AD NUMBER: 2019-03-11

PRODUCT: Certain Airbus SAS Model A350-941 and -1041 airplanes.

ACTION: Final Rule.

SUMMARY: This AD was prompted by a determination that more restrictive maintenance requirements and airworthiness limitations are necessary.

This AD requires revising the existing maintenance or inspection program, as applicable, to incorporate new or more restrictive maintenance requirements and airworthiness limitations.

DATES: This AD is effective March 29, 2019.

COST: The FAA estimates that this AD affects 11 airplanes of U.S. registry. Operators may incur the following costs in order to comply with this AD:
The FAA has determined that revising the existing maintenance or inspection program takes an average of 90 work-hours per operator, although this figure may vary from operator to operator. In the past, the FAA has estimated that this action takes 1 work-hour per airplane. Since operators incorporate maintenance or inspection program changes for their affected fleet(s), a per-operator estimate is more accurate than a per-airplane estimate. Therefore, the estimated the total cost per operator to be $7,650 (90 work-hours x $85 per work-hour).
