R 1. Examine the Outer Barrel to fan cowl door for mismatch.
R A. Outer Barrel to Positive step: These are the preferred
R fan cowl 70 percent measurements.
R + 0.040 in. (+ 1 mm)
R 30 percent
R +0.060 in. (+ 1.5 mm)
R At one location
R + 0.070 in. (+ 1.8 mm)
R Negative step:
R 70 percent
R -0.060 in. (-1.5 mm)
R 30 percent
R -0.075 in. (-1.9 mm)
R Between positive 0.040 If the mismatch is more
R in. (1 mm) and positive than positive maximum
R 0.060 in. (1.5 mm) or serviceable limit, measure
R negative 0.060 in. (1.5 the fan cowls at 10 equal

R measurements and divide
R the total by ten.
R If the average positive
R mismatch is less than
R 0.060 in. (1.5 mm) and no

in. (4.06 mm), it is acceptable for flight, if steps 1 and 2 are done:
1. All locations with an into the wind positive step mismatch of more than
0.060 in. (1.5 mm) must be repaired (Ref. SRM 54-02-05).
2. If, at one location only, the mismatch is large but not more than positive 0.160 in. (4.06 mm) you must adjust the fan cowl door (Ref. TASK 71-13-00-800-041) or you must do the repair for mismatch (Ref. SRM 54-10-00), Repair n.18. If the average positive step mismatch is more than
0.060 in. (1.5 mm) or there is more than one location with a positive step mismatch greater than
0.160 in. (4.06 mm) then replace the fan cowl door (Ref. TASK 71-13-11-000-041) and (Ref. TASK 71-13-11-400-041).
