APPENDIX 1

MODIFICATIONS:

The following general modifications - pertinent to all Exemption aircraft -

must be incorporated on each Weedhopper JC-34-B microlight aircraft, in orderto comply with the requirements and to qualify for the issue of the IndividualExemptions:

INSPECTION

5605

S607

(i) Where, on Fuji Robin EC-334 powered machines, it is knownthat the reduction drive-shaft is of a material such as EN8,which is known to be unreliable on the type of system beingchecked, the shaft must be replaced with material to' at leastEN15T or EN24T specification.

r

Fire-resistant fuel-line(s) must be fitted for a distance of atleast 45cm (18 inches) from the engine and routed as far as

,possible on the opposite side of the engine to the exhaust.

An on-off fuel-cock must be installed in the fuel-line(s) UNLESSit can be shown that leakage from any part of the fHel-tank,fuel-lines or system cannot fall on to hot parts of the engine orexhaust. Fuel-cocks must have positive stops in the On and OFFpositions and these positions must be clearly marked.

The wiring for the ignition switch must be fire-resistantadjacent to the engine, or located so that, in the event of anengine fire - the engine can be stopped. (Wiring located forwardof fuel-carrying components is considered to satisfy thisrequirements) .

Where an altimeter is not permanently installed, a wrist mountedal timeter is acceptable. In such cases, a placard must beinstalled, stating ~learly that an altimeter MUSTBE CARRIED.

The aircraft MUST also be placarded with:(a) the Vne(b) the aircraft empty weight(c) the maximum cockpit-load

APPENDIX 1

The original, aluminium-alloy wing-tangsstainless-steel ones.

must be replaced with

A self-alignment block must be fitted between each axle-end and thestruts.

Twin, parallel plates must be installed at the fuselage-axle clusters,to place the relevant bolts in double shear.

If the control-column fouls the fuselage-frame at any position, amodified frame-attachment must be installed.

The rear fuselage-members must be braced between the sub-fin brace andthe two rear fuselage-braces.

The control-column pivot-assembly must be locked, to prevent rotation.

The original wing-struts must be replaced with larger diameter tubes,of 1.125 inch diameter x 17g or 1.500 inch x 20g seamless drawn HT30TFmateri'al.

The tailplane-attachment brackets must be modified to incorporate asleeved bolt, joining them to the V-brackets.

A duplicate spacer must be introduced below the main bolt at thecurved, upper ends of the fuselage-frame tubes, with a through-boltholding the tubes together.

The main axle must be replaced with a 1" 10swg T45 or 4130 steeltubular one, with a channel section over it to a) spread the load fromthe pilots seat, b) allow mounting of the control channels and seatwithout disruption of the axle and c) to avoid vertical holes in themain axle. This modification is drawn on sheet WH3a, issued 25/5/94.

The alternative modification is to use 1" 10 swg T45 or 4130 steel stubaxles fitting into 1 3/ 4"~ square HE30 aluminium blocks at least 60mmlong. The blocks fit into a 2 "x2" xl/8" wall extruded HE30TF boxsection. The inboard ends of the stub axles to be drilled 1/4" dia. notless than 25mm from the ends, and attached by a 1/4" AN bol t in doubleshear through the extrusion, block and axle. The scheme is described ina dimensioned sketch by type specialist P Lovegrove dated 26/5794.

11) Stops must be provided on the control system to prevent unsafe loadsbeing put into it, and to prevent elevator/rudder contact at theextremes of movement.
