47-30-08  AERONCA:  (Was Mandatory Note 9 of AD-675-2 and Mandatory Note 7 of AD- 702-1.)  Applies to Models 65-CA, S-65-CA and 65-LA. 

	Compliance required not later than September 30, 1947. 

	In order to prevent the seat belt anchorage from failing during a crash landing, it has been found necessary to modify the seat installation as follows: 

	1.	If there is no need for an adjustable seat, the rear sliding lugs on each side of the seat should be bolted to the slide tube using 3/16-inch AN bolts.  Location of bolt approximately 1 1/8 inches below and 3/8 inch forward of center of seat cross tube. 

	2.	If the seat is to remain adjustable, the rear sliding lugs on the seat are to be reinforced with two 0.094 inch, 1025 steel gussets.  Weld corner gussets between fore and aft sides of seat cross tube and back face of seat slide lugs.  Gussets are "L" shaped approximately 1 inch wide, extending around bottom lip of lugs.  (Aeronca Service Memorandum M-76 dated May 15, 1947,covers this same subject.)
