R If a parameter is applicable, you must highlight all the figures on
R the line for the parameter.
R When all the lines for the aplicable parameters are highlighted, add
R all the highlighted figures in each vertical column.
R Record the total on the TOTAL line.
R The highest totals show the most probable causes.

R A. Corrective Actions Types
R NOTE : To make sure that the trouble is fully covered, do the corrective
____ R actions related to the two highest totals. R E.g. if FLIGHT CONTROLS and EXTERNAL DISTURBANCE have the highest R totals, the corrective actions will be TYPE A and TYPE E. R If BRAKING SYSTEM and ENGINES have the highest totals, the R corrective actions will be TYPE C and TYPE D.
R (1) Type A

R (a) The cause of the lateral jerk at take-off is a rudder sharp
R deflection.
R - do the procedure (Ref. TASK 27-26-00-810-801).

R (2) Type B

R (a) The cause of the lateral jerk at take-off is a sudden nose wheel
R deflection.
R - do the procedure (Ref. TASK 32-51-00-810-825) and (Ref. TASK
R 32-51-00-810-836).

R (3) Type C

R (a) The cause of the lateral jerk at take-off is sudden differential
R braking.
R - do the procedure (Ref. TASK 32-42-00-810-925)

R (4) Type D: 2 possibilities

R (a) Engine differential or slow acceleration.
R - do the procedure for CFM engines (Ref. TASK 71-00-00-810-807),
R (Ref. TASK 73-00-00-810-866) and (Ref. TASK 77-00-00-810-852).
R - do the procedures for IAE engines (Ref. TASK 73-00-00-810-880),
R (Ref. TASK 73-00-00-810-881), (Ref. TASK 73-00-00-810-882) and
R (Ref. TASK 73-00-00-810-883).

R (b) Engine N1/EPR mismatch or thrust asymmetry.
R - do the procedure for CFM engines (Ref. TASK 77-00-00-810-860)
R - do the procedures for IAE engines (Ref. TASK 73-00-00-810-884),
R (Ref. TASK 73-00-00-810-885), (Ref. TASK 73-00-00-810-890) and
R (Ref. TASK 73-00-00-810-891).

R (a) The cause of the lateral jerk at take-off is an external
R disturbance.
R - no maintenance action is necessary.
