15.Move flap control lever (4) from intermediate position
to FULL and then move it back to intermediate
position. The same results as in step 9. must be
obtained.
16.Check flap control for freedom of movement, absence
of interference and losses of hydraulic fluid.
17.Move flap control lever (4) to UP and check that the
clearance between the top surface of the inner flaps
and the wing trailing edge is between 0.078 in and
0.354 in (2 mm and 9 mm) , check that the clearance
between the top surface of the outer flaps and the
wing trailing edge is between 0.078 in and 0.354 in (2
mm and 9 mm) , (the outer wing trailing edge must not
be deflected by the flaps), check that the clearance
between the top surface of the outer flaps and the
trailing edge of the spoilers is between 0.078 in and
0.354 in (2 mm and 9 mm) (spoiler trailing edge must
not be deflected by the flaps), check that the
clearance between the flaps and the panels on the
outer wing underside must not exceed a value
between 0.314 in and 0.452 in (8 mm and 11.5 mm),
check that the clearance between the flaps and the
panels on the inner wing underside must not exceed a
value between 0.118 in and 0.413 in (3 mm and 10.5
mm), check that the clearance between the outer flap
and the inner flap is 0.393 in ± 0.118 in (10 mm ± 3
mm) and the clearances between the inner flap and
the fuselage are 0.787 in ± 0.196 in and 1.220 in ±
0.196 in (20 mm ± 5 mm and 31 mm ± 5 mm).
18.With flap control lever (4) to UP set the ailerons to
neutral position by operating one control wheel.
