Plans Change #		Category	CP #	Location In Plans	Chap	Pg	Description
1		MAN-GRD	24	Section I	21	8	The Bendix fuel pump called out does not have a means of safetying the bottom cap.  This is done on certified aircraft as follows: Bend the small tab shown 90 degrees, drill a #50 hole in it, safety with .032 stainless safety wire, tied to the fitting.
2		MEO	24	Section I	19	10	Oops!  We forgot to include the tie downs in the Long-EZ plans.  Drill a 3/8" hole through the wings, 13" inboard along the leading edge, and 9.5" aft of the leading edge.  This will assure that you do not drill through the shear web, but will be just aft of the shear web.  Now flox a piece of aluminum tube into each wing, so that the tube is flush with the skins top and bottom.  3/8 O.D. x .049w  2024T3.  Obtain two AN4 bolts and make up a couple of removable tie downs as shown.  These can be stored in the centersection spar when not in use.
3		MEO	24	Section I			Sect VI See landing brake bushing revision below under VariEze plans change.
4		DES	24	Section I	21		Chap 7 & 21 See Safe-T-Poxy recommendation below for fuel.
5		MEO	25	Section I	5	1	Spacing between dimension on fuselage sides is 10", aft dimension is 3".
6		MEO	25	Section I	20	2	Add A,B,C, dimensions: A = 102.15"   B = 108.35" C = 118.35"
7		MEO	25	Section I	BACK COVER		Wing root leading edge should be 113.9", not 113.4"
8		MEO	25	Section I	19	9	Step 9.  Second line should read "form the 0.7" rib by removing foam with a rotary file".
9		MEO	25	Section I	19	6	Step 6.  Third line down LWA7 should be LWA2.
10		MEO	25	Section I	19	6	Lower right paragraph, LWA7 should be LWA2.
11		MEO	25	Section I	19	7	Bottom right, 3 lines up, LWA7 should be LWA2.
12		MEO	25	Section I	19	8	Bottom left, 2 lines up, LWA8 should be LWA7.
13		MEO	25	Section I	20	1	Step 1.  Third line down, Add page A3 and A14.
14		MEO	25	Section I	2	2	Airframe bolts AN3-11 should be AN3-11A
15		MEO	25	Section I	2	1	Tools.  Change "2 pcs 16 x 48" to "One piece 1/16" or 1/8" thick x 24" x 48"
16		MEO	25	Section I	10	2	Clarification:  Remove the word "centerline" two places, W.L. 19.4 is correct, but is not centered on the shear web.
17		MEO	25	Section I	4	2	Bottom right:  Clarification:  "both sides" means "left and right, on the forward face only"!  The foam doubler goes on aft face, with no additional plies at this time.  See Section A-A, B-B and C-C on page A3.
18		MEO	25	Section I	3	3	Jig table size omitted - add 3 ft x 11 ft.
19		MEO	25			A4	Engine mount extrusions "Chapter 6" should be "Chapter 14", 2 places.
20		MEO	25			A5	Clarification:  The 15 ply BID pad for the aft gear attach angle should stop at W.L. 12.35 (Don't glass above 12.35)(Chap 5).
21		MEO	25	Section I	2	4	Metal. "3 ft of 1.8 x 1" x 1" should be "3 ft of 1/8" x 1" x 1" aluminum angle"
22		MEO	25	Section I		A3	Correction.  Hole for gear retract drive tube should be 1" to the right of CL.
23		MEO	25	Section I	13	6	NG 31 is called out of R45 dark blue foam, should be R100 1/4" red foam, see page 2-3.  Also note on page 2-3 that F28 can easily be cut in one piece from the instrument panel foam sheet.
24		MEO	25	Section I	BACK COVER		Back Cover Nose gear CL is a W.L. -22 not -23.
25		DES	25	Section I	4	3	Aluminum can be substituted for the steel firewall, don't install fiberfrax now.  Wait until after cowling installation.  This allows you to wrap the fuselage skin around onto plywood and allows you to layup the 1 ply inside lip on the cowl lip. You will then have to remove things bolted to the firewall to install the fiberfrax and aluminum.  Install fiberfrax with silicone rubber, not epoxy.
