AD 2016-10-15 Airworthiness Directives; Fokker Services B.V. Airplanes
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, equipped with a center wing tank.
Compliance
Comply with this AD within the compliance times specified, unless already done.
Required actions
Within 24 months after the effective date of this AD: Modify the wiring of the maximum level sensors of the center wing fuel tank, as specified in paragraph (g)(1) or (g)(2) of this AD, as applicable. Before further flight after accomplishing the modification, do all applicable tests and corrective actions, in accordance with Part 5 of the Accomplishment Instructions of the service information identified in paragraph (j) of this AD. (1) For post-SBF100-28-073 configuration airplanes: Do the modification in accordance with Part 1 or Part 3, as applicable, of the Accomplishment Instructions of the service information identified in paragraph (j) of this AD. (2) For pre-SBF100-28-073 configuration airplanes: Do the modification in accordance with Part 2 or Part 4, as applicable, of the Accomplishment Instructions of the service information identified in paragraph (j) of this AD.
Unsafe condition
This AD was prompted by a design review which revealed that a wiring failure, external to the center wing fuel tank, could cause a hot short circuit to a maximum level sensor wire, and result in excessive heating of the maximum level sensor element. We are issuing this AD to prevent the potential of ignition sources inside fuel tanks, which, in combination with flammable fuel vapors, could result in fuel tank explosions and consequent loss of the airplane.
Affected ADs
None.
