SUPPLEMENTARY INFORMATION:
Background The EASA, which is the Technical Agent for the Member States of the European Union, has issued EASA AD
20210002, dated January 6, 2021
EASA AD 20210002 also referred to as the Mandatory Continuing Airworthiness Information, or the MCAI, to correct an unsafe condition for all Airbus SAS Model A318 series airplanes; Model A319 series airplanes;
Model A320211, 212, 214, 215, 216, 231, 232, 233, 251N, 252N, 253N, 271N, 272N and 273N
airplanes; and Model A321 series airplanes. Model A320215 airplanes are not certified by the FAA and are not included on the U.S. type certificate data sheet; this AD therefore does not include those airplanes in the applicability.
This AD was prompted by a report that following accomplishment of tap tests on rudders that were modified using the procedures in previously issued service information Airbus Service Bulletin A320551052 dated July 28, 2017, Revision 01, dated January 28, 2015, and Revision 02, dated July 11, 2019, or Airbus Service Bulletin A320551059, dated March 8, 2018, disbonding of the rudder was found close to the lightning protection plate. Investigation results determined that those procedures may lead to inadequate curing of the affected part after modification. The FAA is issuing this AD to address disbonding of the rudder, which could result in reduced structural integrity of the rudder, and consequent reduced controllability of the airplane.
Related Service Information Under 1
CFR Part 51
EASA AD 20210002 describes procedures for a one-time general visual inspection and a special detailed inspection woodpecker or tap test of the leftand right-hand rudder side shells for defects including bulging, waviness, and disbonding and applicable corrective actions. The corrective actions include accomplishing a special detailed inspection of any affected part with defects and a temporary and eventual permanent repair of the defects. EASA
AD 20210002 also prohibits modification of a rudder using the procedures in previously issued service information. This material is reasonably
