Plain English Summary

2/10 complexity

Requires owners/operators of specified Cessna 150 and A150 serial-numbered aeroplanes to install vented fuel caps by following one of three listed Cessna/FAA/Bureau Veritas documents. Compliance is due within 100 hours’ time-in-service after 31 August 1979 or before 1 January 1980, whichever is later.

A placard is explicitly not an acceptable alternative. The cost and compliance burden fall to aircraft owners to add secondary venting to protect against obstructed vents or a sticking tank vent valve.

Amdt 1

Vented Fuel Caps 8/80

Applicability: Model 150 with S/Nos. 617, 628, 649, 17001 to 17999, 59001 to 59018 and 15059019 to 15077005. Model A150 with S/Nos. 15064970 and A1500001 to A1500609.

Requirement: Install vented fuel cap(s) in accordance with:

Cessna SL No. SE 77-6; or
FAA AD 79-10-14, Amendment 39-3475; or
Bureau Veritas AD 79-155-IMP(A).

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 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.
