AD NUMBER: 2020-04-12
PRODUCT: Certain Fokker Services B.V. Model F28 Mark 0070 and 0100 airplanes.
ACTION: Final rule; request for comments.
SUMMARY: The FAA is superseding Airworthiness Directives (ADs) 2012-22-05 and 2018-19-03, which applied to certain Fokker Services B.V. Model F28 Mark 0070 and 0100 airplanes.
AD 2012- 22-05 required inspecting for cracks of the pistons on the main landing gear (MLG), and replacing the affected pistons if necessary. AD 2012-22-05 also required modifying the MLG, and revising the airplane maintenance program. AD 2018-19-03 required an inspection of the MLG, and replacement if necessary.
This AD retains the requirements of AD 2012-22-05, expands the applicability, and requires a new modification or replacement of the MLG; as specified in a European Union Aviation Safety Agency (EASA) AD, which is incorporated by reference.
This AD was prompted by a determination that the required heat treatment may not have been applied to certain MLG pistons.
DATES: This AD becomes effective March 24, 2020. The FAA must receive comments on this AD by April 23, 2020.
COST: The FAA estimates that this AD affects 0 (zero) airplanes of U.S. registry. If an affected airplane is imported and
placed on the U.S. Register in the future, the FAA provide the following cost estimates to comply with this AD:
- Retained actions from AD 2012- 22-05: 24 work-hours × $85 per hour = $2,040 per airplane.
- New actions: 24 work-hours × $85 per hour = $2,040 per airplane.
