Particular
things to check at Inspection.
There are a small a number of areas that seem to come up at inspection. In order to help the inspector spot these I have started a list that can be used.
The plates used at the bottom of the seat frame and also on the centre of the footrest are supposed to be fitted to the trike keel with the triangular point facing backwards. Whilst this is not critical for the footrest, it is important for the base of the seat. If this is fitted incorrectly the angle of the keel to trike will be incorrect.
Check that the front steering drop arms have been attached with the longer end forward. Several constructors have reversed these.
In order to check that the main trike frame has been correctly constructed mark a line on the front of the Trike pylon at 1000mm form the top of the keel. Mark a line on the keel 1180mm from the large hinge bolt. Now measure the distance between the two. It should be 1365mm±mm. Slight difference will occur dependant on slight variations in the seat frame and attachment eyebolts. The angle between the keel and the pylon is approx 77 degrees.
The thimbles used on the main flying wires are a little too large for the eyelets in the lower surface of the sail and consequently is necessary to squeeze these in slightly using soft jaw in a vice. Do not over do this.
The front sail attachment screws go through the eyelets hidden beneath the leading edge covers, not the eyelets in the lower surface.
