## The airworthiness directive

79-04-04 TAYLORCRAFT AVIATION CORPORATION: Amendment 39-3416. Applies to Taylorcraft Model F-19 aircraft, serial numbers 001 through 112, 115 through 130, and 132.

Compliance is required as indicated. To prevent fire hazard in the charging circuit, accomplish the following:

This AD must be accomplished prior to next 50 hours time in service after the effective date of this AD or by July 1, 1979, whichever occurs first.

Remove the 12 gauge wire, identified as P/N -10, which connects the starter solenoid "battery terminal" with the master switch. Use Mil Spec MilC7078 or equivalent 8 gauge shielded wire, to fabricate a cable in the same manner as the 8 gauge cable from the alternator to the ammeter. Use appropriate wire terminals. Attach this cable to the ignition switch terminal of the ammeter. Route this 8 gauge wire through the opening in the firewall where the 12 gauge wire previously ran and attach it to the starter solenoid "battery terminal". (See attached wiring diagram.)

This amendment becomes effective February 23, 1979.
