| Step 1: The
construction of the flap requires a flat work surface and
three cradles (three per flap, six total) to hold the flap
upright when riveting. Make some of them from the same
material supplied for the wing leading edge and tank cradles
as shown in Figure 1. Using an FL-1004 nose rib as a
template, cut out the cradles. As shown in Figure 2, cut
them slightly oversize to allow for padding such as duct
tape, to prevent scratching the skins. |
| |
| Step 2: Identify
all the flap components from Page 22-1. Adjust all rib
flange angles to 90 degrees except for the FL-1005-R Main
Rib whose spar attach flange must be bent to allow the rib
to angle inboard and hug the tapering fuselage. The match
holes in the FL-1001C Top skin and Fl-1002 Bottom Skin will
determine this angle. Cleco the FL-1005-R Main Rib to the
bottom skin at the inboard end as shown on Page 22-1. Bend
the rib's spar attach flange until it's parallel to the
forward edge of the skin. |

Step 3:
Layout and drill #40 the joggled portion of the three
Fl-1007-L Hinge Brackets as shown in Figure 3.
CAUTION: DO NOT DRILL THE JOGGLED PORTION OF THE FL-1007-R
HINGE BRACKETS AT THIS TIME. THEY WILL BE MATCH-DRILLED FROM
THE FL-1007-L HINGE BRACKETS WHILE ASSEMBLED ON THE
FL-1003-L SPAR. |
| |
 Step 4:
Make the outboard rod end rib subassembly by clecoing an
FL-1006 Doubler to an FL-1004-L Nose Rib as shown in Figure
4.
Final-Drill the 1/4" hole in the doubler and the
corresponding 1/8" hole in the rib using a 1/4" drill.
Match-Drill #40 the two 3/32" doubler holes into the
nose rib. Machine countersink these two holes in the doubler
for AN426AD3 Rivets, flush on the side indicated. |
| |
 Step 5:
Make the inboard rod end rib subassembly by clecoing an
FL-1006 Doubler to an FL-1004 Nose Rib as shown in Figure 5.
Final-Drill #30 the1/8" holes common to the two parts.
Final-Drill the 1/4" hole in the doubler and the
corresponding 1/8" hole in the rib using a 1/4" drill. |

 Step 1: Cleco
together two left hinge pair rib subassemblies which are
made up of an FL-1004-L Nose Rib and an Fl-1007-L Hinge
Bracket as shown in Figure 1.
Final-Drill the 1/8"
holes common to the two parts. |
| |
 Step 2: Cleco
together two right hinge pair rib subassemblies which are
made up of an FL-1004-R Nose Rib and FL-1007-R Hinge
Bracket as shown in Figure 2.
Final-Drill the 1'8"
holes common to the two parts. |
| |
 Step 3:
Flatten two FL-1008 Spacers if/as required since they may be
bowed due to the punching process.
Make sure they
nest between the FL-1007-l and FL-1007-R Hinge Brackets
without gaps.
If desired, drill optional lightening holes in the
spacers using the dimensions provided in Figure 3. |
| |
 Step 4: Cleco
together the center hinge subassembly using the parts shown
in Figure 4. Space the FL-1007-L & -R Hinge Brackets using
the washers shown and insert a 1/4" bolt to maintain
alignment.
Final-Drill #30 the nine holes common to
all six parts.
Caution: Do not drill the joggled portion of the
FL-1007-R Hinge Brackets. |
| |
| Step 5:
Disassemble the parts, deburr and reassemble using
clecos but do not reinstall the hardware. |

 Step 1:
Trim away the small tab which has no pre-punched hole on
all FL-1005-L and FL-1005-R Main Ribs as shown in Figure 1.
Trim only as deep as the notch, this will permit dimpling of
the rivet holes in the lower aft-most flange. |
| |
 Step 2:
Cleco the FL-1004-L Nose Ribs, FL-1005-L and FL-1005-R
Main Ribs, and the rod end rib, hinge pair, and the center
hinge subassemblies to the FL-1003-L Spar as shown in Figure
2. Make sure all rib flanges face in the direction shown.
Final-Drill #30 the holes common to these parts and to
the spar web.
