Narrative:

I accomplished the left hand and right hand 'thrust reverser sync lock-operational check' job card; all by myself. Later; after careful consideration; I understood that it was better to do a re-check even though all tests passed and operational checks were normal. Include more possible discrepancy examples that may cause the system to be erratic or inconsistent/intermittent in the job card and their corresponding fault isolation and maintenance practices references. Due to the fact that I did it all by myself; I understood that to reassure the reliability of the system; it was better to do a re-check.