25	a	DES	25	Section I	2	2	See changes for page 4-3
26		OPT	25	Section I			To save work and weight substitute UND for BID on centersection spar as shown on page 4 of this newsletter.
27		DES	25	Section I			For rough or grass fields and to relieve stress on nosegear components, install the spring assembly (page 8) in place of the NG 9/10A rod.
28		MEO	25	Section I	14	2	Step 4.  Outboard LWA 1 (sketch on left center of page) 1.0" dimension should be to outside of CS 5 and 8, not inside.  Change inside dimension to 0.75".  Be sure to transition edges of all metal parts with flox.
29		MEO	26	Section I	16	3	CS119 should be 4.1" not 3.1"
30		MEO	26	Section I	10	3	Upper right drawing #3 holes should be 1/4".
31		MEO	26	Section I	19	5	Lower left paragraph, 3 plies should be 2 plies.
32		MEO	26	Section I	19	3	Last paragraph, third sentence between "at" and "12" add "the correct place at the wing top.  Hot wire "0" to".
33		MEO	26	Section I	11	2	Lower left side, 3 lines up - should be 2 strips, not 3 strips.
34		MEO	26	Section I	2	1	LMGA is used in Chapter 5 not Chapter 9.
35		MEO	26	Section I	9	1	Landing brake paragraph - after the word "installation" add the words "and other important landing brake details".
36		MEO	26	Section I	19	15	Clarification:  CS127 can be made from the drawings on these two pages.  Use .032" 2024T3 aluminum.
36		MEO	26	Section I	19	16	Clarification:  CS127 can be made from the drawings on these two pages.  Use .032" 2024T3 aluminum.
37		MEO	26	Section I	8	1	Sides of roll over structure should be 13" not 12.7".
38		MEO	26	Section I	10	3	Two places, cut 12 pcs. UND should be, cut 6 pcs. UND.
39		MEO	26	Section I	26	1	VariEze canopy (Chapter 22) should be "Long-EZ canopy (Chapter 10)".
40		MEO	26	Section I	16	3	The AN 315-3 jamb nut shown is not supplied in the bill of materials.  It is satisfactory to substitute a MS21042-3 nut.  Run a 10-32 tap through the MS nut before installation.
41		MAN-GRD	26	Owners Manual		33	After "70 to 80 psi" add "75 to 85 psi for 6-ply tires".
42		OPT	27	Section I	4	2	Add "alternate the BID and UND plies that reinforce the sides of the forward face of F-22".  Note:  Modification is not required if you have already installed these without alternating.
43		MEO	27	Section I	18	7	Lower right "to firewall bulkhead" should be "to aft end of canopy frame FS 117" (two places).  See page 18-5.
44		MEO	27	Section I	10	1	Step 1 paragraph two Refers to two 7 x 14 x 41 blocks (two places), change this to one block.
45			27	Section I	9	3	Move the 3/8" holes in all four extrusions up 0.4".  Also modify outlines to maintain original edge distances around the 3/8" hole.  This moves the entire main gear up 0.4", resulting in an improved gear-fuselage juncture reducing aerodynamic drag.
46		OPT	27	Section I			Revise F28 bulkhead by moving the longeron notch down 0.25".  This raises F28, for better fit to canopy.
47		DES	27	Section I			Due to a probable rubbing of the rudder cable on the aileron pushrod, the left hand rudder pulley bracket should be moved up 0.6".  If you have already mounted the 3 bolts in the firewall such that you cannot make this change, you can provide cable clearance by carefully bending the rudder pulley bracket to move the pulley aft approximately 0.2".  Bend as shown below.
48		DES	27			A4	Increase size of firewall at top as shown to assure adequate height to fit cowling.
49		MEO	27	Section I	22	6	On circuit breakers, change "roll trim" to "fuel pump".
50		MEO	27	Section I	7	1	Section A-A.  This sketch is not accurate.  See page A2 for the correct full size drawing.  Also note LPC #46 in this CP.
