AD NUMBER: 2012-19-04

PRODUCT: Certain Fokker Services B.V. Model F.28 Mark 0100 airplanes.
SUBJECT: Airworthiness Directive 2012-19-04
ACTION: Final Rule

SUMMARY: The FAA is superseding two existing airworthiness directives (ADs) for the products listed above. The first existing AD currently requires removing the actuator from the fuel-balance transfer-valve (FBTV) and installing a locking device on the FBTV. The second existing AD currently requires inspecting to verify that the position indicator of the FBTV is in the closed position and deactivating the fuel-balance transfer-system. This new AD requires installing an FBTV locking device.

This AD was prompted by reports that the FBTV was inadvertently reactivated after required de-activation measures were undone.

The FAA is issuing this AD to prevent fuel starvation and a consequent double-engine flameout, possibly resulting in a forced landing, damage to the airplane, and injury to occupants.

DATES: This AD becomes effective November 5, 2012.
