3.14.3 Propeller accessories. Accessory parts for propellers do not

require preservation. Items shall be individually packaged or wrapped to

prevent contact with adjacent parts. Accessories shall be placed in a single

wooden reusable box in such a manner as to prevent movement of the accessories

during transportation (see 3.7.8). The accessory box shall be in accordance

with MIL-B-233, type W, class 1. Materials for the accessory box shall be as

specified in 3.8.2.2 for multiple trip use. An index list of accessories

shall be as specified in 3.7.7. The use of dunnage as a filler material is

prohibited. The box shall be assembled with corrosion resistant (stainless

steel) screws. The top cover of the box shall be attached with hex-head

corrosion resistant (stainless steel) screws to permit ready removal and

installation. The accessory box shall be attached to the propeller blade by

banding or strapping to prevent the box from movement during shipment.

Accessories should not be placed in a manner to restrict the bore opening or

interfere with handling. In some cases it may be desirable to place wood

braces between adjacent blades and attach the accessory box to the brace.

Cloth impregnated rubber shall be placed between the accessory box and the

strippable coating to prevent damage. Accessory box skids may be cut to

conform to the blade surface contour. The accessory box shall be painted

white prior to marking.
