COMMONWEALTH OF AUSTRALIA (Civil Aviation Regulations 1998), PART 39 - 105 CIVIL AVIATION SAFETY AUTHORITY
SCHEDULE OF AIRWORTHINESS DIRECTIVES

AD/CESSNA 337/25
Amdt 1
Vented Fuel Caps - Inspection 8/80
Model 337 with S/Nos. 33700001 to 33701405. Model F337 with S/Nos. F33700001 to F3370047.
Install vented fuel cap(s) in accordance with:
1. Cessna SL No. SE77-6; or
2. FAA AD 79-10-14, Amendment 39-3475.
Installation of a placard is not an acceptable alternative to installation of vented fuel caps.
Within 100 hours time in service after 31 August 1979; OR Before 1 January 1980; whichever is the later.
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.
