Models named: F.28 Mark 0070, 0100. Read the applicability below — it usually turns on serial or part numbers too.

Applicability*9

This AD applies to Fokker Services B.V. Model F.28 Mark 0070 and 0100 airplanes, certificated in any category, all serial numbers.

Compliance

You are responsible for having the actions required by this AD performed within the compliance times specified, unless the actions have already been done.

Required actions

Within 3 months after the effective date of this AD, revise the Abnormal Procedures—Hydraulics section of the Fokker F.28 AFM by incorporating the information specified in Fokker Manual Change Notification—Operational Documentation (MCNO) MCNO-F100-057, dated December 17, 2010, into the Abnormal Procedures—Hydraulics section of the AFM. Note 1 to paragraph (g) of this AD: The actions required by paragraph (g) of this AD may be done by inserting a copy of Fokker MCNO MCNO-F100-057, dated December 17, 2010, into the Abnormal Procedures—Hydraulics section of the Fokker F.28 AFM. When Fokker MCNO MCNO-F100-057, dated December 17, 2010, has been included in the general revisions of the AFM, the general revisions may be inserted in the AFM, provided the relevant information in the general revision is identical to that in Fokker MCNO MCNO-F100-057, dated December 17, 2010, and that MCNO may be removed.

Unsafe condition

This AD was prompted by an in-flight failure of the hydraulic control panel, which resulted in the absence of pressure and quantity indication of the hydraulic system and accompanying alerts for “hydraulic system 1 low quantity” and “hydraulic system 2 low quantity.” We are issuing this AD to prevent loss of control of the airplane due to incorrect hydraulic system failure information being provided to the flightcrew, followed by application of inappropriate procedures.

Affected ADs

None.
