Installation of the Inboard Flap

WARNING: PUT THE SAFETY DEVICES AND THE WARNING NOTICES IN POSITION BEFORE YOU START A TASK ON OR NEAR:

THE FLIGHT CONTROLS
THE FLIGHT CONTROL SURFACES
THE LANDING GEAR AND THE RELATED DOORS
COMPONENTS THAT MOVE.

MOVEMENT OF COMPONENTS CAN KILL OR CAUSE INJURY TO PERSONS AND/OR CAN CAUSE DAMAGE TO THE EQUIPMENT.

WARNING: MAKE SURE THAT THE FLIGHT CONTROL SAFETY-LOCKS AND THE WARNING NOTICES ARE IN POSITION.

WARNING: MAKE SURE THAT THE GROUND SAFETY-LOCKS ARE IN POSITION ON THE LANDING GEAR. THIS WILL PREVENT UNWANTED MOVEMENT OF THE LANDING GEAR, AND THUS POSSIBLE INJURY TO PERSONS AND DAMAGE TO THE AIRCRAFT AND/OR EQUIPMENT.

WARNING: BE CAREFUL WHEN YOU USE CONSUMABLE MATERIALS. OBEY THE MATERIAL MANUFACTURER'S INSTRUCTIONS AND YOUR LOCAL REGULATIONS.

CAUTION: BE CAREFUL WHEN YOU DO MAINTENANCE TASKS ON THE WING TRAILING EDGE:

DO NOT CAUSE DAMAGE TO THE ELECTRICAL CABLE RACEWAYS.
DO NOT CAUSE DAMAGE TO THE ELECTRICAL CABLE INSTALLATIONS.
MAKE SURE THAT THE ELECTRICAL CABLES ARE INSTALLED CORRECTLY. INCORRECT INSTALLATION CAN CAUSE DAMAGE.

CAUTION: THIS PART IS A REMOVABLE STRUCTURAL COMPONENT (RSC), WHICH CAN BE MOVED BETWEEN AIRCRAFT. THUS IT CAN HAVE DIFFERENT OPERATION CONDITIONS AND A DIFFERENT LIFE RECORD (FLIGHT HOURS/FLIGHT CYCLES/CALENDAR) FROM THE AIRCRAFT IT IS INSTALLED ON OR REMOVED FROM. THE OPERATOR IS RESPONSIBLE FOR THE SPECIFIC TRACKING AND CONTINUED AIRWORTHINESS OF REMOVABLE STRUCTURAL COMPONENTS. INCORRECT MAINTENANCE OF THESE COMPONENTS CAN CAUSE A RISK FOR THE FLIGHT SAFETY.

Subtask 27-54-61-420-056-C ** ON A/C NOT FOR ALL

A. Install the Inboard Flap
(1) If necessary, install the hoisting sling (Ref. AMM TASK 27-50-00-400-002).

Alignment of the Outboard Cruise-Roller of the Inboard Flap. ** ON A/C NOT FOR ALL

(2) Make sure that the flap cruise roller (126), at the outboard end of the flap, is set to the minimum position.
(3) If necessary, remove the nut (123), collar (122) and serrated plate (124).
(4) Turn the eccentric (125) until the minimum alignment marks are aligned.
(5) Install the serrated plate (124), collar (122) and nut (123). Tighten the nut (123) by hand.
(6) Make sure that the flap is set to its lowest position. At this position:

The painted (red) marks of the spherical bearing are aligned, and/or
The hole of the spherical bearing is at its maximum aft position.

(7) If necessary, repair the painted (red) marks as follows:.

Flap to Flap Carriage Connection (Track 1) ** ON A/C NOT FOR ALL

(a) Use a Textile-Lint free Cotton - (Material No.14SBA1) made moist with Non Aqueous Cleaner-General - - (Material No.08BAA9) to clean the surfaces on which you will make marks.
(b) Identify the related surface(s) with a torque seal Varnish Polyurethane-- Marking Structure (Material No.04SAB2) .
(c) Let it dry.
(d) Apply a thin layer of Corrosion Preventive Compound-Heavy Duty Soft Film - (Material No.12ACC1) to protect the marked area.
(8) Use TAPE - ADHESIVE to keep the eccentric disc (114) in position on the inboard flap drive trunnion.

Interconnecting Strut - Location and Detail ** ON A/C NOT FOR ALL

(9) Make sure that the interconnecting strut (10) is safetied to the outboard flap with adhesive tape.
(10) With the hoist and the hoisting sling, carefully lift the flap and put it in position over the wing:

CAUTION: MAKE SURE THAT THE FLAP DOES NOT HIT THE AIRCRAFT STRUCTURE.

(a) Lower the flap with the hoist and engage the flap drive trunnion in the flap track carriage at the track 1 position.
(b) Lower the outboard end of the flap and engage the flap in the flap track carriage at the track 2 position.
(11) If necessary, use a clean Textile-Lint free Cotton - (Material No.14SBA1) made moist with Non Aqueous Cleaner-General - - (Material No.08BAA9) to clean the eccentric disc (114) and to remove the remaining adhesive tape.
