Note: Installation of a placard is not an acceptable alternative to installation of vented fuel caps.
Compliance: Within 100 hours time in service after 31 August 1979 or before 1 January 1980 whichever is the later.
Background: To guard against the possibility of either an obstructed primary vent or sticking of the fuel tank vent valve it has been found necessary to provide secondary venting in the form of vented fuel caps. Due to some misinterpretation of this Directive a NOTE has now been added to disallow the fitting of a placard.
