Abstract :
Planning is something that needs to be prepared in the aircraft maintenance
process, planning works so that every activity in the aircraft maintenance program
can be done effectively and efficiently. One of the plans that needs to be done in the
aircraft maintenance process is the determination of turn around time (TAT). The
accuracy in the determination of the TAT greatly influences the customer's trust in
the company, so planning and evaluation analysis is needed regarding the
implementation of the ATR 72-600 PK-GAK aircraft maintenance program at PT
GMF AeroAsia Tbk.
In the process of determining turn around time (TAT), unit production
planning and control (PPC) multiplies manhours basic manufacture with a value
of 3, then taking into account the available manhours and productivity of
manpower. After TAT was determined, then an evaluation of the implementation of
the ATR 72-600 PK-GAK aircraft maintenance program at PT GMF AeroAsia Tbk.
the cause of the delay in TAT that occurs is by the fishbone method. After finding
the cause of the delay then find a solution to the cause of the delay by using the
5W1H method, and also assuming the value 3 to 3.25 as a manhours basic
manufacture multiplier with the aim of adding TAT planning value.
Planning TAT which is determined by the unit of production planning and
control (PPC) which is 13 days, is actually on the field for 14 days. The occurrence
of delays in the field due to 4 things, as for the solution of the causes of delays that
occur are improvements from the support of spare parts and material, improving
coordination between units in the implementation of the maintenance process,
speeding up the process of completion of inspection so as not to occur late finding.
Then the proposed TAT solution obtained after calculating the value 3 to 3.25 as a
multiplier for manhours basic manufacture obtained a TAT value of 14 days, in
accordance with the actual work in the field.
