2) List of tasks for OJT

The minimum list of tasks should be selected from the table below according to the following procedures and criteria:

(i)Filter the ATA chapters (or sub-chapters, when required) applicable to the specific aircraft type (add others if they are missing).

(ii)Identify relevant and significant tasks for each required category of INS, FOT, SGH, R/I, MEL and TS.

(iii)Retain the required percentage for each task category, and throughout ATA chapters, as much as relevant to the particular aircraft type. The selection of tasks should give precedence to tasks which are critical and complex in terms of: difficulty to execute; interpretation of the maintenance procedures / work instructions; specific tools and equipment; coordination among maintenance staff (teamwork); human factors (accessibility, human–machine interface (HMI), etc.); safety impact on the aircraft and the crew. Removal and installation tasks include the final confirmation test, if required. Credit may be given for similar tasks between ATA systems (e.g. pneumatic valves in ATA 21, 30 and 36), but this should be kept to a minimum. Some tasks may be performed on another aircraft type as long as both the system and the task are similar. The following table provides an acceptable method of selection of OJT tasks for B1 and B2 AML categories, per ATA chapter or sub-chapters, as required by point 6.2(e) of Appendix III to Annex III.

Note: For ATA Chapter 5, select at least one task from category (a), two tasks from category (b), and three tasks from category (c):

(a)Perform and/or assist in performing a scheduled maintenance check: accomplishment of 100-hour check (general aviation (GA) aircraft); accomplishment of a ‘daily’ or ‘weekly’, ‘service’, ‘transit’ or equivalent check; active participation in a scheduled check, e.g.: ‘A-Check’, ‘B-Check’, ‘C-Check’ or the equivalent of a base maintenance check.

(b)Review the aircraft maintenance log for correct completion: closure of MEL/CDL items; dent and buckle chart review, including inspections on fuselage and skin damages assessment in accordance with the SRM; fuel or oil leakage tests.

(c)Perform unscheduled inspection following: hard landing; overweight taxiing; bird/hail strike; aborted take-off; high-energy stop; wheel-bearing failure; exceedance of max NLG steering angle; landing gear shimmy/vibrations; lightning strike / HIRF; tail strike; winglet strike; severe turbulence / extreme high winds; airframe vibrations; ice/snow conditions; flight control overspeed down; hot-air duct rupture; relief pressure panels open; mercury spillage; galley spill; hydraulic fluid reaction with titanium; cabin overpressure; exceedance of fuel imbalance; smoke/fumes in the cabin; abnormal doors operations; ferry flight maintenance; others.