51		MEO	27	Section I	10	1	Step 1 Refers to Chapter 13 for winglets, should be Chapter 20.
52		MEO	27	Section I	8	1	Roll over structure assembly 4.5" should be 4.0", moving shoulder harness insert outboard 1/2".
53		MEO	27	Section I	2	1	Add CLI and NG5 to Brock list.
54		MEO	28	Section I	24	1	Step 1, 3rd paragraph, glass with one ply of BID.
55		MEO	28		2	2	Bill of Materials AN970-4 Washers, should be 11 not 5.
56		MAN-GRD  Clarification CP #25	28	Section I			Page 6  Lower right corner.  Long-EZ spar cap thickness.  This box must be complied with.  Several builders have ignored this.  Do not omit this, you must have the prescribed amount of glass in the spar caps, in both the centersection spar and the wings.
57		MEO	28	Section I	3	23	Wet out Delete this paragraph entirely and add the following:  WET OUT - Squeegee cloth from center outward aligning the the fibers straight and removing wrinkles.  Pull the outside edges to straighten any wrinkles.  Brush or stipple epoxy into any dry areas or pour on additional epoxy and squeegee out uniformly.  Check for excess epoxy "ridge" with the squeegee.  (page 3-11).
58		MEO	28			A5	On the main gear mounting pads bottom of page, two places shows only 1 ply.  Should be 15 plies of BID.
59		MEO	28	Section I	21	6	Section F-F  The outside strips of UND glass, the third ply in layup #7 and #9 (shown on Page 21-4) has been omitted.  This should be shown on Section F-F (on the outside of the tanks, directly above layup #4 directly below #3).
60		MEO	28	Section I	21	3	Fifth paragraph.  1/4 - 27 NTP should be 1/8 - 27 NTP
61		MEO	28	Section IIL		37	Lycoming Engine Installation, bill of materials.  Engine mount hardware - under 8 #71032 rubber bushings, add:  OR 8 #6083 rubber bushings.  This choice will depend on the size hole machined into your engine.#71032 for 1" diameter hole and #6083 for 7/8" diameter hole.
62		MEO	28	Owners Manual		24	Add maximum landing brake extension speed - 95 kts.
63		MEO	28	Section IIC		3	Lycoming Engine Installation.  Third paragraph on the right.  MA3-SPA should be MA3-PA.
64		DES	28	Section I	19	17	Snub the aileron hinge pins per instructions in this newsletter.
65		MAN-GRD	29	Section I			There are indications that the back injury noted on accidents (pg 3) may have been caused by the center speed brake diagonal bulkhead being forced through the seat back after failure of the landing gear and the airplane's belly impacted the ground.  Refer to the sketch and remove the portion of the plywood bulkhead (part #LB9) shown to allow it to collapse without piercing the seat bulkhead.  Double check that the speed brake arm (#LB20 & #LB2) does not go over center with speed brake down - recheck the 40 lb. closure force.
66		MEO
67		MEO	29	Section I	5	3	Nuts on the AN6-80A bolt should be AN363-624, not MS21042-6.
68		MEO	29	Section I	4	1	Note at the foot of the page.  Remove "NOT" so that it reads, "micro slurry is used on this type R45 foam.  We do recommend slurry to be used on all of the various foams in a Long-EZ.
69		MEO	29	Section IIL		14	Conical engine mount.  The 7/8" O.D. x .049 cross brace tube must be moved down in order to clear the fuel pump.  It is shown in the correct position on page 15.
70		MEO	29	CP#28		8	Under builder hints, UND layups on the fuselage sides should be + 30 not + 45.  This is shown correctly in the plans.
71		MEO	29	Section I	2	1	Add to Ken Brock parts list - 4 spacers A4-84 and 2 nuts J1.25 (axle spacers and nuts).
72		MEO	29	Section VI		2	Landing Brake - part number LB10 should be changed to make the "ear" 1/2" longer to avoid interference with LB3.  If you bought this LB10 part from Ken Brock, this change has already been accomplished.
