AD NUMBER: 2018-07-21

PRODUCT: All Fokker Services B.V. Model F28 Mark 0100 airplanes.

ACTION: Final Rule.

SUMMARY: The FAA is superseding Airworthiness Directive (AD) 2005-12-16, which applied to the aircraft listed above.

AD 2005-12-16 required an inspection to determine the part number of the passenger service unit (PSU) panels for the PSU modification status, and corrective actions if applicable.

This new AD requires an inspection of the PSU panels and the PSU panel/airplane interface connectors for discrepancies, and corrective actions if necessary.

This AD also removes airplanes from the applicability. This AD was prompted by reports of smoke in the passenger compartment during ground operations and in-flight, and a determination that the modification actions required by AD 2005-12-16 might not have been implemented correctly.

DATES: This AD is May 21, 2018.

COST: The FAA estimates that this AD affects 8 airplanes of U.S. registry.

The actions required by AD 2005-12-16, and retained in this AD take about 5 work-hours per product, at an average labor rate of $85 per work-hour. Required parts cost about $6 per product. Based on these figures, the estimated cost of the actions that are required by AD 2005-12-16 is $431 per product.

The FAA also estimate that it would take about 13 work-hours per product to comply with the basic requirements of this AD. The average labor rate is $85 per work-hour. Based on these figures, the estimate the cost of this AD on U.S. operators to be $8,840, or $1,105 per product.
