This AD applies to Airbus SAS Model A319-131, A319-132, A319-133, A320-231, A320-232, A320-233, A321-131, A321-231, and A321-232 airplanes, certificated in any category, if modified by Bombardier Short Brothers, PLC Supplemental Type Certificate (STC) ST03076NY.
We are adopting a new airworthiness directive (AD) for certain Airbus SAS Model A319-131, A319-132, A319-133, A320-231, A320-232, A320-233, A321-131, A321-231, and A321-232 airplanes. This AD was prompted by reports of fan cowl door (FCD) losses during take-off. This AD requires modification and re-identification, or replacement, of certain FCDs, and installation of a placard in the flight deck. We are issuing this AD to address the unsafe condition on these products.
Within 18 months after the effective date of this AD: Do the modification and re-identification specified in paragraphs (g)(1) and (g)(2) of this AD.
(1) Modify each left-hand (LH) and right-hand (RH) FCD having a part number listed as “Old Part Number” in table 1 to paragraphs (g), (h), and (l) of this AD, in accordance with the Accomplishment Instructions of Bombardier Short Brothers Service Bulletin V25MFC-71-1003, dated September 28, 2016.
(2) Re-identify each modified FCD with the part number listed as “New Part Number” in table 1 to paragraphs (g), (h), and (l) of this AD, in accordance with the Accomplishment Instructions of Bombardier Short Brothers Service Bulletin V25MFC-71-1003, dated September 28, 2016.
(1) Replacement of the FCDs having a part number listed as “Old Part Number” in table 1 to paragraphs (g), (h), and (l) of this AD, with the FCDs having the corresponding part number listed as “New Part Number” in table 1 to paragraphs (g), (h), and (l) of this AD, is acceptable for compliance with the requirements of paragraph (g) of this AD.
(2) Installation on an engine of a LH and RH FCD having a part number approved after the effective date of this AD is acceptable for compliance with the requirements of paragraph (g) of this AD for that engine only, provided the conditions specified in paragraphs (h)(2)(i) and (h)(2)(ii) of this AD are met.
(i) The part number is approved using a method approved by the Manager, International Section, Transport Standards Branch, FAA; or the European Aviation Safety Agency (EASA); or Bombardier Short Brothers, PLC's EASA Design Organization Approval (DOA). If approved by the DOA, the approval must include the DOA-authorized signature.
(ii) The installation is accomplished using a method approved by the Manager, International Section, Transport Standards Branch, FAA; or EASA; or Bombardier Short Brothers, PLC's EASA DOA. If approved by the DOA, the approval must include the DOA-authorized signature.
For airplanes on which Airbus SAS modification 157718 has not been embodied in production: Within 18 months after the effective date of this AD, install a placard that specifies the FCD keys stowage location in the flight deck on the box located at the bottom of the 120VU panel, or at the bottom of the coat stowage, as applicable to airplane configuration, using a method approved by the Manager, International Section, Transport Standards Branch, FAA; or EASA; or Bombardier Short Brothers, PLC's EASA DOA. If approved by the DOA, the approval must include the DOA-authorized signature.
Flights with one or both FCD keys missing from the stowage location in the fight deck, or with the placard (that specifies the FCD keys stowage location) missing or damaged, are permitted for a period not to exceed 10 calendar days from the date of discovery.
As an option to paragraph (i) of this AD, an alternate location for the key stowage in the flight deck and installation of a placard for identification of that stowage location are permitted as specified in the operator's FAA-accepted maintenance or inspection program, provided the keys can be retrieved from that flight deck location when needed and the placard installation is done within 18 months after the effective date 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.