73			29	Owners Manual		66	checklist - After "canopy-locked" add "visually confirm proper canopy latch engagement and proper safety catch engagement".
74			29	Owners Manual		47	Add, CAUTION prop bolts - recheck torque (180 in.-lbs.) before next flight when a transition is made from a wet climate (high humidity) to dry conditions.  Wood shrinkage in dry environment can loosen prop bolts and result in flight loss of the entire propeller.
75		MAN-GRD	30	Section I	9	1 8	The axle bolt location in the sketch on the lower left is not accurate.  See sketch below.  Warning - Note that the 1/16" clearance between the main gear strut and the brake caliper is a mandatory requirement.  The caliper must not be able to touch the strut or the wheel pant or you could have an intermittent brake or even a brake failure.  The caliper must not be able to touch the strut or the wheel pant or you could have an intermittent brake or even a brake failure. LPC #75 Ensure a minimum of 1/16" clearance between gear strut and brake caliper.
76			30	Section I	11	5	See detail page 5.4 should read "see detail page 11-4".
77			30	Section I	19	18	Step 11. "Refer to chapter 6 and 7" should be "refer to pages 14-8 and 14-9".
78			30	Section I	?	?	Antennas.   Nav. antenna DES should be cut into two equal lengths from a 48" piece.  Change the length to 22.8" long, not 24".
79			30	Section I	2	4	Chapter 13 material list. SC fiberglass strut cover is listed twice.
80			30			A5	2" x 2" x 1/4" aluminum ext. shown full size page 18-3, should be page 9-3.
81		MAN-GRD	30	Section I	19	14	Section E-E. Detail A shows the rodend bolt on the CS 132L belhorn reversed.  Anytime a rodend is cantilevered off one side of a belhorn, the bolt head must be on the belhorn side, see sketches below: LPC #86, MAN/10HRS Reinforcement of top tab welded to the rudder pedal.
82			30	Section I	5	2	Step 2.  One ply of BID extend entire 103" length, this ply of BID should be at 45 degree and can be in several pieces.
82	a	Clarification	35	Section I	5	2	Plans Change LPC #82, CP 30, page 9.  This has been causing some confusion.  This change was simply to clarify the orientation of the one ply BID called out in Section I, page 5-2.  This ply is not an addition.  It goes full span along the longerons and l
83			30	Section I	9	4	The AN960-1018 washers called out should be AN960-1016 and are not called out in the bill of materials on page 2-4.  Add 4 more AN960-1016 to the 2 washers called out.
84	a	MEO	30	Section I	21	5	Step 10. We omitted to tell you to micro a urethane foam block (2 lbs.ft3 green) to the 'flat' leading edges of the strakes, see page 21-7, cure, then carve to match proper leading edge contour (ribs R23, R45 and the wing). Slurry the foam and lay up two plies of UND crossing each other at 45 degrees to the leading edge of the strakes.  Lap this layup 1/2" onto the strakes top and bottom.
85		MEO	30			A5	To right. "shown full size, page 18.3" should be "page 9-3".
86		MAN 10hrs	30		13	3	Rudder pedal weldments. Before 10 hours of flight the top tab welded to the rudder pedal (see section I, page 13-3) must be reinforced per Figure 2, page 5 this newsletter. Also change the full size drawings on page 13-3 to show the top tab per Figure 1, page 5 this CP.
87			30	Section I	13	4	Change wall thickness on NG17 to .188.  Change wire diameter of spring to .083.
88		MEO	31	Section I	19	16	Part #CS127 is made from .032 2024T3 aluminum.
89		MEO	31	Section I	9	3	Sketch on lower left of page shows brake line run between the gear strut and brake disc.  This is incorrect.  The brake line must run around the inboard face of the strut.  This puts the strut between the brake disc and the brake line.
90		MEO	31	Section I	20	4	Step 6, says see Section III, this should read, see page 22-3.
91		MEO	31	Section I	19	?	Covers for the access holes, three each side, for wing attachment can be fabricated out of .016 aluminum sheet, painted to match you airplane.  To install, stick over the hole using a small bead of RTV (silicone, clear silicone rubber sealant by Dow Corning is best). The covers should be taped or weighted into position and left to cure for at least 24 hours.  They are water-tight and keep the rain out of the attach area.  If you need to remove them later, a razor blade will easily cut them loose.
