REGULATORY TEXT:  
80-22-06 UNIVERSAL OIL PRODUCTS, INC.: Amendment 39-3953. Applies to Model 900 series aircraft seats.

Compliance is required as indicated, unless already accomplished.

To prevent the possible failure of a passenger seat caused by a crack in the rear stretcher tube, accomplish the following:

1. Within the next 90 days after the effective date of this AD, visually inspect all UOP, Inc., Model 900 series aircraft seats for cracks in the rear stretcher tube.

Note. - Direct particular attention to the aisle end of the tube at the side arm attaching bolt hole.

2. Except as provided in Paragraph 3 below, replace all cracked tubes with serviceable units. Until cracked tubes are replaced, placard or otherwise mark the seat position adjacent to the cracked stretcher tube end as unusable and not to be occupied.

3. Stretcher tubes with cracks less than 1.19 inches, measured along the longitudinal axis from the centerline of the attach hole, may be repaired with clamp P/N 81672-1, in accordance with installation instructions in UOP, Inc., Service Bulletin 25-634, dated April 3, 1980. This repair is not authorized for Model 900-200B-2L seats. An equivalent method may be approved by the Chief, Engineering and Manufacturing Branch. If after installation of the clamp, the crack extends beyond the end of the clamp, the stretcher tube must be replaced.

This amendment becomes effective November 25, 1980.
