GLOBAL'S UH-1 FIN SPAR REPAIR KIT
Time and Money. Save Both and Fix it Right

Our UH-1 Fin Spar Repair Kit provides an economical solution to the problem of fin spar cracking on the Bell UH-1 series helicopter and eliminates the need for x-ray, hammer tapping, or monthly inspections required by the FAA.

The primary advantage of Global's Fin Spar Repair Kit is that it is designed to be installed "in the field" without the use of a tailboom fixture and without removal of the tailboom. The kit includes a special disposable template to transfer the existing hole pattern to the new Global spar assembly. An experienced sheet metal technician can perform the installation in less than 80 man hours using simple shop tools.

The Global Spar is a robust design, utilizing high strength solid spar caps in lieu of the existing sheet metal spar. The spar caps run the full length of the spar assembly and are equal size on both sides. This feature increases the bending strength of the new spar by 60% versus the original spar. The center web is also thicker and stronger compared to the original web. Further, the new fin spar assembly eliminates the discontinuities present in the existing spar that have led to cracking at the top of the vertical fin.

Global's Fin Spar Repair Kit has been approved by the FAA for all UH-1 models under several Supplemental Type Certificates. At present, operators worldwide have installed over 1000 Global Fin Spar Repair Kits, and feedback from these customers has been overwhelmingly positive. The repair kits include all necessary installation hardware as well as extra fasteners to accommodate variations among aircraft. The Installation Instructions include step-by-step guidance, illustrated with color photographs. The kits are available for immediate delivery for all Huey models.
