Airworthiness Directive · Amendment 39-19078 · Navigation
Airbus Airplanes
This AD applies to Airbus Model A300 B2-1A, B2-1C, B2K-3C, B2-203, B4-2C, B4-103, and B4-203 airplanes, certificated in any category, all manufacturer serial numbers.
We are adopting a new airworthiness directive (AD) for all Airbus Model A300 series airplanes. This AD was prompted by a report of reduction of the de-icing performance of the pitot probe over time that could remain hidden to the flight crew. This AD requires repetitive detailed inspections of the pitot probe heater insulation resistance, and replacement of the pitot probe heater if necessary. We are issuing this AD to address the unsafe condition on these products.
For the purpose of this AD, affected pitot probes are the First Officer's Pitot Probe 40DA, Captain's Pitot Probe 41DA, and Standby Pitot Probe 42DA.
At the time specified in paragraph (h)(1) or (h)(2) of this AD, whichever occurs later, do a detailed inspection of the pitot probe heater insulation resistance on each affected pitot probe, in accordance with the Accomplishment Instructions of Airbus Service Bulletin A300-34-0185, Revision 00, dated August 29, 2016. Repeat the inspection thereafter at intervals not to exceed 24 months.
(1) Within 24 months since the last detailed inspection of the pitot probe heater insulation resistance, as specified in Airbus A300 Aircraft Maintenance Manual (AMM), Task 30-31-00, Insulation Test of Pitot Heater Resistance.
(2) Within 6 months after the effective date of this AD.
If, during any detailed inspection as required by paragraph (h) of this AD, any pitot probe fails the test, as specified in the Accomplishment Instructions of Airbus Service Bulletin A300-34-0185, Revision 00, dated August 29, 2016, before further flight, replace the affected pitot probe with a serviceable (new or inspected as required by this AD) pitot probe, in accordance with the Accomplishment Instructions of Airbus Service Bulletin A300-34-0185, Revision 00, dated August 29, 2016. Replacement of pitot probes, as required by this paragraph, does not constitute terminating action for the repetitive inspections required by paragraph (h) of this AD.
At the applicable times required by paragraph (j)(1) or (j)(2) of this AD: Submit a report of the findings (both positive and negative) of each inspection required by paragraph (h) of this AD, as specified in the Accomplishment Instructions of Airbus Service Bulletin A300-34-0185, Revision 00, dated August 29, 2016, to Airbus Service Bulletin Reporting Online Application on Airbus World (https://w3.airbus.com/).
(1) For inspections done before the effective date of this AD: Within 30 days after the effective date of this AD.
(2) For inspections done on or after the effective date of this AD: Within 30 days after accomplishing each inspection required by paragraph (h) 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.
