The airworthiness directive
47-06-08 BEECH: (Was Service Note 1 of AD-757-2 and Service Note 1 of AD-2-582- 2.) Applies to AT-11 and C18S Aircraft.
Compliance required immediately and after each 100 hours of operation thereafter.
Remove the battery covers from the right and left-hand wing stubs. Inspect the starter solenoid and main buss lead wires. In the right wing these wires are numbered 4 and 5. In the left wing they are numbered 2 and 3. If these wires show signs of chafing on the cold air duct junction box or any other part of the structure they should be supported by an insulated clip to give ample clearance.
(Beech Service Bulletin No. C18-5 covers this same subject.)