92		MEO	31	Section IIL			Oops!  We neglected to cover installation of the ram inlet scoop.  This prefab part should be installed onto the bottom cowl, permanently.  It is floxed into place, and has a flush "pop" rivet approximately every 2" around the flange. After cure, one ply of BID is layed up inside lapping 1" onto the cowl and the ram inlet.
93		MEO	31	Section IIL		36	Bottom left. AN823-4D should be AN816-4, also aeroquip 496-4 should be 491-4.
94		MAN 25hr	31	Section IIL		36	Remove the following aluminum fittings: AN822-6-2D  2 ,  AN816-6D  2,  AN823-6D  1,  AN912-1D  1,  AN823-4D   1 And -Install the following steel substitute fittings: AN822-6-2    2 , AN816-6  2,  AN823-6  1,  AN912-1   1, AN823-4   1. Refer to the adjacent circled items from Section IIL, page 36 to identify affected parts.  Make the appropriate changes to Section IIL, pages 13, 18 and 37.
95		DES	32	Section I	16	2	Step 3, paragraph 1, last sentence.  Pivot hole drilled to 23/64" (0.359).  This results in an extremely tight interference fit,(0.016) and it would work better using a letter "U" drill (0.368) & better yet if you then ran a 3/8" press fit reamer (approximately 0.373) through the hole.
96		MEO	32	Section I	21	5	Drawing at lower left. Material for fuel valve mounting bracket should be 0.062 2024-T3 aluminum.  The fuel valve handle should be trimmed down to clear the instrument panel.
97		MEO	32			A14	lower winglet, tip template. The arrow pointing inboard is correct, the words, "this side for lt......", etc. are reversed.  The side shown is for the right winglet, transfer numbers to the other side for left.
98		OBS	32	Section I	22	6	Center drawing. Delete "yaw trim bracket".
99		DES	32	Section I	14	10	Sections E-E, F-F, G-G & H-H.  The UND layup #3 & #4 are incorrectly shown to lap onto the CS7 & CS8 bulkheads.  The words describing this layup on page 14-2 are correct. Layup #3 & #4 are layed up onto CS2 & CS3 in Sections E-E & F-F and only onto CS1 in Sections G-G & H-H.  Applies also to 14-11
100		MEO	32	Section IIL		6
101		MEO	32	Section IIL		37	Add to the Brock parts list - two spacers, part #SP-5.  These spacers are used as stand-offs to bolt the gascolator to the firewall.
102		Clarification	32	Section IIL		37	CLARIFICATION.  Part #LL-4 is used to stand off the mixture cable clamp, and is shown as a 5/8" long stand off tube on page 16. Part #LL-3 (page 37) is used inside the AN111-4 bushings in the throttle & mixture arms, and is shown as a 1/4" x 3/16" x .25" spacer on page 17.
103		DES	34	Owners Manual		21	First paragraph, "carbon dioxide-type" should be "dry type fire extinguisher".
104		MEO	34	Section I	20	2	Second paragraph, "3rd ply is on the upper surface only" change "surface" to "winglet" to clarify.
105		MEO	34	Section I	6	3	The 1" x .7" x 3" wood doubler should be glassed over with 1 ply BID at 45 degrees, lapping .4" onto F28, top longeron and fuselage side.
106		DES	34	Section I	22	3	System II with alternator.  The wiring diagram does not show an alternator circuit breaker between the B plus alternator terminal and the battery.  This protection is very important and the circuit breaker should be sized to the maximum output of the alternator.  For example a 35 amp alternator should have a 40 amp breaker.
107		MEO	34	Section I	19	8	Step 10 clarification.  The root of the aileron should be cut at 90 degrees to the trailing edge along the line on the top skin to the hinge line defined by the 5.9 dimension. This cut is a vertical plane and will not pass through the point on the bottom skin that is defined by the 7.6" dimension.
