The airworthiness directive
49-30-02 CONVAIR: Applies to All Model 240 Aircraft.
Compliance required at next scheduled engine change.
Instances have been reported in which the augmenter vanes showed a tendency to bind under high temperature. To preclude the possibility of such instances in the future, the following must be accomplished on each of the four augmenter tubes:
1. Increase the I.D. of the augmenter vane shaft bushing to 0.509 plus 0.003, minus 0.0000 inch.
2. Reduce the O.D. of the augmenter vane shaft to 0.499 plus 0.000, minus 0.003 inch. (This subject is also covered by Convair-Liner Service Information Letter No. 407.)
In the event that it is desired to secure the specified clearance between the shaft and bushing by increasing the bushing I.D. only, this is an acceptable alternative. However, the 0.514 inch upper limit for the bushing I.D. should not be exceeded.
