Heads up #39
Revised main, and aft wing pin safety.
We have developed a more positive, yet simple to install, main and aft wing pin safety system. With any folding wing capable aircraft, the pilot has the responsibly to verify that the structural, and control connections are installed and have adequate safety devices installed.
Note - SPA has created a bracket kit for securing the wing pins. Please contact SPA to purchase this kit if your kit did not include the parts listed below.
Install parts P4516, P4517, P4518, P4519 per instructions in the Panther Builder Manual.
These are supplied with full kits after SN 91 and Forward Fuselage Kits ordered after 9/1/2017.
1. Safety wire the main and rear wing pins in place in a manor to prevent them from being removed
2. Install appropriate grade 8 bolts and lock nuts in place of main and rear wing pins.
Note: To prevent damage to the structure, these should not be fully tightened. The bolts should remain able to rotate.
