AD/CESSNA 177/26

Amdt 1

Vented Fuel Caps 8/80

Applicability: Model 177 with S/Nos. 661, 17700001 to 17701471 and 17701473 to 17701597. Requirement: Install vented fuel cap(s) in accordance with Cessna SL No. SE77-6.

Note 1: FAA AD 79-10-14, Amendment 39-3475 refers.

Note 2: 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.
