Action
Supplemental notice of proposed rulemaking (NPRM); reopening of comment period.
Summary
We are revising an earlier NPRM for the products listed above. This action revises the earlier NPRM by expanding the scope. This proposed AD results from mandatory continuing airworthiness information (MCAI) originated by an aviation authority of another country to identify and correct an unsafe condition on an aviation product. The MCAI describes the unsafe condition as: * * * * * The airworthiness limitations applicable to the Certification Maintenance Requirements (CMR) are given in Airbus A330 ALS Part 3, which is approved by the European Aviation Safety Agency (EASA). The revision 03 of Airbus A330 ALS Part 3 introduces more restrictive maintenance requirements and/or airworthiness limitations. Failure to comply with this revision constitutes an unsafe condition. * * * * * The unsafe condition is safety-significant latent failures that would, in combination with one or more other specific failures or events, result in a hazardous or catastrophic failure condition. The proposed AD would require actions that are intended to address the unsafe condition described in the MCAI.
