Vented Fuel Caps - Installation 9/88
Applicability: Model 336 with S/Nos. 336-0001 to 336-0195. Requirement: Install vented fuel cap(s) in accordance with:
1. Cessna SL No. SE 77-6; or

Compliance: Within 100 hours time in service after 31 August 1979; or Before 1 January 1980; whichever is the later.

Due to some misinterpretation of this Directive a note has now been added to disallow the fitting of a placard.
