On the Job Training (OJT) - Line Maintenance

           Reference CAR D2E-E8 
4.17 On The Job Practical Training 
4.17.1 For completion of the course, six months On the Job Training (OJT) shall be mandatory. These six months OJT may be given in a continuous period or may be divided into two segments of three months each. For imparting practical training on aircraft maintenance to the trainees, facilities acceptable to DGCA and as specified in Appendix V must exist.
                        OJT is knowledge obtained while participating in accomplishing the task under the direction of a qualified person or watching another demonstrate a task or activity and then accomplishing the same action under supervision until satisfactory results are obtained.
                       It is an effective method of training for subject matter and tasks that are difficult to understand if described or for which demonstration of capability is essential to correct completion.                Practical skills may also be taught using OJT.
                      To make this method of training most effective, the process for providing the information should be standardized by using, for a particular task, the approved data from the article’s maintenance manual, and the referenced tools and/or equipment.
                      The process should document that the employee demonstrated the ability to accomplish the skill or task properly on the requisite OJT record.
                     The same process can then be used to train other employees to the same task, activity, or skill. Even with a very capable instructor, the AMO should ensure any OJT is well structured by establishing that the same key elements are included each time.
