Plain English Summary

3/10 complexity

This AD requires owners/operators of specific Cessna 188/A188 (listed serial ranges) to install vented wing fuel caps per Cessna Service Letter SE77‑6 within the stated time window; fitting a placard is explicitly not acceptable. It aims to provide secondary venting to reduce the risk of blocked fuel tank vents. Compliance costs (parts/labour) fall to aircraft owners/operators.

Amdt 1

Vented Fuel Caps 8/80

Applicability: Models 188 and A188 (with wing fuel tanks) with S/Nos. 653, 18800446 to 18800572 and 18800573 to 18800762.

Requirement: Install vented fuel cap(s) in accordance with Cessna SL No. SE77-6;

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

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.
