Original Rib Construction "BUILD IT LIKE THE DRAWING"
The Rose Parrakeet has been subjected to stress calculation and testing by engineers. Both Jack Rose and Foster Hannaford received FAA approval of stress analysis. This data covers both the 728 pound and the 860 pound gross weight airplane. A key word here is GROSS WEIGHT. If you increase weight without knowing specifically where you must increase strength you are entering a vicious cycle that detracts from performance and can be dangerous. Doug Rhinehart reportedly pushed the Parrakeet to limits that caused him concern. He also flew a 40 H.P. Parrakeet over the Rocky Mountains from New Mexico to Iowa. Few of us will ever demonstrate his intensity and zeal for flight. The Parrakeet will most likely satisfy our needs straight off the drawing. A decision not to modify will be rewarded by a buoyant and responsive aircraft, with balanced stresses and strains.

Parrakeet A-4C Wing Attachments Photos below are of Parrakeet Model A-4C wings built by John "Doc" Anderson for Rose Parrakeet S/N 103, NC14843 in late 70's. Photos were taken by Don Pellegreno in late 1999, after he had uncovered the twenty year old restoration work for inspection and recovering. Builders should note that Rhinehart Rose Parrakeet Model A-4C was structurally designed for an O-200 engine and "Aerobatic" certification. For this reason, A-4Cs have thicker (5/8" front & rear) wing spars than the previous Rose Parrakeet A-1s or A-4s. Photos courtesy of Don Pellegreno. Final three photos are from Larry DeCamp's restoration of Rose Parrakeet S/N 106, NC14866. Wing attachments built to A-4C drawings. Photos courtesy of Larry DeCamp. Please Note: Hannaford Aircraft Model D-1 plans reflect spar widths (5/8" & 1/2") consistent with Rose Parrakeet Model A-4 not Rhinehart Rose Model A-4C. |
