REGULATORY TEXT:  
47-20-01 BELLANCA (AERONCA): Amendment 39-3712. (Was Service Note 1 of AD-759-3 and Service Note 1 of AD-761-2.) Applies to Bellanca (Aeronca) Model 7AC, 7BCM, and 11AC aircraft, equipped with metal gascolator bowls, certificated in all categories.

Compliance required as indicated below.

1. If the aircraft is equipped with a metal gascolator bowl that does not have a built in quick-drain arrangement, accomplish the following each 25 hours of engine operation:

(a) Slowly rock the wings of the aircraft in accordance with Champion (Aeronca) supplement to "Service Helps and Hints", Nos. 15 and 18, reissued July 1, 1964, so that water lying in the fuel tank can settle into the gascolator bowl.

(b) Remove the gascolator bowl and completely clean the bowl and the strainer screen to remove accumulations of water and foreign matter.

NOTE: If operating conditions are such that large quantities of water are found during these inspections, the gascolator bowl should be removed more frequently and the carburetor bowl should also be drained periodically.

2. If the aircraft is equipped with a metal gascolator bowl that does have a built in quick-drain arrangement, at each annual inspection remove the gascolator bowl and completely clean the bowl and the strainer screen to remove accumulations of water and foreign matter.

NOTE: Quick-drain shall be used during each pre-flight inspection.

Bellanca (Champion)(Aeronca) "Service Helps and Hints", No. 15, reissued July 1, 1964; No. 18, reissued March 15, 1962; and the supplement to these bulletins, reissued July 1, 1964, also pertain to this subject.

This Amendment 39-3712 becomes effective March 18, 1980.
