DEFINITICNS: 

a. Line Ream - The simultaneous reaming of an alignment of holes in 

multiple layers of material that results in near perfect alignment of 

the holes. 

b. Cold Work - In the case of this Process Specification, the process of 

forcing an oversize mandrel through a hole at room temperature that 

permanently expands the diameter of the hole, creating a zone of 

residual compressive stresses around the hole. 

c. Stackup - Multiple layers of material that are considered as a single 

unit. In the case of this Process Specification, the spar cap, and top 

and bottom splice blocks together are considered a"stackup". 

d. STDN - Standard Tool Diameter Number - The numbering system used to 

identify specific size tooling, including reamers, mandrels, and 

sleeves used in this Process Specification. 

e. Starting hole - A properly drilled and reamed hole just prior to the 

cold work operation. 

f. Gage finish reamer - A reamer that includes a non-cutting, nondetachable pilot, sized such that it will not enter a hole with a 

diameter less than the reauired Dost-cold worked diameter.

Figure 1- Block Hole Numbering Scheme 

The lower wing spar cap and splice block holes will arrive at the wir+.g spar 

department machined 3/64" undersize final fastener diameter to allow the 

holes to be reamed or cold worked (as appropriate) to final diameter prior 

to spar assembly. 

The tooling used in this process consists of an alignment fixture clamped 

onto a vertical (CNC) mill table. The fixture holds the spar caps and 

splice blocks in near perfect alignment and allows precision reaming of the 

bolt holes in the cap/block stackup. The tooling is designed to allow all 

machiriing steps to be accomplished after a single set-up operation. 

The lower cap wing splice holes (#2 through #6) are line reamed only. 

These holes are first reamed to 1/64" undersize, and are then reamed a 

second time to final diameter. This 2-step ream process provides for 

excellent hole finish quality. 

The two outboard-most holes (#7 and #8 holes) in the lower cap wing splice 

will be line reamed to a"starting hole" size, cold worked using the 

Fatigue Technology, Inc. split sleeve cold expansion process, and then line 

reamed a second time to final hole size (nominal bolt size). 

PERSONNEL QUALIFICATION: 

Line reaming of the wing spar caps/splice block stackup and split sleeve 

cold expansion of bolt holes are both precision manufacturing tasks. The 

steps in this Process Specification shall only be performed by personnel 

who have attended an Air Tractor sponsored training course and 'nave 

r®ceived a certificate of completion for the Split Sleeve Cold Expansion 

process. This requirement may also be ful=illed bv attending a Fatigue 

Technology Inc. training session and receiving a Ce--t;ficate of Train.ina 

a-fter the ccmaletion of that training.

General Notes on Line Reaming and Cold Working Holes: 

3. eill rea~il;lg Operations are to be aCCCTDIished tising a vertical 

(CNL) mill machine. Water soluble cutting flu;d should be used 

for all rea:r,ing steps. 

2. Seiect reamers carefully to avoid misreaming holes. Reference 

Tabie 4 for proper rearners used during the Line P,eam process. 

~ . The stackup shall be securely clamped to obtain faying surface 

contact during line reaming, starting hole preparation, cold 

working, and final sixing. 

4. A surface upset is created during the cold working process at 

each hole face. This surface upset is normal. 

5. Sleeves may be stacked to obtain suf_`icient length. Total sleeve 

length shall be at least 1/32" greater than the material stackup. 

6. Sleeves are meant to be used only cnce. Sleeves must be 

discarded after use. 

7. Urient sleeve so that the split is pointing along the spar cap 

centerline facing inboard and the flared end is toward the puller 

nosecap. 

S. If axial slippage of the sleeve occurs in the hole during cold 

working, such that the end of the sleeve opposite the puller 

enters the hole, it is required that the hole be re-cold worked. 

PROCEDURE: 

1. Install lower splice block (21082-2), lower caps (21083-1 and -2) 

and upper splice block (21082-1) onto TSK544 tooling fixture. 

1.1. Place lower splice block (21082-2) into toolirtg fixture. 

Align lower block #1 holes with bolt holes in fixture. Splice 

blocks are steel stamped on one end with a release nurnber 

(XXXX-X), and on the other end with a part number (21082-1-L 

for the upper, 21082-2-L for the lower). The blocks must be 

placed in the fixture with the part numbered end on the side 

marked "LEFT WING". 

1.2. Carefully slide spar caps into fixture and align at #1 hole 

locations in lower block. Left spar caps (21083-1) must be 

placed on the side of the fixture marked "LEFT P7ING" and right 

spar cans (21083-2) must be placed on the side of the fixture 

marked "RIGHT WING". 

1.3. P'_ace upper splice block (21082-1) into fixtu=e. Align upper 

block rl holes with 4.1 holes in spar cans.

2.1. Select reamers carefully to avo?d m'sreaming holes. Re±erence 

Table 4 for proper reamers. 

2.2. Starting with the 42 holes on both left and right wings, ream 

both t2 holes in the lower cap using the 1 5Creamer size. 

2.3. Use compressed air to remove all cutting £luid residue and 

metal shavings from the holes. 

2.4. Repeat ream steps for holes 43 thru #6 one hole location at a 

time, moving outboard. Example, ream #3 lower cap holes next, 

then continue with 7114 holes, etc. 

3. Perform second line ream step (to final size) on #2 thru #6 holes: 

3.1. Select reamers carefully to avoid misreaming holes. Reference 

Table 4 for proper reamers. 

3.2. Starting with the #?_ holes on both left and right wings, ream 

botYi #2 holes in the lower cap using the 2 °d(final) reamer 

size. 

3.3. Repeat ream steps for holes #3 thru #6 one hole location at a 

time, moving outboard. Exarnple, ream #3 lower cap holes next, 

ttien continue with #4 holes, etc. 

3.4. Use compressed air to remove all cutting fluid residue and 

metal shavings from the holes. 

3.5. Inspect holes #2 through #6 to ensure diameters and hole 

sur£ace finishes meet the requirements of Table 5. Holes may 

be inspected using a ball gauge and micrometer, or air gauge 

with the proper calibrated hole standards. Measure hole 

finish using surface finish comparator plates or a
