SUPPLEMENTARY INFORMATION:  

REGULATORY TEXT:  
77-07-06 BEECH: Amendment 39-2863. Applies to Models C90 (Serial Numbers LJ- 640 thru LJ-716), and E90 (Serial Numbers LW-120 thru LW-220, LW-222 and LW-223) airplanes.

To assure adequate clearance between the left hand rudder cable and the electrical components on the relay panel located under the left hand cockpit floorboard, accomplish the following:

A) Prior to further flight inspect the left hand rudder control cable under the left hand cockpit floorboard in accordance with Steps 1 through 4 of Beechcraft Service Instructions 0896, or later approved revisions, to determine that at least 3/4 inch clearance exists between the rudder control cable and all electrical components located on the relay panel.

B) If the inspection required by Paragraph A shows that the clearance is less than 3/8 inch, prior to further flight:

1. If possible, relocate the relay panel to provide at least 3/4 inch clearance, or if the relay panel cannot be relocated to provide at least 3/4 inch clearance, modify the panel in accordance with Steps 6 through 13 of Beechcraft Service Instructions 0896, or later approved revisions, and

2. Inspect the rudder cable to determine if it has been damaged by coming in contact with the electrical components. If the cable has been damaged, install a new cable, Beech P/N 50-524438-17, or an equivalent cable fabricated in accordance with acceptable FAA standards (AC 43.13-1A).

C) If the inspection required by Paragraph A shows that the clearance is between 3/8 and 3/4 inches, within 25 hours' time in service after the effective date of this AD, accomplish the requirements of Paragraphs B(1) and B(2).

D) If the inspection required by Paragraph A shows that the clearance is 3/4 inch or more, make an entry in the aircraft's maintenance records indicating that this AD has been accomplished and the airplane may be returned to service.

E) Airplanes may be flown in accordance with FAR 21.197 to a location where the needed electrical system modification or rudder cable replacement required by this AD may be accomplished. Prior to authorizing a flight under FAR 21.197, the FAA District Office involved should contact the Chief, Engineering and Manufacturing Branch, FAA, Central Region, for appropriate operating limitations.

F) Any equivalent method of compliance with this AD must be approved by the Chief, Engineering and Manufacturing Branch, FAA, Central Region.

This amendment becomes effective April 11, 1977, to all persons except those to whom it has already been made effective by air mail letter from the Federal Aviation Administration dated March 14, 1977.
