All aircraft are pockmarked with access panels, inspection plates, fairings, fillets and fasteners. Except for this one. Half a dozen tiny screw-heads and a few hairline seams are the only interruptions in Symmetry's glassy surface. The Pitot tube is a minute opening in the nose of the left wheel pant. The fuel-tank drains on the belly are what the industry calls flush drains, which generally have an eighth-inch protrusion beyond the skin of the airplane. An eighth inch too far for Cory Bird, who totally remachined the stock push-up drains and mounted them in bushings that are, well, flush. Even the necessary cowling access door for the oil dipstick has no visible fastener; to open it, you reach into a cowling air intake and spring an internal latch.
