5.7 D-CELL NOSERIBS
The owner of a highly modified Lazair reported recently that several of the foam noseribs inside his D~el1 had moved out of position. This was one of the earlier kits with the .016 inch D~ell skin, (kits A192 and subsequent have a .020 inch D-cell skin) and was fitted with relatively heavy reduction units and very large propellers.
Although this is believed to be an isolated case, it is recommended that all owners check the position or their nose ribs occasionally (especially in the area or the engine nacelles). This can be done easily by tapping along the top or the D-cell (about 4 inches ahead or the main soar) and listening for the ribs. There should be a rib every 4 inches. if you should ever get an indication that two or more adjacent ribs are out or position, drill out a few rivets so that the D-cell skin may be lifted sufficiently to look inside (with the aid or a flashlight). Any displaced ribs should be repositioned and bonded in place with panel adhesive. To avoid loosening the D-cell skin, remove only as 'many rivets as necessary and use tools made from coat hangers to fish the ribs into position.
It should be noted that because of this possible problem, the use of Rotax engines on a Lazair with .016 inch leading edge skin is not recommended.
