Airplanes; and Model C4-605R Variant F Airplanes (Collectively Called A300-600)
This AD applies to Airbus Model A310 series airplanes; and Model A300 B4-600, B4-600R, and F4-600R series airplanes; and Model C4-605R Variant F airplanes (collectively called A300-600); certificated in any category; as listed in Airbus Service Bulletin A300-29-6050, Revision 02, dated April 16, 2003; or A310-29-2088, Revision 01, dated February 3, 2003.
The FAA is superseding an existing airworthiness directive (AD), which applies to certain Airbus Model A310 series airplanes; and Model A300 B4-600, B4-600R, and F4-600R series airplanes; and Model C4- 605R Variant F airplanes (collectively called A300-600). That AD currently requires modifying the ram air turbine (RAT) by replacing the ejection jack. This new AD requires a one-time inspection of the RAT ejection jack to determine the part number, and further investigative and corrective actions if necessary. This AD is prompted by the discovery of a rupture in the housing of one of the RAT ejection jacks installed as specified in the existing AD. We are issuing this AD to prevent rupture of the housing of the RAT ejection jack due to overpressure in the jack caused by overfilling the hydraulic fluid, and consequent failure of the RAT ejection jack. Failure of the ejection jack could result in a lack of hydraulic pressure or electrical power in an emergency.
You are responsible for having the actions required by this AD performed within the compliance times specified, unless the actions have already been done.
For airplanes on which Airbus Modification 12259 has not been accomplished: Within 34 months after August 6, 2001 (the effective date of AD 2001-13-16, amendment 39-12297), modify the RAT per Airbus Service Bulletin A310-29-2086, Revision 01 (for Model A310 series airplanes), or A300-29-6048, Revision 01 (for Model A300 B4-600, B4-600R, and F4-600R series airplanes; and Model C4-605R Variant F airplanes (collectively called A300-600)), both dated July 12, 2000, as applicable.
Note 1: Modification of the RAT accomplished prior to August 6, 2001, in accordance with Airbus Service Bulletin A310-29-2086 or A300-29-6048, both dated April 6, 2000, as applicable, is considered acceptable for compliance with the action specified in paragraph (f) of this AD.
As of August 6, 2001, no person may install on any airplane an ejection jack, part number 730820, unless it has been modified per paragraph (f) of this AD.
Note 2: Airbus Service Bulletin A310-29-2086 and A300-29-6048, both Revision 01, refer to Hamilton Sundstrand Service Bulletin No. ERPS03/04EJ-29-1, as an additional source of service information for accomplishment of the modification of the RAT and testing of the modified RAT.
Within 2,500 flight hours after the effective date of this AD: Inspect the RAT ejection jack to determine the part number (P/N), in accordance with the Accomplishment Instructions of the applicable Airbus service bulletin listed in Table 1 of this AD. If the P/N can be determined and is neither 772652 nor 772654, no further action is required by this paragraph.

Note 3: Airbus Service Bulletins A300-29-6050 and A310-29-2088 refer to Hamilton Sundstrand Service Bulletin ERPS03/04EJ-29-2, dated May 8, 2002, as an additional source of service information for identifying subject RAT ejection jacks and performing the applicable related investigative and corrective actions.
(i) If the P/N on the RAT ejection jack is either 772652 or 772654, or if the P/N cannot be determined: Before further flight, accomplish all applicable related investigative and corrective actions in accordance with the Accomplishment Instructions of the applicable Airbus service bulletin listed in Table 1 of this AD.
Inspections and related investigative and corrective actions done before the effective date of this AD in accordance with Airbus Service Bulletin A300-29-6050 (for Model A300 B4-600, B4-600R, and F4-600R series airplanes; and Model C4-605R Variant F airplanes (collectively called A300-600)) or A310-29-2088 (for Model A310 series airplanes), both dated July 23, 2002, as applicable, are acceptable for compliance with the corresponding actions required by paragraphs (h) and (i) of this AD.
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.
