Narrative:

Maintenance planning issued a task card to replace the right-hand (rh) engine upper transcowl (translating sleeve cowl) locking actuator. Amt mr. X complied with installation per our task card engineering order (eo). After completion of thrust reverser (T/right) locking actuator; inspector verified installation. Everything looked installed correctly. While performing verification of rod end actuator; looked up at actuator pin and everything looked correctly installed. Performed operational check. Thrust reverser moved back and forth normally several times. Verified no leaks. This event occurred due to minimal clearance of thrust reverser; to verify actuator rod end installation. Another out-station verified the problem; rectified the situation; no damage occurred. Aircraft returned to service. Suggest better lighting environment to verify correct installation.

Title: Two Line Mechanics report on their involvement with replacing the right engine upper translating sleeve cowl locking actuator on a CRJ-900 aircraft. The right engine would not spool-up on landing on the next flight; when engine lever was moved to reverse thrust.