108		MEO	35	Section IIL		7	The brake master cylinder is shown mounted on the inboard side of the CS73 bracket on Page 7, which is correct.  It is incorrectly shown outboard of CS73 on Page 13.
109		MEO	35	Section I	2	1	Add the following to the parts listed on page 2-1 of the Long-EZ plans under "custom prefab parts" by Ken Brock Mfg.;  Lycoming exhaust system, Dynafocal engine mounts,  Conical engine mounts,  A484 back up rings (4 required 2 each), JI.25 axle nuts (2 required),  LE2-LL landing light mount kit,  LMBG1 forward main gear attach brackets (2),  LMBG2 aft main gear attach brackets (2)
110			35	Owners Manual		22	Add the following to the Owners Manual, page 22 under "Engine Out" "A windmill start uses less altitude if you initially dive steeply to rapidly attain 135 knots"
111		MEO	36	Section I	16	4	Universal joint CS120, should be MS20271-B10, not AN271-B10
112		MEO	36	Section I	9	1	top right "Refer to Chapter 8" should read "refer to Chapter 14".
113		MEO	36	Owners Manual		32	Aileron mass balance - it reads "level to 10 degrees nose down", should read per Section I page 19-9 bottom left - "The aileron must hang between the angle that makes the bottom surface level and the angle that makes the top surface level after painting".
114		MEO	36	Section I	22	3	Gear and canopy warning wiring diagram.  For clarification add the correct call outs for each connection to each switch, i.e. C (common), NO (normally open), NC (normally closed).  See sketch pg 9.
115		MAN-GRD	36	Owners Manual		30	Bottom of the page add - "Builder experience has indicated that it may be possible to spin a Long-EZ when at or aft of the aft CG limit.  Analysis indicates that the spin mode or recovery would not be effected by power.   Recovery should be forward stick, rudder against rotation and ailerons neutral or with the spin rotation".
116	a		37	Owners Manual		30	Change aft limit from 104 to 103.
116	b	Note a1		Section IIL			The engine installation plans update and supercede information in Section I.  Do not do any work aft of the firewall without having Section IIL in your hands.
116	c	Note a2		Section IIL			Section IIL also has lots of information on engines, which may help you to make your selection.
116	d	MAN-GRD	39	Section I	23	3	CAUTION:  A number of builders have not installed the metal shields in the wing root areas as called out in Section I, Page 23-3 of Long-EZ plans. It is possible that exhaust system radiated heat can damage the foam in the root of the wing.  The metal shield eliminates this problem
117			40	Section IIL		10	The Lycoming #STD 619 washer should be replaced with an AN970-6 washer.  The Lycoming washer has too large a hole allowing it to slip over the 1.84" long spacer.  This allows the rubber bushings to be crushed more than they should be.
118			41	High Perf. Rudder		R2	Top left hand corner.  The sketch shows the hinge attach screws and nutplates to be on the rudder and the rivets to be on the winglet.  This is in fact reversed as can be seen in Photos #23 and #24. The hinge should be permanently mounted into the rudder with rivets and the attach screws and nutplates should be in the winglet.    Clarification:  The dimensions shown are what we used to mount these rudders in 3 different Long-EZs and are correct. The 39" dimension from the top of the rudder down to the "kink" in the rudder trailing edge is a reference dimension.  The "kink" in the rudder varies from plane to plane. To lay out the rudders on your winglet, follow the instructions exactly as called out on Page R-1.
119			43	Section I	14	7	parts #LWA4 and LWA5. Increase the size on 8 LWA4 from 1 1/2" x 2" to 1 3/4" x 2" and on two LWA5 from 2" x 2" to 2 1/4" x 2".  The increase is in the vertical dimension and is to allow more leeway when drilling the 5/8" wing mounting holes.  Several builders have come very close to the edge of these parts, a couple have actually broken out.  Breaking out is cause for rejection.
120			43	Section IIL		6	Paragraph 2.  There should be 4 AN509-10R8 screws in each top attach point.  LPC #100, CP32, page 7 incorrectly called this out as 3 screws.
