EVENT DESCRIPTION(CONTINUED) 6.6.2b(2). (USRE-Sl-76-07).
CAUSE DESCRIPTION (CONTINUED) cylinder. Rolling the engine with the cylinder test cocks open prior to start-ing the engine forced the water out of the cylinder. This permitted detection of the problem and prevented further damage to the engine.
This is the fifth cylinder head on this engine to be found with a crack in a time period of approximately three months. Cylinders #1 and #17 were the subject of USRE Sl-76-04 and 06. Cylinders #2 and #16 were found during the inspection con-ducted as a result of USRE Sl-76-06. Cylinders #1 and #2 are diametrically oppo-'
site of cylinders #16, #17 and #19. This can be indicative of a cylinder head heat stress which is caused by a cylinder heat imbalance or an engine overheat condition.
To ensure the reliability of this engine, the monthly performance test will be conducted on a weekly basis for a period of two months. If no additional cylinder heads are found to be cracked, it wi 11 be safe to assume the remaining heads have not been heat stressed to the point of failure. If additional headi are found to be cracked, the determination of the cause of the cracking may be brought to light depending on which head fails.
- ADDITIONAL FACTORS (CONTINUED)
Accordingly, no hazard to the safety or health of the general public existed .
