AD NUMBER: 2019-24-16

PRODUCT: Certain Embraer S.A. Model ERJ 190-100 STD, -100 LR, -100 IGW, and -100 ECJ airplanes; and Model ERJ 190-200 STD, -200 LR, and -200 IGW airplanes.

ACTION: Final rule

SUMMARY: The FAA is superseding Airworthiness Directive (AD) 2017-16-08, which applied to certain Embraer S.A. Model ERJ 190-100 STD, -100 LR, -100 IGW, and -100 ECJ airplanes; and Model ERJ 190-200 STD, -200 LR, and -200 IGW airplanes. AD 2017-16-08 required revising the existing maintenance or inspection program, as applicable, to incorporate more restrictive airworthiness limitations.

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

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

DATES: This AD is effective February 3, 2020.

COST: The FAA estimates that this AD affects 107 airplanes of U.S. registry. Operators may incur the following costs in order to comply with this AD:

The actions that are required by AD 2017-16-08 and retained in this final rule take about 1 workhour per product, at an average labor rate of $85 per work hour. Required parts cost about $0 per product. Based on these figures, the estimated cost of the actions that were required by AD 2017-16- 08 is $85 per product.

The FAA has determined that revising the existing maintenance or inspection program takes an average of 90 work-hours per operator, although the agency 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 to be $7,650 (90 work-hours x $85 per work-hour).
