## Summary

The FAA proposes to adopt a new airworthiness directive (AD) for all Fokker Model F.28 Mark 0070 and 0100 airplanes. This proposed AD would require a one-time inspection of the fuel lines located in the left and right main landing gear (MLG) bays to determine the clearance between the fuel and hydraulic lines. If necessary, this proposed AD would also require an inspection of fuel lines for chafing, replacement of a chafed fuel line with a new fuel line, and the repositioning of existing clamps and installation of additional clamps between the fuel and hydraulic lines. This proposed AD results from a fuel leak found in the left MLG bay. We are proposing this AD to detect and correct inadequate clearance between fuel and hydraulic lines in the MLG bay, which could lead to chafing of a fuel line and fuel leakage. A fuel leak near hot brakes could result in a fire in the MLG bay.
