Airworthiness Directive · Amendment 39-18559 · Navigation
Airbus Airplanes
This AD applies to the airplanes identified in paragraphs (c)(1), (c)(2), (c)(3), and (c)(4) of this AD, certificated in any category, all manufacturer serial numbers.
(1) Airbus Model A318-111, -112, -121, and -122 airplanes.
(2) Airbus Model A319-111, -112, -113, -114, -115, -131, -132, and -133 airplanes.
(3) Airbus Model A320-211, -212, -214, -231, -232, and -233 airplanes.
(4) Airbus Model A321-111, -112, -131, -211, -212, -213, -231, and -232 airplanes.
We are superseding Airworthiness Directive (AD) 2016-09-07 for all Airbus Model A318, A319, A320, and A321 series airplanes. AD 2016- 09-07 required replacing certain pitot probes on the captain, first officer, and standby sides. This new AD retains those requirements, but with a revised compliance time. Since we issued AD 2016-09-07, we received additional reports of airspeed indication discrepancies during flight at high altitudes in inclement weather. We are issuing this AD to prevent airspeed indication discrepancies caused by accumulation of ice crystals during inclement weather, which, depending on the prevailing altitude, could lead to reduced controllability of the airplane.
On or before November 12, 2016: Replace any Thales pitot probe having part number (P/N) C16195AA or P/N C16195BA with a Goodrich pitot probe having P/N 0851HL, in accordance with the Accomplishment Instructions of Airbus Service Bulletin A320-34-1170, Revision 30, dated June 18, 2015. The replacement in this paragraph terminates the requirements of paragraph (f) of AD 2004-03-33 for that airplane only.
(1) Replacement of the pitot probes in accordance with the Accomplishment Instructions of both Airbus Service Bulletin A320-34-1456, Revision 01, dated May 15, 2012 (pitot probes on the captain and standby sides); and Airbus Service Bulletin A320-34-1463, Revision 01, dated May 15, 2012 (pitot probes on the first officer side); is an acceptable method of compliance for the requirements of paragraph (g) of this AD.
(2) Airplanes on which Airbus Modification 25578 was embodied in production, except for post-modification 25578 airplanes on which Airbus Modification 155737 (installation of Thales pitot probes) was also embodied in production, are compliant with the requirements of paragraph (g) of this AD, provided it can be conclusively determined that no Thales pitot probe having P/N C16195AA, P/N C16195BA, or P/N 50620-10 has been installed since the date of issuance of the original certificate of airworthiness or the date of issuance of the original export certificate of airworthiness. Post-modification-25578 airplanes on which Airbus Modification 155737 (installation of Thales pitot probes) was also embodied in production must be in compliance with the requirements of paragraph (g) 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.
