General Maintenance Action
Human Factors; Aircraft; Logbook Entry; Procedure
We arrived in ZZZ airport and discovered during post flight that the emergency brake and gear pneumatic vent lines were dripping hydraulic fluid onto the ground. The aircraft was AOG'ed. The next morning we were assigned the aircraft again as the discrepancy was cleared by technicians from ZZZ1 Service Center. The summary of the corrective action is that the lines were disconnected; vacuumed free of hydraulic fluid cleaned with alcohol and re-secured. Three flights were performed on the following day; ending our day in ZZZ2. On post flight it was discovered that the leak had returned in the gear pneumatic vent line.How it can be said that removing evidence of a discrepancy is an appropriate corrective action is ridiculous. This is an ever increasing trend at this company. Who directly is responsible in this case would be the individual who signed this off; but more importantly it appears to me to be an increasing cultural trend that is spreading from our Operator to all maintenance contractors.
A First Officer questions whether a logbook corrective action entry by Maintenance was appropriate or just ridiculous. He found the emergency brake and landing gear pneumatic vent lines dripping hydraulic fluid during a post flight walk around of their Cessna Citation X aircraft. Maintenance had disconnected; vacuumed; cleaned with alcohol; and re-secured the lines.
