Why Upgrade to Metal Spar Wings
Modern metal spar wings increase structural stiffness, improve control feel, and deliver long-term durability over legacy wood-spar designs.
​
Structural Improvements
-
Leading-edge wrap and Z-brackets increase torsional rigidity and reduce aeroelastic deflection.
-
Double-gusset rib attachments with solid rivets provide symmetrical loading and long-term reliability.
-
Increased bending stiffness supports steadier roll response and smoother vertical lines.
-
​
In Flight Performance
-
Modest gains in cruise and stall performance
-
Quicker roll rate
-
Stronger vertical penetration
Representative results (airframe dependent):
+2–4 mph cruise | ~+2 mph stall | ~+5% rate of climb | ~+10% roll rate
Models & Eligibility
Model compatibility, strut style, and tank configuration are confirmed during your Online Wing Quote.
​
Gross Weight Increases
Eligible models:
7ECA | 7GCAA | 7KCAB | 7GCBC
(Updated Flight Manual required after installation)
8KCAB (180 hp) requires Service Letter 423.
All other models are not eligible.
​
AD Status
Current production wings have no active ADs.
The 1996 strut-attach fitting AD has been resolved; all subsequent wings incorporate the updated design.
​
Approval Basis

Metal Spar Wings — Frequently Asked Questions
​
Can I purchase just the metal spars and install them myself?
No. The metal spar wing incorporates redesigned ribs, tank supports, drag truss components, and structural attachments. Only a limited number of parts are common with legacy wood-spar wings. For structural integrity and proper fit, wings are supplied as complete assemblies.
​
Is there a kit option?
Individual components can be purchased, but factory-assembled wings are typically more economical and ensure proper fit, alignment, and quality control. Pricing reflects complete, fully assembled wings built with all-new parts.
​
Are there any Airworthiness Directives (ADs)?
Current production wings have no active ADs.
A 1996 AD addressed the strut-attach fitting and required replacement with an updated design. All wings produced since incorporate the revised fitting.
As required by FARs, all applicable ADs are complied with prior to delivery.
​
What is the approval basis and paperwork?
The wings qualify as replacement parts supported by FAA-approved factory drawings. Installation is logged referencing the provided drawing numbers. An installation print is included with delivery.
​
What about other metal spar wing conversions on the market?
Some STC-based conversions replace wood spars within the original wing structure. Our wings are complete factory-built assemblies designed around metal spars from inception. For a detailed comparison, see the Engineering Aspects of the Upgrade page.
​
How should installation be logged?
Installation is recorded in the aircraft logbook referencing the applicable factory drawing numbers, similar to:
“7-____ wings and 5-____ struts installed per 7-____ installation drawing.”
The required documentation is included with delivery.
​
How do I qualify for a gross weight increase?
Eligible models:
7ECA
7GCAA
7KCAB
7GCBC
A revised Flight Manual is provided after installation.
For 8KCAB (180 hp), Service Letter 423 must be followed.
All other models are not eligible.
