AD 2015-21-05 Airworthiness Directives; Fokker Services B.V. Airplanes
Models named: F.27 Mark 200, 300, 400, 500, 600, 700. 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.27 Mark 200, 300, 400, 500, 600, and 700 airplanes, certificated in any category, all serial numbers.
Compliance
Comply with this AD within the compliance times specified, unless already done.
Required actions
At the next scheduled opening of the fuel tanks after the effective date of this AD, but no later than 84 months after the effective date of this AD: Install additional bonding provisions at the applicable locations, and install an anti-spray cover on the FSOV in both wings, using a method approved by the Manager, International Branch, ANM-116, Transport Airplane Directorate, FAA.
Unsafe condition
This AD was prompted by a design review, which revealed that no controlled bonding provisions are present on a number of critical locations inside the fuel tank or connected to the fuel tank wall; and no anti-spray cover is installed on the fuel shut-off valve (FSOV) in both wings. We are issuing this AD to prevent an ignition source in the fuel tank vapor space, which could result in a fuel tank explosion and consequent loss of the airplane.
Affected ADs
None.
