AD NUMBER: 2020-04-22

PRODUCT: Certain Dassault Aviation Model FALCON 2000EX airplanes.

ACTION: Final rule

SUMMARY: The FAA is superseding Airworthiness Directive (AD) 2018-19-27 and AD 2014-16- 12, which applied to certain Dassault Aviation Model FALCON 2000EX airplanes.

AD 2018-19-27 and AD 2014-16-12 required revising the existing maintenance or inspection program, as applicable, to incorporate new maintenance requirements and airworthiness limitations.

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

This AD was prompted by the FAA's determination that new or more restrictive airworthiness limitations are necessary.

DATES: This AD is effective May 4, 2020.

COST: The FAA estimates that this AD affects 173 airplanes of U.S. registry. Operators may incur the following costs in order to comply with this AD:

The FAA estimates the total cost per operator for the retained actions from AD 2018-19-27 to be $7,650 (90 work-hours x $85 per work-hour).

The FAA has determined that the new revision of the existing maintenance or inspection program takes an average of 90 work-hours per operator, although the FAA recognizes that this number 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), the FAA has determined that a per-operator estimate is more accurate than a per-airplane estimate. Therefore, the FAA estimates the total cost per operator for the new revision to be $7,650 (90 work-hours x $85 per work-hour).
